| Research Abstract |
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.
