ABSTRACT:
A switching device for LAN is provided for switching packets in ETHERNET. The switching device includes an arrangement for storing the packet received at one of a plurality of receiving ports respectively connected to ETHERNET segments in a receiving buffer commonly used by the whole of the device, by means of a storage device of the receiving buffer. A transmitting destination port for the packet is determined through the use of an address filter device also common for the whole device. A transmitting buffer includes a storage device which receives the packet from the receiving buffer. Then, the packet is transferred from the storage device of the transmitting buffer to one of a plurality of transmitting ports corresponding to the determined address.
