Why Take This Course? 7 � Networking is one of the most critical topics in CS � There would be no… ■ Web ■ Streaming media ■ Big Data ■ Cloud ■ Apps or mobile computing � … without networks

Goals 8 � 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 � Not software engineering � Project-centric, hands on experience � Real projects, protocols, etc.

Online Resources 9 � Course webpage with schedule and lecture notes � https://course.ccs.neu.edu/cs3700sp20/ � Class forum is on Piazza � Link is on the course webpage � Sign up today! � Install their iPhone/Android app � When in doubt, post to Piazza � Piazza is preferable to email � Use #hashtags (#homework1, #lecture2, #project3, etc.)

Teaching Style 10 � I am a researcher � 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 11 � Two textbooks, both optional � Computer Networks: A Systems Approach (Peterson and Davie, 5 th Edition) � Distributed Systems: Concepts and Design (Coulouris etal., 5 th Edition)

Workload 12 Projects (5) 4%, 12%, 12%, 8%, and 14% (respectively) Homeworks (10) 2% each Exams (2) 10% Final 14% Total 100%

Projects 13 � This course is project-centric � 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 14 � Languages � You may choose the language for the projects (see course website for fine details) ■ Code must compile on the CCIS Linux machines � Project 1will be out this week, due Thursday January 16th � Project questions? � Post them on Piazza! � What's that again: Post them on Piazza!!

Project Groups 15 � Most projects will be completed in groups of two � Unless we have odd numbers… � Yes, you can work by yourself, i.e. a group of one � Partner selection � Pick whoever you want � You may switch partners between projects ■ Yes , you can a different partner for EVERY project � 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 16 � Each student is given 4 slip days that they can use at any time to extend a project 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 � After slip days are used, it’s 20% off per day late

Participation 17 � 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

Exams 18 � Exams and Final � 90 minutes, out-of-class � The exams are scheduled for 6-7:30 PM, on February 10 th and March 23 rd � 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 19 � 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 � Detailed instructions for challenges in on the class website

Grade Changes (Continued) 20 � 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 21 � Do not do it � 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 anyone or from anywhere is forbidden

Final Grades 22 � At the end of the semester, all of your grades will sum to 100 points Exams Final Homeworks Projects 20 + 4 + 12 + 12 + 8 + 14 + 10 + 10 + 10= 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
