Abstract :
In an HFC network, the upstream bandwidth, which subscribers use to send a variety of traffic, is entirely allocated by the headend. Some of the traffic classes (such as voice) only use a part of their allocated bandwidth, thus there is redundant bandwidth. This paper describes a method that uses the redundant bandwidth to transmit other traffic classes so as to increase the utilization of the upstream bandwidth
