Real Network Protocols • “RIP is a distance-vector protocol that operates in a manner very close to the idealized DV protocol we examined” • Computer Networking: A Top-Down Approach 4/e
Course Objectives • The main idea: learning by doing • Build a network using PCs, routers, cables • Configure them properly • Run the experiment • Observe real network protocol behavior • Gather data • Analyze and evaluate • Explore how abstract concepts are designed to work in real life and to observe how they really behave
Course Objectives • Reinforce your knowledge of networks • Gain first-hand experience and skills • Learn how to use Linux for networks • “Is there a way to do better?” or “Why?” • Beginning of network research • Pre-requisite • Computer Networks or equivalent
Lab Organization • Each lab has three parts • Prelab HW - individually • Lab session • Lab report • You need to bring • Your Lab Manual • A USB drive to store your data in groups of two
Lab Times • Mondays 4 ~ 6 pm • Tuesdays 4 ~ 6 pm • Wednesdays 10 ~ 12 pm (if class > 20) • 10 students in each lab time • Please sign up!
Lectures • Wednesdays 1:10 ~ 2:10 pm at 253 ENG • Go over topics in the upcoming lab • Discussions on reading assignments • Will not be an extensive review of relevant Computer Networks material
Grading Open-book, open-notes, open to quiet discussions
Homework Policy • Prelab HW • Individual work • Due every Friday at 11:59 pm • Don’t copy and paste from other sources • Lab reports • Team work • Due before next lab • Don’t turn in 100 page reports! Avg. 5~20
Homework Policy • Late submission • 20 points deducted per day • But you can use 3 late days • At most 1 week for reconsideration after grades are announced
Life comes at you fast when you connect any lab machine to the Internet. Always be careful and ask yourself before you plug it in: “Where is the other end of the cable?”
To get the most out of this course • Prepare for labs in advance • Read the lab manual beforehand • If you’re not familiar with something in the lab, consult textbook, ask me or TAs during office hours • Submit your prelab HW on time • Come to class • For long term benefit, ask “Why?”
Main Points of Lab 1 • Getting acquainted • Hardware setup • Linux • VirtualBox • Network tools (ping, tcpdump, wireshark) • Lab reports • How to capture data • What to include / exclude in lab reports
Homework • Prelab 1 due on Friday (01.23.2009) • Read RFC 826 by next class
Contact and Office Hours • Instructor Jong Yul Kim (jyk@cs) Wednesdays 2:10 ~ 4:00 pm at CEPSR 721 • TAs Sambuddho Chakravarty (sc2516@cs) TBA Wonsang Song (wonsang@cs) TBA
