Why Take This Course? How many of you have checked your e-mail, FB, text… Today? In the past hour? Since I started talking?

Computer networks are ubiquitous Networks touch every part of our daily life Web search Social networking Watching movies Ordering merchandise Wasting time

Computer networks are ubiquitous Networking is one of the most critical topics in CS There would be no… Big Data Cloud Apps or Mobile Computing Streaming video WoW Social Networks VoIP … … without networks

Goals Fundamental understanding about computer networks All the way from bits on a wire… … across the ever-evolving Internet… … to a distributed applications Focus on software and protocols Not hardware Minimal theory Project-centric, hands on experience Programming APIs Network Simulation Application-level protocols Distributed systems

Online Resources http://david.choffnes.com/classes/cs3700sp18 Class forum is on Piazza Sign up today! Install their iPhone/Android app When in doubt, post to Piazza Piazza is preferable to email If you e-mail me a question, I will tell you to post it on Piazza Use folders (homework1, lecture2, project3, 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 (interrupting me is OK!) 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 … but there are 70+ of you, so...

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 Friday of specified week Use turn-in scripts to submit your code, documentation, etc. Working code is critical

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 Thursday, due January 19th Project questions? Post them on Piazza!

Project Groups Projects will be completed in groups of two Except for project 1 And unless we have odd numbers… Partner selection I will pick partners for you In part based on performance in the class so far Same group for 2&3, one-time swap for 4&5 Extra incentive to do well on homework, initial projects

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 Slip days available = average of group members’ slip days i.e. if one member has zero slip days left and the other has two, the whole group has one slip day available Assignments are due at 11:59:59, no exceptions 1 second late = 1 hour late = 1 day late 20% off per day late

In Class 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, post on Piazza, turn in homework, then you’ll earn all 5% If you routinely don’t show up to class, or are disruptive, you’ll get nothing

Exams Midterm and Final All exams are: 2 hours, midterm in class The final will be cumulative, date TBD by registrar All exams are: Closed book, leave the laptop at home If I see a smartphone, I will take it and use it for research You are allowed to bring an 8.5x11, double-sided cheat sheet Guessing is strongly discouraged You get 20% of points for leaving a question blank 0% if you have both a right answer and a wrong answer

Grade Changes Each student gets two challenges Modeled after NFL system If you ask for a regrade and you are wrong, you lose a challenge When you are out of challenges, you cannot ask for regrading Must come to office hours with the following in writing: Specify the problem(s) you want regraded For each problem, explain why the grade is in error Don’t sweat the small stuff Regrading minor things does not make me a happy Professor If the change is <5% of the grade, don’t bother More details on the website

Cheating Do not do it Cheating is an automatic zero Seriously, don’t make me say it again Cheating is an automatic zero I will send any and all suspects to OSCCR without exception CCIS is also tracking cheating, with stricter enforcement Project code must be original You and your groupmates only Unless we give you starter code, obviously StackOverflow/Quora are not your friends Copying from public Githubs will get you an F grade If you have questions about an online resource, ask us

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
