Linux IPef UDP Test Find Latency Question


I have some network and linux test experience so I have been asked to help conduct some network tests on company products. Essentially, I have 2 linux laptops that are connected "ethernet bridged" with the network device under test and I have been using Iperf as the main test tool using its UDP payload.

In this environment UDP reports on jitter, packet loss, throughput and payload size. However, I have been just asked to try to find latency also. The problem I have is I did not originally test for latency and for data all I have is what Iperf reports by default and I did script up a program using netsniff-ng which takes 15 second pcap samples on the receiver laptop. The problem continues because they took the devices away from me so I cannot simply just re-test I only have the pcap file and Iper log file to work with.

My question is using the pcap file which contains only UDP Iperf data is there a way to get some idea of the network latency? I also took a couple tests using video traffic which goes over TCP, so I am guessing I should be able to get latency that way at least?

Thanks for any comments or advice,

Iperf report could include latency.
