Abstract

Advancement in optical network elements, such as optical cross-connects, optical transmitters and receivers, wavelength converters, and low attenuation fibers, enabled the development of high performance local area and wide area optical networks. Optical WDM networks provide an excellent transmission medium for current as well as future voice and data traffic, streaming media, and high performance and grid computing needs. Rearrangeability is one of the compelling characteristics of Wavelength Division Multiplexed (WDM) Optical networks that allow network operators to rearrange the networks in response to changing traffic demands and element failures in order to provide improved network performance. Under changing traffic flows and abhorrent network conditions reconfiguration is an ongoing process. The available approaches are not able to handle extreme load conditions, traffic bursts and element failures and, so far, the solutions proposed cover only limited aspects of the complex and challenging problem of automated reconfiguration. Thus the aim of this study was to design and implement an adaptive topology reconfiguration mechanism that performs network reconfigurations at run time by utilizing multiple approaches, reconfigures topology through an approach that incurs the least cost, and would be able to overcome the limitations of the existing solutions under data flooding and link failure scenarios.
