The subject "Broadband Networks" seeks to provide students with an understanding of the nature of multimedia information and the requirements it imposes on the networks that must support its transmission. It intends to show students the general principles of the architecture of broadband networks (local area, access in residential and business environments and WAN) that are used to transmit information with strict requirements (e.g. in terms of bandwidth and latency) such as multimedia traffic. Students are also expected to know the main protocols for sending voice and video, the mechanisms to ensure quality of service (QoS) even when there are interruptions in communication and, in addition, to know examples of current implementations.
