Computer Network Experiments, Spring 2010

Instructor: Prof. Ying-Dar Lin,

Course Objective: 

        This undergraduate course aims to reinforce the knowledge and skills taught in the traditional computer network courses. A series of experiments are designed to get students well exposed to the protocol issues ranging from the overall networking hardware and software architectures, adaptor and protocol drivers, LAN MAC protocols, TCP/IP protocol suite, to planning and configuration of LAN and WAN.

Experiments are to be done by 2-person teams. Each team needs to conduct 6 experiments where 3 of them are pre-selected (see * in the list below) and 3 are chosen by students. For each experiment report and presentation, the student in charge of writing up the report receives up to 18 points, while his/her teammate receives up to 9 points, thus the 6 experiment reports account for 81 points, i.e. 3x18+3x9.. The report should cover experiment records and problem discussions. Students need to present their experiment reports within 3 weeks after the lecture of the experiment. Each in-class presentation is allocated 15 minutes. At the end of the semester, a hands-on individual (not in a team) quiz accounts for 19 points. In the hands-on quiz, the TA picks 3 questions, on the experiments a student has done, for the student to operate and explain on the computer or testbed. A mail alias,, is established to facilitate the after-class discussions.
