Abstract
Packet switch operating methods and packet switches receive a packet from a port and then forward the packet to the port from which the packet was received. The packet switch receives a packet having a first transport identifier from a port, modifies the packet to have a second transport identifier, and forwards the modified packet to the port while retaining a layer-two source address and a layer-two destination address. Other methods and packet switches transmit modified, duplicated packets on a single port. The packet switch receives a packet on a first port and creates at least one duplicate of the packet. The packet switch modifies the packet and the duplicate so that they have different transport identifiers. The packet switch then transmits the modified packets on a single port.
