The increasing need for automation and digital transformation introduces multiple challenges to telecom service providers, such as technological, organizational processes, and personnel skills. New technologies are being adopted like virtualization, cloudification, and application and microservices containerization.
The fifth generation of mobile networks represents a tremendous paradigm shift for telecom operators due to the number of technological transformations, as well as a whole new set of services for the industry, such as network slicing, imposed by the 3GPP standard.
With the cloudification of network platforms and services of operators, as well as the adoption of SaaS models in telecommunications operational and business support systems, connectivity between the user and the cloud becomes a focal point in this digital transformation. Therefore, in our lecture, we will address the technological advancements that underpin connectivity, such as optical switching, IP, and Software Defined Networking control.
These are the topics to be addressed at the next lecture by Altice Portugal / MEO.

Join us for a captive presentation exploring the intricacies of Local Area Networks (LAN) within enterprise landscapes. Explore into the challenges of present-day LAN architectures, from managing complex environments to address security vulnerabilities, while discover the revolutionary advantages of Software-Defined LAN (SD-LAN), offering agility and scalability to adapt to evolving network demands.
Our session culminates in a case study showcasing the LAN transformation journey in a multinational company. Gain practical insights into network security enhancements and operational efficiency improvements on a global scale. This seminar promises to unravel the complexities of current LAN challenges while showcasing a path forward with SD-LAN solutions.
Don't miss the opportunity to engage actively and ask questions about the SDN solutions shaping the future of enterprise networks.

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.
