Communications Networks and Services (Bachelor in Sound and Image Engineering, 2nd course, 2nd semester). Redes Multimedia (Bachelor in Sound and Image Engineering, 3rd course, 1st semester).

With respect to knowledge, at the end of the course the student will be able to: - Know the different signaling architectures of voice services, in both circuit-switched networks (SS7 Signaling System) and packet networks (H.323 and SIP). - Know the different architectures of IP video telephony (SIP and H.323), Video on demand (VoD) and existing IPTV. - Know scalable implementation alternatives. - Know the limitations and alternatives for transporting real-time multimedia streams over packet networks. - Know the multicast service and the main multicast routing algorithms. - Know the quality of service facilities in various network technologies. - Know multimedia transport protocols over packet networks, such as RTP. In terms of competences, they can be classified into two groups: specific competences and generic competences or skills. With regards to specific competences, after the course students will be able to: - Analyze and compare different design alternatives of multimedia services. - Configure various QoS parameters in a network to support a telephony system. - Identify and solve multicast distribution issues. - Create services with group support. - Use of transport protocols for applications or networks with special characteristics. With respect to general competences or skills, the course will focus on: - Broad view on the various protocols in multimedia networks judiciously applying the knowledge gained. - Ability to function on disciplinary teams to solve the raised work, distributing the workload to deal with complex problems. - Recognition of the need for continuous learning and ability to access and understand technical literature. - Contact with technologies widely used in the networks of telecommunications operators and of distribution of multimedia content. - Ability to design systems and content distribution networks, as well as to design multi-network multimedia applications. In terms of attitudes, after completing the course students should have: - Proactive with respect to collaborating with colleagues, to complete complex tasks as a group. - Proactive about the need to understand the technologies considered prior to their configuration.

This course covers multimedia networking protocols, where basic techniques are studied to design, configure and operate networks and multimedia services. The program is divided into four parts: PART I: Audiovisual services and distributed multimedia applications, Network requirements and protocol architectures. PART II. Multicast routing service. Case study: IP television in telecommunication operator networks. PART III. Multimedia transport protocols over packet networks PART IV. QoS architectures in packet networks. PART V. Services based on multimedia streaming. Case studies: video-on-demand services in the Internet (Netflix and YouTube). PART VI. Signaling of multimedia services over packet networks. IP telephony services.

The teaching methodology will include: 1) Theoretical lectures, which will include the main knowledge that students must acquire. Discussions and resolution of doubts about the concepts acquired by the student in the self-learning process. Review activities. To facilitate its development students will have basic reference texts, enabling them to delve into the various topics covered by the course. 2) Laboratory classes, where students will cooperate in working groups of two or more persons to engage in practices designed to apply, consolidate and deepen into the various theoretical knowledge thought during lecture sessions. 3) Resolution of exercises by the student that will serve to assess their knowledge and acquire the necessary competences. 4) Classes of practical exercises, to address a joint correction of the proposed exercises, which should serve to consolidate knowledge and develop the ability to analyze and communicate the relevant information to solve problems.
