Abstract
A method and a correspondingly designed device for data transfer in a computer network, the method including transmitting a first message addressed by a first node of the computer network to a second node of the computer network for requesting information regarding the synchronicity of the second node with an element of the computer network, receiving a second message addressed by the second node of the computer network to the first node of the computer network with information regarding the synchronicity of the second node with the element, and ascertaining a status of the synchronization of the second node with the element with the aid of the received information.
