analysing snoop.tcl

[Ramesh Neelamani <neelsh@ruf.rice.edu>]

 Hello,

 We have run snoop.tcl (ns2.1) with various error rates (as directed in the 
 snoop.tcl file.

 For eg we have tried 
 ns snoop.tcl -e 0.2 -eu time -ll Snoop -r

 We tried changing the error rates (-e option) to various values but did 
 not find any significatn change in the output trace file. 

 In fact even removing the -ll Snoop option didn't seem to make much of a 
 difference.

 We are also unsure of what the 'r' in the beginning of the row of the 
 trace file means.

+ 0.001 2 0 tcp 1000 ------- 0 2.0
1.0 0 0 - 0.001 2 0 tcp 1000 ------- 0 2.0 1.0 0 0
r 0.0028 2 0 tcp 1000 ------- 0 2.0 1.0 0 0
^^
 
 Could someone please explain how the errors/retransmissions 
 reflect in the output trace file.

 Thank you in advance,
 Neelsh.
