Projects

For individual or a team of two. For graduate students, there are two required projects. Both are closely related to the information literacy program sponsored by the CSU library. A detailed grading rubric will be provided for each project. As a way to gain extra-credit, you are encouraged to build demonstration programs (Java applet, plain Java application, or use NS2 simulator). Project #1 is waived for undergraduate students.

 

Project #1: Select a topic in Chapters 1, 3, and 7, and build a wiki page for the topic on http://www.pbwiki.com/. Example topics are: Introduction to computer networks, Internet history, ISO/OSI reference model, TCP/IP model, World Wide Web, HTTP, DSN, Data link layer design principles.

Project #2: Select a topic in Chapters 4, 5, 6, and build a wiki page for the topic on http://www.pbwiki.com/. Example topics are: Static channel allocation, dynamic channel allocation, multiple access protocols (Aloha, CSMA etc.), Ethernet, ARP, DHCP, network layer, routing algorithms (link state and distance vector), IP, TCP, UDP, ICMP, reliable communication protocols, sliding window protocols.

As part of Project #2, peer-review and revision steps are involved. Each team is required to review three wiki pages built by other teams anonymously. The quality of the review will be counted towards the total credit for this project. Furthermore, after getting a set of reviews, each team must address the comments and revise its wiki page carefully in light of the reviews. If the team disagrees with any comment, a convincing argument should be provided to refute it.

 

Quizzes

There is no makeup quiz. Each quiz is designed for one-hour completion, but you have up to 1 hour and 50 minutes to complete it. The quizzes are closed book and closed notes, except that you are allowed to bring with you a one-page cheat sheet not larger than the US letter size (double-sided allowed).

 

To improve your credit on the quizzes,

(1)   The weight of the best quiz is doubled

(2)   The weight of the worst quiz is halved

 

Labs

There are 5 lab sessions on HTTP, DNS, Ethernet & DHCP, IP, and TCP. They are all based on the Ethereal tool. The labs are mandatory. There will be no makeup lab, and no extension will be granted for lab reports. Exception may be granted to those who have strong background to complete the labs without my supervision (in which case, you do not have to show up during the designated lab sessions. However, lab reports are still required). If you are granted an exception, the related requirement on the lab session attendance for class participation credit is automatically removed.

 

Class Participation

10% of the course credit is allocated to encourage student class participation. I may perform a roll call in the beginning of each class to determine the attendance. To obtain the full credit for class participation, you must satisfy the following conditions:

  • You do not miss more than 2 lectures
  • You do not miss any quiz and lab sessions (if you choose to the labs option)
  • You have asked at least 10 questions during the semester. You are also encouraged to give me advice on how you would like me to improve my teaching to make it more conducive. For each piece of advice, it will be counted as 2 questions.

To help me keep track who asked me questions, please send me an email with the following information for each question you have asked within 24 hours after the lecture:

  • The question you asked
  • My response
  • Your comment on my response and suggestion for improvement, if any

 

Grading

For graduate students:

−        Class participation 10%

−        Quizzes 40%

−        Labs (20%)

−        Projects (30% [project#1 10%, project#2 20%])

For undergraduate students:

−        Class participation 10%

−        Quizzes 40%

−        Labs (30%)

−        Projects (20%)

 

 

The final grading is based on your accumulated effort in this course. Your final grade is determined approximately based on the following schedule:

A: 90-100%

A-: 85-89%

B+: 75-84%

B: 65-74%

B-: 60-64%

C: 50-59%

D: 40-49% (undergraduate only)

F: (<50% for graduate students; <40% for undergraduate students)
