| Abstract | The diffusion of Internet in society both for simple users and enterprises through the rise of applications and business models has resulted in a vast volume of traffic that needs to be transferred across the globe in a fast, reliable and secure way. Millions of fixed and mobile users produce and consume information, especially due to the recent increase of smart phones and tablets technology on the one hand and the fast growth of services like video, high definition TV and social networking on the other. Speed, reliability and minimal delay have been some of the key requirements for service delivery across the years of Information and Communications Technology (ICT) evolution. Current and future services take these requirements to a new level, not only because of the huge number of users and end-devices, but also due to the special requirements they have. To support these, new types of infrastructures have been developed such as interconnected Data Centers through high speed networks offering cloud-based services. Optical networks through recent technology advancements offer a very promising solution to support not only traditional telecommunications applications but all the new applications emerging in the context of cloud computing, due to the huge bandwidth they offer, the long transmission distances and several other characteristics including flexibility, cost and energy efficiency. Apart from the evolution of network equipment technology offering among others improved physical layer performance across long distances, regeneration capabilities, low energy consumption and fast recovery, significant effort is required on the track of network design and operation. The work presented in this thesis concentrates in optical networking in support of traditional telecommunications and more advanced cloud computing services. More specifically it addresses some key optical network design and provisioning problems and aims at identifying efficient solutions to mitigate them. A core optical network able to efficiently accommodate traffic with special characteristics and requirements is the basis of every problem we address. In this context, physical layer impairments and their consideration in route selection, resilience against link failures, energy efficiency and a special case of service deployment in converged optical networks and Data Center (DC) infrastructures are the four main areas that this work focuses on through the formulation and solution of associated problems. Core optical networks are commonly based on mesh topologies that accommodate |
