In this letter, we proposed a novel efficient infrastructure for grid based on "dual-link-server" optical burst switching (OBS) network to improve the performance of burst contention resolution scheme. The functional block required to support grid services is identified as one uniform grid network interface. The details of associated challenges in terms of functionality and technology were discussed and solutions were obtained. Dual-link-server model is used to solve the collision problem. The numerical simulation was performed to evaluate the performance of the proposed scheme. Techno-economic analysis results show that "dual-link-server" architecture for OBS grid is efficient and cost-effective.
