Abstract

Telelearning is a collection of strategies and techniques for instruction at a distance. With the relatively recent success of the Internet and its almost universal accessibility, the web has become a very attractive vehicle for the delivery of courses. Depending on the course content and the amount of synchronous interaction between students, the amount of network traffic can vary tremendously—and this can have a huge impact on the quality of service (QoS) experienced by the system users. Thus, in planning to deliver courses, network administrators and course designers need answers to the following questions: (1) What is the “capacity” for a given system configuration and QoS criteria? (2) What is the effect of changing the course content on the QoS? (3) How do the critical resources in the system affect the overall QoS? (4) What is the most effective systems architecture? (5) What system resources need to be present to offer a course.

The answer to each of these questions can be quite complicated, since systems have many parameters and each user will interact with the environment in unique and often complicated ways.

This thesis describes our efforts to answer these questions with the OPNET computer simulation package. (Abstract shortened by UMI.)
