Abstract

We propose a model-based analytic approach for evaluating the overall efficiency of Forward Error Correction (FEC) coding combined with interleaving in combating packet losses in IP networks. The loss of various packets during the data transmission can be reduced by using FEC coding. This unified approach provides an integrated framework for exploring the tradeoffs between the key coding parameters such as interleaving depths, channel coding rates and block lengths. The Reed-Solomon codes facilitate the selection of optimal coding strategy used for text based and multimedia applications with various user Quality-of-Service (QoS) requirements and system constraints. In this paper, we have evaluated the efficiency of FEC coding with interleaving in IP networks and observed that 99% of efficiency of error correction in the network.
