A Survey of Packet Loss Recovery Techniques for Streaming Media

Our paper A Survey of Packet Loss Recovery Techniques for Streaming Media was published in the September/October 1998 issue of IEEE Network Magazine.

The paper surveys a number of packet loss recovery techniques for streaming audio applications operating using IP multicast. It begins with a discussion of the loss and delay characteristics of an IP multicast channel, and from this show the need for packet loss recovery. Recovery techniques may be divided into two classes: sender- and receiver-based. It compares and contrasts several sender-based recovery schemes: forward error correction (both media-specific and media-independent), interleaving, and retransmission. In addition, a number of error concealment schemes are discussed. The paper concludes with a series of recommendations for repair schemes to be used based on application requirements and network conditions.

This is an expanded version of the discussion we previously published in RFC 2354.
