One recent capture had 300 total retransmissions for one user, but the number of frames for this user was 21.531, for a rate of 1.39%.  Do I ignore this as a normal occurrence?.
 
=> Alok: What do you meanby "rate" here?
====>Gunndo: Total number of retransmitted frames for a given LAN IP divided by total number of TCP frames for a given LAN IP.  Make the example read 300/21531, not 300/21.531.
=>Alok: Out here in India I have seen these numbers on something as simple as bridged ethernet LAN too... so I really dont know why they happen, but I do know that they do.  i think 1% is high if you say 1 out of every 10 TCP frames needs a retransmission.
errrrr!==> 1 /100 ;-)
