Why Take This Course? How many of you have checked your email, FB, texts… Today? In the past hour? Since I started talking? Your hand is still down because you’re online at this very moment

Goals Fundamental understanding about computer networks All the way from bits on a wire… … across the Internet… … to a complex, distributed application Focus on software and protocols Not hardware Minimal theory Project-centric, hands on experience Real projects, protocols, etc.

Teaching Style I am a network researcher Solution: ask questions! Things make sense to me that may not make sense to you I talk fast if nobody stops me Solution: ask questions! Seriously, ask questions Standing up here in silence is very awkward I will stand here until you answer my questions Help me learn your names Say your name before each question

Textbook Two textbooks, both optional Computer Networks: A Systems Approach (Peterson and Davie, 5th Edition) Distributed Systems: Concepts and Design (Coulouris etal., 5th Edition)

Workload Projects (5) 4%, 14%, 10%, 8%, and 14% (respectively) Homeworks (10) 1.5% each Midterm 15% Final Participation 5%

Projects This course is project-centric 5 projects Designed to give you real networking experience Start early! Seriously, start early! 5 projects Due at 11:59:59pm on specified date Use turn-in scripts to submit your code, documentation, etc. Working code is paramount

Project Logistics Languages You may choose the language for the projects Code must compile on the CCIS Linux machines Project 1 will be out on Friday, due September 16th Project questions? Post them on Piazza!

Project Groups Projects will be completed in groups of two Unless we have odd numbers… Partner selection Pick whoever you want You may switch partners between projects Do not complain to me about your lazy partner Hey, you picked them Can’t find a partner? Post a message on Piazza!

Late Policy Each student is given 4 slip days that they can use at any time to extend a deadline You don’t need to ask me, just turn-in stuff late All group members must have unused slip days i.e. if one member has zero slip days left, the whole group is late Assignments are due at 11:59:59, no exceptions 1 second late = 1 hour late = 1 day late 20% off per day late

Participation This is a high-level college course I’m not taking attendance I don’t care if you skip lecture That said, please come and participate! Ask questions! Ideally, I want to know everyone’s name by the end of the semester Participation is 5% of your grade If you ask questions in class and post on Piazza then you’ll earn all 5% If you routinely don’t show up to class, or otherwise annoy me, you’ll get nothing

Exams Midterm and Final All exams are: 2 hours, in class The final will be cumulative All exams are: Closed book, leave the laptop at home If I see a smartphone, I will take it and sell it on ebay You are allowed to bring an 8.5x11, double-sided cheat sheet

Grade Changes Each student is given 2 challenges to use as they see fit Challenges can be spent asking for regrades If you think there has been a grading error, come to my office hours If the grade is incorrect, you keep your challenge If the grade is correct, you lose your challenge When your challenges are exhausted, you cannot ask for regrades

Grade Changes (Continued) Challenges may be used for: Projects, homeworks, and tests Challenges may not be used for: Late assignments, use of slip days If you want to challenge a project grade, all group members must have an available challenge Your challenge succeeds or fails as a group

Cheating Do not do it Cheating is an automatic zero Seriously, don’t make me say it again Cheating is an automatic zero Must be referred to the university for discipline and possible expulsion Project code must be original You and your groupmates only Unless we give you starter code, obviously If you have questions about an online resource, ask us Homeworks must be done individually Copying answers from friends or former students is forbidden

Final Grades At the end of the semester, all of your grades will sum to 100 points 15 + 4 + 14 + 10 + 8 + 14 + 15 + 15 + 5 = 100 Final grades are based on a simple scale: A >92, A- 90-92, B+ 87-89, B 83-86, B- 80-82, … I don’t curve grades Homeworks Projects Exams Participation
