What are the commonly used access control technologies in LAN?

There are three commonly used access control methods in LAN, namely carrier multiple access/collision detection (CSMA/CD), token ring access control method and Toking bus access control method.

Applicable to:

CSMA/ CD access control mode is mainly used in bus and tree network topology and baseband transmission system, and is suitable for bus LAN.

The medium access control method of token ring is to realize medium access control by transmitting tokens on the ring network;

Token bus access control method is mainly used in bus or tree network structure, and it is the mainstream medium access control method in microcomputer local area network at present.
