Course Outline

The networking world is evolving constantly. Previously separated networks such as telephone networks, cellular networks and the Internet are converging and soon all services will be provided based on IP-networks. Next Generation Networks (NGN) describe such architectures where services are provided across different networks based on the Internet paradigm. In addition to traditional, operator controled services, so called Peer-to-Peer (P2P) services are emerging in such environments. P2P systems are based on the user's devices rather than on heavy network infrastructure and thus mark a paradigm shift in communications networking. This course will introduce into the most important communication network and service architectures in IP-based mobile and fixed line communication networks. One part of the lecture addresses the evolution of traditional telecommunication systems towards the Internet starting from Internet telephony to the IP Multimedia Subsystem, which is used in UMTS for push-to-talk and presence services today. The second part is deadling with Peer-to-Peer technologies and services. The general focus is on upper layer (above TCP/IP) communication protocols. The course teaches the basic protocols and algorithms for signaling and P2P overlay networking as well as practical aspects of system evaluation and Internet standardization.
