The current laboratorial lecture taught how to write a Ryu application that supports scenarios with multiple SDN controllers. There are three possible functional roles for each SDN controller forming the cluster of the diverse SDN controllers. The three possible SDN controller roles are MASTER, SLAVE, or EQUAL. This lecture aims to deliver to its practitioners relevant knowledge in the next aspects: i) study the two possible and exclusive switch reactions for the case the communication with the control plane has failed; ii) show how each SDN controller is configured for its role within the control cluster; iii) evidence how the control cluster formed by distinct SDN controllers gives more strong guarantees against a SDN controller failure at the control plane; iv) study how the cluster SDN controllers divide among them the control responsibility of the diverse nodes of the data plane; and v) study how the SDN controllers forming the control cluster and, using the OpenFlow v1.3 protocol interact with the network devices (i.e. OVS switches) to deploy diverse multi-controller scenarios.

Apresentação feita pela Deloitte conforme o seguinte resumo: "We live times were businesses are evolving and becoming more digital, cloud-oriented and demanding. Given this, organizations need to evolve their WAN infrastructure to cope with new and challenging requirements. By applying SDN to the WAN (SD-WAN), organizations can address many of the challenges of the digital transformation era, providing the necessary tools and intelligence to dynamically scale and centrally manage networks through a single and intuitive interface. This presentation will guide you through the deployment of SD-WAN in a multinational company, with around 400 locations worldwide. It will go from the preparation stages, including WAN assessment and design of the target state, to the actual deployment of the solution and the benefits it brought to the company in terms of network performance and costs."
