Paper Abstract

We propose solution techniques for the problem of determining how many access rings are required, which locations should be served by each ring, and to which hub each access ring should be connected. We take into account the cost per mile of the optical fiber used to form the Wavelength Division Multiplexing (WDM) rings, the cost associated with exchanging traffic, the capacity of the WDM rings, the set of demands for wavelengths and the distances between locations. These techniques are based on `joining' algorithms used in statistical clustering. Initially, each location is assumed to be served by its own WDM ring. Using a particular metric to determine candidate pairs of rings, an iterative procedure is used to combine locations served by two rings onto a single ring. We compare different metrics in order to evaluate their performance on a study network based on data from a major U.S. city.
