“…We adopted the shared by node model [9], that is the converters placed at a node can be shared by any lightpaths that pass through this node. Now we formally define the problem addressed in this paper as follows: given the network G and a set of traffic demand D=(l 1 [10], so this algorithm A never exists and OPWB is NP-hard.…”

“…Wavelength division multiplexing (WDM) [1][2] divides the bandwidth of an optical fibre into multiple wavelength channels so that multiple users can transmit data at distinct wavelengths through the same fibre concurrently. Since all-optical WDM networks can provide communication service with huge bandwidth and low latency, such networks are considered as candidates for the next generation wide-area networks which are required to meet the increasing traffic demand in the foreseeable future.…”

Abstract. In this paper, we study the following problem. Given the network topology and traffic demand, determine how a minimum set of wavelength converters should be placed to ensure that the number of wavelengths needed will not exceed a given bound L+u, where L is the maximum link load in the network and u is a parameter defined by the network designer to reflect the overall availability of wavelength resources. This problem, however, is proved to be NP-hard. Hence we develop an efficient heuristic algorithm and extensive theoretical and experimental studies are carried out to verify the effectiveness and performance of the algorithm.
