Contents

First the data link (like Ethernet and its extensions: VLAN, PPPoE) and network layer the Internet protocols (IP)v4, v6 and ARP are discussed. It comprises mainly routing algorithms. Later on the lecture will present a range of application layer protocols like DNS, Voice-over-IP. Specific problems of SSL, SIP and firewalls (example: Netfilter) are discussed. Additionally the lecture gives a broad overview on standard wired and wireless telephony systems and networks. Within applications the client-server-model of network communication will be introduced. With the knowledge acquired earlier the topics of network security, firewalling, secure protocols, network address translation, quality of service can be discussed in the second part of the lecture.

Exercise

Note that it is mandatory to prepare two exercises to achieve a permit to the final exam!

Also, you have to give us your full name and login name, see this thread.

Your task for preparing the exercise consist of the following:
  • Creating the exercises and preparing all hardware to solve it.
    • You can find the exercise catalogue and the solutions here (pdf).
    • Check the exercises for realization possibility, either with the pool computers or the notebooks provided.
    • Prepare all hardware, e.g. install required tools. You may also prepare a step-by-step solution for installing those tools and have the participants do it in the exercise. This should not take too much time, though.
    • You can take one of the notebooks and prepare it at home. Then you will have to copy the installation to all other notebooks, so that they are identical.
    • We have a VLAN switch you can use for the exercise. You will have to configure it according to your needs, please refer to the user manual. Also, be aware that it is quite a large and not-so-quiet piece of hardware.
  • Create an exercise sheet to distribute to all participants in the exercise.
    • You can use this LaTeX template.
    • Either bring a sufficient number of printouts (25) to the exercise or send it by email until Wednesday, 10am, so we will do the printing.
    • Submit the exercise (pdf and source files) by email.
  • Supervise your fellow students during the practical exercise.
