Abstract

See full text

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.
