摘要：A system and method are disclosed to provide an interface between anemulator and a network that is readily scalable. In one aspect, a scalable solution isachieved through a hardware interface board positioned between the network and theemulator to allow proper transfer there between. A computer is separated from andcoupled to the hardware interface board and provides the necessary control signals.Because it is done in hardware separated from the computer, the interface board isreadily scalable through the simple addition of network chip sets. In another aspect, theinterface board can be placed in two modes of operation. One is a live test wherein theemulator and network communicate through the interface board, without the need totraverse a computer. A second is a direct test where the network is electricallydisconnected from the emulator, and an application program on the computer sendspackets directly to the emulator through the interface board. In yet another aspect,packet formats may be changed on the interface board so that it appears to the
emulator as if the network is operating at a different data transfer speed than is actually
the case.
