An optical interconnection architecture is proposed, which is based on optical ring and torus. The proposed optical interconnection network combines advantages of both ring and torus, e.g., simple node interface, constant node degree, better support for local communication and remote communication, wide bisection and good scalability etc.. This architecture could be used to connect thousands of processing elements in massively parallel computer systems while maintaining a low latency and high bandwidth. The comparison with other popular networks is made, and the result shows that RTOIN (Ring based Torus Optical Interconnection Network) has pretty good node degree, network diameter, the number of links, bisection width and average message distance. Also, the result shows its excellent scalability, so it will probably be widely used in the area of parallel computing in future.
