| 摘 要： | 介绍了加速传输服务系统的设计.借助TCP协议和P2P网络的底层路由机制,系统能够选择高性能的对等节点,协调各个节点的传输状态,在网络和节点性能发生变化时进行动态调整传输速率,从而以较低的开销动态适应网络性能的变化.通过仿真对系统性能进行了评价,并对网络流和带宽利用率、网络吞吐量之间的关系进行了分析.结果表明:在加速传输系统中,接收方之间的相互谐调和多个邻居节点间的相互协作,使得数据传输速度得以加快,系统总体性能得以提高.

| Abstract: | The design and evaluation of accelerated transmission (AT) systems in peer-to-peer networks for data transmission are introduced.Based on transfer control protocol (TCP) and peer-to-peer (P2P) substrate networks, AT can select peers of high performance quality,monitor the transfer status of each peer,dynamically adjust the transmission velocity and react to connection degradation with high accuracy and low overhead.The system performance is evaluated by simulations,and the interrelationship between network flow,bandwidth utilities and network throughput is analyzed.Owing to the collaborative operation of neighboring peers,AT accelerates the process of data transmission and the collective network performance is much more satisfactory. |

| Keywords: | peer to peer network transfer control protocol (TCP) available bandwidth |
