The central site FrameSaver unit ordinarily is configured for management from a Network Management System (NMS), through either the attached router, as shown in the above figure, or through the Network Operations Center (NOC) router (for management by the Network Service Provider). Multiple management PVCs then connect the central site unit to the remote site units using Paradyne’s proprietary PVC multiplexing method (embedded DLCIs).

About FrameSaver SLV In-Line Monitors

FrameSaver SLV In-Line Monitor Features

The FrameSaver SLV in-line monitor provides the following features:
H Intelligent Service Level Verification. Provides accurate throughput,
latency, and availability measurements to determine network performance and whether service level agreements (SLAs) are being met, along with SLA reporting. SLA parameter thresholds can be configured to provide proactive notification of a developing network problem.
H Security. Provides multiple levels of security to prevent unauthorized access
to the unit.
H TruePutt Technology. Using Frame Delivery Ratios (FDR) and Data
Delivery Ratios (DDR), throughput (within and above CIR, as well as between CIR and EIR, and above EIR) can be measured precisely, eliminating inaccuracies due to averaging. These ratios are available through OpenLane SLV reports.
H Frame Relay Aware Management. Supports diagnostic and network
management features over the frame relay network using the Annex-A, Annex-D, and Standard UNI (User Network Interface) LMI management protocol. The unit’s frame relay capability also supports:
— Inband management channels over the frame relay network using
dedicated PVCs. — Unique nondisruptive diagnostics. — CIR monitoring on a PVC basis. — Multiple PVCs on an interface. — Multiplexing management PVCs with user data PVCs. — Multiplexing multiple PVCs going to the same location onto a single
network PVC.
H Auto-Configuration. Provides the following automatic configuration features:
— Frame Relay Discovery – For automatic discovery of network DLCIs and
configuration of a user data port DLCI, the PVC connection, and a
management PVC, which is multiplexed with user data DLCIs. — LMI Protocol Discovery – For automatic configuration of the protocol
being used by the network. — DLCI Deletion – For automatic removal of configuration of unused DLCIs
from the unit’s configuration and statistical databases. — CIR Determination – For automatic recalculation of the committed rate
measurement interval (Tc) and excess burst size (Be) when a DLCI’s CIR
changes.
Excess burst size (Be) and committed burst size (Bc) are recalculated
when Committed Burst Size Bc (Bits) is set to CIR. The committed rate
measurement interval (Tc) is recalculated when Committed Burst Size Bc
(Bits) is set to Other.

About FrameSaver SLV In-Line Monitors
H RMON-Based User History Statistics Gathering. Provides everything
needed to monitor network service levels, plus throughput with accurate data delivery, network latency, and LMI and PVC availability.
In addition, port bursting statistics are kept for all frame relay links. These statistics are available real-time via the Enterprise MIB and historically as an RMON2 User History object. In future releases of the OpenLane SLM system, this will enable even more accurate calculations of utilization.
H Network User History Synchronization. Allows correlation of RMON2 User
History statistics among all SLV devices in a network for more accurate OpenLane SLV reports. Using a central clock, called the network reference time, all SLV device user history statistics are synchronized across the network, further enhancing the accuracy of OpenLane SLV reports.
H Extensive Testing Capability. Provides a variety of tests to identify
and diagnose device, network, and other problems. These tests can be commanded from the unit’s menu-driven user interface or the OpenLane system (using its easy-to-use Diagnostic Troubleshooting feature).
H Dedicated Troubleshooting PVC. Provides a troubleshooting management
link that helps service providers isolate problems within their network. This feature can be configured from the menu-driven user interface.
H Maximum Number of PVCs and Management PVCs Supported.

