Abstract
Circle constructions can find many applications in the system design phase of WDM ring networks to optimize system performance, while still efficiently utilizing the network resources under consideration (e.g., total number of wavelengths or transceivers). In this letter, we present a series of matrix‐based circle‐construction algorithms to minimize the number of required wavelengths in both unidirectional and bidirectional rings under an arbitrary traffic pattern. A Matlab implementation of the algorithms can effectively generate the optimum design solution in terms of the total cost on wavelengths. Thus, it ensures that the channel bandwidth and I/O capacity in the WDM rings are utilized most efficiently. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 221–225, 2001.
