AG Technische Informatik

Proseminar Technische Informatik

The Proseminar Technische Informatik expands on other Bachelor-level lectures with focus on technical computer science. Students pick a topic related to current technology and/or partially covered in the previous lectures and write a report (12 A4 pages including figures and references, single column, 1.5 spacing, 11-point font) discussing corresponding questions. At the end of the term, the participants present their results in the form a short talk (20 minutes + 10 minutes Q&A) in a meeting. This course places special emphasis on dealing competently with academic and primary literature, structure and legibility of the report, and the style of the presentation (50% of final grade). During the term, there will be deadlines for status reports, but no weekly meetings of the complete seminar group.

VLAN-Induced sharing in Campus Network
Virtual LANs (VLANs) allows to create logical broadcast domains on switches. They provide flexibilty to separate networks. However, they introduce complexity with respect to the IP network on top. Based on a recently published measurement study at ACM IMC 2009, you should provide insights into "Characterizing VLAN-Induced Sharing in a Campus Network". How could you infer a layer-2 topology? How does the layer-2 topology depend on the IP network? What are the implications for network management tasks (e.g., planning for capacity or reliability)?

Towards a better understanding of BGP with C-BGP
The Border Gateway Protocol (BGP) is the de facto standard for dynamic Internet backbone routing. BGP routes used for data forwarding are selected based on a complex decision process that is defined by the protocol. Analysing, understanding, and enhancing the routing between Internet domains (e.g., different ISPs), thus, require not only a substantiated knowledge about BGP, but also tools to emulate BGP internals. C-BGP is aimed at computing the outcome of the BGP decision process in networks composed of several routers. It can be used as a research tool to experiment with modified decision processes and additional BGP route attributes. The goal of this work is to get familiar with BGP and to give an introduction about C-BGP. What are the great ideas and the limits of this software. You are highly encouraged to conduct practical tests.

Visualizing the Internet
The Internet can be modelled as a graph. Nodes may be represented by IP prefixes, Autonomous System numbers, or routers. Visualizing a network with the size of the Internet is an intricate task with respect to processing time and memory constraints, as well as a clear arrangement of the provided information. This work should analyze existing visualization projects and discuss their techniques to create a graphical representation of the Internet. Are there any other approaches in addition to a pure graph layout? Which data can be extracted from Internet measurements and used for visualization? Some of the existing tools are freely available, and you are encouraged to test some of them.
