Abstract
A communication system includes a source node including a first connection control register, a destination node including a second connection control register, and a controller. The controller is adapted to select one of a first and a second communication protocol as a communication protocol to be used between the source node and the destination node, to set a logical connection to be used between the source node and the destination node, to access the first connection control register to store therein information for the communication protocol selected by the controller and information for the logical connection set by the controller, and to access the second connection control register to store therein information for the communication protocol selected by the controller and information for the logical connection set by the controller. The first communication protocol uses an asynchronous transfer, but does not use an isochronous transfer.
