Check back every now and then for updates.

Add code:

15-16 spaces will be added to the class. Here are the rules:

- No Open University Add

- No add for students who are in other 206 session.

If you have an add code, you have to add within 24 hours (or earlier).


Class time:

Every Wednesday at 6:30pm <-----

Class room:

ENG 331


Initial creation.


Please consider how you set up your evaluation environments - be it homework, on-campus quizzes and exams, to minimize chances of (temptations to) cheating.

In particular:

During tests:

- Make sure there is plenty of space between students.

- Always proctor exams and tests, and preferably by sitting at the back of the room rather than at the front. Do not leave the testing room during the test. If you cannot proctor the class yourself, contact me and I will endeavor to find a proctor for you.

- If the test is closed-book, require all backpacks to be zipped shut, all PDAs, computers and phones to be handed in, and any access to either without explicit proctor permission should be an immediate F in the class.

For homework: We have started using on-line support systems to catch cheaters. So I would very strongly urge you:

- For code assignments: Run them all through MOSS

- For essays etc: Run them all through (SJSU has a site subscription, I have been told.)

- Make sure individual contributions are ensured in team projects. This can be done through various means: Sign-offs, quizzes on the content of common work, etc.

Remember: A grade reflects an evaluation of the individual student's achievements. Your evaluation system has to reflect that objective.

Class Material

Lecture Notes


Computer Networks: A Systems Approach, Fourth Edition.

As the first networking class, you do need the book and read as much as you can. Please do not use photocopy and observe copyright law. There will be reading assignments in almost every class and reading materials will be tested upon.

Non-Textbook: Reading material will be online on this web site before every lecture. Reading this semester:



Pick one of the references for term paper. Please spend the time to read and actually reseach (program) into the topics. The class expects a high quality research paper, not some collection of combined internet web pages ...

Term Project

Web PDA (Personal Digital Assistant)


The goal of the project is to give you explosure on real life development environment and network programming experience on the web. There are two parts into the term project. Part 1 is an individual part performed by one student and part 2 is a group part performed by four group members. The name of the project is called Web PDA (Personal Digital Assistant).

Part 1 - Information Portal (individual part)

Create an information portal in the form of a web site. This information portal allows a self-service creation of a USER. Each user can store various RESOURCES securely in the information portal. Here is a list of rerquirements:

Part 2 - Internet Information Exchange

Form a group of n and create a mechansim that allows n information portals to securely exchange information between real web sites. In other words, USERS from different web sites can exchange RESOURCE. The ideal size of n should be 4. As a group you must decide the following:


More info will be provided in the semester.



Project team has to decide on various issues such as:

As the whole class will be working on similar projects, relative grading will be used. In other words, all the projects will be ranked within the class and points will be assigned accordingly. There are two parts in the project:



Project Part I consists of a document includes the following:

Project Final Part will be covered later in class


Final Word of Warning

This is not an "easy" class and the project is an essential part of the overall grade. People who did not deliver the project well enough could really hurt their grade as the project contains more than 40% of the overall grade.

General Policy

The university and departmental policies and deadlines for course drop will be applied. Makeup exams cannot be offered, except under exceptional conditions, such as documented serious illness/accident, etc., and only at the professor's discretion.

Each student is responsible for his/her individual assignment, and must not copy anyone else's work. Students who borrow solutions from others will find themselves unable to pass the course. The minimum penalty for every student involved in the duplication of individual assignments or exams will be receiving a zero score on the submitted work.

For group project, all the work has to be done by your OWN group. Do not try to download "free code" from the Internet and hand in as a project. WE WILL FIND OUT. Do not share your work with others. So DO YOUR OWN WORK and EARN your grade.
