Abstract of the Disclosure Method and apparatus for transfer of packet-type information from the memory of one node in a computer network to the memory of another node in the network. The invention is of particular utility in transfers over serial buses. Packets are sent from a named memory buffer at a first node to a named memory buffer at a second node allowing random access by the first node to the memory of the second node without either node having to have knowledge of the memory structure of the other, the source and destination buffer names are contained right in the transmitted packet. The first node can both write to and read from the second node. An opcode sent in each packet signifies whether a read or write operation is to be performed. For reading from the second node, the opcode actually causes the second node to write back to the first node; in this situation, the second node, upon detecting the appropriate opcode, places the remainder of the received packet on a command queue, to be executed with the commands locally generated at the second node, without need for host interruption.
