ABSTRACT:
This invention includes methods and packet switches that modify duplicate packets to have different transport formats. A packet switch receives a plurality of duplicate packets from a switching fabric and modifies two or more of the duplicate packets so that the modified duplicate packets have different transport identifiers. The packet switch then transmits one of the duplicate packets on each of a plurality of ports of the packet switch.
