hi all,
I am about to embark on a projectthat involves creating a program that accepts packets from an interface and outputs them after a certain amount of delay and jitter on another interface. Kind of like a simulation of the internet.

Now so far, I know that when u want to recieve somehting u open a socket on a certain port. Now in my case how should the sockets be different? and how can i retain the destination IP so that i can forward the packet. This should be the same socket operation of a firewall i think.

can anyone suggest any reading material or google keyword or similar project for me to look at.

thanks
