Introducing Enterprise Edge

Routing and IP Services

Enterprise Edge supports the following routing and IP Services:

• Routing Services
– IP Routing Protocol
– RAS Service and Dial In Capabilities for Management Purposes Only
– RIP
– Packet Filtering

• IP Services:
– DHCP
– DNS
– Web Caching

• VoIP (voice over IP) Service

1

VoIP is a term used in IP telephony for a set of facilities that manage voice
information delivery using Internet Protocol (IP). VoIP sends voice information
in digital form in discrete packets rather than in the traditional circuit­committed protocols of the public switched telephone network (PSTN). A
major advantage of VoIP and Internet telephony is that it avoids ordinary tele­phone service tolls.

VoIP derives from the VoIP Forum which promotes the use of ITU-T H.323 as
the standard for sending voice (audio) and video using IP on the public Internet
and within intranets. The VoIP Forum also promotes the use of directory service
standards so that users can locate other users and the use of touch-tone signals
for automatic call distribution and voice mail.

In addition, VoIP uses the real-time protocol (RTP) over IP to help ensure that
packets get delivered in a timely way. Using public networks, it is currently
difficult to guarantee Quality of Service (QoS). Better service is possible with
private networks managed by an enterprise or by an Internet telephony service
provider (ITSP).

When using VoIP a business positions Enterprise Edge as a gateway. The
gateway receives packetized voice transmissions from users within the
company and then routes them to other parts of its intranet (local area or wide
area network) or sends them over the public switched telephone network.

• IP Routing Overview

• Enterprise Edge IP routing specifics

• IP addressing overview

• Static routing

• Routing Information Protocol (RIP)

• Packet Filtering
– source address
– destination address
– IP Protocol ID
– TCP Port

IP Routing Overview

The Internet Protocol (IP) is the protocol used on the Internet to send data is sent
from one computer to another. Each computer on the Internet, called a "host", has
at least one address that id entifies it from all other computers o n the Internet. When
you send or receive data (for example, an e-mail or a web page), the message gets
divided into units called packets. Each of these packets contains both the sender's
Internet address and the receiver's Internet address.

A packet is first sent to a router that understands reads the destination address and
forwards the packet to an adjacent router that reads the destination address.This
routing process continues across the Internet until one router recognizes the packet
as belonging to a computer in its immediate neighborhood or domain. That router
forwards the packet to the computer whose address is specified.

Because a message is divided into a number of packets, each packet can, if
necessary, be sent by a different route across the Internet. Packets can arrive in a
different order than the order they are sent. Another protocol, the Transmission
Control Protocol (TCP) to put the packets in the right order.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

Using Enterprise Edge Services 23

IP is a connectionless protocol, which means that there is no established connection
between the end points that communicate. Each packet that travels through the
Internet is treated as an independent unit of data without any relation to another unit
of data. The packets get put in the right order because TCP, the connection-oriented
protocol, keeps track of the packet sequence in a message. In the Open Systems
Interconnection (OSI) communication model, IP is in layer 3, the Networking
Layer.

Enterprise Edge IP routing specifics

Using Enterprise Edge Unified Manager, you can perform the following routing
configuration options:

• Add or delete the interfaces to routing protocols

• Configure routing protocol options

• Add and delete static routes

• Add or delete filters

• Set filter actions

For instructions on configuring routing options, see Routing on page 85.
The followings table shows the Enterprise Edge IP routing protocols and the

precedence order when conflict or redundant routes occur.

Precedence IP Routing Protocols

1. Static Routing

2. SNMP

3. RIP v1 and v2

IP Addressing Overview

IP addresses follow the format nnn.nnn.nnn.nnn, where nn is a number between 0
and 255. For example, 192.123.4.56 or 10.1.1.1. IP addresses enable computers to
communicate to each other. Both servers and workstations on a network must have
IP addresses. There are two types of IP addresses:

Dynamic – A dynamic IP address changes. Dynamic IP addresses are assigned
to computers by an IP address server as the computer needs it. Usually there is
a particular range or scope of IP addresses that your network uses. With
dynamic IP addressing, a computer can have a different IP address every time
it connects to the network. Other devices need to know the computer’s IP
address so that they can communicate with it. The IP address server manages
the assignment of IP addresses to the client workstations.

Static – A static or fixed IP address never changes. It is assigned to a computer
permanently. The computer has the same IP address every time it connects to
the network and is known to other devices on the network by that IP address.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

24 Using Enterprise Edge Services

Static Routing

Enterprise Edge users can add static routes to the IP routing table. These static
routes take precedence over those routes chosen by routing protocols, such as RIP.

To add a static route, see Static Route on page 94.
Note: Ensure that users do not add a static route for default route 0.0.0.0 with mask

0.0.0.0. Enterprise Edge’s Net Link Manager automatically creates a default
route and adjusts it according to link status unless router or Net Link
Manager are running.

Routing Information Protocol (RIP)

RIP is a widely-used protocol for managing routing information in a self-contained
network such as a corporate intranet. RIP is classified by the Internet Engineering
Task Force (IETF) as one of several internal gateway protocols (IGPs).

