Abstract

This paper considers the packet recovery performance of forward error correction (FEC) for a single-server queueing system with a finite buffer fed by two independent input processes; one is a general renewal input process in which the interarrival times of packets are independent and identically distributed according to a general distribution, and the other is a Poisson arrival process. We analyze the packet- and block-level loss probabilities, and investigate the recovery performance of FEC at block level. Numerical examples show that the block-loss probability is significantly improved by FEC when the system can only accommodate a small number of packets. It is also shown that FEC recovery is more effective than packet buffering when the traffic intensity is large.
