Peer-to-peer application-aware mechanism for enhancing video streaming in enhanced EPON

Abstract

Today, the popularity of peer-to-peer (P2P) applications have increased significantly globally. It starts previously on music file sharing system and progressively develops in many application domains. Currently, P2P applications are able to offer various emerging applications ranging from music, video, IPTV and so on. P2P applications are an attractive service because it allows users for accessing different P2P services over Internet, permitting anybody to become a content provider so that anyone can share content (i.e., file, music, video, etc.) with other users. In P2P network, the mapping between the overlay network topology and underlying physical network topology has a significant impact on users Quality-of-Services as well as Internet Service Providers (ISPs). In particular, the major challenge that has received significant attention is that many network oblivious P2P applications without awareness of ISP boundaries that lead to inefficient Internet resource utilization and immense costs for ISPs due to the Inter-ISP traffic cost. Therefore, in this paper we propose an application-aware mechanism in EPON that can reduce Inter-ISP traffic by optimizing peering locality, and at the same time enhancing the users QoS. Simulation results show that our proposed application-aware mechanism can reduce the costly Inter-ISP traffic and improving overall system performances such as delay.
