TCP WESTWOOD

ns-2 Modules

The ns-2 modules linked by this page are working versions of TCP Westwood.

In order to run your own simulations, you should:

• Get ns version 2.1b6

• Add the module tcp-westwood.cc to the main 'ns' directory, and modify the original Makefile so that it compiles and links the new module

• Substitute the files tcp.cc  and tcp.h with the original ones by the same name. This is probably a bit crude, and if you need to keep your own versions of those files, you will need to do a bit of hacking and just introduce the modifications.

• Add the following lines to ns-default.tcl (it can be found in the tcl/lib directory):
  
  

  Agent/TCP set current_bwe_ 0
  Agent/TCP set last_bwe_sample_ 0
  Agent/TCP set unaccounted_ 0
  Agent/TCP set fr_a_ 1
  Agent/TCP set min_rtt_estimate 10000

  Agent/TCP/Westwood set lastackno_ 0
  Agent/TCP/Westwood set lastackrx_ 0
  Agent/TCP/Westwood set fr_alpha_ 0.9
  Agent/TCP/Westwood set filter_type_ 1
  Agent/TCP/Westwood set tau_ 1.0
