| 摘 要： | 设计并实现了一种结合了“并行TCP”和“多路径”的数据传输技术，利用覆盖网络〖BP（〗（Overlay Network)〖BP）〗中的节点作为中转节点，在数据传输过程中，采用多条性能优良的间接路径，并且在每一条路径上开启多个TCP连接。解决了以下三个关键问题：1）如何选取性能相对优良的路径;2）如何动态地为网络路径选择最佳的并行TCP连接数;3)如何根据网络背景流量的变化，在多条路径之间动态地调度分配数据包。所实现的数据传输技术完全基于应用层，不需要修改TCP协议也不需要下层路由器的支持，简单有效地提高了网络传输速度。

| Abstract: | A new technology combining parallel TCP and multi-pathing was designed and implemented.It used overlay network nodes as interim nodes.Besides,in the process of data transmission,it used more than one excellent performance indirect path,and opened multiple TCP connections on each one.Three key problems were solved:how to select the path with higher performance;how to dynamically select the best parallel TCP connection number;how to dynamically arrange data packages in multiple paths according to network flow... |

| Keywords: | data transfer path selection dynamic selection best parallel TCP connection number Peer-to-Peer (P2P) network |
