Optical grid synergy with peer-to-peer

As grid computing continues to gain popularity in the industry and research community, it also attracts more attention from the customer level. The large number of users and high frequency of job requests in the consumer market make this scenario a challenge for grid computing. Clearly, all the current client/server(C/S)-based architectures will become unfeasible for supporting large-scale grid applications due to their poor scalability and poor fault-tolerance. In order to address this issue, a novel C/S and peer-to-peer hybrid architecture to realise a highly scalable and flexible platform for optical grid is proposed here. The anycast algorithms, which are used to search suitable resources for job requests in this hybrid architecture, are also investigated in detail. Simulation and experimental results show that the proposed architecture is suitable and efficient for grid applications, and it outperforms C/S-based architecture in a large-scale grid environment.
