P2P live streaming system is one of the most popular Internet applications which develop rapidly in the past decade. However, some common problems, such as long startup delay and unsmooth playback, seriously restrict user's experience on live streaming. In this paper, we propose a novel but simple scheme, namely guarantee mechanism of contingency resource (GMCR), which can improve the quality of service...
Live streaming video has become one of the most popular P2P applications with its high-quality performance and playing effect. Since the real-time requirement, live streaming systems have to adopt an appropriate neighbor selection mechanism to realize effective content distribution. This paper takes PPLive which is a classic P2P IPTV system as the object to measure and analysis. We pay our attention...
Identification of various P2P flows accurately is fundamental for network management. To obtain P2P flow information in real-time and low price, a distributed extensible architecture for P2P flows identification called DEAPFI is proposed. DEAPFI decentralizes functions of flow identification and statistic on different PC, which is composed of identification system (IS) and statistic system (SS) respectively...
A hybrid system of cellular mode and the peer-to-peer (P2P) mode is considered in this paper, where the cellular uplink resource is reused by the P2P transmission. In the objective of overall system throughput maximization, we addresses the problem of distributed power control of P2P transmission in the hybrid system model. Some preliminary results of the problem are presented first to investigate...
To resolve the topology mismatch problem when applying peer-to-peer (P2P) file sharing over mobile ad hoc networks (MANETs), a cross-layer protocol is proposed by combining P2P file discovery with the route discovery process at the network layer. In this protocol, the functionality of conventional routing protocols is extended to identify the file discovery request, and P2P connections are established...
