hi all, i was wondering if anybody has access to a tutorial on how to implement a protocol for wired scenarios. i find that a lot of the literature available is for wireless scenarios with adhoc routing. i particularly am interested in figuring out how to adjust the function in NS2 that is responsible for forwarding packets. The problem i am dealing with is packet marking and i want to find a way to adjust a variable in a packet header for every packet that passes through a node. so all i need to do is access a field of the packet, and change it and every router should be able to do this.
does anyone have any ideas on what i should do? if so, your feedback would be highly appreciated. thank you very much. anky
