Demo: Resilient Integration of Distributed High-Performance Zones into the BelWue Network Using OpenFlow

The Internet service provider (ISP) BelWue interconnects higher education and research institutions in Baden-Wuerttemberg, Germany. Its 10 Gb/s backbone among university campuses has been augmented with an additional optical 100~Gb/s high-speed network called NeIF. The bwNET100G+ project sets up special high-performance zones (HPZ) at a few university campuses and seeks for cost-efficient interconnection over the NeIF and integration into the legacy infrastructure. We propose for that purpose SDN-NeIF, a software-defined network architecture leveraging OpenFlow and iBGP. The demo illustrates this concept for three university locations with a special focus on resiliency. It leverages a virtualized testbed consisting of four desktop PCs and three consumer switches. The demo validates the SDN-NeIF architecture and serves as a first proof-of-concept.
