Re: [ns] f in the trace file

[Ismail Ari <ari@cse.ucsc.edu>]

Please refer to:
/ns-2../cmu-trace{.h, .cc}

        if(tracetype == TR_ROUTER && type_ == SEND) {
                if(src_ != src)
                        op = FWRD;
        }

You usually see 'f' is ad-hoc mobile networking, where all nodes have to
contribute to routing. classifier-addr (IP) in the node "forwards" the
packets that are not destined to itself towards the target (destination),
by putting in on to the linkhead for the related target. If packet were
destined for itself, classifier-IP would pass it on to relevant
classifier-port in the same node. This is classic IP forwarding..
