Suggested topics

This is a list of suggestions for in-depth topics in TDTS02. Feel free to suggest additional topics. The topic descriptions are simply possibilities. You will probably have to focus on subtopics.

Optical networks

Components that make up modern optical networks, such as add-drop multiplexers, optical cross-connects, fibers, and switches. Topologies for optical networks, protocols such as SDH and SONET, and technologies for ensuring high availability. Wavelength multiplexing and wavelength provisioning. Optical packet switching.

The IEEE 802.3 family of protocols

Ethernet switching, the STP and RSTP protocols. Virtual LAN technology. QoS in ethernet networks. Power over Ethernet. Performance of Ethernet.


MPLS protocols. Failover, routing, QoS in MPLS. Relationship with routing protocols. GMPLS.

Ad-hoc networks

Transmission technologies for wireless ad-hoc networks. Routing in ad-hoc networks. Discovery protocols. Security and reliability. Applications of ad-hoc networks.

Access networks

Serial line technologies. ADSL, SDSL, HDSL, and so on. ISDN. Cable modem technologies, such as DOCSIS. Next-generation access networks.

Current topics in computer network infrastructure research

What is going on in the research community that is related to computer network infrastructures. You will need to get familiar with the research publications in the area and present a survey of the current research. This topic is new for 2008 and is expected to require more research than the others.

QoS and traffic engineering

Technologies for QoS and TE. QoS support in routing protocols. QoS support in the network layer. QoS at the data link layer.

Network monitoring

This is an experimental topic. WeÃ've never hd it before, so it is only suitable if you feel that you can work completely independently. In this topic you will study the current state of network monitoring for performance, reliability and security (with a clear emphasis on the former two).

Simulation exercise

In this practical project you will have to define, implement and run one or more interesting, challenging and meaningful simulations to explore some aspect of computer network infrastructure. You will have to do all the work yourselves, including finding the equipment and software required. The technical difficulty of this project is expected to be very high, and you will have to read the theory as well. This is not the easy choice.

Other topics

Other topics are certainly possible, and if they work out well, may be included as standard topics in the future (this is how access networks and ad-hoc networks were introduced). Please discuss any ideas you have with David Byers.
