In this paper we proposed a software implementation of packet-level FEC coding based on Reed-Solomon code over Galois field. We take advantage of the closure property of Galois field and the transformation capacity of Reed-Solomon code to solve the problem of dateword size expansion in transformation. Using lookup table effectively reduces the complexity in polynomial operation and increases the coding efficiency of software FEC. The algorithm to generate lookup table is also introduced. Experiment results show that the presented coding can satisfied the throughput requirement from most network applications.
