Abstract(in English) This paper proposes a replica selection and transmission scheme in optical gird networks. In optical grid networks, in order to distribute loads, a large amount of data is replicated on storage servers as files, and clients download those replicas. The proposed scheme provides replica selection based on wavelength availability which is collected by signaling of backward reservation. Furthermore, the proposed scheme introduces a multi-wavelength transmission which determines the number of wavelengths used for each replica transmission based on wavelength availability. Through simulation experiments, we show that the proposed scheme can improve the blocking probability of file transmission and the average transmission time efficiently.
