Test Case: Switch Flow Failover Performance Test
Test Case: Switch Flow Failover Performance Test
Overview
Networking infrastructure has become key component for any business. Today’s
networks carries Voice, Data and Video traffic over the same network infrastructure.
Even the few seconds outage can cause huge impact on the business. Therefore
networks are designed with redundant links to minimize the downtime and increase the
reliability. The key challenge for any networking device is to be able to detect the
failure and forward traffic to redundant path without affecting application traffic
performance.
Objective
The objective of this test case is to verify Switch performance to handle convergence in
the network and ability to converge the traffic to secondary path without affecting
traffic forwarding performance. For this test, Ixia’s unique TrueView convergence test
methodology will be used to measure the data plane to data plane convergence time
of the switch.
TrueView convergence test provides the following measurements:
• Timestamp of every packet
• Timestamp the first packet in and last packet out on a port per flow
• Ability to capture protocol event timestamp
• Ability to capture link event timestamp
• Ability to monitor receive rate and timestamp when "Below" thresholds are crossed
• Ability to monitor receive rate and timestamp when "Above" thresholds are crossed
• Ability to timestamp link event (up/down)
