| 20080294810 | Response control method and device - When a device in a WUSB system is ready for transmission data upon reception of a data transmission request (WdtCTA) from a host device, the device outputs the transmission data at a time specified by the WdtCTA. Meanwhile, when the transmission data is not ready, the device estimates a preparation completion time for the transmission data, and when the estimated preparation completion time is before an earliest time at which the host device can retransmit the WdtCTA, the device sends an error response instead of a NAK response, to thereby request the host device to retransmit the WdtCTA. As a result, a data transmission efficiency between the host device and the device is improved. | 11-27-2008 |
| 20100036982 | INTERROGATE PROCESSING FOR COMPLEX I/O LINK - A method for facilitating input/output (I/O) communication for a processing operation is provided. An interrogate command is obtained by an I/O communications adapter. The interrogate command queries for status information of the processing operation to be provided in an interrogate response. A fixed number of resources and a time allocated to the interrogate command is throttled by pre-allocating the fixed number of resources needed for the interrogate command, and maintaining a timestamp for a interrogate message. The interrogate message is forwarded from the I/O communications adapter to a control unit. If the interrogate response is not received by the I/O communications adapter within a limited timeout period as measured by the timestamp, or if the interrogate message is received while the fixed number of pre-allocated resources are in use, the I/O communications adapter returns a busy response indicating the control unit is busy to prevent overrunning the control unit. | 02-11-2010 |
