What is SDN? What is OpenFlow?
Basically SDN is about programming network
devices like switches and routers from a central
point known as the SDN Controller. The
controller uses a common protocol - OpenFlow
when communicating to the devices.
We'll start by looking at OpenFlow traffic, the
initial stages of communications between
OpenFlow enabled switches and the SDN
controller, see examples of OpenFlow comms using
applications on the SDN controller for
configuring the switch for flows, and
demonstrations showing how a switch processes
traffic based on OpenFlow programming and
standard switch operations - this is known as
Everyone is encouraged to bring their laptop
with Wireshark installed (min v2.0.0), download
the provided trace file, and follow Jeff viewing
OpenFlow packets. You will use built-in
Wireshark OpenFlow display filters and create
color definitions to assist in recognizing
OpenFlow traffic quicker.
