SUBSCRIBER LOOP REMOTE CONTROL APPARATUS, SUBSCRIBER LOOP REMOTE CONTROLMETHOD, AND SUBSCRIBER LOOP REMOTE CONTROL PROGRAM

摘要

A subscriber loop remote control apparatus that allows communication terminals to transmit VLAN packets without imposing a load on a router. A subscriber loop remote control apparatus is provided with a virtual interface table for associating a subscriber premises terminal identifier individually assigned to a subscriber premises terminal connected through a communication cable to a port assigned to every packet of each group which constitutes a VLAN with the port number of the port to store and manage them. When receiving a packet, the subscriber loop remote control apparatus determines whether or not a subscriber premises terminal identifier contained in the packet matches any of those in the virtual interface table. When the subscriber premises terminal identifier matches one of those in the virtual interface table, the subscriber loop remote control apparatus returns and transmits the packet to the destination before the router side.
