LATIN ROUTERS, DESIGN AND IMPLEMENTATION

Consider an optical system where the available bandwidth is divided into F frequency bands. The connectivity of an N x N wavelength routing device, or an all optical network with passive wavelength routing can be specified by an N x N matrix S. where the (i, j)th element, S(i, j), is the set of wavelengths connecting input i to output j. When the matrix S is a latin square, we call the device a Latin Router. We present a class of designs for very large Latin Routers from a relatively small number of components. The designs use a minimal number of interconnections and can be implemented distributively.
