Abstract

Packet losses are bursty in nature since the dominant reason is temporary overload situations in the shared resources over networks. To increase the effectiveness of forward error correction (FEC) schemes, adaptive FEC schemes have been suggested, where the amount of redundancy is controlled according to current network status. In this paper, we propose a gap- based adaptive FEC scheme, which is motivated by the Markov gap model for packet losses, and show that the gap-based adaptive FEC scheme performs better than the adaptive FEC scheme based on the Gilbert model.
