Abstract
Described are a system and method for providing protection switching and bandwidth sharing in a network. A first endpoint device adds a sequence number to each packet to produce a stream of numbered packets and provides a plurality of packet streams from the stream of numbered packets. The first endpoint device forwards a first packet stream over a first path and a second packet stream over a second path separate from the first path. In one embodiment, the packet streams are identical. In another embodiment, the packet streams are different. A second endpoint device receives the first packet stream over the first path and the second packet stream over the second path. From the packet streams, the second endpoint device determines whether each packet in the packet streams is to be included in an output packet stream based on that packet's sequence number.
