6.16 Configuring the LSP Jitter Test
This section describes how to configure an LSP jitter test to measure jitter in the LSP during the
packet transmission.
6.16.1 Establishing the Configuration Task
Before configuring an LSP jitter test, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task quickly and accurately.
Applicable Environment
The NQA LSP Jitter test is performed to check the reachability of static LSP and LDP LSP.
After receiving a packet from the source, the destination calculates the maximum, minimum,
and average jitter time of the packet transmitted from the source to the destination. This clearly
reflects the status of the MPLS network.
NOTE
LSP Jitter tests do not support load balancing.
