Laboratory assessment nº 1: The current laboratorial class aims to individually test some practical knowledge about how to deploy mininet topology, configure control rules locally at the network switch, extending mininet topology via a script with shell commands, and network testing.

Laboratory session on using the Northbound REST API between a top-level application and

the Ryu SDN controller. Students interact with the controller through curl commands that

send HTTP messages to the REST API to manage a Mininet-emulated network topology. The

lab also extends the Ryu REST API to support additional functionality for VLAN

management within the network.

The current laboratorial lecture taught how to deploy an SDN-based networked system formed by a single SDN controller (i.e. Ryu), one software-based OpenvSwitch (OVS), and several hosts interconnected through the software-based switch OVS. The current lecture also taught how the OpenFlow (v1.0) protocol allows the Ryu SDN controller to control in distinct ways the switch OVS and consequently the network operation. Finally, the applicants learn how to make some code changes in the controller for blocking some network traffic.
