A system and method for modeling the replication of a packet uses a header that contains unique information relative to the replicated packet, and a pointer to the information that is common to the original packet. At each level of the protocol hierarchy, and particularly at the transmission layer, the unique information is contained in the header information that is added at that level, while the common information is the information in the protocol stack created prior to the appending of this header information. Only network elements that traverse and modify the contents of the prior protocol headers are fully instantiated, and thus the resources required for replicating packets is substantially reduced.
