A scalable and flexible photonic interconnection network architecture suitable for warehouse-scale networks is proposed. The architecture comprises three functional layers: physical, optical, and logical layers. The network topologies achieved at the layers are tree in the physical layer; hypercube in the optical layer; and relatively lower dimensional topologies like two-dimensional mesh, tree, and ring in the logical layer. The application of the appropriate network configuration in each layer by making good use of wavelength division multiplexing technology realizes a truly scalable and flexible network. Evaluation of the physical link requirements reveals the scalability of the proposed network architecture.
