In a token ring network, all workstations are connected in a ring or star topology and a token-passing scheme is used to prevent the collision between two workstations who want to send messages at the same time. Here, very briefly, is how it works:
The applet on this page is a simple simulation of a token ring network with four computers, one can see an animation of this network, with messages travelling between computers, and at the right of this animation is a representation of the event set. The blue line denotes the event that is taking place, the next lines denote future events that have been scheduled, the future event set. Under the animation one can see the simulation time which can be speeded up, or slowed down using the arrows at the bottom.
