MULTISEGMENT LOSS PROTECTION

摘要

A method for providing error correction of media packets. Service nodes associated with a core network segment use a first error correction process, and service nodes associated with an access network segment use a second error correction process. Service nodes associated with a local network segment may use a third error correction process. The present invention utilizes different error correction processes on different network segments as appropriate. Service nodes may receive indicators from monitoring agents that error correction is insufficient and, in response, a service node may increase an amount of error correction associated with a network segment. Media packets may be interleaved in a forward error correction (FEC) block in a manner that increases an amount of packet recovery.
