Forward Error Correction Algorithm
Abstract This document describes how to use Forward Error Correction (FEC) codes to efficiently provide and/or augment reliability for bulk data transfer over IP multicast. This document defines a framework for the definition of the information that needs to be communicated in order to use an FEC code for forward error correction rate bulk data transfer, in addition to the encoded data itself, and for definition of formats and codes for communication of that information. Both information communicated with the encoded data itself and information that needs to be communicated 'out-of-band' are considered. The procedures for specifying new FEC codes, defining the information communication requirements associated with those codes and registering them with the Internet Assigned Numbers Authority (IANA) are also described. The requirements on Content Delivery Protocols that wish to use FEC codes defined within this framework are also defined. The companion document titled "The Use of Forward Error Correction (FEC) in Reliable Multicast" describes some applications of FEC codes for delivering content. This document obsoletes RFC 3452.

FEC [5], [24] is a good example of an error correction code, which is extensively used in real-time wireless applications [25] and wireless networks [26]. A key measure of efficiently encoding blocks of forward error correction data using correction codes is information rate or code rate. "[Show abstract] [Hide abstract] ABSTRACT: The emergence of multihop wireless networks and the increase in low-latency demands of error tolerant applications , such as VOIP, have triggered the development of new protocols and mechanisms for recovering failed packets. For example, recovering partially corrupt packets instead of retrans-mission has emerged as an effective way to improve key network performance metrics such as goodput, latency, and energy consumption. A number of similar and interesting solutions have been proposed recently to either reconstruct or process corrupt packets on wireless networks. The proliferation of multimedia services on 3G and LTE networks, and the stringent quality of service requirements for these applications have given birth to robust codes and new error tolerant mechanisms for packet delivery. Despite years of active research in the field, we lack a comprehensive survey that summarizes recent developments in t
