'''NOTE:''' Please submit multiple files compressed in one ZIP archive by E-Mail to David. For text documents, submit in PDF format.
The subject line of your email should be the corresponding identifier from the table above followed by your name.
''Example:'' Alice wants to submit Exercises 3 and 6. She compresses all the files she created for the exercise into one ZIP archive and sends the archive to David before April 17.
She uses the subject line '''SDN-EX-174 Alice'''
'''NOTE:''' Your final report ([ftp://ftp.springer.de/pub/tex/latex/llncs/latex2e/llncs2e.zip LaTeX Template]) should include:
* Title sheet showing your name and matriculation number
* Exercise 4 (Python SDN Simulator), Exercise 7 (Mininet Controllers), Exercise 8 (FlowVisor)
Python code has to be submitted ready to be executed (i.e., in .py files and NOT IN DOCUMENT).
50% of the points in these exercises are mandatory to pass. Higher scores will improve your grade.
* One review form for each paper you were assigned during the course (Use one [http://user.informatik.uni-goettingen.de/~dkoll/files/sdn/review.docx review form] for each paper).
One review per participant is mandatory to pass. More good (!) reviews can help to improve your grade.
Do not submit reviews for papers outside of your assigned reading group (Exception: Group 8 (single paper group). You can also review the paper "Jin et al, "CoVisor: A Compositional Hypervisor for Software-Defined Networks (USENIX NSDI 2015)").
Make sure that you write your own review. Copy/Paste reviews from other participants of the course will not be accepted. The reviews are individual work.
* The slides you used for presenting your papers in class.
No need to improve the slides after presenting.

==Requirements==
* Basic knowledge in computer networking (e.g., successfull completion of the course "Computer Networks") and object oriented programming is required.
* Students will benefit from knowledge in Python (however, the skills required for the course will be taught).
* Each participant is required to actively attend the course and earn 50% of the points of the exercise.
* Written report at the end of the course.
==Reading List==
If you are interested in reading into some material before the course starts, NEC maintains [http://www.nec-labs.com/~lume/sdn-reading-list.html a somewhat up-to-date reading list].
