Based on the structure and operation characteristics of smart distribution network as well as the requirements of fault self-healing system, a distributed fault self-healing system is proposed. The system structure, and the function of distributed smart terminal unit(DSTU) are designed. Taking the characteristics of fault self-healing system into consideration, the article proposes an identification...
For lack of effective resource adjustment method, the supply-demand relationship of each resource in P2P content delivery system are often unbalanced. Especially after a popular content releasing, a burst of downloaders often can't find sufficient uploaders and their request may starve the upload capacity of server. Therefore the overall system QoS may be degraded. To tackle such issue, this paper...
Nowadays, as the fast growth in population of p2p VoD system, user behaviors are playing an increasingly crucial role for the performance of system. In this paper, the user watching and sharing behaviors of p2p VoD system were studied by analyzing a large amount of real data. Then, a comparison between user behavior in p2p VoD system and other main kinds VoD systems was made. After that, a mathematic...
Recently, as the rapid growth in the number of VoD system user, people ask for more and more video resources, which cause overload on server. Therefore, how to use the capability of peers to alleviate the server loading and at the same time maintaining the streaming performance becomes a new challenge for P2P technology. In this paper, after analyzing a large amount of data, we present some valuable...
Recent few years, many p2p VoD softwares are widely applied through out the Internet, which gives us an opportunity to study user watching behavior of p2p VoD system at large scale. Many previous works on this area directly regard peer's information transmitting log such as buffer message as peer's watching behavior log. However, the effect of prefetch strategy is not considered. In this paper, we...
