Hallo,

I've been using tcptrace to analyze captures. The capturfiles was build with tcpdump and following options -i eth3 –w tcpdump.dmp. I will see all tcp traffic over eth3. I analyze the capturefile with tcptrace –xtraffic” –i1 –B”. The result is:

Overall Statistics over 599 seconds (0:09:59.865769):
808647244 ttl bytes sent, 1349995.379 bytes/second
753195171 ttl non-rexmit bytes sent, 1257421.035 bytes/second
55452073 ttl rexmit bytes sent, 92574.411 bytes/second
2520750 packets sent, 4208.264 packets/second
1053 connections opened, 1.758 conns/second
12167 dupacks sent, 20.312 dupacks/second
70228 rexmits sent, 117.242 rexmits/second
average RTT: 112.957 msecs

What is non-rexmit bytes and what is rexmit bytes?
Is it a pices from bytes send?
I have load the traffic_byport in excel. I create the sum off bytes overall ports, the resault is:
1617294488

Is it the same as 808647244+808647244+55452073?
The total bytes in the traffic_byport is 808647244.
What is the total traffic over the interface? Can you help me?

Mit freundlichen Grüßen aus Dresden.
With kind regards from Dresden in Germany.
