The basic aspects of IP based networks has been explained in the lecture Rechnerkommunikation. This advanced lecture Communication Systems provides insight into other networking techniques. It includes circuit switching in telephone and optical networks, virtual circuit switching (e.g. MPLS), multimedia communications in packet switched networks (streaming, RTP. H.323, SIP, Multicast, IPTV), quality of service in packet switched networks (Integrated Services, RSVP, Differentiated Services, Active Queue Management, Policing, Scheduling), wireless and mobile communication (GSM, UMTS, LTE, Wimax, WLAN, Bluetooth, sensor nets, Mobile IP) and industrial communication in automation networks. The exercises include practical assignments in a lab environment: the lab contains several IP routers, switches and hosts, IP phones and softphones for VoIP communication. All these devices will be configured and tested. An additional lab consists of an SDR-based LTE base station and several mobile phones. It allows to observe and understand the architecture and communication messages on different layers of the protocol stack.

Educational Objectives and Competencies

  • Knowledge of technologies in circuit and packet switching in wireline and wireless / mobile networks
  • Knowledge of network system design
  • Practical experience in configuring an IP switch router network with multimedia traffic as well as programming interconnected embedded systems
