In this paper we present an all-optical network architecture and a two-phase routing protocol for it. The layered sparse optical torus (LSOT) of degree d consists of n x n nodes at the layer 1, where n = d**2. Processors are deployed diagonally at each i'th diagonal. The overall number of processors is then P = d**3. Additionally a LSOT consists of d**2 d x d subnetworks at the layer 2. 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-relation is achieved with the size of h in θ(P).
