Any full-tcp implementation that supports multiple simultaneous sessions?

[Nabil Bitar <nbitar@gte.com>]

Hi,
I am trying to build a client-server simulation using full-tcp. The
full-tcp agent that I got in ns2 does not support multiple sessions
associated with a single tcp port. Is there any socket-like functions
for ns and/or full-tcp implementation that supports what I am looking
for and that I can have access to? Your prompt response will be greatly
appreciated.

Thanks,
Nabil.
