Title: Method and device for controlling data transmission

Abstract: A method for controlling data transmission in a network system configured by a first node, a second node, and a third node. The first node has a first port connected to the second node and a second port connected to the third node. The first node enables data received by the first port from the second node to be transmitted by the second port to the third node. The received data includes information of the node to which the received data is addressed. The method compares the information of the first node with the address information included in the received data, temporarily disconnects the third node from the first node when the received data is not addressed to the third node.
