System and method for transparent virtual routing
First Claim
1. A method of providing differentiated quality of service within an access network in communication with an upstream network, said method comprising:
- disposing a transparent virtual router within said access network, said transparent virtual router being in communication with said upstream network;
defining, by said transparent virtual router, a plurality of virtual subscriber-side interfaces disposed to effectively terminate a corresponding plurality of subscriber-side connections with a plurality of subscriber host devices served by the access network;
defining, by said transparent virtual router, first and second network-side connections between the access network and the upstream network, said first network-side connection being associated with a first quality of service and said second network-side connection being associated with a second quality of service;
receiving, by said transparent virtual router, internet protocol (IP) data packets from the plurality of subscriber host devices via the corresponding plurality of virtual subscriber-side interfaces;
classifying, by said transparent virtual router, the IP data packets received from each of the plurality of virtual subscriber-side interface into a first set of IP data packets that are characterized by said first quality of service and a second set of IP data packets that are characterized by said second quality of service;
redirecting, by said transparent virtual router, said first set of IP data packets of the received IP data packets to said first network-side connection; and
redirecting, by said transparent virtual router, said second set of IP data packets of the received IP data packets to said second network-side connection.

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.
