We have discussed a framework to reduce the response times of simultaneous large file transfers by many users in a large-scale wide-area network. In that, on top of IP packet routing, the files are stored and relayed among special advanced relay nodes arranged on the network. A variety of essential techniques in terms of a high-speed fair data transfer between sender/ relay/ receiver nodes, a temporal and spatial file relay scheduling, and an effective arrangement of the relay nodes were proposed and then evaluated through simulations and/ or PC and Openflow-based prototype experiments.

我们讨论了一个框架，以减少在大规模广域网中许多用户同时传输大文件的响应时间。在这种情况下，在IP包路由的基础上，文件被存储并在网络上安排的特殊高级中继节点之间转发。在发送/中继/接收节点之间的高速公平数据传输、时间和空间文件中继调度以及中继节点的有效安排等方面提出了各种基本技术，并通过仿真和/或基于PC和openflow的原型实验进行了评估。
