CHAPTER 16
Media Bandwidth Management
Advanced Setup
This chapter describes bandwidth management with one level of child class.
16.1 Media Bandwidth Management Overview
Bandwidth management allows you to allocate an interface’s outgoing capacity to specific
types of traffic. It can also help you make sure that the Prestige forwards certain types of
traffic (especially real-time applications) with minimum delay. With the use of real-time
applications such as Voice-over-IP (VoIP) increasing, the requirement for bandwidth
allocation is also increasing.
Bandwidth management addresses questions such as:
• Who gets how much access to specific applications?
• What priority level should you give to each type of traffic?
• Which traffic must have guaranteed delivery?
• How much bandwidth should be allotted to guarantee delivery?
Bandwidth management also allows you to configure the allowed output for an interface to
match what the network can handle. This helps reduce delays and dropped packets at the next
routing device. For example, you can set the WAN interface speed to 1000kbps if the ADSL
connection has an upstream speed of 1Mbps. All configuration screens display measurements
in kbps (kilobits per second), but this User’s Guide also uses Mbps (megabits per second) for
brevity’s sake.
Refer to Section 16.9 on page 188 to enable and configure bandwidth on the interfaces.
Refer to Section 16.10 on page 190 to configure bandwidth classes.
Refer to Section 16.11 on page 194 to view bandwidth usage information.
16.2 Bandwidth Classes and Filters
Use bandwidth classes and child-classes to allocate specific amounts of bandwidth capacity
(bandwidth budgets). Configure a bandwidth filter to define a bandwidth class (or child-class)
based on a specific application and/or subnet. Use the Class Configuration screen (see
Section 16.10 on page 190) to set up a bandwidth class’s name, bandwidth allotment, and
Chapter 16 Media Bandwidth Management Advanced Setup 182
P-660H/HW/W-T Series User’ Guide
bandwidth filter. You can configure up to one bandwidth filter per bandwidth class. You can
also configure bandwidth classes without bandwidth filters. However, it is recommended that
you configure child-classes with filters for any classes that you configure without filters. The
Prestige leaves the bandwidth budget allocated and unused for a class that does not have a
filter itself or child-classes with filters. View your configured bandwidth classes and childclasses in the Class Setup screen (see Section 16.10 on page 190 for details).
The total of the configured bandwidth budgets for child-classes cannot exceed the configured
bandwidth budget speed of the parent class.
16.3 Proportional Bandwidth Allocation
Bandwidth management allows you to define how much bandwidth each class gets; however,
the actual bandwidth allotted to each class decreases or increases in proportion to actual
available bandwidth.
16.4 Bandwidth Management Usage Examples
These examples show bandwidth management allotments on a WAN interface that is
configured for 640Kbps.
16.4.1 Application-based Bandwidth Management Example
The bandwidth classes in the following example are based solely on application. Each
bandwidth class (VoIP, Web, FTP, E-mail and Video) is allotted 128kbps.
Figure 87 Application-based Bandwidth Management Example
16.4.2 Subnet-based Bandwidth Management Example
The following example uses bandwidth classes based solely on LAN subnets. Each bandwidth
class (Subnet A and Subnet B) is allotted 320kbps.

