A method for dynamic power reduction management of network devices comprising: monitoring traffic flow at a customer premise equipment device, wherein the traffic flow is monitored by the customer premise equipment device; in response to a quality of service change, comparing the monitored traffic flow to a plurality of predetermined traffic flow thresholds, wherein each respective traffic flow threshold is associated with a channel set size capable of supporting traffic that is below the respective traffic flow threshold; identifying a traffic flow threshold that is greater than the monitored traffic flow, wherein the identified traffic flow is the lowest traffic flow threshold of a subset of the plurality of predetermined traffic flow thresholds, the subset including one or more traffic flow thresholds that are greater than the monitored traffic flow; if the monitored traffic flow at the customer premise equipment device is less than the identified traffic flow threshold for a predetermined period of time, outputting a request that the customer premise equipment device be provided a channel set having a size equivalent to the channel set size associated with the identified traffic flow threshold, wherein the requested channel set size is smaller than the channel set currently provided to the customer premise equipment device, wherein the request comprises a cable modem status message that identifies the channel set size associated with the identified traffic flow threshold; receiving an updated channel set in response to the request, wherein the updated channel set has a channel set size equivalent to the channel set size identified by the request; and limiting one or more resources at the customer premise equipment device that are not needed to support the updated channel set, wherein limiting one or more resources at the customer premise equipment device comprises powering down the one or more resources, wherein the one or more resources that are powered down are resources dedicated to the reception or transmission of a channel that is no longer required as a result of the updated channel set. monitoring traffic flow at a customer premise equipment device, wherein the traffic flow is monitored by the customer premise equipment device; in response to a quality of service change, comparing the monitored traffic flow to a plurality of predetermined traffic flow thresholds, wherein each respective traffic flow threshold is associated with a channel set size capable of supporting traffic that is below the respective traffic flow threshold; identifying a traffic flow threshold that is greater than the monitored traffic flow, wherein the identified traffic flow is the lowest traffic flow threshold of a subset of the plurality of predetermined traffic flow thresholds, the subset including one or more traffic flow thresholds that are greater than the monitored traffic flow; if the monitored traffic flow at the customer premise equipment device is less than the identified traffic flow threshold for a predetermined period of time, outputting a request that the customer premise equipment device be provided a channel set having a size equivalent to the channel set size associated with the identified traffic flow threshold, wherein the requested channel set size is smaller than the channel set currently provided to the customer premise equipment device, wherein the request comprises a cable modem status message that identifies the channel set size associated with the identified traffic flow threshold; receiving an updated channel set in response to the request, wherein the updated channel set has a channel set size equivalent to the channel set size identified by the request; and limiting one or more resources at the customer premise equipment device that are not needed to support the updated channel set, wherein limiting one or more resources at the customer premise equipment device comprises powering down the one or more resources, wherein the one or more resources that are powered down are resources dedicated to the reception or transmission of a channel that is no longer required as a result of the updated channel set.