A RIP router sends full updates, which list all the other hosts it knows about, to its
closest neighbor host every 30 seconds. The neighbor host sends the information to
its next neighbor, until all the hosts in the network know the routing paths, a state
known as network convergence. RIP uses a hop count to determine network
distance. Each host with a router in the network uses the routing table information
to determine the next host for the packet, until a specified destination is reached.

Enabling RIP on Network Interfaces

To run RIP on one or more network interfaces, go to the specific interface under
router and enable RIP. After you enable RIP for an interface, you do not have to
reboot the Enterprise Edge server for the changes to take effect.

Packet Filtering

A packet is a unit of data routed between an origin and a destination on the Internet
or on any other packet-switched network. When any file such as an e-mail message,
HTML file, GIF file or URL request, is sent on the Internet, the IP layer divides the
file into packets of an efficient size for routing. Each of these packets is numbered
and includes the Internet address of the destination.

Enterprise Edge supports basic (or stateless) packet filtering for IP. You can
configure the filter to pass only the packets from the routes they list, or to pass
everything except the packets for the routes they list.

Each route in the list can be any combination of the following packet filtering
features. By default, no packet filer is configured.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

Using Enterprise Edge Services 25

Enterprise Edge supports the following packet filtering features for IP:

Packet Filter Feature Comments

Source Address the source address field of the packet to be filtered.
Source Mask the source address mask of the packet to be filtered.
Destination Address the destination address field of the packet to be filtered.
Destination Mask the destination address mask of the packet to be filtered.
Protocol the protocol type of the packet to be filtered.
Source Port the source port of the packet to be filtered. This field applies

only if protocol value is TCP or UDP.

Destination Port the destination port of the packet to be filtered. This field

applies only if protocol value is TCP or UDP.

ICMP Type the ICMP type field of the packet to be filtered. This field

applies only if protocol value is ICMP.

ICMP Code the ICMP type field of the packet to be filtered. This field

applies only if protocol value is ICMP.

Note: When you set filters, you must forward packets going to the RPC port (port

135 TCP or UDP) for correct Unified Manager operation.

LAN-to-LAN Fast Path Routing

Enterprise Edge provides an optional second 10/100 LAN interface. If the second
LAN interface is used, Enterprise Edge uses optimized software for high
performance routing. This includes an innovative design that speeds up the
performance for LAN-to-LAN routing by over three times the rate that is normally
achieved using traditional software architecture.

Dynamic Host Configuration Protocol (DHCP)

DHCP (Dynamic Host Configuration Protocol) is a protocol that lets network
administrators manage and automate the assignment of Internet Protocol (IP)
addresses in an organization's network. Using the Internet's set of protocols (TCP/
IP), each machine that can connect to the Internet needs a unique IP address. If an
organization sets up its computer users with a connection to the Internet, an IP
address must be assigned to each machine.

Without DHCP, the IP address must be entered manually at each computer. If
computers move to another location in another part of the network, a new IP address
must be entered. DHCP lets a network administrator supervise and distribute IP
addresses from a central point and automatically sends a new IP address if a
computer connects to a different place in the network.

You can set up Enterprise Edge to be your LAN’s DHCP server and let it assign IP
addresses to the workstations on your LAN as they need them. This is the
recommended configuration.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

26 Using Enterprise Edge Services

If you set up the Enterprise Edge server as a DHCP server, you must let all of your
workstations know that they will have their new IP addresses assigned by
Enterprise Edge. To do this, you may need to change the configuration of each
workstation individually.

If you already have a DHCP server, you must let it know that the Enterprise Edge
server is their gateway and DNS proxy for the workstations.

Your Enterprise Edge server can function as a DHCP server. You can use this
feature if you do not want to administer static IP addresses for every workstation on
your network. You can configure Enterprise Edge to assign IP addresses
dynamically.

Automatic Configuration using a DHCP server

To configure the DHCP server, you need to create a particular range (or scope) for
each LAN interface in Enterprise Edge and allocate a block of IP addresses for that
scope. The Enterprise Edge Auto-Configure system automatically creates a scope
using parameters inherited from the LAN interface.

Guidelines for Using DHCP

Since many default DHCP parameters are inherited from LAN interface
parameters, configure LAN interfaces before configuring DHCP.

If you are modifying the DHCP configuration on Enterprise Edge, follow the same
guidelines of your organization. In particular, you can perform one or more of the
tasks listed below to ensure proper operation of the networked system:

1. If a change in the DHCP configuration resulted in the change of ‘Router’ and
‘Subnet mask’ options in a scope, users must do one of the following to
ensure basic operation:

• Execute ipconfig /release and ipconfig /renew on each of the workstations.

For Windows 95 and Windows 98, use its equivalent, winipcfg.

• For clients that do not support ipconfig and winipcfg, reboot is required to

renew their IP addresses.

2. If change in DNS server or DNS name options happens, users need to repeat
the tasks in step 1 to ensure proper connectivity with the organization.

3. Always schedule a down time associated with these changes.

4. Nortel Networks recommends that you reboot Enterprise Edge to initialize
changes.

Using Enterprise Edge, you can define a DHCP scope for each LAN interface.
DHCP server parameters are divided into two categories: global and scope specific.
Global parameters apply to all scopes. Specific parameters apply to a specific
scope.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

Domain Name Service (DNS)

The domain name service (DNS) is the system within the Internet t hat maps names
of objects, usually host names, into IP numbers or other resource record values. The
name space of the Internet is divided into domains. The responsibility for managing
names in each domain is usually delegated to systems in each domain.

