With the development of new laser sources, fiberamplifiers, and other optical components, opticalcommunication systems have undergone enormous growthand evolution in recent decades. The current trend ofoptical networking is to move towards dynamic,all-optical networks. In all-optical networks,information signals are transmitted from source todestination totally in the optical domain, withoutthe usual optical-electrical-optical conversions atintermediate nodes. New challenges and opportunitiesemerge in different layers of the optical networkarchitecture in this transition process. This bookexplores several interesting topics in both thephysical layer and the network layer of all-opticalnetworks. Our studies examine physical impairmentswhich can adversely influence network performance.Both novel proactive and reactive approaches areproposed to improve network performance and providequality of service (QoS) for users. The proposedmethods and algorithms can be especially useful toprofessionals, students, and researchers working inthe field of optical communications.
