Abstract

Methods for allocating bandwidth among MCR and best effort connections include listing MCR connections in an MCR service list and best efforts connection in a best efforts (BE) service list. Assigning an MCR value to each MCR connection and setting a Cell Count Register (CCR) with it. During a service interval, dequeueing each MCR connection queue in round robin fashion according to the MCR service list and decrementing the associated CCR. If the CCR reaches zero before the end of the service interval and there are still cells in the queue, the connection is moved from the MCR service list to the BE service list for the remainder of the service interval. If the CCR reaches zero before the end of the service interval and/or there are no cells remaining in the queue, the connection is removed from the MCR service list. If all of the cell counts reach zero and/or if all of the MCR queues become empty before the end of the service interval, the connections on the BE service list are serviced by a separate scheduler. At the end of the service interval, the CCRs are reinitialized and the MCR connections which were moved to the BE service list are moved back to the MCR service list.
