Introduced the design of accelerated transmission service system.Using TCP protocol and the underlying routing mechanism of P2P network, the system can select high-performance peer nodes, coordinate the transmission status of each node, and dynamically adjust the transmission rate when network and node performance changes , So as to dynamically adapt to changes in network performance at a lower cost.The performance of the system was evaluated by simulation and the relationship between network traffic and bandwidth utilization and network throughput was analyzed.The results show that in the accelerated transmission system , The mutual harmony between the receivers and the cooperation among multiple neighboring nodes enable the data transmission speed to be accelerated and the overall system performance to be improved.
