Lab 6: Hacking TCP to compete with UDP

In previous exercise, the TCP flow seems to occupy a little less share of the bandwidth. Can you modify the existing TCP (Tahoe) implementation in ns-2 and make it more aggressive? For example, make TCP send packets in constant window size.

6. More Aggressive TCP

Locate tcp.cc
Do your chagnes (whatever you think will enhance TCP's bandwidth share)
Re-compile ns
Re-run the previous simulation and see if it actually improve TCP's bandwidth share
You should also consider modifying the tcp setting in the simulation script
