Abstract
The frame disassembly unit receives the MAC frame to insert/identify a destination address and tag. The information retrieval unit retrieves the VLAN information DB to discover the tag and port which correspond to the destination address. The type determination unit determines whether the MAC frame received is unicast, multicast or broadcast. The unicast transmission control unit controls the switching device so as to transmit the MAC frame to the communication node of the destination. The multicast transmission control unit controls the switching device so as to confine within a VLAN to transmit the MAC frame by multicast or broadcast.
