MULTICAST/BROADCAST EXTENSION TO A POINT-TO-POINT UNICAST-ONLY PACKET SWITCH SYSTEM

摘要

A method and system for routing a multicast packet through a unicast packet switch network of devices. A virtual destination group, which includes destination devices of the multicast packet, is defined, and then the virtual destination group is mapped to an unused unicast destination encoding in routing tables of the devices. The multicast packet is then routed from a source device to the destination devices using the routing tables.
