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.

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.
