NetCat: Cross-plane Approach for Dynamic, Distributed Service Provisioning in a GMPLS Enabled Optical Testbed

Your library or personal account may give you access


Dynamic service provisioning is expected to a key feature of next-generation optical networks. The increasing use of wavelength multiplexing (WDM) infrastructures due to Internet traffic is expected to play a crucial role in the flexible, low-cost networking needed for the inherent dynamism of future data services. While the main evolution of current infrastructures is optical intelligence (automated functions in the network), principally through distributed approaches such as the Generalized Multi-Protocol Label Switching (GMPLS) framework, services, mainly based on the Internet Protocol (IP), are also evolving from centralized to distributed. In this work, we group traditional telecommunications services with centralized control (i.e. network operator) as ‘centralized services’, whereas ‘distributed services’ are those user-defined or managed, such as Grids or customer-empowered applications [1, 2].
