work-optimal routing in wavelength-division multiplexed three-dimensional dense optical tori
In this paper, we present an all-optical network architecture and an all-optical router for it. The dense 3-dimensional optical torus network (WDOT) consists of an n x n x n torus, each node having a processor. The number of processors of the network is P = n 3 and the number of optical links is L = 3n 3 . Routing is based on the scheduled transmission of packets and wavelength-division multiplexing. The routing protocol ensures that no electro-optical conversion is needed at the intermediate nodes and all the packets injected into the routing machinery reach their targets without collisions. A work-optimal routing of h-relations is achieved with a reasonable size of h ? ?(P log P).
