Abstract
A computer implemented method and apparatus are provided for transferring data in a logical partitioned data processing system. A receiving adapter receives data from a network. The receiving adapter transfers the data to a pre-mapped buffer if the data is to be sent to a target adapter. A virtual bridge receives the pre-mapped buffer from the receiving adapter and transfers the pre-mapped buffer to the target adapter. The target adapter receives the pre-mapped buffer from the virtual bridge and determines that the received buffer is pre-mapped. The target adapter accesses the pre-mapped buffer using pre-mapped mapping, and transmits the data contained therein.
