FORWARD ERROR CORRECTION IN PACKET NETWORKS

摘要

Methods and apparatus are provided to allow reliable data transport in a packet-based network. A network node encodes (621) error correction packets associated with data packets at a network-layer and forwards (627) the error correction packets with the data packets. The error correction packets are decoded (723) as needed to recover data packets lost or dropped during transmission. The mechanisms are applicable for unicast and multicast networks and function even with network topology changes.
