Network Virtualization (NV) realizes the decoupling of network infrastructure and network services. With the emergence of the Software Defined Network (SDN), it is easier to implement NV supporting dynamic heterogeneous underlay network. In this paper, we present and experimentally validate an Optical Network Virtualization (ONV) architecture based on OpenVirteX (OVX) supporting bandwidth on demand...
Aiming at providing united control of multi-domain optical networks orchestration, we design the Federated Platform based on Open Network Operating System (ONOS). Our implementation includes adding and extending modules in ONOS to provide the global view of multi-domain networks and support cross-domain end-to-end services by communicating with the individual domain controllers through RESTCONF protocol...
We proposed a size-scalable and cost-efficient OXC architecture using limited port fine-granularity bandwidth-variable wavelength selective switches and waveband selective switches for elastic optical network, as well as a routing and spectrum allocation scheme.
