ABSTRACT:
A computer system executes an application that requires transfer of data to or from the computer system. The system responds to requests from the application, by allocating storage for a data buffer, verifying that the application is authorized to access the buffer, converting an address of the buffer utilized by the application to a corresponding system address and mapping the system buffer address to an index. The system also responds to a subsequent transmit or receive request from the application, by accessing the data buffer based on the index such that no storage allocation, address conversion, or access verification is required for the transmit or receive request after the transmit or receive request is made. The computer system includes a communications adapter at an input or output port and the data is transferred between the communications adapter and the buffer without any intermediary buffering. Thus, the transmit and receive requests are processed expeditiously.
