| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Since the development of optical network technology, a lambda grid system sharing computing resouce by wide area optical network has been proposed as grid systems. In the grid system, data stored as the file format. To reduce the influence of file damage and to distribute the load, replica files are stored many servers. Parallel downloading is promising to decrease downloading time, improve transfer rate, and distribute load to many servers. However, parallel downloading triggers many bottleneck links in the network, since many links are used in simultaneity. Therefore the blocking probability of new lightpath set up becomes high. In this paper, we propose a server selection method for parallel downloading in WDM network which considers the wavelength availabilities of each links to decrease bottoleneck links and to enhance the network efficiency. The proposed scheme can optimaly select servers and reduce the blocking probability by considering both wavelength availability for each link and original costs. | |
