Traffic grooming and rerouting in multi-layer WDM network

Abstract : High-performance transport networks are expected to support applications with various types of traffic, e.g., permanent, scheduled, bursty, and noisy traffic flows. Since high-performance networks usually employ optical network infrastructures, and since most applications require sub-wavelength bandwidth, several streams are usually groomed on the same wavelength. It is therefore important that such networks are designed in an optimal way in terms of cost while efficiently supporting these types of traffic. This thesis deals with the design and analysis of optical networks allowing for traffic engineering including grooming and rerouting functionalities. Both deterministic and random traffic scenarios are considered. As a first step, optimal as well as accurate heuristic approaches are developed for network design and operation under deterministic traffic conditions. As a second step, under random traffic conditions, the dynamic routing and grooming problem is considered subject to the availability of free network resources. Several algorithms are developed to facilitate this provisioning problem. At last, rerouting techniques are addressed. We investigate different rerouting strategies and their implementation in order to enhance network efficiency under specific traffic scenarios.
