The
D-FRAP is a Frame Relay Access Probe with an integral
56/64 Kbps DSU/CSU. Designed for use as a single monitoring
unit or for wide scale deployment in WAN networks, the
D-FRAP collects and stores frame relay performance information
and data about the utilization of application protocols.
The D-FRAP monitors and stores tabular
data about the performance of up to 16 Data Link Connection
Identifiers (DLCIs). It provides information on the utilization,
availability and round trip delay of each PVC. The D-FRAP
also provides a Committed Information Rate (CIR) report.
Network data can be stored for up to four days to aid
in troubleshooting and minimize polling. All reports
can be accessed via SNMP or viewed in table form locally
or via Telnet. The D-FRAP can also be used with Envisage™,
an NT / UNIX / JAVA based GUI application that simplifies
use and displays graphical results of collected data
for quick and easy interpretation.
FEATURES
- Frame Relay Access Probe TM (FRAP) with built-in
56/64 Kbps DSU/CSU
- Collects statistical information on frame relay environments,
including all RFC 1315 variables such as FECNs, BECNs,
DE, Frame Errors, packets transmitted/received and
more
- V.35 M-Block, front panel LCD & keypad
- Collection can be set by the user for independent
short-term (3 to 15 second) and long-term (4 seconds
to 60 minute) periods
- QoS monitoring for Service Level Agreement (SLA)
verification including round trip delay, availability
and utilization percentage per PVC and per-DLCI availability
- TFTP software downloadable over the network
- Supports Sync Virtual Network Interface Protocol
(VNIP) capability for automatic topology mapping, congestion
monitoring and per PVC loopbacks and diagnostics
- Monitors the performance of application
APPLICATIONS
The D-FRAP can be used at 56 and 64 Kbps to provide
frame relay or other digital access for routers and Frame
Relay Access Devices (FRADs), monitors traffic and provides
statistics on the frame relay network.
BENEFITS
Advanced In-Band Management
The D-FRAP utilizes a unique in-band
management technique that eliminates the need for additional
management cabling and enables the D-FRAP to be accessed
regardless of the type of router used. The D-FRAP also
sources ("spoofs")
LMI, allowing the D-FRAP to keep management DLCIs active
should the network or router fail. This provides additional
access visibility for troubleshooting even if the router
fails or is not present.
VNIP Provides Troubleshooting Tools for Virtual
Networks
The Virtual Network Interactive Protocol
(VNIP) is a technique that enables network operators
to gain visibility of their virtual network to ease
troubleshooting and network planning and to ensure
Quality of Service (QoS). While virtual topologies,
such as frame relay, result in significant cost savings,
many of the traditional, point-to-point network troubleshooting
tools are not available. VNIP architecture gives D-FRAP
users visibility into the network "cloud" to
automatically discover end-points and provide other
valuable information, such as network latency/delay
measurements, logical per PVC loopbacks, automatic
topology maps, congestion monitoring and more.
Trend Analysis and Circuit Management
The
D-FRAP can be used as an independent frame relay monitor
or in conjunction with the Envisage Network
Management product, a real time "point-and-click" graphical
user interface (GUI).
Envisage manages the D-FRAP as well
as VITAL ’s
other circuit management and FRAD products. Envisage
works under Windows/NT in addition to UNIX and provides
a Java web-based interface and access.
