Media Access Protocol Selection for Hierarchical Optical Ring Interconnection Network (HORN)

By Thomas S. Jones and Ahmed Louri

Abstract

Optical fibers offer high potential for interconnection networks (INs) for multiprocessing and multicomputing due to their ability to carry a large number of wavelengths at high transmission rates but current technology limits their use to only a few dozen wavelengths. One approach to circumvent this limitation is to arrange processing nodes (PNs) on fibers in groups and spatially separating those clusters. Grouping those clusters together in a higher level structure, or hierarchy, allows any node to communicate with any other in a large network while using only a few wavelengths. One potential hierarchy presented previously [1], Hierarchical Optical Ring Interconnection Network (HORN), uses a clustered hierarchical approach in which clusters consist of a set of PEs optically interconnected and these clusters are optically connected by higher level rings. As such, a highly scalable architecture is achieved, overcoming the fixed number of available wavelengths through spatial reuse of t..
