Abstract:

Optical networks with Wavelength Division Multiplexing (WDM) technology provide huge bandwidth to meet the ever-increasing traffic demand of the next generation Internet. But the high-speed nature of WDM networks also makes the network more vulnerable to failures. Even a single network failure for a very short duration can result in enormous loss of data. In this thesis, we concentrate on designing a survivable WDM network. In essence, survivability concerns two important aspects, fast fault detection and localization, and fast fault recovery. We first study fast fault detection and locali

Abstract:

Wavelength division multiplexing passive optical network (WDM-PON) can meet growing bandwidth demand in access network by providing high bandwidth to the end users. Failure in the access network is becoming critical as a large volume of traffic might be affected. Therefore, an effective supervision mechanism to detect and localize the fault is required to shorten the service interruption time. Meanwhile, open access provides a certain freedom for end users to choose the service and hence boosts competition among service/network providers. On the other hand, to offer open access in WDM-PON coul

Although, their low propagation loss, and low dispersion, they suffers from high power losses at sharp bends.

Wavelength division multiplexed (WDM) optical networks are rapidly becoming the technology of choice in network infrastructure and next-generation Internet architectures. WDM networks have the potential to provide unprecedented bandwidth, reduce processing cost, achieve protocol transparency, and enable efficient failure handling. This dissertation addresses the important issues of improving the performance and enhancing the reliability of WDM networks as well as modeling and evaluating the performance of these networks. Optical wavelength conversion is one of the emerging WDM enabling technol

Abstract:

<p>Many applications and telecommunications services in futurehigh-speed networks will require some form of multipointcommunication. The problems associated with providing network support formultipoint communication have been widely studied within anumber of different networking contexts.As current network technologies evolve to an all-optical, largely passive infrastructure, these problems takeon new significance and raise a number of challenging issuesthat require novel solutions.<p>We consider the problem of supporting multipoint communication at the media access control (MAC) layer of broa
