[Ethereal-users] Question about Tools->Summary in Ethereal

[Tao Lin <taolin@xxxxxx>]

I am using Ethereal 0.8.18 version to capture traffic in a LAN.

 

The traffic is TCP/IP traffic and the ethernet frame size is set to 590 bytes. The transmission rate is 600,000bps. So the interval time for 590 bytes should be 0.00786667 second.

 

In Ethereal capture results, most of those interval times I got are less than 0.00786667 second, but the Tools->Summary shows that the average transmission speed is lower than 600,000 bps. Can anyone tell me how Ethereal calculates the transmission speed? Thanks!

 

BTW: Please reply to my email box.

 

Have a good day!
