Elastic optical networking that enables flexible spectrum resource allocation and bitrate/distance-adaptive modulation is one of the hot trends in optical networks to cope with both legacy low-bitrate services and emerging new bandwidth-abundant super-channel services. This paper evaluates spectrum utilization and regenerating spectrum requirement in regeneration capable elastic optical networks with...
The standard core GMPLS networks consist of two layers, Fiber Switch Capable (FSC) and Wavelength Switch Capable (LSC). To extend the core switch capacity, code switch capable (CSC) layer has been added. The CSC layer, however, induces the complexity of the networks. In this paper, we propose a novel scheme of two-dimensional (2-D) optical code label for core GMPLS networks. In our proposal, the LSC...
