CSMA/CD

This applet allows you to visualize how transmission time and propagation delay effect CSMA/CD. The applet uses a bus topology (such as with 10Base2) as opposed to a star topology (although similar effects occur with a star topology). The applet assumes a propagation speed of 2*10⁸ meters/sec.

1. Set the parameters: bus length, frame size, and transmission rate.

2. Click on Start.

3. Click on nodes to generate packets.

This applet was coded by Daniel Brushteyn in 1997 as part of course work at the University of Pennsylvania.
