Replica selection for parallel and multi-wavelength downloading in optical grid networks

Abstract : This paper proposes a replica selection scheme for parallel and multi-wavelength downloading in optical grid networks. In optical grid networks, files replicated at multiple sites are downloaded in parallel to reduce downloading time. Furthermore, each replica is downloaded with multiple wavelengths. Although parallel and multi-wavelength downloading can reduce downloading time, they raise blocking probability of file downloading. To resolve this problem, the proposed scheme selects replicas and establishes lightpaths based on wavelength availability. Through simulation experiments, we show that the proposed scheme efficiently improves blocking probability without increasing average downloading time.