Enterprise Edge functions as both a gateway to the Internet and as a DNS proxy:

• Gateway: a system that links two different types of networks and enables them
to communicate with each other. Enterprise Edge is the gateway that links your
company’s network to the Intranet or Internet. Depending on your
configuration, you can let your workstations know that Enterprise Edge is your
Internet gateway.

Note:If your PC is a DHCP client under Enterprise Edge, you do not have to do

this.

• DNS Proxy – A Domain Name Service (DNS) proxy translates alphabetic
domain names into computer-readable IP addresses. For example, the domain
name www.nortelnetworks.com for the Nortel Networks web site can translate
to the IP address 192.177.5.18. After a domain name is translated into an IP
address, the workstations on your network can communicate with the web site.
Depending on the configuration of your system, you can let your workstations
know that Enterprise Edge is the DNS proxy.

Using Enterprise Edge Services 27

When Enterprise Edge receives DNS requests from clients, it first checks its local
cache for name entries and records. If found locally, Enterprise Edge immediately
responds to clients. Otherwise, Enterprise Edge creates a new DNS request to the
remote Primary or Secondary DNS servers on behalf of the client. If the remote
DNS server responds with the requested records, they are forwarded to clients and
cached in Enterprise Edge.

Note: If your PC is a DHCP client under Enterprise Edge, you do not have to let

your workstations know that Enterprise Edge is your DNS server.

Guidelines for Using DNS

Consider the following guidelines when using DNS:

• If the Enterprise Edge DNS service is enabled, make sure that clients always use
Enterprise Edge as their DNS server.

• When it is disabled, set the DNS Server field in DHCP configuration to the
remote DNS server IP address. If DHCP service is also disabled in Enterprise
Edge, tell all clients to set the DNS server in their IP configuration to the remote
DNS server.

• The DNS proxy carries security features because it keeps all of the internal IP
addresses from external web servers.

• You are required to fill in the remote Primary DNS server IP addres s. See DNS
on page 84 for instructions.

Web Caching/Proxy

When you use Enterprise Edge as a web proxy, Enterprise Edge can store or
cache information downloaded from the Internet. A proxy is a server that acts on
behalf of another. Web caching allows LAN workstations to share common
information downloaded from the Internet.

Data is usually cached on individual workstations. Each time a workstation on the
LAN requests information from the Internet, the individual’s request is sent to the
Internet, and the information is returned to their workstation. If multiple LAN
workstations request common data, a web cache on the network reduces download
time from the Internet.

With Enterprise Edge configured as a web proxy with web caching:

• LAN workstations have shorter download times.

• Previously downloaded information is stored for future use by all workstations
on the LAN.

• Enterprise Edge retrieves information from the Internet only if it is not already
cached or if the cached file is out of date compared to the information on the
Internet.

• Cookie blocking protects users’ privacy.

You can configure the web caching settings through your web browser.
The web proxy also provides security features similarly to the DNS proxy because

it hides all of the internal browsers’ IP addresses from external web servers.
External web servers see Enterprise Edge’s IP address.

Guidelines for Using Web Caching/Proxy

The Enterprise Edge web proxy uses a web server for running in HTTP-Proxy
mode.

Consider the following guidelines when using web caching/proxy:

• A web server installed in Enterprise Edge can not be used as a general purpose
HTTP server. It is only used by the Enterprise Edge web-based management
client and web-cache services.

• If users need to run their web sites, they need to run the HTTP Server on another
system and make its IP address known to Enterprise Edge.

To set the web server as the web cache/proxy, refer to Web cache on page 126.

SNMP Overview

Simple Network Management Protocol (SNMP) is the protocol that governs
network management and the monitoring of network devices and their functions.

Guidelines for Using SNMP

Consider the following guidelines when using SNMP:

• You can set read-only and read-write community names.

• You can set a list of permitted managers. When set, the agent responds to
requests from SNMP managers from only those IP hosts.

• An empty list of permitted managers implies that agent responds to requests
from anyone.

Using Enterprise Edge Services 29

• You can set trap communities. Each trap entry identifies the community name
that must be used and the manager addresses.

• You can enable or disable sending authentication traps.

• You can enable or disable the SNMP agent.

• At present, SNMP supports only MIB-II (RFC 1213) MIBs.

QoS overview

On the Internet, Quality of Service (QoS) is the methodology that transmission
rates, error rates, and other characteristics can be measured, improved, and, to some
extent, guaranteed in advance. QoS is of concern for the continuous transmission of
high-bandwidth voice and video multimedia informati on. Transmitting this content
dependably is difficult in public networks using ordinary “best effort” protocols.

Real-time applications that include voice and video are time-sensitive. Delivering
voice and video over the Internet requires bounded packet delay and jitter.
Differentiated Services (DiffServ) is a QoS framework standardized by IETF that
focuses on DiffServ standards for real-time and mission critical applications. The
DiffServ standards are evolving and vendors are starting to develop network
devices that support DiffServ.

The purpose of the Enterprise Edge QoS module is to prioritize IP traffic and to
provide an acceptable quality of service to delay and jitter sensitive applications
such as audio and video as well as mission critical applications.

