After successful completion of the module, students understand the principles of resource management for wireless and wireline packet-based communication networks with a focus on layer 2 protocols (medium access control) and their building blocks, and are able to apply methods for protocol design, resource management, traffic engineering and the analysis and evaluation of network protocols and architectures.

Medium Access Control and Resource Management for wireless and wireline networks and their performance analysis: - Medium Access Control (MAC) - performance analysis based on queueing theory - (wireless) contention-based MAC (e.g. in WLAN, Ethernet) - resource partitioning, polling - cellular network resource management: OFDMA, scheduling algorithms, cellular principles, protocols (e.g. LTE, 5G) - packet switching, label switching (MPLS), routing - Software Defined Networking (SDN)

Basic knowledge of communication networks and their analysis: - packet based networking - data communication protocols incl. TCP/IP - evaluation methods for communication network performance analysis

Learning method: In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in exercises and tutorials. Teaching method: During the lectures students are instructed in a teacher-centered style. The exercises are held in a student-centered way where examples of state-of-the-art wireless and wireline communication systems are discussed and calculated. In addition, students are asked to read 1-4 scientific articles to be discussed during the lecture and tutorial hours to link the methods to current challenges for future communication standards.

In a written exam (90 min) students proof their understanding of data networking and the related methods by answering questions. With given use cases students proof their ability to apply methods for protocols and mechanisms, e.g. for wireless and wireline data communication networks, by calculations. During the semester an optional written mid term exam will be offered, which can be used to improve the final grade. The final grade is composed of the following elements: - 100% final exam The mid term exam results can be calculated with a bonus of 0.3 to the result of the final exam, if this leads to an improvement of the overall grade.
