The current laboratorial lecture taught how to deploy a Ryu SDN application that offers an on-demand elastic service, which is designated as the fog datacenter. The fog datacenter automatically detects the need to activate a part of the network topology before routing some traffic destined to some destination node. This destination node is also activated before the SDN application controlling the necessary switches to deploy the routing path through the network infrastructure to that receiving node. This fog datacenter could offer heterogeneous resources, such as networking, computation, and storage, where and when those resources are necessary, at the network edge.

The current laboratory taught how to use the Northbound Representational State Transfer (REST) Application Programming Interface (API) between a top-level application and the Ryu Controller. The top-level application is deployed as curl shell commands, which send HTTP (Hypertext Transfer Protocol) messages to the Software Defined Networking (SDN) controller REST API for managing the network topology. The network topology is emulated by Mininet. The REST API of Ryu was extended to support new functionality involving the management of Virtual LANs (VLANs) over the network topology.
