tcptrace a TCP dump file analysis tool written by Shawn Ostermann
|
|
at Ohio University. It is NOT a packet capture program. It reads
|
|
output dump files in the formats of several popular packet capturing
|
|
programs: tcpdump, snoop, etherpeek, and netm. It can also output
|
|
(ie, convert thus converting to) tcpdump format files.
|
|
|
|
For each connection, it keeps track of elapsed time, bytes/segments
|
|
sent and received, retransmissions, round trip times, window
|
|
advertisements, throughput, etc. Its output format ranges from
|
|
Simple to Long to Very Detailed.
|
|
|
|
It can also produce three different types of graphs, as follows:
|
|
|
|
Time Sequence Graph
|
|
This is the format that Tim Shepard started using at MIT some
|
|
years ago. It shows segments sent and ACKs returned as a
|
|
function of time.
|
|
Instantaneous Throughput
|
|
This format shows the instantaneous (averaged over a few
|
|
segments) throughput of the connection as a function of time.
|
|
Round Trip Times
|
|
This format shows the round trip times for the ACKs as a
|
|
function of time.
|
|
|
|
The graphs produced are viewable only by Tim Shepard's wonderful
|
|
xplot program (in math/xplot).
