Global seamless network demonstrator: a comprehensive ASON/GMPLS testbed
ABSTRACT 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.
Conference Paper: SAN extension testbed within the global seamless networks demonstrator[Show abstract] [Hide abstract]
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 demandTestbeds and Research Infrastructures for the Development of Networks and Communities, 2006.

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.IEICE Transactions on Communications 08/2007; E90B(8).

ABSTRACT: This article presents first the history of the optical fiber transport networks, from the introduction of the first high capacity systems in the 1990s to the 10 Gbit/s per channel WDM (Wavelength Division Multiplexing) systems deployed today, and the tremendous evolution of performance within this period. The effects of propagation in optical fibers and their consequences for optical system engineering, the architecture of today's optical transport networks, the choices made in France are recalled. We then have a look at the future of optical transport networks from an operator's point of view: the expected evolutions in terms of transmission system capacity and network architecture are presented. We conclude that capacity, transparency, and agility are the main drivers of the evolution of optical fiber transport systems and networks and that a lot of changes have yet to be expected in these domains during the next decade.
