The following program, mtr, seems very appropriate:

Also note the following from the man page for tcpdump:

-tt Print an unformatted timestamp on each dump line.

-ttt Print a delta (in micro-seconds) between current and previous
line on each dump line.

From http://node1.yo-linux.com/cgi-bin/ma...ommand=tcpdump

It seems to me that you could easily write a script to make use of this.

Hope this helps get you started.
