packet::copy()



Hello,

This is a question about the packet::copy() method defined in ns2. When a
node's replicator produce multiple copies of the original packet and
forward each copy to downstream nodes, these copies are identical,
excepet the uid field, because each new pkt generated will be assgined a
unique uid. But when I look at the output trace file and track any
of the mutlicast pkt, this seems not true, each copy of a pkt has the
same uid as the original pkt. Has anyone notice this? and why?

tks,
