Re: [ns] Mean Loss Rate Based on Trace File

[Debojyoti Dutta <ddutta@ISI.EDU>]

you can write a simple awkj script to calculate the no of drops
---
BEGIN {c=0;}
$1=="d" && $2="0" && $3="1" && $5="tcp" {c++;}
END {print c;}
---
this awk script will find the no of drop s between nodes 0,1 the traffic
being TCP. this should get you started.
