Today's modern networks have to meet an extremely wide range of requirements: The Internet is no longer just an efficient data communication network, but a platform for multimedia services with different quality of service requirements and for a wide range of commercial applications. Industrial networks place particular demands on robustness, availability and real-time capability. The Internet of Things (IoT) requires an unprecedented number of connection options for physical and virtual objects that communicate with each other and in turn generates completely different traffic characteristics than conventional services. Various application areas such as healthcare, road traffic or intelligent networking in energy generation systems (smart grids) further increase the heterogeneity of the requirements that modern networks must meet and fulfill as efficiently as possible. 

In the "Advanced Network Technologies" module, current requirements for IP-based networks are considered and more advanced concepts are derived from this, with which these can be provided in the environment of wired technologies for local networks and IP-based networks. This includes aspects such as quality of service support in IP-based networks and in layer 2 networks, redundancy concepts, the implementation of real-time capability in industrial Ethernet systems or in time-sensitive networks, signalling for multimedia applications in IP-based networks or concepts for network virtualization. 

1. communication needs and requirements for IP-based networks in current communication scenarios (e.g. in IP-based multimedia networks, in industrial networks in production environments, in the Internet of Things)
2. quality of service (QoS) support in IP-based networks
3. concept of connection-oriented packet transmission using the example of MPLS
4. redundancy concepts to increase availability in local networks (e.g. spanning tree protocols, layer 2 multipathing concepts)
5. special requirements for Ethernet technologies due to time-critical data (e.g. real-time capability in Industrial Ethernet technologies, Time Sensitive Networking (TSN))
6. architectures and protocols for Next Generation Networks, in particular protocols for signaling (SIP) and for the transport of time-critical data (RTP);
7. basic concepts of network virtualization (e.g. Network Function Virtualization, Software Defined Networking)
8. introduction to IoT technologies (Internet of Things)

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

Lecture on communication networks and basic knowledge of TCP/IP-based networks and protocols

Students expand their knowledge of IP-based networks beyond basic functionality to include current concepts for quality of service support, redundancy and signaling options for multimedia networks. They understand the different requirements for communication in multimedia and industrial scenarios and are familiar with protocols and advanced network technologies for their implementation.

Students deepen their knowledge of IP-based networks with regard to redundancy, quality of service support, real-time capability and signaling options: They have a detailed knowledge of quality of service support in multimedia networks and of the possibilities and limitations of using advanced Ethernet and IP-based network technologies in multimedia application scenarios and industrial environments. They can also discuss different approaches of Industrial Ethernet technologies and Time Sensitive Networks (TSN) for the realization of real-time requirements and evaluate them for the respective application. They understand different approaches to the redundant design of Ethernet-based LANs, can describe the architecture of Next Generation Networks and explain their signaling processes with the help of SIP. They will be familiar with the basic concepts of network virtualization.

Students will be able to analyze the requirements for communication in different environments with regard to performance, redundancy, quality of service and signaling options and question possible solutions and suitable network concepts for different communication scenarios. They will be able to assess the possibilities and risks of using different technologies and evaluate new developments in terms of their suitability for different applications.

Students will be able to design application-specific network concepts and solution strategies for the use of Ethernet and IP-based networks in different scenarios. They are able to appropriately dimension quality of service mechanisms in IP-based networks. They will be able to evaluate the suitability of different concepts, network technologies and network architectures for different applications and identify and select suitable concepts and technologies for these application scenarios on this basis.

Students master the specific technical vocabulary of the areas under consideration and are able to precisely describe the specific requirements of an application scenario with regard to performance, quality of service and redundancy requirements, discuss technology-specific framework conditions and present solution strategies for a specific problem.
