  1. CSci5221: Advanced Computer NetworksProf. Zhi-Li Zhang Welcome to Time: 6:30pm –9:00pm Wednesdays Location: Mech 108 Spring 2013 3 credits Logistics

  2. What is Csci5221 about? • Second “Graduate-Level” Networking Course • Assume a first-course “Introduction to Networking” • csci5211, csci421 or equivalent • We’ll learn about • Fundamental networking principles and techniques • Advanced networking mechanisms, protocols and practices • foundational material: long half life • deeper understanding of R& D issues in today’s Internet • mix of theory and practice • case studies • Who is it for? • primarily for graduate students who want to learn more about networking and systems • undergraduate students encouraged, but special permission Logistics

  3. Course Mechanisms • Lectures, Readings & Homework Assignments • A series of (advanced) topics combining both theory and Practices • Fast-paced • Me: lecture and provide some highlights to guide you understand the reading materials • You: read papers and learn by yourself • “Hands-on” Course Projects • Project 1: Window smart phone programming (or Android) + Azure cloud service support • Project 2: a “research-oriented” networking project (e.g., multi-path routing using VIRO) Logistics

  4. Course Topics • Review of Networking Basics (csci5211/csci4211) • Network Architectural, Design, Implementation Principles • Overlay and P2P Networks; CDNs; YouTube & Netflix Case Studies • Router Design, IP Address Look-up & Flow Classification • Packet Scheduling, Congestion Control and Active Queue Management • Internet Measurement Basics: Traffic, Performances, etc. • Intra-Domain Routing and Traffic Engineering • Network Failures and IP Fast Rerouting • Inter-Domain Routing and BGP; BGP Policy Issues; • BGP Routing Instability; Impact of BGP Failures • Data Centers and Cloud Computing Overview • Data Center Networking and Large Enterprise Networking • Internet Architectures Revisited • …… Logistics

  5. Course Materials • No Required Textbooks • Some Recommended Textbooks (csci4211/csci5211) that will be referenced • Computer Networks: A Systems Approach by Peterson and Davies, 3nd Ed, Morgan Kaufmann • Computer Networking: A Top-Down Approach by Kurose & Ross, 3rdEdition, Addison Wesley • Other Useful Textbooks: • Computer Networks by A. Tanenbaum, Prentice Hall, 4th ed • An Engineering Approach to Computer Networks by S. Keshav • Assigned readings: 3-4 required papers • Posted on class website (tentatively, updated as we go along) • Optional papers for background, supplementary and further readings • Lecture notes Logistics

  6. Course Requirements • Will be Fast-Paced ! • Do assigned readings • Be prepared, read and review textbook/lecture notes on your own in advance! • Self-reading materials in textbook: read by your own and will not be lectured • So we can spend more class time on discussion and problem solving! • 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! Logistics

  7. Course Prerequisite • First-Course on Computer Networks • Algorithms, Computer Architecture, OS • Not necessary, but helpful • Basic knowledge of probability • Programming Experiences and Proficiency • e.g., in C/C++ (or Java), Python, C#, etc. • Required! More importantly • Willing to learn and work hard • Love to ask questions and solve problems Logistics

  8. Class Information • Class Website : • http://www.cselabs.umn.edu/classes/Spring-2013/csci5221/ • Announcement Page • Check the class web page periodically • Google Class Mailing List for announcements, Q&As, discussions, etc. umn-csci5221-s13@googlegroup.com • Class Project “wikipage” Logistics

  9. Office Hours and TAs • Professor Zhang’s Office Hours: By appointment • TA 1: Pengkui Luo, pluo@cs.umn.edu • TA 2: Yanhua Li (up to 03/31/13), yanhua@cs.umn.edu Office: Walter Library/DTC B-34/B32 Office Phone: 612-624-6208 Office Hours: Tu/Th 11am-12pm & by appointments Logistics

  10. Workload and Grading • Workload • Two homework assignments (20% -- 10% each) • Two course projects (50% total, I: 30%; II: 20%) • One take-home exam (25%); • Class participation: 5% (for on-campus student only) • Optional Bonus Points: volunteer to be scribes! • Focus more on critical thinking, problem solving, “heads-on/hands-on” experiences! • Read and critique research papers • Understand, formulate and solve problems • Two Course Projects Logistics

  11. Policies and Guidelines • No late hw/project • Please start working on your hw assignments/projects early and hand them in on time! • Make-up exams: only if special occasions • 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! • Take-home exam: must work it independently! • Acknowledge reference/credit if receive help! • University’s code of conduct enforced! Logistics

  12. A Few Words on Course Projects • Projects will be in groups! • 4-5 students per group, depending on enrollment • Project I: Window Mobile Phone Programming Project • You’ll be learning C#; • Each group: one of several suggested project ideas/topics; • You may create your own project ideas, subject to approval by us • 10 (?) Window mobile smart phones will be provided for you; and free Azure account per project • If you prefer to program for Android smart phones (or Apple iPhones) that should be fine also -- provided you have access to such phones • CSE Dept. may have several Android phones for loan • Project II: “research-oriented” networking project • multi-path routing, fast rerouting, etc. based on VIRO • VIRO: a new routing platform we have developed for future large-scale enterprise networks • Programming in C++ (can be Java, or Python) Logistics

  13. Class Registration Put the following information on a piece of paper • Your Name and Student Id • Your Contact Info: e.g., email, or phone • Your Major and Status: e.g., CS grad, registered, … • Background: • Relevant courses taken: e.g., basic networking, OS, architecture, probability theory, .. • General programming skills: e.g., proficiency in C, C++, C#, Java, Python, … • Network and Web Programming: e.g., experiences in BSD socket, winsock, javascript, php, ajax, … • Motivations and Objectives, : • Why do you want to take this course? • How much time do you think you’ll devote to the course (reading, homework, project …) • Objective: e.g., you’ll work hard to get an A++!
