Wavelength Division Multiple Access Ring - Virtual Topology on a Simple Ring Network -

摘要

In this paper, Wavelength Division multiple ac- cess (WDM) ring is proposed for interconnection in workstation clusters or parallel machines. This network consists of ring con- nected routers each of which selectively passes signals addressed in some particular wavelengths. Other wavelengths are once con- verted to electric signals, and re-transmitted being addressed in different wavelengths. Wavelengths are assigned to divisors of the number of nodes in the system. Using the regular WDM ring with imaginary nodes, the diameter and average distance are reduced even if the number of nodes has few divisors.
