An apparatus, method and computer program for processing packets in a peripheral component interconnect express (PCIe) network provide means for receiving a PCIe posted write packet at a receiving device, the PCIe posted write packet including a received tag identifier and a requesting device identifier identifying a requesting device. An expected tag identifier is determined for the requesting device. The received tag identifier is compared to the expected tag identifier. An error flag is set if the received tag identifier does not match the expected tag identifier.
