The enclsoed mail suggested using ndatapack_ and nrexmitpack_ for calculating goodput.
However, nrexmitpack_ does not seems to work for TCP Vegas. Can anyone
tell me whether it's a program omission or I have done something wrong
?

In tcp.h: 299: TracedInt ndatapack_; /* number of data packets sent */ 304: TracedInt nrexmitpack_; /* number of retransmited packets */ therefore, at the end of the connection, [ndatapack_ - nrexmitpack_] should give you the number of unique packets. Give it a try and tell us about it. -- Lucas Barri�re [email protected] http://aemiaif.lip6.fr/etudiants/lucas UNIX is user-friendly. it's just selective about who its friends are. ----- Original Message ----- From: "Fusun Inanc" <[email protected]> To: <[email protected]> Cc: <[email protected]> Sent: Thursday, March 23, 2000 10:28 PM Subject: [ns] goodput for TCP connection > Hi everyone, > > I would like to calculate the goodput for a TCP connection. > I want to count the number of unique packets, (not the ones > which are repeated) I could count them from the trace file > one-by-one but I am running the simulation for 50sec. > and I don't think this is a good idea :)) > > I was wondering if someone has a code to calculate the goodput. > I have a code to calculate the TCP throughput though. > I would appreciate any help. > > Thanks, > > Fusun Inanc >
