ABSTRACT:
A method for providing remote direct memory access (RDMA) between two computers, preferably between central processing units (CPUs) and a functional subsystem of a computer system as part of their network communication, e.g. using TCP/IP. Tasks of analyzing network protocol data and the actual RDMA operations can be offloaded to the functional subsystem with this method. Further, the functional subsystem cannot compromise the status of the first computer system as only access to certain allowed memory locations is granted by a memory protection unit during phases of actual data transfer between the functional subsystem and the CPUs.
