ABSTRACT:
A local network interface is used in a network for enabling each of a plurality of data processing stations to communicate with one another via a communications medium. The local network interface is connected between the communications medium and the data processing stations. The local network interface includes a processor, a direct memory access (DMA) controller connected to the processor, means for controlling communications connected between the communications medium and the processor, and memory means which is connected to the processor, to the means for controlling communications, and to the DMA controller. Data residing in the memory means may be accessed for transmission to, and may be updated from, the communications medium via the local network interface.
