DATA SHEET
IxNetwork TM RSVP-TE Emulation
Software
Ixia's IxNetwork RSVP-TE (Resource reSerVation Protocol with Traffic
Engineering) Emulation Software is designed to analyze the performance of
MPLS Label Edge Routers (LERs) and Label Switching Routers (LSRs).
When used in conjunction with an Interior Gateway Protocol (IGP) with traffic
engineering extensions, such as OSPF-TE or IS-IS-TE, large and complex
MPLS topologies can be emulated.
Ixia's RSVP-TE Emulation Software can be easily configured to establish and
maintain thousands of Label Switched Paths (LSPs) on each Ixia test port to
stress the most powerful MPLS-capable routers. Once LSPs are generated,
MPLS traffic can be transmitted, at line-rate speed, to capture metrics such
as packet loss and forwarding rates. RSVP Fast Re-route is supported to test
systems for traffic re-direction upon failures.
Key Features
• Simultaneously emulate an
ingress and egress router on
the same test port to
establish bi-directional pairs
of tunnels
• Set up large, complex
topologies quickly and easily
with the RSVP-TE wizard
• Configure large numbers of
entries quickly with
spreadsheet entry mode
• Modify configuration entries
while the state machine is
running to simulate realistic
network conditions
• Customize by configuring
detailed object parameters
• View labels assigned and
received as well as LSP
statistics
• Generate wire-speed MPLS
data plane traffic
automatically with Traffic
Wizard
• Update MPLS traffic
dynamically, without having
to stop and restart traffic
• Create Tcl configuration
code simply by using
ScriptGen
• Analyze and track real-time
MPLS traffic on a per-flow
basis

Emulation Flexibility
Ixia's RSVP-TE Emulation Software has the flexibility
to emulate one or more ingress and egress routers
and generate thousands of LSPs on a single port.
Many session and tunnel attributes are exposed,
enabling users to create customized configurations.
Users also have the flexibility to configure via Tcl
commands. Protocol window configurations can be
easily converted to Tcl commands with Ixia's
ScriptGen utility.
Scalability
Hundreds of thousands of LSPs can be supported on
an IXIA chassis populated with per port CPU Load
Modules. Multiple protocols can be run simultaneously
in conjunction with line-rate traffic. In addition,
sessions and tunnels can be flapped to dynamically to
assess how an MPLS router will behave under
adverse network conditions.
Dynamic MPLS Labels
If MPLS label values are modified via LDP protocol updates, IxNetwork will automatically update MPLS traffic
packets with the latest label values. User are no longer required to stop and restart the traffic engine to obtain the
most recently exchanged MPLS label values. This feature greatly improves test realism and effectiveness,
ensuring that traffic can remain running at all times during testing.
Multi-Protocol Support
Multiple protocols from Ixia's family of emulation software can be run simultaneously on one or many ports to
simulate realistic network scenarios. Generate line rate MPLS traffic to advertised labels. Learn when routers
transmit traffic to MPLS labels instead of routes in the forwarding information base. Multiple protocols from Ixia's
family of emulation software can be run simultaneously on one or many ports to simulate realistic network
scenarios.
Easy-to-Use Interface
The IxNetwork GUI facilitates the quick and easy configuration of routing protocol emulations. Configuration
wizards provide a graphical-based, step-by-step process for initial setup of small to large scale test topologies
across multiple Ixia test ports. The RSVP-TE wizard significantly simplifies the setup of tunnels in complex RSVP-
TE scenarios. In addition, IxNetwork's spreadsheet GUI paradigm provides for the entry, editing, and viewing of
large configurations across multiple test ports. Spreadsheet-like commands are available to quickly scale a
configuration or apply operations across multiple values. Once a network topology is created, it can be copied
easily across any supported Ixia test port.
Tcl Support
Automated scripts can be quickly created using the Tcl scripting environment. Alternatively, the IxNetwork GUI
can be used to set up a test configuration, then Ixia's ScriptGen utility used to translate the GUI settings to Tcl
code with minimal commands. Tcl support is available on Windows, Linux, and UNIX platforms.
