An efficient method to reduce peer-to-peer streaming latency

Abstract

Recently a large number of multimedia content is streamed to millions of users through peer-to-peer networks. Most of them are based on an unstructured mesh-based topology. It results to a long end-to-end delay. Based on this consideration, this paper proposed a novel topology construction approach, LayerP2P, to construct a low-latency structured overlay for live streaming. It organize peers into a multi-layer mesh-based topology. Since the maximum relay hops in the overlay are bounded by the number of layer, the average end-to-end delay is cut down. At the same time, the overlay keeps resilient by self-organized peers in a decentralized way. Experiments carried out over a simulated network of up to 500 peers illustrate the effectiveness of our approach. © 2008 Springer.
