[ns] TCP implementation in ns

[Arijit Ganguly <arijitg@tct.hut.fi>]

Hello Seniors
I am using ns-2.1b7a.
I am running FTP with finite file sizes which I specify using "send"
procedure.

Everything is going fine. I just observe that when the connection is
closed, the various events which it had scheduled, continue to be
triggered.

For example, TCP sets a timeout for round trip time. After my transfer
completes, and the connection closes down, I still observe the timeouts
continue to be there in Scheduler's queue and dispatched.

Kindly also let me know whether it is possible to delete connections as
they terminate, becoz in my simulations TCP connections would come and
go stochastically. For such long simulations it would be better if I
could deallocate the memory used my connections that have closed.


Awaiting ur reply