The Enterprise Edge QoS module primarily serves two purposes:

• In a DiffServ network, it acts as an edge device and performs the packet
classification, marking, and prioritization.

• In a non-DiffServ or legacy network, it manages the WAN link to make sure
premium voice (and optional video) packets get high priority when crossing the
slow WAN link in both directions.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

Using Enterprise Edge Services 31

DiffServ Networks

For DiffServ networks, Enterprise Edge:

• Intercepts all H.323 traffic

• Identifies call setup packet

• Performs admission control based on the WAN link usage

• Marks the packets as premium once admitted

Enterprise Edge implements the DiffServ queuing model that includes a premium
queue and eight best-effort queues. The premium queue has a stricter high priority
than the best-effort queues. The eight best-effort queues are scheduled by a
weighted-fair-queuing (WFQ) algorithm. Since best-effort traffic is not shaped and
does not go through the admission control process, the WFQ is needed to avoid
starvation of low priority packets.

Currently, H.323 traffic is allowed to get into the premium queue. Users can allow
other traffic to be premium by setting up priority filters on the web-based GUI using
the following filter criteria:

• Source IP address (with mask)

• Destination IP address (with mask)

• IP protocol ID (e.g. TCP, UDP, or ICMP)

• Source port range

• Destination port range

• Incoming TOS field

Note: There is no traffic shaping mechanism implemented in this version. Be

cautious when setting up premium priority filters. If the traffic is high
volume and with high bursts, it may impact VoIP quality. Unless necessary,
Nortel Networks recommends that you allocate traffic to the high priority
best-effort queues instead of the premium queue.

Legacy Network

In a legacy network, Enterprise Edge assumes that network devices, such as routers
and switches, do not recognize the IP header TOS field (as defined by DiffServ) and
do not perform the corresponding priority processing. However, most of the current
installed routers, including those from Cisco and Nortel Networks, allow
administrators to set up priorities by IP addresses, port numbers or protocol types,
which is similar to the priority filters described above.

Note: This information is specific to H.323 traffic in legacy networks.
In this environment, Enterprise Edge allows H.323 voice (and optional video)

packets to travel across the WAN link with high priority in both directions using
existing router features.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

32 Using Enterprise Edge Services

An administrator needs to reserve a block of UDP port numbers and configure them
as high priority in both Enterprise Edge and the remote router at the other end of the
WAN link. Enterprise Edge forces all of the admitted H.323 streams to fall into the
reserved port range by using a proprietary technique so that these H.323 voice
(video) packets can get high priority. This is completely transparent to the end
H.323 terminals.

See Appendix B: Setting Up Remote Routers on page 167 for additional
information on setting UDP port ranges for remote routers.

Note: If an administrator configures all routers in their corporate network

with the same reserved port numbers (both in and out), admitted H.323
streams can get end-to-end high priority. However, routers connected
to WAN links are more critical because they are typically the
bottlenecks.

You can set up best-effort traffic priorities through the web-based Unified Manager
by using the following filter criteria:

• Source IP address (with mask)

• Destination IP address (with mask)

• IP protocol ID (e.g. TCP, UDP, or ICMP)

• Source port range

• Destination port range

• Incoming TOS field

There are a total of 8 priority classes for best-effort traffic in Enterprise Edge. By
default, all best-effort traffic is sent to Class 5 (queue 5), with Class 1 the highest
and Class 8 the lowest in priority.

Admission Control

Enterprise Edge allows users to set a certain percentage of the WAN bandwidth for
premium traffic. This traffic takes strict priority over best-effort traffic. In this
version, H.323 (VoIP) flows need to pass the admission control process to be
treated as premium traffic.

For admission control, Enterprise Edge uses the WAN Premium Bandwidth
parameter. Specifically, for each H.323 flow, QoS performs admission control
using the negotiated coding algorithm. A flow is admitted a s a premium flow if the
current total WAN premium usage plus the new flow is lower than the allocated
WAN premium bandwidth.

Otherwise, the flow is rejected and he flow is still delivered as best-effort traffic.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

Using Enterprise Edge Services 33

As a reference point: for a typical G.729 codec, each VoIP flow requires the
following WAN bandwidth, depending on the codec sample rate:

G.729 Sample Rate

10.6 k 14 k 24 k

8 k 10 k 16 k

Sample Rate
20 ms

Sample Rate
10 ms

Note: The calculation is based on a full-duplex WAN link with HDLC overhead

and VoIP with silence suppression.

Nortel Networks recommends that for slow WAN links, such as a 56K leased line
or ISDN, H.323 video is not configured as premium traffic.

Packet Marking for DiffServ Networks

Enterprise Edge classifies traffic and marks packets by setting the IP header type of
service (TOS) field. By default, the following items are classified as premium
traffic:

• All VoIP flows

• RIP packets: routing packets are periodically exchanged between Enterprise
Edge and remote routers. These packets need higher priority than regular
packets to ensure that the routing protocol is working properly.

• ICMP packets: Enterprise Edge Net Link Manager uses the ‘ping’ command to
decide whether the primary WAN link is active or inactive. These packets are
not delayed by regular packets.

• UDP Port 5000 packets – Enterprise Edge VoIP QoS Monitor uses port 5000 in
a proprietary protocol to monitor the IP network delay and jitter. Since
Enterprise Edge assigns VoIP packets to the premium queue, it also gives these
monitor packets high traveling priority.

