This article reports on the continuous activities of Deutsche Telekom in setting up comprehensive ASON/GMPLS network demonstrators. The goal is to enable practical evaluations and early experiences with prototype implementations related to new standards and specifications from ITU-T, IETF, and OIF. Evolving from the GSN Demonstrator toward the current GSN+ Demonstrator configuration, this field testbed comprises ASON/GMPLS-based backbone network domains, as well as key client networks such as IP, Ethernet (metro and access networks), storage area networks, and broadband video applications to exemplify the wide range of network functions enabled by these new technologies. These ASON/GMPLS demonstrator activities were embedded in the OIF World Interoperability Tests and Demonstration in 2004, and are linked with the German national (VIOLA) and pan-European (MUPBED) project activities ensuring the highest level of interoperable implementations.

    ABSTRACT: A demonstrator has been installed in a field environment in Deutsche Telekom's project `global seamless networks' (GSN+). Three local storage area networks (SAN) in different laboratories are linked together via fibers with lengths of 80 and 860 km. This testbed within the GSN+ demonstrator is used for testing SAN extension and demonstrating new SAN services. The SAN services are based on the fibre channel over SDH protocol. The SDH network connection can be initiated by the customer, i.e., all the services are SAN extension on demand

    ABSTRACT: An integration of the access/backbone network is expected to become indispensable in the future. We analyze the current and future optical networks and we describe the promising technologies. GMPLS architecture in backbone networks and WDM PON architecture in access networks will play the most important roles. We overview recent studies on the access/backbone integrated network to achieve guaranteed QoS. We also describe the developed system architecture as a milestone toward the access/backbone integrated network.

    ABSTRACT: Optical Switching Networks describes all the major switching paradigms developed for modern optical networks, discussing their operation, advantages, disadvantages and implementation. Following a review of the evolution of optical WDM networks, an overview of the future trends out. The latest developments in optical access, local, metropolitan, and wide area networks are covered, including detailed technical descriptions of generalized multiprotocol label switching, waveband switching, photonic slot routing, optical flow, burst and packet switching. The convergence of optical and wireless access networks is also discussed, as are the IEEE 802.17 Resilient Packet Ring and IEEE 802.3ah Ethernet passive optical network standards and their WDM upgraded derivatives. The feasibility, challenges and potential of next-generation optical networks are described in a survey of state-of-the-art optical networking testbeds. Animations showing how the key optical switching techniques work are available via the web, as are lecture slides ( © Cambridge University Press 2008 and Cambridge University Press, 2010.
