Requirements for spring-2010:

• Prepare and make a seminar presentation. This can be made individually or 2 persons groups. Topics for the seminar:
  • Explain and compare different scheduling diciplines. Some examples presented here
  • Explain and compare different congestion control mechanisms (eg. RED, WRED and DWRED).
  • Explain and compare leaky and token bucket tarffic shaping methods. Check eg. this
  • Explain and compare packet by packet EWMA meter, Windowed EWMA meter and Time Sliding Window Meter. Check eg. this
  • QoS Requirements of VoIP and Video streaming. Check eg. this document
  • Propose your own topic related to the networking QoS
  
  
• Complete 6 home exercises (4 for seminar speakers). Ask exercises from the lecturer.
  
  
  • Pass two laboratory exercises related to the networking QoS. Ask laboratory works and time from the lecturer.
