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