RE: [ns] Packet Loss, Delay, Thruput...

[Srihari Raghavan <sraghava@vt.edu>]

Hi,
  Other ways to do the same are

  1. Use Agent/LossMonitor, Agent/TCPSink objects to capture BW information.
Use Agent/TCP for TCP source's view of BW. See ns docs and examples dir. for
further info.

  2. Use trace-all, namtrace-all commands in NS to get traces and you can
analyze them using MS Access and/or Excel to obtain statistics like mean BW,
median etc., I will post some usage examples soon in my website and will
inform the group and if somebody can use it, well and good.

  3. The best place to look for, is the examples directory in ns
distribution. Look out for record{} functions that will show some data
collection.

  4. Try http://mash.cs.berkeley.edu/dist/archive/ns-users/0003/0069.html to
get some ideas on changing the code.

Hope it helps,

One idea could be to write simpke awk or perl scripts. Check the example
scripts in the distribution.
