Course Description
Computer Networks investigates the 'System' of Computer Networking:
its principles, its protocols, its implementation, and its analysis.
The course has a significant laboratory requirement.
The course prerequisite is CS 70, but CS 105 would be helpful.
Course Text
I informed Huntley Bookstore of the primary textbook.
While the K&R$ 7th Edition is the latest, the 6th is satisfactory.
The major issues are:
different problem numbers;
and access to the online materials.
As far as problem numbers, I will try to reconcil that in various ways.
But
you will NEED access to the online materials. It is my understanding
that if you did not purchase the book new, you can pay $25.00 for such access.
K&R is not the only book that is suitable for the course. Again
the issue is not usually content, but rather problems and labs.
There are obviously many places to purchase books,
e.g., Amazon.
Do what is best for you.

What Is This Course About?
There are many ways to approach the subject of computer
networks.
In early years, the course was centered on
the
analysis of the
individual protocols in the TCP/IP protocol stack.
In recent course offerings I have used
Peterson and Davie or Kurose and Ross,
to investigate
computer networking from a systems perspective.
Peterson and Davie
are strongly oriented towards the Internet and TCP/IP, but
their presentation has a global view of the interaction
of various protocols.
The current text presents TCP/IP from the top down,
while focusing on networking protocols and
on analysis of networks traffic.
The lectures and labs will be a combinaion of both approaches, something that I call "outside-in"
because it is neither bottom up nor top down.
We will experience the course at 3 levels:
-
First:
TCP/IP protocols will be investigated outside-in:.
-
Second:
the systems approach
of P&D will be used to provide a more global view of networking.
In particular, we will investigate how IPv4 can (and should) be
replaced with IPv6.
-
Third:
implementation, measurement, and simulation of TCP/IP networks will be
our focus on the practical aspects of computer networking - the
Labs.
My lectures WILL ASSUME that you have read related material
from one of the above books or other material (e.g., RFCs)
and thus that you come to class with
questions and some knowledge.
I plan on starting each lecture section with some questions and
concepts that you should be thinking about.
Requirements and Grades
I have no idea as to the best
approach to encourage you to submit material on time, except to use the
calendar and laboratory to try to control your activities and punish lateness.
Also, for a change I have a grader who will help in the lab,
hwks, etc.
But, I do plan on using the class to do some grading
and to present in class.
Thus, you will also be responsible for
some critical evaluation of your classmates' work.
I will be on campus only from Monday afternoon until Tuesday afternoon.
Like everyone at HMC,
I am on email almost all the time.
Feel free to come see me at any time, especially before or after class or lab.
Make sure to read the
late policy.
There WILL be one exam!! I hate exams for this type of material,
but multiple step problems
can demonstrate mastery of the material.
Your grade will be determined by your performance
on all assignments.
NOTE: historically it is the exam and 'lateness'
that determine the grade, i.e., almost everyone completes the weekly material.
The relative weighting scheme is:
Abstracts
Do them or lose the points.
There will be NO course grade of 'A' without
all abstracts being satisfactory completed.
Homeworks
Do them or lose the points.
There will be NO course grade of 'A' without
all homeworks being satisfactory completed.
I would love everyone to get every problem correct, but the goal of hwks is for you to learn.
A reasonable effort is what is necessary.
Be sure to show your work!!
Laboratory
The
laboratory aspect of this course will change as we progress.
There are over 20 different labs that we could use.
I will pick and choose as the semester moves forward.
Thus, the various Web pages will be updated as the semester progresses.
The labs focus on network investigation and code development.
Labs will have a statement about grades such as:
"Do parts 1 and 2 for a B; Do parts 1, 2, and 3 for an A".
Just make sure in your writeups that you indicate what work you think you have done.
Term Project
One thing that is certain is that each of you will
do a term project.
Whether that is a programming, writing,
or presentation is still an open question.
Collaboration Policy
Collaboration is encouraged. This means that you may
discuss approaches to solving problems
with anyone in the class,
including myself, graders, and other students.
However, copying solutions from any source (person or book) is
disallowed,
e.g., googling for information is fine, googling for the answer
is not. You are going to have to be mature enough to recognize the difference.
All students are expected to conduct themselves in
accordance with the Harvey Mudd Honor Code. If you have any questions
about what is appropriate or inappropriate collaboration, please talk
to Me.
Course Web Page
You should check the course Web page no less than every Sunday Evening
as you finally read something for the Monday lecture....
My plan is to
keep it updatedly weekly, i.e., by Sunday night the week should
be complete and subsequent weeks partially complete.
Things way out may move, but they do show you direction.
NOTE:
Everything is driven from the course Calendar, so keep checking it.
