Abstract
An upstream bandwidth allocation scheduler is provided for use within a Line Termination (LT) unit in a point to multi-point data communications network in order to service multiple Network Termination (NT) units. The scheduler first allocates bandwidth among the several categories of data handled by the network (e.g., voice, IP, and ATM data), and then allocates bandwidth among the several users for each category within the network. A function ƒ is defined, as part of a “min-max weighted fairness” scheme, in order to allocate surplus bandwidth among both the categories and users of the network. The scheduler of the present invention, while allocating upstream bandwidth, also supports various quality of service (QoS) categories to subscribers of the network.
