CSci4211: Logistics5 What is Csci4211 about?  First (Introductory) Networking Course  We’ll learn about  Fundamental principles and concepts in computer networks  How Internet works  Focus on network software architecture and mechanisms  hands-on experiences  via programing projects, wireshark exercises, etc.  Who is it for?  CSci, CE or EE undergraduate students

CSci4211: Logistics6 Course Prerequisite  Algorithms, Computer Architecture, OS  Not necessary, but helpful  Basic knowledge of probability  Programming experience in Python/Java More importantly  Willing to learn and work hard  Love to ask questions and solve problems

CSci4211: Logistics7 Course Materials  Required Textbook:  Computer Networking: A Top-Down Approach by Jim Kurose and Keith Ross, 7 th edition Pearson  Website: Networking-A-Top-Down-Approach-7th-Edition/PGM html  Other Useful Textbooks:  Computer Networks by Andrew Tanenbaum, Prentice Hall,  and many others!  Class Notes and other assigned readings

Lecture Notes Lecture notes will be posted on the class website –Lecture notes provide you an “outline” of the key concepts and materials we will cover in lectures May also contain some supplementary information no in the textbooks –will be posted before class, so please read them before the class if possible! If you want hardcopy, you must print your own. This includes class notes and assignment specifications. –may be updated slightly after lectures Lecture notes are mostly based on the lecture notes by the authors, which you can find on the textbook website –and with many other useful materials!

CSci4211: Logistics9 Class Information  Class Website :   Announcement Page  Check the web page periodically  Class Google Group Mailing List: -- will add you directly using your UMN address  Help Hot Line:

CSci4211: Logistics10 Course Requirements  Do assigned readings  Be prepared, read textbook/lecture notes before class  Attend and participate in class activities  Please ask and answer questions in (and out of) class!  Let’s try to make the class interactive and fun!  Workload  Two homework assignments (“mock” exams): 10% each  Four (small) “hands-on” programming projects: 8-9% each, 35%  Two “take-home” quizzes: 10% each  One final exam: 25%  Grade not based on curve  Everybody can get a A if you work for it!  must pass one of the quizzes and the final exam to obtain a passing grade !!!

CSci4211: Logistics11 “Hands-on” Experiences  It makes no sense to learn about networking without “getting your hands dirty”  Four “small” (individual) programming projects  Emulate some key mechanisms/algorithms learned in lectures  DNS, TCP, routing and LAN switches  Several “hands-on,” interactive lectures (led by TAs)  Capture and go over “real-network” traces using Wireshark  Run emulations or experiments (e.g., using Mininet or GENI)  Quick Q&As a la Jeopardy, and other “fun” exercises  Also help with programming projects  Extra-credit GENI (or mininet) experiments/exercises  GENI (Global Environment for Network Innovation) Testbed  Allow you to set up “toy” networks and run experiments, or deploy your own algorithms and test them  Will set accounts for you if interested -- details will follow

(Reference) Final Letter Grade Criteria [ ] A [ ) A- [ ) B+ [ ) B [ ) B- [ ) C+ [ ) C [ ) C- [ ) D+ [ ) D [ ) F Grades are to help you check how much you have learned, where your weaknesses lie. No competition among members of the class! Everybody have a chance to get A if you work for it Depends on the situations/progress, extra credit would be available

CSci4211: Logistics13 Policies and Guidelines  Penalty on late homework/projects:  Please start working on your hw & programming assignments early and hand them in on time!  Penalty: one day late 10% deduction, thereafter each extra late day 15% deduction. No credit if more than three-days late unless prior arrangements are made.  Make-up exams: only if final conflicts  Incomplete: not granted, unless  proof of emergency, “agreement for incomplete” form  Scholastic behavior:  You are encouraged to study in groups, but do your work independently!  Acknowledge reference/credit if receive help!  University’s code of conduct enforced!
