Frequency/time assignment algorithm in optical networks

Yao Gao, University of Massachusetts Amherst

Abstract

The introduction of optical technology has brought forth the age of high speed communications. Emerging high bandwidth applications, coupled with existing applications are providing a strong push for the realization of integrated high speed networks. The rapid development of lightwave technology offers the network architect several terahertz of bandwidth in a single optical fiber. However, we do not expect to see the implementation of all-optical networks in the near future, so we are forced to consider hybrid networks that employ a combination of both lightwave and electronic technologies. One approach, called wavelength division multiplexing (WDM), could provide a large number of high speed channels on a single optical fiber by independently modulating different wavelengths of light in the spectrum passed by the fiber. This dissertation presents a new approach to the emerging areas of satellite communication and high speed local area networks. These areas generated new and challenging research problems that have to be solved for efficient system operation. For the satellite cluster with optical intersatellite links, the first slot assignment algorithm is developed. The first approach for the time-wavelength allocation algorithms that incorporate the unique aspects of WDM communication for the single star based and multiple star based systems is also presented in this dissertation. The virtual topology design in multihop lightwave networks is investigated to minimize the number of wavelengths in the system.
