Those replicas are downloaded in parallel in order to reduce downloading time. Furthermore, each replica is downloaded with multiple wavelengths. Although parallel and multi-wavelength downloading reduce downloading time, they raise blocking probability of file downloading. This is because they use a lot of wavelength resources and thus often generate bottleneck links. To resolve this problem, this paper proposes a parallel and multi-wavelength downloading scheme for optical grid networks. The proposed scheme provides replica selection, route selection, and wavelength selection for parallel and multi-wavelength downloading. In the proposed scheme, clients dynamically select combinations of a replica, a route, and a wavelength in such a way that they suppress the generation of bottleneck links. Through simulation experiments, we show that the proposed scheme efficiently improves blocking probability of parallel and multi-wavelength downloading.
