[LCP]userspace TCP

[Srinath Thiruvengadam]

hello all,

well, i have to implement tcp in userspace.. the setup is something like
this.. 
i have to implement a program that runs tcp in usespace on a firewall.
this 
should intercept packets that are sent from client to server.

now, i dont know anything about userspace tcp.. how do i go about this ?
do you 
know of similar projects that were done before ? where can i find more 
information about this ??

Million thanks and best regards,
srinath
