SDN fundamentals & techniques

Course contents

This course covers the principles of legacy routing and Software-Defined Networking (SDN), an important cornerstone of the 5G and beyond network systems.

The course envelops theoretical and practical aspects of SDN, showcasing the different existing SDN protocols and controllers, with focus on ONOS and OpenFlow as SDN controller and SDN protocol, respectively.

The student will be shown the utilisation of Linux namespace and Linux containers, as well as the installation and configuration of Mininet and its integration with the physical network.

The network troubleshooting by leveraging the Wireshark tool will be covered. Using the latter, the student will be able to leverage OpenFlow filters integrated with Wireshark for capturing different OpenFlow messages exchanged in the network.

Finally, on this course, the student will be able to develop an SDN orchestrator that leverages the SDN technology for enabling the Service Function Chaining (SFC) concept.
