  Abstract

This thesis describes two wavelength allocation algorithms applied to OMS (Optical Multiplex Section) or OCh (Optical Channel) SPRING (Shared Protection Ring) and compares their characteristics by simulations.
Two wavelength allocation algorithms are optimal algorithm and nonblocking algorithm applicable on SPRING WDM networks. In particular, when a node is added in previous ring network, how to work for each algorithm is considered. The optimal algorithm is better than nonblocking for most of comparisons. Nonblocking algorithm has an important advantage, though. Nonblocking algorithm has no wavelength connection or allocation to reconfigure some previous connections.
