Paper Abstract

Grid computing enables the sharing of a wide range of geographically distributed resources including computers, storage systems, specialized devices, and network infrastructures that are owned and managed by different organizations for solving large scale computational and data intensive applications. Optical transports allow a more efficient design by providing the means to transmit large amounts of data with low cost and reliability. Group multicasting is considerable communication requirement in grid networks. Routing and wavelength assignment algorithm can greatly influence the performance of optical network, such as network blocking, resource utilization. This paper investigates the problem of routing and wavelength assignment for group multicast in optical grid networks based on network resource reservation. A minimum resource fragmentation summation (MRFS) algorithm is proposed, presented and evaluated. Simulation results show that the proposed algorithm represents higher performance on reducing blocking probability and increasing resource utilization.
