Abstract: Different polling rates are applied to high priority BE service flows depending on whether the service flow contains, or is about to contain, traffic packets. A high priority service flow is identified upon boot-up of a user device, and defaults to a slow polling mode. A trigger causes the service flow to be serviced as a fast polling mode. The fast polling mode lasts for a predetermined period of time. If traffic continues at the end of the predetermined period of time, the predetermined period of time is reset so that the fast-polling mode continues until traffic flow on the high priority service flow ceases.

Abstract: Static balancing of cable modems across upstream channels is made based on the channel's current bandwidth demand compared to a first and/or second CAC threshold level. If both threshold levels are exceeded, the modem is assigned to the channel having the lowest bandwidth demand. After registration, predictive balancing modems according to whether an MTA is part of a given modem avoids concentration of modems having MTAs on certain channels while other channels serve only moderns without MTAs. Modems are also predictively balanced according to whether they have associated a DSA_use_history profile. Modems associated with certain subscribers may be balanced according to the time of day balancing is occurring based on the profile. Thus, light users during working hours may be balanced as heavy users at night if they typically download video content or use VoIP features during the evening.

Abstract: A method and system that allow subscribers to a cable Internet data service to use a Web browser and access to the Internet via their cable Internet data service to dynamically change their service level by communicating with the cable modem manager that manages their cable modem. An alternate method and system allow a content provider that has been contacted by a subscriber to dynamically implement new “on-demand” services flows for the subscriber. With both arrangements, the subscriber can begin employing the new service flows without reinitializing their cable modem or otherwise having their data service disrupted.
