Timings and Room:

Texts:

• Computer Networking by James Kurose and Keith Ross, Addison Wesley, 3rd Edition, (ISBN 0-32-122735-2), 2004
• Core J2ME Technology and MIDP by John W. Muchow. Prentice Hall / Sun Microsystems Press (ISBN 0-13-066911-3), 2002 - out of print?
• Opnet material
• In addition, we may refer to research papers.

Additional Recommended Texts:

• Computer Networks by Mohsen Guizani, soon to be published
• NS-2 documentation

Prerequisites:

• Strong desire, self-motivation & dedication to learn & contribute to area of computer networks
• Proficient in C, C++ and Java (especially network programming)
• Low-level, systems programming and Linux programming experience
• Some mathematics and statistics background
• CS224 and CS331

Course Objectives:

1. Understanding of basic networking protocols (ex. CSMA/CD)
2. Knowledge of network layering (ISO OSI) and basic protocol stack(s)
3. Learn internetworking and high level utilities (FTP, HTTP, etc.)
4. Basic understaning of network security and encryption (ex. HTTPS)
5. Network programming with Java (TCP/UDP sockets, clients, servers)
6. Network simulations with OPNET, NS2.

Computer usage: Students complete 4-6 assignments during the semster.

Performance Objectives:

1. Students will be able to describe and distinguish basic networking
   protocols and understand where each is useful and why
2. Students will know the relationship between the 7 ISO OSI network layers,
   to include the involvement and support provided by each in transmission
3. Students will know and be able to understand programming logic for
   several high level utilities, including a FTP client and WWW server
4. Students will have a basic understaning of network security and
   encryption protocols such as HTTPS
5. Students will be able to write simple network programs in Java
   involving TCP and UDP sockets, URL connections, and interfaces
6. Students will be able to write simple network simulations using OPNET and/or NS2.

Topics (in no particular order):

1. Protocols, topology; packet switching; terms

2. Applications, clients, servers; HTTP, FTP, Email, DNS

3. Transport: TCP, UDP unicast

4. Network layer and routing; IP 4,6

5. Encoding; point-to-point; error handling

6. Ethernet 802.3, 802.11b Bluetooth SNMP

7. Encryption, security, compression; forward error correction

8. Multimedia, IP multicast

Grading:

     During the term there will be two examinations, a number of pop-quizzes, and class presentations. In addition, there will be assignments outside of class, programming and written. These components will carry the following weights in computing an overall average (if one of the components is not covered adequately its weightage may be transferred to other components):

• Examination 1 (tentative, Tuesday, 2/22/05)  30%
• Examination 2 (tentative, Monday, 4/18/05, 8:00-10:00am) 30%
• In-Class Pop-quizzes 10%
• Home Works (approximately 4-6) 30%

     The following minimum averages are required to guarantee the indicated grade. While the scale may be changed slightly, it will be changed to your benefit. A - 90; BA - 85; B - 80; CB - 75; C - 70; DC - 65; D- 60.

     Incomplete grades Please note that the incomplete grade - 'I' is intended for the students who has missed a relatively small portion of work due to circumstances beyond his/her control. In general, performance on work done must be at a level of C or better in order to qualify for an incomplete. An I grade will not be given to replace a low or failing grade in a class.

Minimum Passing Requirement:

Class Policies:

   In general, there will be NO make ups for the exams. If you miss an exam for a VALID reason, then arrangements may be made on an individual basis. Home works and programs are to be submitted at the class time on the due date. There will be a late penalty of 5% per day including weekends. Home works and programs will not be graded after 10 days including weekends (unless prior arrangement is made because of illness etc.) All home works and programs should be turned in, however, to pass the course. Confirmed cheating on an exam will result in an automatic E for the course. All programming and homework assignments are to be completed individually. Collaboration on the programming and homework assignments is also considered cheating. Identical programs, look-alike, or obvious joint efforts will result in an E grade for all involved. Note that it is your responsibility to protect your work so that others will not copy it.

  You are expected to stay alert and pay attention to the directions/announcements in the class. Cellphones, PDAs, and other electronic devices should NOT be used during the lecture and should be turned-off. If available, please do bring your laptop to the class. Web-surfing of non-course related material is NOT permitted during the class. You may surf the web only when specifically told to do so. In order to maintain the integrity of the classroom and if I feel it is distracting you or others, I may ask you to turn-off your laptop.

Dropping of Class:

Academic Integrity and Honesty:

In this course, you are expected to submit only your work for credit or exams, unless a project or activity has been made to groups, in which case the group is to submit only work done by members of the group. Unless otherwise told, you may not bring aids to exam. Submission of another person's work as your own in part or whole is not permitted and can result in a failing grade for the class. Learning can certainly occur with discussion of class material and assignments with other students, but take care that you don't represent the work of another as your own. If you are copying portions of someone else's work, either by hand or electronically, you are going too far. If two or more people are working so closely together that the outcomes, particularly computer programs, are essentially line by line the same, you are going too far. If you are found responsible for academic dishonesty under the University policy, you will receive a failing grade in the class.

Additional Note: Easy availability of information, material, source codes, lecture notes etc on the Internet may make it possible to find solutions to your assignments on the Internet or elsewhere. It is okay to refer to those, understand them and use them to enhance your solutions, generate your own ideas etc. However, you must give proper and full credit to original authors of the work, if you include their ideas and/or solutions. Failing to do so is part of academic and professional dishonesty. It will not be tolerated in this class. Do not give in to temptations..
