The ICMP jitter test uses ICMP packets to determine the delay, jitter, and packet loss ratio based on the timestamps in test packets. Jitter is the interval for receiving two consecutive packets minus the interval for sending the two packets.
The ICMP jitter test process is as follows:
The source (SwitchA) sends packets to the destination (SwitchB) at a specified interval.
The destination receives the packets, adds a timestamp to them, and sends them back to the source.
The source receives the packets and calculates the jitter by subtracting the interval at which consecutive packets are sent from the interval at which the destination receives them.
The maximum, minimum, and average jitter of the packets from the source to the destination and from the destination to the source.
The maximum unidirectional delay from the source to the destination or from the destination to the source.
In an ICMP jitter test, the interval for sending packets is configurable and defaults to 20 ms. The number of packets sent each time is configurable and defaults to 60.
You can set the number of consecutive packets to be sent in a single test instance. This allows you to simulate actual data traffic for a specified period of time.
ICMP jitter test results and historical records are collected in test instances. You can run commands to view the test results and historical records.
