• What will this course cover?
• Issues related to QoS over data networks
–
–
–
–
QoS architectures: IntServ, DiffServ, MPLS
Signaling protocol: RSVP
Issues in router support for QoS (packet scheduling)
Issues in end-to-end QoS support (reservation .vs.
provisioning)
– QoS/constraint/policy based routing
– Traffic Engineering
• QoS application: Voice over IP
• DWDM networks and QoS over DWDM networks
• Objective:
• Understand the research issues in this area.
• What are you expected to do in this class?
– Read the related materials before coming to the
class.
– Go deep on your own – the lecture will only
cover the key concepts.
– Term project – start now!!!
• Literature search
– SCI, EI, WWW, books, papers.
• Reading
• Writing
• Potential project topics:
– You can choose your own topic, anything
related to networking will do.

– Next Class: review general networking
concepts
– What should you do before the class?
• Decide a term project topic.
• Preliminary literature search for your topic:
– 2002, 2001 SIGCOMM, INFOCOM, ICC, GLOBCOM
– Can’t find a paper in the above list  you have a bad
topic!!!
