Computer Science in one word
Abstraction
“a mechanism and practice to reduce and factor out details so that one can focus on a few concepts at a time”
- wikipedia

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

Life comes at you fast
when you connect any lab machine to the
Internet.
Always be careful and ask yourselfbefore 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?”
