TIETOKONEVERKKOJEN JATKOKURSSI (3 op)
Advanced Computer Networks (3 cu)
This course is lectured in Finnish. Contact timo.t.hamalainen@jyu.fi to complete the course in English.
Content
Functional aspect to the Quality of Service (QoS) in networks; components,
protocols and management. The main focus will be Quality of Service in IP
and wireless networks. QoS mechanisms like:
- Traffic classification and marking
- Traffic regulation
- Resource sharing
- Congestion management
will be explored and analyzed.
Book:
- J. Joutsensalo, T. Hämäläinen, and A. Sayenko: QoS Supported Networks,
Scheduling, and Pricing; Theory and Applications
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.
