Abstract
A method and system for providing protection of data communications in packet-based networks is provided, using a combination of unicast to multicast conversion and providing formation of virtual output queues (VOQs) which are separate for each pair of the target port and protection ports on the target network device. As a result, the system requires less bandwidth resources and reduces or eliminates network performance problems associated with other existing solutions.
