Abstract: An improved method of hierarchical output queueing of packets for a network scheduler of a network gateway that determines delays needed to conform to applicable rate shaping, and enqueues the packets based on the delay. Queues are associated with different classes of service (CoS), and within each class, each queue has a different scheduled time upon which it becomes available for dequeuing. A single set of CoS queues can support a large number of devices, improving the efficiency of software-based queuing by reducing the number of queues and simplifying queue polling.

Abstract: A pre-paid service system configured to provide a subscriber interface to a Subscriber and receive a service level selection from the subscriber, wherein the service level selection includes a capacity limit and/or a time limit. Upon authorization of a payment, the system activates the Subscriber's service. The system also monitors the Subscriber's usage data and time of activation. When the Subscriber's usage data amount or time of activation meets or exceeds the selected service level, the system may deactivate the Subscriber's service.
