Abstract of the Disclosure A message transfer arrangement includes a client node and a server node interconnected by a data link. The client node sequentially receives requests from user applications and generates, in response to each request, command messages for transmission by said interface, each command message including a command and having a transmit slot identifier identifying the request in the sequence of requests received by said request receiver and a transmit sequence identifier identifying the command message in the sequence of command messages relating to the request. The selection of whether to transmit a command message related to one request or to a subsequent request is based on a received slot identifier and a received sequence identifier in a response message. The server node receives command messages from, and transmits response messages to, the client node over the data link. It selectively executes the command contained in each command message and generates, in response thereto, a response message including a response slot identifier and response sequence identifier corresponding to the command slot identifier and command sequence identifier. The determination of whether to execute a command in a command message is based on the command slot identifier and command sequence identifier of the received command message received by interface and the command slot identifier and command sequence identifier of the command message containing the previously executed command.
