We present a 2-dimensional n times n dense optical torus network (DOT ) having p = n<sup>2</sup> nodes and l = 2n<sup>2</sup> optical links. Each node consists of a processor and of a router. The links are capable of using 2n-1 wavelength channels. Furthermore, we present an all-optical, collision free routing algorithm for the DOT that is based on(More)
We present an all-optical ring network architecture with logarithmic shortcuts and a systolic routing protocol for it. An r-dimensional optical ring network with logarithmic shortcuts (ORLS) consists of n = 2 nodes and r2 optical links. We study a systolic routing protocol that is based on cyclic changes of the states of routers and scheduled sendings of(More)
