Labs, Project and Homework Assignments

• Please follow lab web site, SUCourse and email announcements for lecture and lab related homeworks. Homework assignments will not be posted from this web site.
• There will be 4-5 labs (some of them may last several weeks). During these labs you will have hands-on experience and/or practical lectures on C# language, socket programming, Internet protocols (via packet capturing and analysis), DNS and various server installations and configurations, LAN design and implementation, IP subnetting. More information on lab sessions will be posted on the lab web site in time.
• The labs WILL NOT be direct application of the lectures, but they will be related to each other. We DO NOT aim to use labs as recitations to help the students to get higher marks in the exams.
• There will be one or two homework assignments about lecture material. Moreover, there will be either homework, quiz, project or in-lab performance to be graded related to each lab. Moreover there will be a term project and its weight will be greater than or equal to 20%. Homework assignments are to be done individually, but the project will be done in groups. Project requires programming and it is about development of applications that run on networks (this may also require an application layer protocol design). The project will be done in three phases with different deadlines and grading.

Tentative Grading

Midterm exam 30%
Final  35%
Homework, project and labs 35%

Make-up Policy

No make-up! If you miss something, you miss it, no matter the reason is! If the reason is really valid, you may take an oral examination instead of a written make-up.
