Aiming at the problem of how to efficiently manage and use cache content in P2P VoD system, a distributed cache management model (DCMM) for P2P VoD is proposed. In the model, peers distributed cache management model for P2P VoD systems whose caching media segments integrate a full program are organized into a ring. Any segment of a specific program can be… (More)
In order to effectively improve the success rate of transactions among nodes of p2p patch distribution system, this trust model was introduced to the p2p patch distribution system, the design of trust model was given and the specific implementation of each module was described in detail, finally the performance of trust model achieved were tested.
Data allocation in layered P2P streaming has been proved to be a NP-Complete problem. The existing algorithms are heuristic and based on the greedy idea, which can not get the global solution. In order to develop a new algorithm for this problem, we define the concept of ‘Data Blocks for Choosing’, set up a mathematic model of integer… (More)
