Abstract: In a computer network including a first computer communicatively coupled with at least a second computer through data and control channels, wherein each of the first and second computers are provided with an application program, a communication program and a synchronization program. In each of the first and second computers, the communication program is provided between the application program and the data and control channels, while the synchronization program is provided between the application program and the communication program. The synchronization program including means for sequentially forwarding commands and data units received from the application program of the same computer to the communication program of the same computer for transmission to another computer as corresponding control and data signals on the control and data channels, respectively.
