Conceptual development of resources discovery in the proposed hybrid P2P video streaming

We present the design of a hybrid Peer-to-Peer (P2P) system for video streaming. In this paper, we address the availability, accessibility and lookup service of files. We use the advantages of server-client business model to search and retrieve the information. We implement the base ontology of video domain repository so that the final result may be different and provide more results from the keyword search. To provide the dynamic standby peer, we use checksum value as an indicator to search an identical content in the Peer-to-Peer network. We hypothesize that, by using server-client searching in Peer-to-Peer application, we can reduce the latency lookup services, path length, peer load and network traffic

Video Management in Peer-to-Peer Systems

Providing scalable video services in a peer-to-peer (P2P) environment is challenging. Since videos are typically large and require high communication bandwidth for delivery, many peers may be unwilling to cache them in whole to serve others. In this paper, we address two fundamental research problems in providing scalable P2P video services, namely (1) how a host can find enough video pieces, which may scatter among the whole system, to assemble a complete video, and (2) given a limited buffer size, what part of a video a host should cache. We propose a new distributed video management technique. Our scheme organizes hosts into a number of cells, each of which is a distinct set of hosts which together can supply a video in its entirety. A client looking for a video can stop its search as soon as it finds a host that caches any part of the video. Caching operations can be coordinated within each cell to balance data redundancy in the system. Our extensive study on a Gnutella-like simulation network shows convincingly the performance advantage of the new scheme
