COMMUNICATION SYSTEM WHEREIN AFTER A REQUEST, DATA IS TRANSFERRED FROM A FIRST NODE TO A SECOND NODE THROUGH A CONTROLLER AND ACKNOWLEDGEMENT IS MADE BY THE NODES WHEN THE DATA IS RECEIVED

摘要

A communication system is provided for communication between network nodes and a communication controller. In the network, a request signal is transmitted from a first node to the communication controller to allow communication with a second node. After grant of the request by the controller, the first node sends its data through the communication controller to the second node. The second node sends an acknowledgement through the communication controller to the first node once the data message is received. The first node then acknowledges receipt of the acknowledgment by the second node.
