Method and apparatus for acknowledging a request for data transfer

摘要

The disclosed embodiments relate to an apparatus and method for acknowledging a data transfer. The first protocol may generate a request for a data transfer. The second protocol may receive the request for a data transfer from the first protocol. With the request, the second protocol may determine if the request for the data transfer contains a request for acknowledgement of completion of the data transfer. The second protocol may send a request corresponding to the request for data transfer to a third protocol. If the request for data transfer does contain a request for acknowledgement of completion of the data transfer, then the second protocol may set a variable in memory to wait for an event to correspond to the completion of the request and send an acknowledgement to the first protocol upon the occurrence of the event.

主权项

1. An apparatus for acknowledging a data transfer, comprising:
a processor configured to transfer data according to a plurality of protocols of a protocol stack, the protocol stack comprising: a first protocol layer to initiate a request for a data transfer; and a second protocol layer to:
receive the request for the data transfer from the first protocol layer;determine whether the request for the data transfer contains a request from the first protocol layer for acknowledgement by the second protocol layer of completion of the data transfer;send a performance request for completion of the data transfer to a third protocol layer; andin response to a determination that the request for the data transfer does contain the request from the first protocol layer for acknowledgement by the second protocol layer of the completion of the data transfer:
set a variable in memory to wait for an event corresponding to the completion of the request for data transfer; andgenerate and send an acknowledgement to the first protocol layer upon the occurrence of the event.