• Admitted RTP/RTCP packets.

In Enterprise Edge, there are two places a user can set up a TOS field in an IP
header:

TOS-for-Premium-Traffic – this field sets TOS bits for premium packets for
DiffServ networks. If this field is ignored, Enterprise Edge uses a default value
of 0xB8.

TOS-for-Priority-Filters– this field sets TOS for those packets matching a
specific priority filter.

Note: You can specify packets matched to a filter to go Priority Queue 0 – 8. The

Queue 0 is for premium packets, and Queue 1 – 8 correspond to best-effort
priority classes 1 – 8.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

34 Using Enterprise Edge Services

If you specify Queue 0 and a TOS bits for a filter, then this TOS takes
precedence over the TOS set for premium traffic for all packets tha t match this
filter.

The default TOS for all best-effort packets is 0x00, and the default queue for
best-effort packets is Queue 5.

WARNING

Premium flows that are specified by priority are not admission controlled. Unless
you know the behavioral characteristics of a flow, do not specify flows as premium.
Instead, you can specify them as the highest B-E traffic.

Consider the following guidelines when you set up priority filters

• The fewer the conditions to check for, the fewer CPU cycles are consumed.
Filter processing is faster if fewer conditions are specified, without
compromising the precision in selection.

• If you don’t need the value of a particular criterion, such as source port number,
don’t set a corresponding value for the filter.

• When you specify the layer 3 sub-protocols, use the port number/IP address
combinations and avoid specifying the protocol field. Nortel Networks
recommends that you specify a protocol field only if you manage an unusual
condition in your network. This reduces the consumption of CPU cycles.

• Users can configure the precedence of the filters. Packets are matched against
each filter sequentially until a match is found. Pay attention when specifying the
precedence of filters. Placing ‘popular’ filters ahead of ‘unpopular’ filters can
significantly speed up the processing.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

Using Enterprise Edge Services 35

Port Range Setting for Legacy Networks

Enterprise Edge uses UDP port ranges to provide high priority to VoIP packets in
existing legacy IP networks. These same port ranges must be reserved and set to
high priority on all routers that an administrator expects to have QoS support.
Reserving port ranges is not required for DiffServ networks.

You can select any port ranges that are not used by well-known protocols or
applications.

Each H.323 or VoIP RTP flow uses two ports. The total number of UDP port
numbers to be reserved depends on how many concurrent RTP flows are expected
to cross a router interface. In general:

• Backbone routers reserve more ports than edge routers.

• Edge routers’ port ranges are a subset of the backbone router port ranges.

• Add UPP 5000 to high priority.

• Enterprise Edge’s port ranges are a subset of the remote router’s port ranges.

• You must reserve two ports for each voice call you expect to carry over the
WAN. You need two ports for each video session if it is given premium
treatment.

• You can reserve multiple discontinuous ranges. Nortel Networks requires each
range meet the following conditions:

- Each range must start with an even number.

- There must be an even number of ports in a range.

See Appendix B: Setting Up Remote Routers on page 167 for additional
information on setting UDP port ranges for remote routers.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

36 Using Enterprise Edge Services

Relationship between the QoS Module and the VoIP QoS Monitor

The VoIP gateway in Enterprise Edge includes a Quality-of-Service Monitor
(QMON) that periodically monitors the delay and jitter of IP networks between two
peer gateways by using a proprietary protocol. These monitoring packets are
delivered at UDP port 5000.

The main objective of the QMON is to allow new VoIP calls to fa ll-ba ck to PSTN
if the IP network is detected as “bad”.

The QoS module discussed here complements QMON. While QMON passively
monitors the IP network, the QoS module actively improves the IP network by
giving VoIP packets higher priority to travel so that the chance for QMON to detect
“bad” is reduced.

Note: For a VoIP call, if a packet passes QMON but fails the QoS admission

control, it is delivered over IP but only as a best-effort flow. There is no fall
back to PSTN if a packet has passes QMON checking.

QMON packets travel at the same priority as VoIP packets or at higher priority than
normal IP packets. If VoIP packets travel at a premium level but QMON packets
travel at normal best-effort level, it is possible for QMON to report the IP network
as “bad” and start to PSTN fall-back, but the actual delay and jitter for VoIP packets
are still “good”, since VoIP packets have a higher priority. To avoid this add UDP
port 5000 to the high priority queue in all routers.

Enterprise Edge QoS Restrictions and Defaults

Enterprise Edge QoS includes the following restrictions and defaults:

• By default, the general bulk of traffic (not defined by priority filters) is routed
to best-effort Queue 5 (with Queue 1 the highest priority and Queue 8 the
lowest). An administrator can define four classes of traffic above the generic
traffic and three classes below it.

• A maximum of 31 priority filters for best-effort traffic can be created.

• The QoS module can be optionally turned ON or OFF. The default setting is on.

• The predetermined WAN bandwidth is always available to VoIP gateway
channels. That is, VoIP gateway calls are always admitted. The remaining
WAN premium bandwidth can be used by other H.323 streams, such as
Microsoft NetMeeting. If there is no VoIP gateway traffic, their WAN
bandwidth can be used only by best-effort traffic, not other premium traffic (for
example, Netmeeting). Enterprise Edge does not support preemption of
admitted premium streams.