H Router-Independence. Unique diagnostics, performance monitoring,
PVC-based in-band network management, and SNMP connectivity is not dependent upon external routers, cables, or LAN adapters.
H Inverse ARP and Standard RIP Support. Provides Inverse ARP (Address
Resolution Protocol) support so the frame relay router at one end of a management PVC can acquire the IP address of a FrameSaver unit at the other end of the PVC. Standard RIP (Routing Information Protocol) allows the router to automatically learn the routes to all FrameSaver units connected to that FrameSaver unit.
H LMI Packet Capture. Provides a way to upload data that has been captured
in a trace file so the data can be uploaded and transferred to a Network Associates Sniffer for analysis, or viewed via the menu-driven user interface. The 12 most recent LMI messages can be displayed from the menu-driven user interface.

About FrameSaver SLV In-Line Monitors
H ATM VPI/VCI and DLCI Correlation. For networks with both ATM and frame
relay-access endpoints, allows the FrameSaver unit to report the originating Virtual Path or Channel Identifier (VPI/VCI) in the far-end ATM-access endpoint where the local DLCI is mapped so they can be correlated for OpenLane SLV reports.
H Back-to-Back Operation. Allows two FrameSaver devices to be connected
via a leased-line network or simulation so a point-to-point configuration can be implemented.
H Configuration Upload/Download and Software Download Capability.
Provides quick transfer of configuration options to and from nodes and software downloads while the unit is running using the standard File Transfer Protocol (FTP). Two software images can be stored.
H Dual Flash Memory. Allows software upgrades while the unit is up and
running. Two software loads can be stored and implemented at the user’s discretion.
H OpenLane Service Level Management Solution. Provides an
advanced, standards-based performance monitoring and management application.
Being standards-based, the OpenLane SLM system can also be used with other management applications like HP OpenView or IBM’s NetV iew. OpenLane includes HP OpenView adapters for integrating OpenLane features with the OpenView Web interface.
Being Web-based, the OpenLane system provides Web access to the data contained in the database to provide anytime, anywhere access to this information via a Web browser.
Some of the OpenLane SLM system’s features include:
— Real-time performance graphs provide exact performance measurement
details (not averages, which can skew performance results) of service
level agreement (SLA) parameters. — Historical SLV graphs provide service level management historical
reports so frame relay SLAs can be verified. — Diagnostic troubleshooting provides an easy-to-use tool for performing
tests, which include end-to-end, PVC loopback, connectivity, and physical
interface tests. — Basic configuration allows you to configure FrameSaver devices, and set
RMON alarms and thresholds. Network DLCI Circuit IDs can also be
assigned. — Automatic SLV device and PVC discovery allows all SLV devices with
their SLV Delivery Ratio configuration option enabled to be discovered
automatically, along with their PVCs. — A FrameSaver unit can be reset from the OpenLane system. — Firmware downloading provides an easy-to-use tool for downloading to
an entire network or a portion of the network. — On-demand polling of FrameSaver devices, and SNMP polling and
reporting are available.

About FrameSaver SLV In-Line Monitors
H NetScout Manager Plus and NetScout Probe Support. Provides complete
LAN and WAN traffic analysis and monitoring functions for FrameSaver SLV devices. The following features are supported using this application:
— Thresholds for RMON 1 (Remote Monitoring, Version 1) alarms and
events can be configured. — (Models 9820 and 9820-2M.) Performance monitoring can be performed
using collected RMON 2 (Version 2) data. NetScout Manager Plus’s
Protocol Directory and Distribution functionality allows FrameSaver SLV
9820 and 9820-2M units to measure up to eleven network-layer protocols
and report the amount of traffic generated by each. Its IP Top Talkers and
Listeners reporting identifies the devices using network bandwidth for
traffic and protocol analysis, identifying the network’s top six users. In
addition, it collects performance statistics from FrameSaver devices. Up
to 900 samples can be stored in 15-minute buckets, with 96 buckets in a
24-hour period, for up to five days worth of data. — Optional standalone NetScout Probes can be used with FrameSaver
devices at sites where full 7-layer monitoring, an unlimited number of
protocols, and advanced frame capture and decode capabilities are
desired.
