Towards Digital Optical Networks - Towards digital Optical Networks
Proceedings of 2005 7th International Conference Transparent Optical Networks 2005., 1Co-Authors: Ioannis Tomkos, Anna TzanakakiAbstract:Technical breakthroughs in Optical communications research are expected to further accelerate the realization of transparent Optical Networks to offer increased transmission bandwidth, integrated transmission and switching capabilities and Optical signal processing functionality. This progress provides scalable, transparent and flexible end-to-end solutions in the metropolitan and access Networks. These advanced Optical network infrastructures will enable accessibility of new services and applications to the end user offering full access to the global information network with improved system performance and reduced cost. The primary objective of the EU COST 291 action "Towards Digital Optical Networks" is to focus on novel network concepts and architectures exploiting the features and properties of photonic technologies, to enable future telecommunications Networks. It is aiming to propose a new generation of Optical systems and Networks that will accommodate the unpredictable and growing size of traffic demands over global distances requiring an agile communication grid supporting quality of services. This advanced photonic infrastructure will employ dense wavelength division multiplexing technologies for signal transmission and routing, Optical signal processing and dynamic impairment management to eliminate the limitations of the analogue nature of traditional Optical Networks, and Optical packet and/or burst switching to provide fine bandwidth granularity, network efficiency and flexibility. The presentation will outline resent research advancements towards the realization of digital Optical Networks and will present some key activities undertaken within the framework of COST 291 project.

control plane design in multidomain multilayer Optical Networks
IEEE Communications Magazine, 2008Co-Authors: Nasir Ghani, Qing Liu, Driss Benhaddou, Nageswara S V Rao, Tom LehmanAbstract:As Optical Networks proliferate, there is a growing need to address distributed multi- domain provisioning. Although multi-domain operation has been well-studied in packet/cell- switching Networks, the multilayer (granularity) circuit-switched nature of modern Optical Networks presents a unique set of challenges. This survey addresses control plane design for such heterogeneous infrastructures and describes new challenges in the areas of state dissemination, path computation, and survivability. Sample results from a recent study also are presented.

Protection strategies in metro Optical Networks
Proceedings of SPIE, 2002Co-Authors: Nasir GhaniAbstract:Optical technology has brought about altogether new paradigms in the networking field and created an immense momentum in the telecommunications market. Optical component technologies are now enabling the development and deployment of advanced, Optical solutions for many networking needs. Overall, there have been some major trends towards Optical Networks comprising ring/mesh-routed topologies, and connection management intelligence. One of the key challenges to the evolving Optical transport network (OTN) is network survivability; how traffic can be protected in OTN with survivability levels equivalent to those achieved in todays SONET/SDH Networks. In this article, we focus on metro Optical network protection. We begin with an overview of metro Optical transport network survivability requirements, followed by an analysis of various network protection mechanisms and how these mechanisms may evolve to support the development of metro Optical Networks. The benefits of using ring protection scheme in metro Optical Networks are demonstrated.

survivability in Optical Networks
IEEE Network, 2000Co-Authors: Dongyun Zhou, Suresh SubramaniamAbstract:Survivability, the ability of a network to withstand and recover from failures, is one of the most important requirements of Networks. Its importance is magnified in fiber optic Networks with throughputs on the order of gigabits and terabits per second. This article takes a look at the techniques used to achieve survivability in traditional Optical Networks, and how those techniques are evolving to make next-generation WDM Networks survivable.
