an opnet model for p2p video streaming over wired, wireless, and mobile networks

Video distribution over the Internet has already become a major application due to users’ growing demand of Video content and continuous growth of network technologies. Recently, as the rapid growth in the number of Video delivery systems, people ask for more and more video resources, which cause overload on network resources. Peer-to-Peer (P2P) network is an important component to implement such systems, how to quickly and efficiently deliver the video resources in P2P networks has become one of the most critical issues, at the same time, this is one of greatest concern to users. One major quality of video delivery metric is playout latency which can be considered as one of the key challenges that face many researchers nowadays. One major quality of video delivery metric is playout latency which can be considered as one of the key challenges that face many researchers nowadays. On the other hand, as cloud computing grows rapidly and more Internet users prefer to watch video or listen to audio online instead of downloading them to their local disk, it is critical and important to provide a cloud data storage and media delivering services continuously to deal with VoD systems. To address the above issues, this paper proposes a novel cloud framework for P2P VoD system. i'd like to purchase a p2p model using opnet modeler that simulates video on demand like youtube site. but i need to add some contributions such as pre-distributing the vidoes according to user intersets.
