Multi-adaptive S-BVT for software defined optical networks

In this paper, we present an S-BVT architecture and its building blocks for multi-adaptive optical transmission in software defined networks (SDNs). We particularly focus on the S-BVT design options, based on multicarrier modulation (MCM), with the ability of generating multiple bands and flows. This allows to adaptively vary the rate, format, bandwidth and reach with fine granularity and large scalability. To fully exploit the versatility, programmability and multiple functionalities of the S-BVT, its integration in an SDN is envisioned, targeting an optimal usage of the network resources. Furthermore, related results obtained within the ADRENALINE testbed and in the framework of the EU-Japan STRAUSS project will be reported.
