Abstract
The present invention teaches methods and systems for subscriber blocking of unauthorized network traffic in a cable data network. The cable modem termination system (CMTS) incorporates a data gateway agent that filters unauthorized traffic thereby eliminating consumption based subscribers from being responsible for related service charges. Embodiments incorporate the use of packet filtering, hybrid stateful packet filtering, content filtering, application layer filtering and time based filtering. Greater acceptance of consumption based billing is achieved by having the filter settings directed by the subscriber.
