Abstract

Methods for controlling multipriority data flow in a communications systems having a switch fabric and one or more port cards. Each port card has, or is coupled to, a buffer. The buffer is adapted for coupling to, or is integrated into, the switch fabric.
Multipriority data refers to a plurality of data types, wherein each data type is assigned a priority ranking relative to other data types. A first method monitors the occupancy of a buffer. If the occupancy exceeds a second threshold, transmission of a group of second-priority bit streams is disabled until the occupancy drops below a first threshold. If the occupancy exceeds a fourth threshold, transmission of a group of first-priority bit streams is disabled until the occupancy drops below a third threshold. A second method differs from the first method in that control is applied to, and removed from, all bit streams of a given priority level, not just a group of bit streams at this priority level, if the occupancy crosses the previously-described thresholds. A third method is a combination of the first and second methods. To start, the first method is performed.
Once the occupancy exceeds a fifth threshold greater than the fourth threshold, performance of the first method ceases and performance of the second method commences.
