Abstract
This paper designed a virtual experiment system for computer network curriculum with Dynamips. First this paper introduced the Dynampis function and running mode. Then this paper designed the system modules. Finally this paper implemented the Dynamips with Flex and Applet. And system testing shows the virtual experiment system satisfy the network simulation function as the system designed. The remote courseware virtual experiment system had a great practice value in the teaching and leaning process of the computer network curriculum.
Highlights
Experimenting is a major step in scientific research, and an essential part in teaching, especially in colleges and universities
For a computer network virtual experiment system, users can be divided into three categories: students, teachers, and guests
The implementation of the remote connection to the Dynamips virtual machine is based on an Applet Telnet client
Summary
Experimenting is a major step in scientific research, and an essential part in teaching, especially in colleges and universities. Dynamips mainly have the following three functions: (1) The simulator can be used as a training platform to help students become familiar with Cisco network equipment with little cost. This training will reach the goals of using real equipment. Dyanmips can simulate a Cisco router after compiling its runs in two modes: the first is host based and the other is set up with a virtual machine management port through hypervisor. The disadvantages are when one of the virtual machine collapses, it will endanger the whole platform to collapse and the supervisor mode needs to install Python to run Dynamips This project chose the host-based mode because of its high equipment usage efficiency
