Abstract

See full text

In one embodiment, a cable modem determines network backpressure per service-flow, and transmits the network backpressure per service-flow to a router (e.g., co-located on a same network device). Also, the cable modem may transmit service-flow classifications to the router, such that the router may then control traffic per service-flow based on the network backpressure per service-flow, accordingly.
