Study on Parallel Data Transmission for Peer-to-Peer Grid

本文研究的是在对等网格环境(P2P网格)中执行的、需要传输大量数据的计算机网格应用程序的数据传输方法。P2P网格是由通过网络相互连接的远程个人计算机(PC)组成的对等网络组成的分布式系统。我们提出了一种通过在两个节点之间建立多个TCP会话并让这些会话协作来加速数据传输的方法。此外，我们还研究了另一种利用类BitTorrent并行传输的加速方法。此外，还考虑了一种利用数据编码提高数据传输效率的方法，从而有效地利用瓶颈通信链路，将P2P网格计算应用到需要传输大数据的数据处理中。

This research is concerned with data transmission method for computer-grid applications that are executed in peer-to-peer grid environment(P2P Grid) and require transmission of large amount of data. A P2P Grid is a distributed system that is made of a peer-to-peer network composed of remote personal computers(PCs) mutually connected by networks. We proposed a speed-up method for data transmission by setting up multiple TCP sessions between two nodes and letting the sessions cooperate. Also we studied another speed-up method by utilizing BitTorrent-like parallel transmission. In addition, a method to improve data transmission efficiency by utilizing data encoding in order to use bottleneck communication link efficiently is considered.By utilizing the results of this research, we can apply P2P grid computing to data processing that requires transmission of large data.
