This course focuses on Security and Quality of Service (QoS) in Internet network from technology, regulation and business aspects. It covers Internet fundamentals, including Internet protocols and architectures, Internet security standards and approaches as defined by IETF (Internet Engineering Task Force), as well as ITU's security architectures for end-to-end communications. Further, the course incorporates cybersecurity approaches from the ITU viewpoint, and security aspects of emerging cloud computing and Internet of Things (IoT).

This course focuses on technical, business and regulatory aspects of QoS for Fixed and Mobile Networks. It includes QoS (Quality of Service) and QoE (Quality of Experience) fundamentals by ITU, as well as traffic and QoS management in Internet and IP networks. Further, it includes QoS for fixed ultra-broadband access, including QoS solutions in metallic and optical networks, carrier grade Ethernet QoS, as well as end-to-end QoS. The course also covers QoS for mobile ultra-broadband access, including 4G and 5G mobile technologies and their QoS capabilities and approaches.

In the telecommunications industry, price is no longer the sole factor in purchasing decisions. Service quality plays a key role to all stakeholders and, particularly, in achieving consumer satisfaction. The measurement of Quality of Service (QoS) and Quality of Experience (QoE) is, however, becoming increasingly complex to obtain as quality can be compromised by various factors along the value chain such as with the network infrastructure, the devices and/or applications a consumer is using and other factors influencing a consumer's experience.
