Minimizing Drop Cost for SONET / WDMNetworks with 18 Wavelength
SONET/WDM networks using wavelength add-drop multiplexing can be constructed using certain graph decompositions used to form a `grooming', consisting of unions of certain primitive rings. The existence of such decompositions when every pair of sites employs no more than 1 8 of the wavelength capacity is determined , with few possible exceptions, when the ring size is a multiple of four.

متن کاملMinimizing SONET ADMs in Unidirectional WDM Rings with Grooming Ratio Seven
In order to reduce the number of add-drop multiplexers (ADMs) in SONET/WDM networks using wavelength add-drop multiplexing, certain graph decompositions can be used to form a “grooming” that specifies the assignment of traffic to wavelengths. When traffic among nodes is all-to-all and uniform, the drop cost of such a decomposition is the sum, over all graphs in the decomposition, of the number ...
متن کاملLocal Search Heuristics for Cost Reduction in WDM Bidirectional Rings
In this note Local Search heuristics are proposed for the problem of minimizing the number of expensive Add-Drop Multiplexers in a SONET or SDH optical network ring, while respecting the constraints given by the overall number of fibers and the number of wavelengths that can carry separate information on a fiber.