Chapter 16 Media Bandwidth Management Advanced Setup 184
P-660H/HW/W-T Series User’ Guide
16.5 Scheduler
The scheduler divides up an interface’s bandwidth among the bandwidth classes. The Prestige
has two types of scheduler: fairness-based and priority-based.
16.5.1 Priority-based Scheduler
With the priority-based scheduler, the Prestige forwards traffic from bandwidth classes
according to the priorities that you assign to the bandwidth classes. The larger a bandwidth
class’s priority number is, the higher the priority. Assign real-time applications (like those
using audio or video) a higher priority number to provide smoother operation.
16.5.2 Fairness-based Scheduler
The Prestige divides bandwidth equally among bandwidth classes when using the fairnessbased scheduler; thus preventing one bandwidth class from using all of the interface’s
bandwidth.
16.6 Maximize Bandwidth Usage
The maximize bandwidth usage option (see Section 16.7.1 on page 187) allows the Prestige to
divide up any available bandwidth on the interface (including unallocated bandwidth and any
allocated bandwidth that a class is not using) among the bandwidth classes that require more
bandwidth.
When you enable maximize bandwidth usage, the Prestige first makes sure that each
bandwidth class gets up to its bandwidth allotment. Next, the Prestige divides up an interface’s
available bandwidth (bandwidth that is unbudgeted or unused by the classes) depending on
how many bandwidth classes require more bandwidth and on their priority levels. When only
one class requires more bandwidth, the Prestige gives extra bandwidth to that class.
When multiple classes require more bandwidth, the Prestige gives the highest priority classes
the available bandwidth first (as much as they require, if there is enough available bandwidth),
and then to lower priority classes if there is still bandwidth available. The Prestige distributes
the available bandwidth equally among classes with the same priority level.
16.6.1 Reserving Bandwidth for Non-Bandwidth Class Traffic
Do the following three steps to configure the Prestige to allow bandwidth for traffic that is not
defined in a bandwidth filter.
1 Leave some of the interface’s bandwidth unbudgeted.
2 Do not enable the interface’s Maximize Bandwidth Usage option.
3 Do not enable bandwidth borrowing on the child-classes that have the root class as their
parent (see Section 16.7 on page 187).
185 Chapter 16 Media Bandwidth Management Advanced Setup
16.6.2 Maximize Bandwidth Usage Example
Here is an example of a Prestige that has maximized bandwidth usage enabled on an interface.
The first figure shows each bandwidth class’s bandwidth budget and priority. The classes are
set up based on subnets. The interface is set to 10 Mbps. Each subnet is allocated 2 Mbps. The
unbudgeted 2 Mbps allows traffic not defined in one of the bandwidth filters to go out when
you do not select the maximize bandwidth option.
Figure 90 Bandwidth Allotment Example
P-660H/HW/W-T Series User’ Guide
The following figure shows the bandwidth usage with the maximize bandwidth usage option
enabled. The Prestige divides up the unbudgeted 2 Mbps among the classes that require more
bandwidth. If the administration department only uses 1 Mbps of the budgeted 2 Mbps, the
Prestige also divides the remaining 1 Mbps among the classes that require more bandwidth.
Therefore, the Prestige divides a total of 3 Mbps total of unbudgeted and unused bandwidth
among the classes that require more bandwidth.
In this case, suppose that all of the classes except for the administration class need more
bandwidth.
• Each class gets up to its budgeted bandwidth. The administration class only uses 1 Mbps
of its budgeted 2 Mbps.
• Sales and Marketing are first to get extra bandwidth because they have the highest
priority (6). If they each require 1.5 Mbps or more of extra bandwidth, the Prestige
divides the total 3 Mbps total of unbudgeted and unused bandwidth equally between the
sales and marketing departments (1.5 Mbps extra to each for a total of 3.5 Mbps for each)
because they both have the highest priority level.
• R&D requires more bandwidth but only gets its budgeted 2 Mbps because all of the
unbudgeted and unused bandwidth goes to the higher priority sales and marketing
classes.
• The Prestige does not send any traffic that is not defined in the bandwidth filters because
all of the unbudgeted bandwidth goes to the classes that need it.
Chapter 16 Media Bandwidth Management Advanced Setup 186
P-660H/HW/W-T Series User’ Guide
Figure 91 Maximize Bandwidth Usage Example
16.7 Bandwidth Borrowing
Bandwidth borrowing allows a child-class to borrow unused bandwidth from its parent class,
whereas maximize bandwidth usage allows bandwidth classes to borrow any unused or
unbudgeted bandwidth on the whole interface.
Enable bandwidth borrowing on a child-class to allow the child-class to use its parent class’s
unused bandwidth. A parent class’s unused bandwidth is given to the highest-priority childclass that has bandwidth borrowing configured, first.
The total of the bandwidth allotments for child-classes cannot exceed the bandwidth allotment
of their parent class. The Prestige uses the scheduler to divide a parent class’s unused
bandwidth among the child-classes.
16.7.1 Maximize Bandwidth Usage With Bandwidth Borrowing
If you configure both maximize bandwidth usage (on the interface) and bandwidth borrowing
(on individual child-classes), the Prestige functions as follows.
1 The Prestige sends traffic according to each bandwidth class’s bandwidth budget.
2 The Prestige assigns a parent class’s unused bandwidth to its child-classes that have more
traffic than their budgets and have bandwidth borrowing enabled. The Prestige gives
priority to bandwidth child-classes of higher priority and treats bandwidth classes of the
same priority equally.
3 The Prestige assigns any remaining unused or unbudgeted bandwidth on the interface to
any bandwidth class that requires it. The Prestige gives priority to bandwidth classes of
higher priority and treats bandwidth classes of the same level equally.
187 Chapter 16 Media Bandwidth Management Advanced Setup

4 The Prestige assigns any remaining unbudgeted bandwidth to traffic that does not match
any of the bandwidth classes.

17.3 DHCP Table Screen
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the Prestige
as a DHCP server or disable it. When configured as a server, the Prestige provides the TCP/IP
configuration for the clients. If set to None, DHCP service will be disabled and you must have
another DHCP server on your LAN, or else the computer must be manually configured.
Click Maintenance, and then the DHCP Table tab. Read-only information here relates to
your DHCP status. The DHCP table shows current DHCP Client information (including IP
Address, Host Name and MAC Address) of all network clients using the DHCP server.
