A node comprises a first agent, a second agent, and a third agent, all coupled to an interconnect. The first agent is configured to initiate a transaction on the interconnect to transfer a coherency block to the second agent. The third agent is configured to transmit the coherency block on the interconnect during a data portion of the transaction instead of the first agent responsive to a state of the coherency block in the third agent. In some embodiments, the first agent may be designated to store the node state of a remote cache block, and the second agent may be responsible for internode coherency within the node.
