A Blog of the ZHAW Zurich University of Applied Sciences
Following on from our 2nd meeting, the Swiss OpenStack user group met on 24th of April at the University of Bern.It was an excellent event with many attention grabbing presentations! A big thanks goes out to the sponsors…
Last Friday Philipp from the ICCLab gave a presentation about SDN and OpenFlow to ZHAW master students. The big difference is that the average age of the students is higher and all of them are working for many years in the field of IT. Furthermore, most of them have a leading position in their daily work. The content of the presentation is not that detailed an covers basically the two whitepapers from the ONF and openflowhub.org about SDN and OpenFlow. We also talked about the available products in the field of OpenFlow controllers and why SDN in general is such an important thing for the datacenter providers, ISP’s or Carrier Ethernet.
If you are also interested in SDN architecture and want to use the OpenFlow specification for it, a good starting point is the tutorial on openflow.org. OpenFlow has its roots at Stanford University and provides the communication between the data- and the control-plane in a SDN based network architecture. In this article we will show you how to setup a system that implements a learning switch using the OpenFlow specification.
Software-Defined Networking (SDN) is an architecture for computer networking. The overall key concept for SDN-based architecture is to define a control plane and a data plane. The control plane is represented as a server or appliance that takes the accountability for the communication between the business applications and the data plane.
Luke Gorrie, founder of http://www.snabb.co/, pioneer, and serial make-it-happener (call it entrepreneur) in the network technology domain, came over to visit the ICCLab to discuss future research and engineering domains of Software Defined Networking (SDN).
