In one embodiment, a router that accesses a cable network through a cable modem receives, from the cable modem, a plurality of service-flow classifications utilized by the cable modem to describe service flows on the cable network. Based on the received service-flow classifications from the cable modem, the router determines traffic destined for the cable network that corresponds to each service-flow on the cable network. The router receives, from the cable modem, an indication of network backpressure for a particular service-flow on the cable network. The indication of network backpressure is received when a threshold of network backpressure has been surpassed for the particular service-flow on the cable network. The router controls particular traffic that corresponds to the particular service-flow on the cable network based on the indication of network backpressure for the particular service-flow on the cable network.

Applying router quality of service on a cable modem interface on a per-service-flow basis

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.
