delay in TCP

0

Hi!!

I am new to wireshark and I am trying to plot and measure the delay of an end to end tcp packet, that is, I would like to find out how long it takes a tcp packet transmitted from a node to be received from the another node.

Thanks!!!

If you captured only on one side (client, server or somewhere between), you can't really measure that time exactly, however you can estimate it by looking at the SYN,SYN-ACK,ACK sequence (look at the time difference of these three packets) and the mean RTT of other SEQ/ACK 'sequences'.

If you want to get a general overview of all packets in a TCP connection (not just a certain packet), you can draw a TCP Stream Graph

Statistics -> TCP Stream Graph -> Round Trip Time Graph
