Elastic Optical Networks (EON), which are able to allocate an appropriate optical spectrum range and modulation format to an optical path according to the client (e.g. IP) traffic demand and path attributes (e.g., physical length or optical impairments), have been proposed to more efficiently utilize network spectrum resources. A control ...Download Now
In this paper, for the first time, the authors experimentally demonstrate an OpenFlow-controlled Elastic Optical Network (EON) employing a flexible transmitter/receiver. The flexible transmitter can switch the symbol rate and modulation format of the optical signal without modifying the hardware, and the flexible receiver can automatically detect different modulation formats ...Download Now
In today's commercial IP/optical multi-layer networks, different layers are separately operated without dynamic interaction, which leads to low network efficiency, high OPEX and CAPEX, as well as long processing latency for path provisioning and restoration. Despite a decade of development and standardization efforts, with three different interconnection models (i.e. peer, ...Download Now
OpenFlow, as a promising control plane technique for a software-defined network, has been attracting much attention from both academia and industry in recent years. In, an OpenFlow-based control plane for a single domain Wavelength Switched Optical Network (WSON) has been experimentally presented. However, to the best of the authors' knowledge, ...Download Now
