ABSTRACT:
A controller at each node of a mesh type grid network of single mode optical fibers implements a switching algorithm which passes a given message to four neighboring nodes only once to avoid flooding the network. If a given wavelength is present on more than one input, the first to arrive is passed and the second to arrive is blocked. The network is configured to provide a large number of redundant paths, ensuring a high probability that a path will exist even in the face of significant network damage.
