Abstract
The downstream IP packets of uni-cast services, such as Internet Access or Voice over IP network, are transported over the pseudo wire from service provider nodes at the metro hub to the access edge, whereupon they are converted to be transported on the first mile technology, such as a DSL loop, that serves the subscriber's residence. A television service provider delivers the collection of television channels through the regional network to an intermediate node, herein called the metro edge device. The function of the metro edge for downstream uni-cast traffic is to de-multiplex the downstream pseudo-wires coming on packet trunks from metro hubs, into a greater number of packet trunks leading to access edges. In this invention the metro edge device is operable to unicast individual selected channels to the subscriber's residence by adding copies of the IP packets of the selected channels into the downstream flow of packets in the subscriber's pseudo wire.
