Wireshark · Ethereal-users: [Ethereal-users] Analysis - Previous Segment Lost

["jon.johnston" <jon.johnston@xxxxxxxxx>]

I realize that Ethernet inherently includes some level of loss. However, 
I am seeing what appears to be a large number of "previous segment lost" 
packets, and I am concerned about how to measure the number of 
re-transmitted packets with regards to overall traffic.

I assume I could write a filter, or something that would specifically 
show the number of re-transmitted packets....which I would think would 
involve counting the TCP sequence numbers by session. Is that possible 
in Ethereal?

Any ideas are certainly welcome, I am pretty much a noob at this level 
of Ethereal. Thank you.
