چکیده
A survey of recent literature on all optical networking is presented. Starting from multiplexing techniques and topological features, network design and performance issues are reviewed. Particular attention is devoted to Wavelength Division Multiplexing (WDM) networks. Static and dynamic solutions of the routing and wavelength assignment (RWA) problem are considered. Issues of current research are summarized.

Passive optical network (PON) supported networking
In this editorial, we first set the context for the subject matter of this special issue on passive optical network (PON) supported networking. This context includes a discussion of optical networking in all segments of a global communication network and the emphasis of the importance of PONs in the access network as well as their role supporting other communication network technologies. We fol...
متن کاملOptical networks - the electro-optic reality
A general overview of the current status and future trends in optical networking is given. Special attention is given to the coexistence of optical and electronic technologies in telecommunications networks. After reviewing the advantages of both technologies, their use in different network areas is discussed. A critical survey of current and new transport technologies in optical core and metro...
متن کاملAll-Optical Networking - Evolution, Benefits, Challenges, and Future Vision
While all-optical networking had its origins in the research community a quarter of a century ago, the realization of the vision has not had a straight trajectory. The original goal of the all-optical network was based on keeping the data signals entirely in the optical domain from source to destination to eliminate the so-called electronic bottleneck, and to allow arbitrary signal formats, bit...
متن کاملA comparison of optical buffering technologies
We describe the practical and fundamental limitations of the more prominent optical buffering approaches. The architectural implementation and needs of an optical packet switch are used as a foundation for the study. We also present initial results for a buffered, all-optical, 40 Gb/s packet switch. c © 2007 Elsevier B.V. All rights reserved.
متن کاملTowards Scalable, Contention-free Data Center Networking with All-Optical Switching Fabric
We propose a scalable all-optical switching architecture towards contention-free data center networking. The arrayed-waveguide-grating router (AWGR) based switching fabric utilizes wavelength parallelism to alleviate contention, to reduce latency, and to improve scalability. ©2010 Optical Society of America OCIS codes: (060.4250) Networks; (200.6715) Switching
متن کاملOptical Network Models and their Application to Software-Defined Network Management
Software-defined networking is finding its way into optical networks. Here, it promises a simplification and unification of network management for optical networks allowing automation of operational tasks despite the highly diverse and vendor-specific commercial systems and the complexity and analog nature of optical transmission. A fundamental component for software-defined optical networking ...
