Media streaming is an important Internet application and has received more and more attention in recent years. Traditional media streaming systems are deployed in a server-client mode which scales poorly with the increasing population of the clients. Peer-to-peer media streaming can greatly enhance the scalability of the system by employing the clients to help forward the media content. In this paper,...
Peer-to-peer overlay networks are widely used in distributed systems. Based on whether a regular topology is maintained among peers, peer-to-peer networks can be divided into two categories: structured peer-to-peer networks in which peers are connected by a regular topology, and unstructured peer-to-peer networks in which the topology is arbitrary. Structured peer-to-peer networks usually can provide...
In contrast to peer-to-peer (P2P) file sharing, video-on-demand (VoD) streaming technology over P2P network is still awaiting breakthrough. The demands on scalability, playback deadlines for all peer nodes and playback continuity under a dynamic peer join/leave situation in a lossy P2P network are the major challenges for deploying a P2P based VoD system. In this paper an efficient weight-based caching...
In this paper, we propose a scheme to apply network coding to heterogeneous peer-to-peer media streaming systems. As most peers in a peer-to-peer media streaming system are individual computers connected to the Internet through access links with heterogeneous link capacities, it is desirable to design an adaptive scheme to make efficient use of the bandwidth of the access links. We propose an adaptive...
Accurate identification and classification of network traffic according to application type is an important element of many network management tasks. In this paper, a P2P network traffic classification method using SVM classifier is proposed. By this method, the P2P network traffic can been classified according to application types with statistical characteristics of network traffic. This paper mainly...
Network coding is a promising enhancement of routing to improve network throughput and provide high reliability. It allows a node to generate output messages by encoding its received messages. Peer-to-peer networks are a perfect place to apply network coding due to two reasons: the topology of a peer-to-peer network is constructed arbitrarily, thus it is easy to tailor the topology to facilitate network...

Reliable multicast is critical to multicast based applications as it provides reliability over the unreliable network. Although the primary function of reliable multicast is loss recovery and flow control which are similar to that of reliable unicast, the inherent property of multicast that multiple receivers coexist in one multicast session imposes new challenges such as acknowledge implosion and...
