About TCP

[Shaogang Chen <shaogang@ecn.purdue.edu>]

For those of you who are familiar with ns:

>From my understanding to current version ns, the connection between two
agents is set up staticly. The data is not actually transmitted from
a sender to a receiver. The data length is just used to compute transmission
time. 

Right now, I might want to implement TCP state machine in ns, so connections
can be set up on request. Also data is transmitted from a sender to a receiver.
My question is how hard it is to do this? Do you have any intention to
implement ns as this way in the future?

Thanks
