The Data-Link Layer and Access Control. Access control strategies offer various solutions to this problem. Access Control Strategies. The technology based on it is called Ethernet. The strategy allows the network to be used most heavily because more than one device can attempt to transmit at once.
Collisions are the result.
If so, wait. Multiple Access - Several devices can be checking the wire or attempting to transmit at the same time . With this strategy in order to transmit, a device must possess the token. Technologies based on this include FDDI, CDDI, and Token Ring. All other devices, without the token, cannot transmit.
