In one embodiment, a method comprises recursively selecting a child node of a previously selected node of a port tree and having a highest priority among nodes of a same level within the port tree, until the selected node has associated egress queues of an egress port. The method also includes outputting a number of packets from the associated egress queues of the selected node in a current processing cycle. The number of packets outputted is based on an allocated bandwidth for the associated egress queues, in which the allocated bandwidth accounts for a deficit from a previous processing cycle.
