Abstract :
A lightwave packet network architecture suitable for local applications (office, campus, and metropolitan areas) is proposed and analyzed. In describing the architecture, careful distinction is made between the physical topology depicting the physical-link arrangement and the connectivity graph showing logical connections among various nodes. Also emphasized are the practicality of implementation, cost, and upward compatibility with future technology. The physical layout of the network is based on a multifiber ring whereby a cable consisting of multiple fibers is deployed as a passive interconnect fabric for the entire network. A node is connected into the network by intercepting three fibers in the cable and inserting it between the cut fibers. Packets received are examined for their destination addresses and judiciously routed to the appropriate outbound lines or the local exit. To support a network of N nodes, the number of fibers required in the bundle is only √N+4. This is a result of employing a specific connectivity graph in which the N nodes are arranged in a √N×√N grid structure with both crossbar and criss-cross (diagonal) connections
