The seminar on communication networks serves two different purposes:
  • The topics offer an overview on some aspects of Quality of Service (QoS) in IP networks
  • The students get some practice in preparing and giving technical / scientific presentations.

Ultimately, students are expected to acquire some deep knowledge about a prescribed technical topic and to communicate this topic in a clear, concise, and overseeable manner to fellow students. To this end each student:

  • independently collects and evaluates material (from books, journals, WWW), starting from some initial material handed out by the respective supervisor,
  • has to give a 30 minutes talk and to moderate a following discussion lasting 10 minutes, and
  • prepares a detailed document (``script') containing the presented information including aspects from the discussion.

The seminar will be held as a block seminar at December 17/18, 2002, each day starting at 10am. The script has to be delivered until January 20, 2003.


  • DiffServ
    IP DiffServ (Differentiated Services) is a basically stateless approach to enhance todays IP networks with multiple service classes
  • IntServ
    : IP IntServ (Integrated Services) achieves QoS with a stateful scheme (by reserving resources in routers)
  • MPLS
    : MPLS (Multiprotocol label swapping) is a method for fast forwarding of IP flows
  • IP Multicast
    : Different approaches to support group communications in IP networks
  • Mobile IP
    : Mobile IP allows hosts to roam into foreign networks while maintaining connectivity
  • Voice over IP
    : Specific requirements and architectures for transmitting voice data over IP networks
  • Interplanetary Internet
    : TCP/IP communications over *really* long distances
  • Active and Programmable Networks
    : two different approaches for adding new functionality to an existing network
  • ISO Systems Management Framework
    : concepts and architecture for systems management as seen by ISO
  • Internet Systems Management Framework
    : systems management as seen by the IETF
