A Study on Effective Algorithm Design Methods for WDM Optical Network

WDM 광 통신망에서 망의 효율적인 알고리즘 설계방법에 관한 연구

WDM is a very promisinig technique for the realization of future All-Optical networks. WDM gives an advantage of high rate transmission without delay for Electronic/optical conversion. But the available number of wavelengths is limited by technical restriction. so the efficient optical path routing and wavelength assignment is needed. this paper is concerned with the efficient design of WDM optical transport networks. RWA assumes that the connection demands between node pairs are given. the objective of RWA is to minimize the number of wavelengths. these design consider the static routing and wavelength assignment in the network of arbitrary topology. To solve these problems, this paper proposes some heuristic algorithms.
