BANDWIDTH EFFICIENT FEC SCHEME SUPPORTING UNEVEN LEVELS OF PROTECTION

摘要

In one embodiment, a device in a network splits each of a plurality of packets of two or more data streams into an equal number of fragments. The number of fragments for packets of a particular one of the streams controls the level of error correction for that stream. The device generates recovery symbols for the fragments for each of the plurality of packets. Each of the plurality of packets has an equal sum of fragments plus recovery symbols. The device multiplexes the fragments and recovery symbols for each of the packets, to form a set of new packets. The device sends the set of new packets to one or more recipients in the network.
