Open Networking
The testbed at Saarland Informatics Campus aims to provide an environment for testing new networking technologies. In particular, Software Defined Networks and Open Source network software are our main field of research. As part of the Telecommunications Lab at Saarland Informatics Campus, we focus on transport of multimedia content and control signals and how multimedia internet applications as well as cyber-physical systems can be supported.
The testbed features wide-area-network (WAN) characteristics, as remote sites all across the globe are connected to it via VPN technology.
In order to create realistic and diverse environments, we are open for further partners to extend our network. For more information about our projects, or in case you want to join us, please send us a message.
Software:
Ubuntu 16.04, Open vSwitch, Floodlight, Ryu, Node.js, SaltStack
Hardware:
HP ProCurve 2920, Custom VPN Softswitch
