I am required to demonstrate and simulate the hybrid IP traceback (Using packet marking and packet logging schemes) in NS3. In Packet marking, the node marks each incoming packet with its nodeid at the IP header IDENTIFICATION field, and in packet logging the node records the digest of the IP header in the node's table which contains neighboring nodeid and corresponding packet digest.. Finally when an attack packet arrives at destination, the victim triggers the traceback process by which the attack path is reconstructed by the help of the logged and marked data at each node.

Thanks for your quick response sir.
The thing is; lets assume we have 20 nodes in a network simulator [ns3]. Node1 sends a packet to node20. i want to mark this packet with the nodeid at each node as it visits the node as well as put the digest of that packet in each node so that the packet path can be reconstructed immediately. Here is the dummy algorithm I took from some paper if it helps.
For each packet p
IF router ID number i carried by p is valid (i.e. is neighbor)
IF the logging flag bit in p is 0 [1st bit of 16 bits is set for flag)
compute the digest of p (any digest can be used)
store the digest in the digest table corresponding to i (in that R)
mark p with R’s ID number
set the logging flag bit in p to be 1 (showing that it is logged in this R)
ELSE
mark p with R’s ID number
set the logging flag bit in p to be 0
ELSE
mark p with R’s ID number
set the logging flag bit in p to be 0

Write the code yourself. You need to spend more time.

I am not clear with what you mean by "outdated tutorial" Mr. Tommaso Pecorella. I thought this site is for sharing knowledge and I don't think there is nothing like outdated tutorial as far as someone is looking for it. Please just help if you can.
