[ns] routing protocol for wired scenario

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.
