P2P locality awareness architecture in Ethernet Passive Optical Networks

摘要

The P2P lives streaming nowadays becomes more popular and begins to take a larger share of bandwidth together with the Internet video calling. Furthermore, a large scale peer-to-peer (P2P) live streaming has recently been successfully and commercially deployed to provide either live streaming or on-demand video streaming. Cisco predicts that 60% of video traffic worldwide will be consumed by these P2P applications in 2015, which is enough to make any Internet Service Provider (ISP) straitened. In particular, the major challenge that has received significant attention is that many network oblivious P2P applications without locality awareness of ISP boundaries that lead to inefficient Internet resource utilization due to the Inter-ISP traffic cost. Consequently, we propose P2P locality awareness architecture in Ethernet Passive Optical Network (EPON) that mitigates Inter-ISP traffic by optimizing peering locality for P2P live streaming. We design mechanisms in ONU. These mechanisms can reduce inefficient Internet resource utilization at the server sides and improve each peer QoS.
