Network Protocols and Architectures (Lecture, WS 2012/13)
The lecture explains the architecture of the Internet and the basics of every communication within it. Beginning with the application layer services like Web (HTTP), Mail (SMTP, POP, IMAP) or name service (DNS) are examined. Afterwards we work through the transport layer (TCP, UDP) and the network layer (IP). Finally, we discuss the interactions of the different protocols. The lower layers (medium access control, data link and physical) are covered by the lecture "TechGI 4" (offered by Prof. Wolisz).
- First lecture: 17 October (de) / 18 October (en) 2012 with an introduction into the research group Intelligent Networks.
- The deadline for the solutions
of the first worksheet is thursday Nov.
1st, 13:55h. Since Web caching was not covered in the lecture yet, we
declare question 4b) for the first week optional. This means that you
can either upload your solution for this question by Nov. 1st or
together with the solutions for worksheet 2 the week after.
Students who can not access ISIS can hand in their solutions in the
postbox in the Telefunkenhochhaus (basement, behind the doorman right).
For any open questions regarding ISIS, the worksheets or the tutorials
you can contact Arne Ludwig.

The lecture explains advances principles of computer entworks based on fundamentals of the topic. The topics are protocol mechanisms, principles of implementation, network algorithms, advanced network architectures, network simulation, network measurement, as well as techniques of protocols specification and verification.
- Protocols: mechanisms and principles of design
Discussion of mechanisms and techniques of protocols used in network protocols. We will discuss why they are used for which purpose.
- separation of control and data channel
- soft state and hard state
- use of randomization
- multiplexing of resources
- localization of services
- network virtualization: overlays
Identification and study of principles, that lead to the implementation of network protocols
- system principles
- reflections on efficiency
- caveats / case studies
- Network architecture: "the big picture"
Identification and study of principles that lead the design of network architectures. We consider substantial questions rather than specific protocol and implementation tricks.
- Internet design principles
- lessons learnt from the Internet
- architecture of telephone network
- circuit switching versus packet switching (revisited)
- Protocols: network algorithms
- self stabilization (examples of routing)
- Kelly's congestion control framework
- closed loop control on the example of TCP
- principles of discrete event simulation
- analysis of simulation results
- packet versus flow models
- bounding strategies (e.g., Chernoff bounds)
- Gaussian distributions

offer this lecture twice:
On wednesdays at 10 a.m the lecture will be held in German, on thursdays at 2 p.m. the same lecture will be held again but this time in English.
are enrolled for a bachelor's or master's course at
TU Berlin, you are required to take the module
"Netzwerkarchitekturen – Grundlagen" ("Network
architectures – Basics"; MINF-KT-NA/Glg.W12) which
includes the tutorials. Therefore, you are required to pass the
Diplom students can either take this course with the tutorials (4 SWS/6 LP) or without (2 SWS/3 LP).
Please see the tutorial's website  for details.
You need 50% of the possible points to pass the tutorials. Again, not passing the tutorials means that you will only get 2 SWS/3 LP for this course. This does not satisfy the requirement of the module "Netzwerkarchitekturen – Grundlagen"
The details for registering for the exam are to be announced and will be given in the lecture and the tutorials as well.
There will be a grading bonus for those who achieve sufficient points for their homework solutions (tutorials):
- A bonus of 0.3 if at least 60% of the possible points are achieved.
- A bonus of 0.7 if at least 75% of the possible points are achieved.
The requirement for granting the bonus is to pass the exam without the bonus! (Those who do not pass will not pass due to the bonus.)
