Abstract/Summary:
As the data traffic on the Internet increases explosively, traditional Optical-Electrical-Optical (O-E-O) based optical networks will soon meet the bandwidth starvation due to limited speed of O-E-O conversion. All-optical networks (AON) enabled with Wavelength-Division Multiplexing (WDM) are the promising solution for next generation networks. This dissertation studies the problems of providing robust differentiated-services for sub-wavelength switching in wavelength-routed AON with uncertain link state information.;Firstly, Segment-based Robust Fast Optical resource Reservation and signaling Protocol (S-RFORP) is proposed to support the multi-granular lightpath setup in wavelength routed all-optical networks. S-RFORP employs segment-based parallel operation to minimize the lightpath setup delay, and reservation blocking recovery control to minimize the lightpath setup blocking. Secondly, Differentiated Robust Adaptive Scheduled Optical Burst Switching (DRAS-OBS) is proposed to provide proportional service differentiation while maximizing the overall network throughput. Finally, the Synchronization-Aware switch configuration control is proposed to deal with the uncertain link state information that incurs holding-time synchronization error in large all-optical networks.
