Physically Aware Agile Optical Networks

With the development of new laser sources, fiber§amplifiers, and other optical components, optical§communication systems have undergone enormous growth§and evolution in recent decades. The current trend of§optical networking is to move towards dynamic,§all-optical networks. In all-optical networks,§information signals are transmitted from source to§destination totally in the optical domain, without§the usual optical-electrical-optical conversions at§intermediate nodes. New challenges and opportunities§emerge in different layers of the optical network§architecture in this transition process. This book§explores several interesting topics in both the§physical layer and the network layer of all-optical§networks. Our studies examine physical impairments§which can adversely influence network performance.§Both novel proactive and reactive approaches are§proposed to improve network performance and provide§quality of service (QoS) for users. The proposed§methods and algorithms can be especially useful to§professionals, students, and researchers working in§the field of optical communications.
