IP-based networks have evolved from their original use for pure best-effort data communication services to a universal network platform for multimedia communication services with high quality of service requirements and, as so-called Next Generation Networks (NGN), form the central platform for multimedia services. The module "Multimedia Networks" deepens the knowledge of IP-based networks and expands it with concepts for multimedia networks and for the network architectures of Next Generation Networks. This primarily includes aspects of quality of service support in IP-based networks, signaling for multimedia applications, encoders and decoders for multimedia data streams and protocols for their transmission in IP-based networks. Current developments in the field of these technologies are also examined.  

1. introduction to the concepts of multimedia networks and next generation networks (historical development, requirements, basic characteristics)
2. deepening of aspects of IP-based networks (e.g. Internet architecture, limits of scalability, Internet of Things)
3. quality of service support (QoS) in IP-based networks: (basic concepts, components for traffic control, queues and scheduling mechanisms, quality of service architectures IntServ and DiffServ)
4. multiprotocol label switching (MPLS) and traffic engineering
5. protocols and network architectures for Next Generation Networks (architecture examples, Session Initiation Protocol (SIP), SIP network architecture, SIP and QoS)
6. encoders and decoders for multimedia data streams
7. protocols for the transmission of time-critical data in IP-based networks
8. current developments in the field of network technologies (e.g. virtualization, software defined networking) 

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

Fundamentals of communication networks and communication protocols;
Detailed knowledge of TCP/IP protocols

Students expand their knowledge of IP-based networks with knowledge of network architectures of multimedia networks and their concepts for quality of service support and protocols for data transmission and signaling. They will be able to explain the functionality of codecs for multimedia data streams and learn about current developments in the field of these technologies.  

Students will be able to explain different concepts for multimedia networks. They understand the importance of quality of service for the provision of multimedia communication services and can explain basic concepts for the realization of quality of service. They understand the tasks and concepts of signaling for multimedia applications in communication networks. They will be familiar with various architectures for the provision of multimedia services based on IP-based networks and current developments in the field of network technologies. In particular, students have a comprehensive and detailed knowledge of the possibilities of realizing Quality of Service, especially in IP-based communication networks. They have detailed knowledge of current protocols for the transport of time-critical data in IP-based networks and of signaling with the help of the IETF's SIP (Session Intiation Protocol). They understand the protocol, the SIP architecture and typical communication processes in detail. You will be able to explain the concept of Next Generation Networks in detail.

Students will be able to compare and evaluate network concepts and solution strategies for supporting multimedia services in different scenarios. They are able to assess the achievable quality of service and the signaling effort and question different approaches to providing multimedia services in IP-based networks. They will be able to evaluate the possibilities and limitations of using different technologies and assess new developments.

Students will be able to analyze communication requirements in multimedia networks with regard to performance, quality of service and signaling effort and derive solution approaches and suitable network concepts for different communication scenarios. They will be able to appropriately dimension mechanisms for quality of service support and plan and implement suitable signaling components for multimedia applications.

Students master the specific technical vocabulary of the areas under consideration and are able to precisely describe the quality of service and signaling requirements of a multimedia communication scenario, question technology-specific boundary conditions and derive and present solution strategies for a specific problem.
