[ns] DropTail Queue

[Suman Nath <sknath+@cs.cmu.edu>]

 Hi
 
 If two identical TCP flows (same parameter, going through similar
 links) share a congested link and the link has DropTail queuing, NS shows
 one of the flows to suffer most (if not all) packet drops, while the other
 flow suffer almost no loss. (This has also been shown in Marc Greis's
 tutorial, in "Monitoring the Queue Seciton"). 
 
 I think this is not the case in real world.
 
 Can anyone tell me how I can avoid this effect, and see real-world like
 behaviour.
 
 Thanks,
 Suman Nath