• Currently packet prioritizing and priority filters apply only to outbound traffic
for specified interfaces. Inbound traffic is treated on a first in first out (FIFO)
priority.

• The maximum port numbers a user can reserve for premium traffic is 256.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

LAN Connections

The Enterprise Edge Ethernet / 802.3 interface supports IEEE 802.3 Ethernet frame
format. The Ethernet interface uses Carrier Sense Multiple Access with Collision
Detection (CSMA/CD) to manage the access to the physical media.

Enterprise Edge Ethernet interface supports the following features:

• 100 BASE – TX with RJ-45 connector

• 10 / 100 Auto Sense

• Full Duplex support

• Fast LAN-LAN routing

WAN Connections

This section includes information on:

• WAN overview

• Permanent WAN connections:

Using Enterprise Edge Services 37

– Frame Relay
– PPP

WAN overview

A WAN (wide area network) is a geographically dispersed data communication
network. The term WAN distinguishes a broader data communication structure
from a local area network (LAN). A WAN can be privately owned or rented, but
usually connotes the inclusion of public (shared user) networks.

Enterprise Edge includes two primary WAN links (WAN1, WAN2) and a backup
WAN dial up link (WAN3).

• The Primary WAN link is always a permanent link and it is a dedicated network
adapter. The primary link runs either Frame Relay or the PPP protocol at the
link layer.

The Enterprise Edge primary WAN connection is through a two-port card.
These two ports can be independently configured to run Frame Relay or PPP.
The card includes one serial sync port and one T1 port.

• The backup WAN link is always configured as dial-on-demand network adapter
by the router. The backup Wan link runs PPP only. Enterprise Edge provides
backup WAN connection through a V.90 modem.

The primary and backup link management is performed from Enterprise Edge.
There is a Net Link Manager running in Enterprise Edge that monitors the
primary link status and it starts the backup link when a break in primary link is
detected. Similarly, the backup link is automatically terminated when the
primary link becomes active.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

38 Using Enterprise Edge Services

Note: Net Link Manager can back up only one link, even though there are two

primary links. Net Link Manager backs up the link whose next hop address
is given to it.

• Net Link Manager manages the default route in Enterprise Edge. If a link
breaks, Net Link Manager removes all the default routes on the broken link and
adds the default route to the new link. This happens during switch over from
primary to secondary links and vice versa.

Permanent WAN Connections

This section includes information on the following topics:

• Frame Relay

•PPP

The permanent WAN connections are provided by a WAN card that supports PPP
and Frame Relay connections. Each port can be configured to run either of the
protocols independently.

The WAN cards are provided by one T1 port (with in-built CSU/DSU) and one
serial sync port or dual serial sync port versions.

The Enterprise Edge serial sync port supports the following:

• Interfaces: V.35, RS442, RS 323, X.21

• Maximum line speed:8 Mbit/sec

Frame Relay

Enterprise Edge supports Frame Relay in group mode. That is, for each physical
port (serial sync or T1 port), there is one IP address for all PVCs.

The available DLCI numbers are 0-1023, of which 16 are reserved. The maximum
number of PVC’s allowed is 1008.

For Frame Relay network, Enterprise Edge supports Frame Relay Forum standard
FRF.9 compression protocol with the standard STAC compression algorithm.

Software performs the compression and it can be enabled or disabled by using
Unified Manager.

PPP

Point-to-Point Protocol (PPP) is a protocol for communication between two
computers using a serial interface, typically a personal computer connected by
phone line to a server. For example, your Internet server provider may provide you
with a PPP connection so that the provider's server can respond to your requests,
pass them on to the Internet, and forward your requested Internet responses back to
you. PPP uses the Internet protocol (IP). PPP is sometimes considered a member of
the TCP/IP suite of protocols. Relative to the Open Systems Interconnection (OSI)
reference model, PPP provides layer 2 (data-link layer) service.

Enterprise Edge Networking Operations Guide P0910464 Issue 01

Using Enterprise Edge Services 39

PPP is a full-duplex protocol that can be used on various physical media, including
twisted pair or fiber optic lines or satellite transmission. It uses a v ariation of High
Speed Data Link Control (HDLC) for packet encapsulation.

PPP can process synchronous as well as asynchronous communication. PPP can
share a line with other users and it has error detection.

PPP on the primary WAN link uses synchronous point-to-point communication.
Because the physical media is point-to-point, authentication attributes are not
supported in this mode.

Enterprise Edge supports PPP Compression Control Protocol (CCP) (RFC 1962)
with STAC compression algorithm.

This compression is done by software and can be enabled or disabled by using a
parameter in PPP configurations.

Backup Up WAN Connection

In Enterprise Edge, the back up WAN connection is a V.90 modem that is used as
a dial-up WAN link.

The modem is provided through an RJ-11 connector. The modem has the following
features:

• V.90 56 kbps ITU standard

• V.34 33.6 kbps ITU standard

• V.42/MNP 2-4 error control

• V.42 bis/MNP 5 data compression

• Compatible with ITU and Bell Standards from 56 kbps down to 1200 bps

Note: The modem is capable of receiving at up to 56 kbps and sending at up to

31.2 kbps. Because of FCC regulations, receiving speeds are limited to 53
kbps. The actual speed can vary, depending on factors such as current line
noise.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

40 Using Enterprise Edge Services

Backup WAN Links

Enterprise Edge supports Microsoft Point-to-Point Compression (MPPC), RFC
2118 for traffic across dial-up links. The compression ratio of MPPC is
approximately 4-5 to 1.

