We survey a number of packet loss recovery techniques for streaming
audio applications operating using IP multicast. We begin 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.
We compare and contrast 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. We conclude with a series of
recommendations for repair schemes to be used based on application
requirements and network conditions.
