| 英文摘要: |
| In order to solve the problem that the existing data scheduling algorithm cannot make full use of neighbors’ bandwidth resources when allocating data request among several senders in the multi-sender based P2P streaming system, a peer priority based scheduling algorithm is proposed. The algorithm calculates neighbors’ priority based on peers’ historical service evaluation as well as how many wanted data that the neighbor has. The data request allocated to each neighbor is adjusted dynamically according to the priority when scheduling. Peers with high priority are preferred to allocate more data request. Experiment shows the algorithm can make full use of neighbors’ bandwidth resources to transmit data to reduce server pressure effectively and improve system scalability. |
