Hi all, is there a way of mapping out latency from a CSV output exported from Wireshark?

Trying to determine system latency using Wireshark and the CSV output that they have provided. Only output I have is: '443 > 64307 [ACK] Seq=6681 Ack=97266 Win=8224 Len=1336 [TCP segment of a reassembled PDU]' and "No. Time Source Destination Protocol Bits Length" Can anyone guide me in the right direction? Thanks in advance.

Hi,

The best way to do this is with the original packet capture file inside Wireshark.

Wireshark will do a lot of the heavy lifting for you.

If you just have a CSV file with the default columns then you can try to calculate what time has passed between interesting packets like TCP 3-way handshake (SYN, SYN/ACK, ACK) for frames to/from the same TCP ports but you are not going to be 100% sure of your answer because you don't know what the settings were in Wireshark when the CSV was created.

And that is assuming it was generated from Wireshark to begin with: File --> Export Packet Dissections --> As CSV...

Hope this helps.

Cheers,

JFD
