Abstract
Methods, systems, and apparatuses can provide improved bandwidth and reduction in processing resources in a cable system using bonded upstream channels. Physical or environmental changes can occur in the HFC network effecting communication performance on one or more upstream channels. For optimal HFC network performance periodic measurements and adjustments are made reducing HFC network bandwidth and consume processing resources. This periodic maintenance is performed even if the communication service is not using the additional upstream bandwidth provided through upstream channel bonding. Demand-based bonded upstream channel allocation and de-allocation provides additional upstream bandwidth when required while optimizing HFC network performance and reducing processing resources through the reduction of periodic measurements and adjustments on the HFC network.
