It is defined by IEEE as 802.12. 100VG-AnyLAN uses a centrally controlled access method referred to as Demand Priority. This access method is a simple, deterministic request method that maximizes network efficiency by eliminating network collisions and token rotation delays. 10BASE-T. Therefore, it is more efficient. Repeater acts like a central network controller.
End node is like a computer or workstation or bridge.
It functions for exchanging data via the repeater. The basic structure of 100VG-AnyLAN is shown below. It is divided into several layers. Each layer has its own function which will be described below. Frames and errors checking can be done in this layer.
