A Survey on FEC Based Packet Loss Recovery Technique in Networks?

We survey a number of packet loss recovery techniques for many applications which are operated using IP multicast. We begin the discussion with the loss and delay characteristics of an IP multicast channel, and from this we show the need for the packet loss recovery. And these recovery techniques may be divided into two classes: Sender-based and Receiver -based. We compare and contrast several sender-based recovery schemes: forward error correction (both media-specific as well as media-independent), retransmission and interleaving. We conclude with a series of recommendations for repair schemes to be used based on application requirements and network conditions.
