“…The former, traditional adaptive routing algorithms (such as those mentioned above) usually select their routes based on maximizing the number of free wavelengths and do not explicitly consider the hop length. While this is not good for wavelength conversion networks ( [8], [9] present new adaptive routing algorithms for full wavelength conversion networks), it usually can lead to better results than static approaches in WS networks. In fact, without wavelength conversion, the route with more free wavelengths also usually has shorter hop length; the probability that a longer route has more free wavelengths is much smaller by comparison with shorter routes [10].…”

Abstract-Management is a critical issue in optical networks. Highly impacting in management, routing in optical networks, is often decoupled into both the path selection and the wavelength assignment problems. In the former, shortest path based approaches are often applied to compute paths. Although such approaches offer advantages in terms of network loading, they are restricted by the fact, that routes are selected without taking into account parameters pertaining to any explicit and desired service guarantees. Thus, the wavelength assignment process may assign a non-optimal wavelength with respect to incoming traffic requirements and any associated quality of service specifications. This paper addresses the lightpath selection problem by proposing a novel route selection scheme where routes are determined based upon the twin criteria of minimizing the number of hops and balancing the network load, resulting in a reduction in both network congestion and blocking probability.

“…To implement traffic engineering over a topology schedule, we define a traffic schedule, which determines which traffic (e.g., packets) will be sent over which link and at which time. We further note that a traffic schedule could be either oblivious (as oblivious routing [29]) or adaptive (as adaptive routing [30]). For example, Sirius [10] uses oblivious routing over oblivious topology while RotorNet [12] and Opera [15] uses adaptive routing over oblivious topology.…”

“…A comprehensive survey of the existing results can be found in [13]. While most of the previous work has been done for fixed routing schemes, alternative-path routing schemes [34,35,74], dynamic routing schemes [77,78], and the more general case under heterogeneous traffic [79] have also been analyzed.…”

First of all, I would like to thank my supervisor, Dr Xiao Gaoxi, for his continuous support, guidance and encouragement. I enjoy each discussion with him. He always shares his fruitful experiences and knowledge with me. During my study in Nanyang Technological University, Dr Xiao Gaoxi let me know how to do research, how to keep enthusiasm, dedication to excellence, and careful attention to details. I feel very proud to be given this opportunity to study under his supervision. Without his help, this thesis would not have been made.
