hi all, i was hoping to get some help towards simulating packet marking for ip traceback. some of the older posts advise tackling this issue by introducing a new field in the ip header but i am not sure of which files in particular to edit and how to make sure that the routers probabilistically change that field to put their address or just their unique node number. Any advice on the matter, or sample code for those users who have done this before, would be greatly appreciated. i am using ns2.34 on ubuntu11.
thank you in advance. anky
