Abstract
A data processing network and method of operation thereof are provided for efficient transfer of ordered data from a Request Node to a target node. The Request Node send write requests to a Home Node and the Home Node responds to a first write request when resources have been allocated the Home Node. The Request Node then sends the data to the written. The Home Node also responds with a completion message when a coherency action has been performed at the Home Node. The Request Node acknowledges receipt of the completion message with a completion acknowledgement message that is not sent until completion messages have been received for all write requests older than the first write request for the ordered data, thereby maintaining data order. Following receipt of the completion acknowledgement for the first write request, the Home Node sends the data to be written to the target node.
