We present a design of a scalable interconnection network that possesses a hierarchical structure. We also present the network topology, features, and performance analysis. The proposed network is well suited to optical implementation and will be used in massively parallel systems. This network is called a SCalable OPtical Interconnection Network (SCOPIN). SCOPIN is a single-hop, scalable, flexible, fault-tolerant interconnection network that uses WDM (Wavelength Division Multiplexing) techniques to achieve high performance. Here single hop refers to the ability of each transmitter of an access node to directly reach the receivers of every access node by one of its wavelength-channels. The proposed network is designed to be size- and wavelength-scalable. The network structure consists of a local ncube cluster decomposed into transmitter/receiver groups that are scalable and a global torus link network that connects these local ncube clusters. This paper takes a look at the feasibility and structural aspects, which include the transit nodes in the optical medium and the transmitter/receiver configuration. These in turn determine the physical and virtual topologies respectively.