For the remote backup, Enterprise Edge supports the following authentication
mechanisms:

• Password Authentication Protocol (PAP)

• Challenge Handshake Authentication Protocol (CHAP) is a more secure
procedure for connecting to a system than the PAP. The system attempts CHAP
before using PAP.

Software data compression on backup/dial up link is an optional feature in
Enterprise Edge. The default is set to ENABLE data compression.

Note: Remote user dial in as a RAS client is supported for administrative purposes

only.

Guidelines for Using Remote Dial In

Consider the following guidelines when using remote dial in:

• The same modem is shared between the remote dial-in for administration and
the backup WAN link. If a remote administration user is connected while the
primary link breaks, the automatic backup function does not occur.

• While using back up interface, Enterprise Edge always calls. Enterprise Edge
does not answer an incoming call from a router.

• Support for callback configuration is not provided.

Configuring Unified Manager Settings 45

Status fields, where available, are the accumulation of 'administrative' and
'operational' status’ of the component queried.

The three administrative statuses that can be assumed by a component are:

• Enabled: the component is enabled to operate in its normal mode, with all
normal parameters set. When the component is enabled, the component can
assume any of its operational statuses.

• Disabled: the component is disabled from operation. None of the component’s
operational statuses are valid in this state.

• Paused: the component is enabled and is running but is currently not accepting
additional service requests.

The two operational statuses that can be assumed by a component are:

• Up: the component is up and running normally

• Down: the component is down, due to some reason - normal or abnormal,
internal or external.

The Status column supports the combined list of these statuses:

• Up: This value is read-only. It indicates that the component is enabled and is
operating normally. For a component like a network interface, this means the
interface is enabled and connected to a valid link. For a service like DHCP, it
means that the service is enabled and is running normally.

• When the current status is 'Up', setting it to 'Enabled' or 'Continue' where
available, is a no-operation. Setting it to 'Disabled' disables the service, by
shutting it down and then disabling it. Where available, setting it to 'Paused'
pauses the service.

• Down: This value is read-only. This value indicates that the user has enabled the
component, and the component is unable to operate in an 'Up' state because of
normal or abnormal, internal or external errors. For example, if a network
interface is not in an 'Up' state because of no connection to an actual physical
link, it is a normal, external error. If a service like DHCP service is not in an 'Up'
state because of internal errors, it is an abnormal, internal error.

• When the current status is 'Down' setting it to 'Enabled' attempts to bring it to
'Up' state again. As a result it may stay at a 'Down' state. Setting it to 'Disabled'
disables the service. Where available, setting it to a 'Paused' or continued state
fail as the service is not yet running.

• Enabled: This value is write-only. This value never appears when read. For a
service that is enabled, one of its operational statuses (that is, Up or Down)
appears when its Status field is read.

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

46 Configuring Unified Manager Settings

• When this value is set, it indicates that the user wants to enable the
corresponding component and bring it to an 'Up' state. It is probable that the first
happens. The second action depends on the component. For a network interface,
the 'Up' state does not happen unless user connects a link to the interface. For a
service this may not happen only if the system encounters an error of some kind
during the requested action.

• Disabled: This value can be either read or set. When read, this indi cates that the
component is disabled from operation. When set, it indicates the same, in
addition to taking the component to a 'Down' state before disabling.

• Paused: This value can be either read or set. When read, this indicates that the
service is enabled and is given the command to pause. When set, it indicates the
same, pausing the service further.

• Continue: This value can only be set. It can be set only when the service in a
Paused state. It resumes paused service.

Setting Definition

Connection Type Lets users specify the connection type to the LAN interface.

The following values are supported and are interpreted as follows:

Auto Sense: The interface uses 'auto negotiation' protocol to choose the

maximum possible speed of the connection. Depending upon the connected

device, the interface can choose '100 MB' or '10MB', full-duplex, or half-

duplex.

The receiving end’s speed and connection type determines the mode of

transmission. For example, if the receiving end is another PC port, or a

bridge/switch port, the full duplex of operation is possible; if the receiving

end is a shared media port (like hub port), only half-duplex of mode is

possible.

10 MB Half: Speed is set to 10 MB/s and mode to half-duplex.

10 MB Full: Speed is set to 10 MB/s and mode to full-duplex

10 MB Auto: The speed is set to 10 MB/s and the mode is automatically

chosen by the interface, using auto-negotiation protocol. This mode is

chosen to limit the maximum traffic coming in to Enterprise Edge to 10 MB,

while enabling the auto-negotiation feature for easier interconnection.

Usually, you limit the incoming traffic if you notice that the bursty traffic

from the connected LAN is degrading the quality of voice calls carried

through VoIP over WAN. Though the LAN traffic gets lower priority in

Enterprise Edge, their high rate of arrival to the Enterprise Edge server

generates too may interrupts in the system that cause degraded quality in

voice calls carried as VoIP.

