Parity streams: a novel FEC scheme with the stream control transmission protocol

Conventional packet-level forward error correction (FEC) is found inapplicable with the stream control transmission protocol (SCTP), because of its partially ordered transport feature. To provide error resilience for respectively ordered data streams, we propose to generate "parity streams" parallel to the data streams. The use of parity streams allows multiple data streams to be protected concurrently and also scalably. For instance, unequal error protection (UEP) can be easily implemented within and/or across data streams, which is attractive to streaming-media applications where preferential treatment on different data units is desired
