摘要
Mechanisms are provided for instigating the sending of an acknowledgement response from a host system. A buffer of a data processing system is monitored to determine if there is a data transfer pending in the buffer. In response to a determination that there are no data transfers pending in the buffer, a determination is made as to whether there is an outstanding data transfer, on a corresponding network connection with the host system, for which an acknowledgement response has not been received from the host system. In response to a determination that there is an outstanding data transfer for which an acknowledgement response has not been received, an acknowledgement instigation message is sent to the host system to instigate the host system sending an acknowledgement response for the outstanding data transfer.
