displays the
Packet Jitter
results;
Packet Jitter displayed in milliseconds.
Current is the current jitter value
Max is the maximum jitter value
Note: Packet Jitter
This measurement is based on the data packet inter-arrival time which is a measure of packet arrival
variance. Packet jitter affects packet arrival throughout the network. Variations lead to buffer under /
overflows at the receiving equipment e.g. STB. Jitter impacts the way packets are handled at various net
work elements i.e. If the jitter is too high, packet loss will increase as queuing software tries to load balance
traffic at network elements. Packet jitter should not be confused with PCR jitter (described below). When
Packet jitter is present, the cause is normally related to the Ethernet physical layer. When PCR jitter is
present, then the cause is most likely related to the program flow and could be related to an encoder not
performing to specification.
