Abstract
In a network communications system, data is transferred from a first node to a second node. When requested, the second node can transmit a data direction turnaround message to the first node, followed by transferring data to the first node. Data transfer in both directions is made during a single communications link within the network. The turnaround message can function as an acknowledgement of successful transfer to the data transferred from the first node to the second node.
