Abstract

In this thesis, we propose two methods of traffic grooming to effectively and efficiently utilizing the fiber bandwidth. The first method deals with sharing of time-slots in a wavelength. The second method involves further division of each time-slot in a wavelength into mini-slots. For each method, a corresponding optical data transport network architecture enabling the respective traffic grooming has also been proposed; they are namely the shared time-slot time division multiplexing (TDM) wavelength optical WDM network and the mini-slot TDM wavelength optical network. The two proposed optical networks are technically feasible to implement based on the results of our analysis and the availability of the network components. In addition, we have also proposed an analytical model for TDM wavelength optical networks with OTSIs and without WC using the partition based approach with two objectives: (1) to validate the simulation results of this network, and (2) to calculate the average network blocking probabilities of this network.