100 MB Half: Speed is set to 100 MB/s and mode to half-duplex 100 MB

Full: Speed is set to 100 MB/s and mode to full-duplex.
Status Lets users view the current status of the LAN interface.

The possible states are:

Up: the resource is operational.

Down: the resource is not operational.

WAN Primary Link Line Parameters

The WAN Link Line Parameters settings are:

Setting Definition

Channel Rate Lets users set the data rate for each of the DS0 channels in the T1 line.
Clock Source Lets users set an internal or external T1 clock source.
Frame Type Lets users set the type of framing to be adopted in the T1 line.

You can select either SF(D4) or ESF for frame type. SF(D4) transmits
superframes consisting of 12 individual frames. ESF transmits superframes
consisting of 24 individual D4 frames and provides enhanced signaling and
synchronization.

ESF lets you testing the digital line while it is in use.
Always use the frame type that the equipment at the receiving end expects.

Line Coding Lets users set the type of encoding used in the T1 line.

You can select either B8ZS or AMI for this parameter. B8ZS (Bipolar with 8
Zero Substitution) line coding replaces a block of eight consecutive binary zeros
with an 8-bit B8ZS code containing bipolar violations in the fourth and seventh
bit positions of the substituted code. In the receiving direction, the B8ZS code is
detected and replaced with eight consecutive binary zeros.

AMI line coding is also bipolar: a binary zero is transmitted as zero volts, and a
binary 1 is transmitted as either a positive or negative pulse, opposite in polarity
to the previous pulse.

Always use the line coding method that the equipment at the receiving end
expects.

Line Polarity Lets users set normal or inverted line polarity in the T1 line. The option inverted

is meaningful only if LineCoding is AMI.

Pulse Density Lets users control whether the DSU/CSU maintains the minimum level of 1s on

the line for AMI encoding.

Channel List Lets users create a list of channels used in the T1 line.

You can specify multiple channel numbers in a comma-separated list. Each item
in the list can contain a range of channel numbers, with the limits of the range
separated by a hyphen character. For example, this is a valid value for channel
list: 3,5,6,10-15,18,20-23. If you use all of the channels, specify it by using the

WAN Primary Link Frame Relay Parameters

The WAN Frame Relay Parameters are:.

Setting Definition

LMI Type Lets users set the type of link management protocol used on this link.

This value must match the corresponding value set in the Frame Relay
service provider’s switch. Permitted values are ANSI, LMI, and
CCITT. The default setting is ANSI.

Polling Interval Lets users set a value, in seconds, as an interval between LMI status

inquiry messages. This v alue must match the corr espondi ng value set in
the Frame Relay provider’s switch. Permitted values are between 5-30
(in seconds). The default setting is 10.

Full Enquiry Interval Lets users set the maximum number of LMI Status Enquiry messages

sent before sending a Full Status Enquiry request. This value must
match the corresponding value set in the Frame Relay provider’s
switch. Permitted values are between 1 and 255 (in seconds). The
default setting is 6.

Error Threshold Lets users set the maximum number of consecutive failures permitted

in LMI Status Enquiry before marking the link non-operational. It is
also the number of successful consecutive LMI Status Enquiry
messages that must be received before marking a link as operational.
Permitted values are between 0 and MAXINT. The default setting is 3.

Monitored Events Lets users s et the number of even ts sampled for making decis ions about

the error threshold. Set the number higher than the values set in the
error threshold. Permitted values are a number between 0 and
MAXINT. The default setting is 4.

DS Code Lets users set the differentiated services code (DSCode) recognized by

the frame relay driver for prioritization. This value is used as a mask
value. When an IP packet is sent down, the frame-relay driver checks if
the packet's DSCode field (known as TOS byte in earlier documents)
has any of the bits specified in this field set (a bitwise AND operation is
performed between this field's value and the DSCode field of the IP
packet and the result is checked for 0). If any of the bits is set (result is
non-zero), the frame relay network is signaled to handle this packet
with priority by clearing the 'D/E' (discard eligibility) bit in the frame
relay packet header. If none of the bits specified in this field are set in
the IP packet header, 'D/E' bit is set in the frame-relay packet header,
marking the packet as a likely candidate for packet drop in case of
congestion in the frame relay network.

This field's value carries the same semantics as the 'differentiated
services codepoint' discussed in RFC2474. The least significant two
bits are ignored.

Compression Enabled
PVCs

Lists PVCs on which compression is enabled. If the compression field
is Disabled, the field does not have any meaning. If the compression
level Enabled, compression and decompression are performed on the
data going to and coming from the PVCs in this list.

The value can be a comma-separated list of DLCI numbers. You can
specify a range of DLCIs b y specify ing th e lower and u pper bound aries
by a hyphen. You can mix individual numbers and ranges.

Note: If the IP Address or subnet mask for a LAN interface is changed, the

corresponding DHCP scope is created or modified for the interface.
This operation also involves setting default values for some
parameters. By default, Enterprise Edge sets the IP Address of
corresponding LAN interface to DNS Server, WINS Server, Default
Gateway options of the scope. It also sets the lease time to 3 days,
creates a range of addresses for the scope. If the IP Address of the
LAN interface is in the lower half of the subnet, the address range set
for the scope includes all the address above the LAN interface address.
If the IP Address of the LAN interface is in the upper half of the
