Abstract
In various embodiments, a method, computer-readable storage medium, and apparatus for scheduling prioritized best effort (BE) service flows through a wireless network base station includes a controller coupled to a memory. If any one of a plurality of BE service flows are congested, a minimum reserved traffic rate (MRTR) algorithm is used by the controller to ensure that at least a highest priority BE service flow is maintained at least at an associated MRTR. If none of the plurality of BE service flows are congested, a maximum sustained traffic rate (MSTR) algorithm is used by the controller to enable the highest priority BE service flow to be set to at least at an associated MSTR before lower priority service flows are increased. If none of the plurality of BE service flows are congested and each service flow is at their associated MSTR, the controller is configured to distribute any excess bandwidth to each service flow in accordance with an initial set of priority BE traffic flow ratios.
