A ew Centralized Multicast Wavelength Allocation Algorithm in Optical Fiber etwork
Abstract. Wavelength assignment is a widely research object and especially in optical networks. The centralized algorithm has been proposed in this paper and there are two scenarios for our algorithm. The main effect and improvement in the algorithm is to save network capacity by decreasing network capacity after each wavelength assignment. The term network capacity and network capacity decreas...
متن کاملA New Multicast Wavelength Assignment Algorithm in Wavelength-Converted Optical Networks
In this paper, we propose a new multicast wavelength assignment algorithm called NGWA with complexity of O(N), where N is the number of nodes on a multicast tree. The whole procedure of NGWA algorithm is separated into two phases: the partial wavelength assignment phase and the complete wavelength assignment phase. It tries to minimize the total number of wavelength conversions of the multicast...
متن کاملOperator-probability Adaptation in a Genetic-algorithm/Heuristic Hybrid for Optical Network Wavelength Allocation
Operator-probability adaptation in a genetic-algorithm/ heuristic hybrid for minimum cost routing and wavelength allocation of multi-wavelength all-optical transport networks is described. The hybrid algorithm uses an object-oriented representation of networks, and incorporates four operators: path mutation, single-point crossover, reroute and shift-out. The adaptation algorithm is based on tha...
متن کاملA Dynamic RWA Algorithm in a Wavelength-Routed All-Optical Network with Wavelength Converters
Existing research demonstrated that an effective Routing and Wavelength Assignment (RWA) scheme and a wavelength converter placement algorithm are the two primary vehicles for improving the blocking performance in a wavelength-routed all-optical network. However, these issues have largely been investigated separately, in particular, the RWA has seldom considered the existence of wavelength conv...
متن کاملA Dynamic RWA Algorithm in a Wavelength - Routed All - Optical Network with Wavelength Converters 1
have largely been investigated separately, in particular, the RWA has seldom considered the existence of wavelength converters. In this paper, we argue perhaps for the first time, that an effective RWA algorithm needs to take into account the presence of wavelength conversion as the later is usually done at much earlier stage during the capacity planning. We proceed to show that existing dynami...
