Abstract
A system and method for input thresholding packets in a network switch. A network switch may include multiple input ports, multiple output ports, and a shared random access memory coupled to the input ports and output ports by data transport logic. Packets entering the network switch may be assigned to one of a plurality of threshold groups and to one of a plurality of flows within the threshold group. In one embodiment, each threshold group may be divided into a plurality of levels of operation. As resources are allocated or freed by the threshold group, the threshold group may dynamically move up or down in the levels of operation. Within each level, one or more different values may be used as level boundaries and resource limits for flows within the threshold group. In one embodiment, programmable registers may be used to store these values.
