Abstract
A technique for controlling a multiplicity of time-sorted queues with a single controller and supporting memory, which may be software-configured so as to allow the use of the controller in an implementation having a multiplicity and variety of output lines or channels. The technique includes receiving a plurality of packets from one or more packet flows at a respective time-based output port queue of the network switch, in which each packet has a timestamp associated therewith. Each output card memory can be divided into a plurality of queues, in which the number of queues corresponds to the number of flows received by the switch and the size of each queue is proportional to the fractional amount of the total bandwidth of the switch used by the corresponding packet flow.
