Abstract
A transparent routing device disposed within an access network configured in accordance with one or more lower-layer protocols is disclosed herein. The device includes a set of subscriber-side ports. Each of the subscriber-side ports is associated with a plurality of virtual subscriber-side interfaces disposed to effectively terminate a corresponding plurality of subscriber-side connections with subscriber host devices served by the access network. The device further includes at least one network-side port through which communication occurs with an external network in accordance with a higher-layer protocol. A routing table is configured to establish a correspondence between network addresses of the subscriber host devices and the plurality of virtual subscriber-side interfaces. During operation of the device, packets received through the at least one network-side port are forwarded to corresponding ones of the virtual subscriber-side interfaces based upon network addresses of the packets.
