Am In the Right Room?

This course does not directly address




“How do I make money on the Internet?”
“How do I configure an Apache web server?”
Social/psychological impact of the Internet
This course


involves much more than using internet applications
will require significant effort (projects, HWs, and exams)
5
Course outline, Part I:
Introduction

Brief history of networking and the Internet

Protocol layering

Connections vs. connection-oriented service

Packet switching vs. circuit switching

Edge vs. core
6
Course outline, Part II: Internet
Protocol Layers

Application layer
 Web and HTTP, ftp, mail, DNS, P2P file sharing, and socket
programming

Transport layer
 UDP, TCP, flow and congestion control

Network layer
 Routers, IP, routing algorithms and protocols, broadcast and
multicast

Homeworks

Each student must provide

His own solution

Due at the beginning of the class on due day

Ok to discuss problems with other students

Not ok to share solutions
9
Exams

Goal:

Ensure you grasp fundamentals of networking

May include multiple choice questions

Final exam will be comprehensive – based on



Text,
lectures,
homework assignments and projects

Miss the final exam without a valid excuse => F
Make-up exam

only under truly extraordinary circumstances
11
Specific Teaching Goals

The design of this course and its policies attempts to
 Prepare and reward good students because


Network impact quality of life

Unskilled practitioners are dangerous

Skilled practitioners are valuable
Improve your skills in

Network design and analysis

Performance analysis

Documentation design
12
So what is a good student?

A good student is someone, who

Is motivated (tries hard)

Has aptitude (can do the work)

Has good background (knows the prerequisites/basics)
13
Why you shouldn’t take this
course?

You are not ready for hard work

You don’t have 2 hours/week

You just want to sit and listen

You are not ready to take the initiative

Only key concepts will be covered in class

Students are expected to read the rest from the book
14
NonGoals of the course

This course is not intended to

Focus on the implementation specifics of a vendor

Provide


Cisco/3com/Novell (or any other brand) certification
But, I can promise the following

This course make these things easier to learn

Once you know the general principles and “Big Picture”
15
Summary

Computer networking is important for all areas of computing

Goal: to prepare you for a career in networking

Get ready to work hard
16
End-user perspective

Like many people



Is that of a user of the network

As opposed to the network engineer
As students


Your perspective about networks
You view the Internet as a connection thru a wall plug
What happens behind the wall plug is magic !!
