英文摘要	Under the current and foreseeable limitations of optical technology, performance of optical packet-switched networks is mainly hampered at the network node by resource contention. The contention is serious constraints on the capacity of the network. Therefore, most of the research activities are focus on the node design. Unlike the existing research activities are focus on the node design, we proposed a new concept-server vision for optical packet-switched networks in this paper. From the point of view of server vision, the network resource is categorized into three types-the access server, the node server and the link server, based on the fact that the network resource performs the different function for the traffic. After present the server vision optical network, we presented two novel approaches-two link server solutions-to erase the resource contention. One solution is the packet calking, and the other solution is the dual-fiber link. We have developed some scenarios to validate these solutions. Simulation results show that the dual-fiber link can reduce the contention in terms of orders of magnitude in optical packetswitched networks without optical buffers and wavelength conversions.
