In the method, data are transmitted between a first memory allocated to a source computer and a second memory allocated to a target computer via a network by remote direct memory access. On the source computer side, a predetermined number of directly consecutive transmission buffers is selected from a continuous buffer memory area and transmitted in a single RDMA transmission process to the target computer. On the target computer side, an RDMA data transfer is executed over the entire continuous buffer memory area and a buffer sequence procedure. The buffer sequence procedure causes the received buffers to be supplied to the target application in the transmitted sequence.
