Ensure Upstream Channel Quality Measurement Stability In An Upstream Channel Bonding System Using T4 Timeout Multiplier

A computing device, comprising:

• a memory device resident in the computing device;
• and
• a processor disposed in communication with the memory device, the processor configured to:
• configure a cable modem, that communicates using bonded channels, to periodically exchange ranging messages on the bonded channels, wherein a bonded channel ranging interval determines a period for the exchange;
• monitor a signal quality metric for a monitored channel of the bonded channels by periodically retrieving a quality measurement for the monitored channel, a period between each retrieval determined by a channel quality monitoring interval;
• send an invite ranging message to the cable modem before retrieval of the quality measurement for the monitored channel;
• and
• retrieve the quality measurement for the monitored channel, wherein the signal quality metric for the monitored channel is based on the quality measurement.

A non-transitory computer-readable medium, comprising computer-executable instructions that, when executed on a computing device, perform steps of:

• configuring a cable modem, that communicates using bonded channels, to periodically exchange ranging messages on the bonded channels, wherein a bonded channel ranging interval determines a period for the exchange;
• monitoring a signal quality metric for a monitored channel of the bonded channels by periodically retrieving a quality measurement for the monitored channel, a period between each retrieval determined by a channel quality monitoring interval;
• sending an invite ranging message to the cable modem before retrieval of the quality measurement for the monitored channel;
• and
• retrieving the quality measurement for the monitored channel, wherein the signal quality metric for the monitored channel is based on the quality measurement.
