ADAPTIVE BUFFERING IN A DISTRIBUTED SYSTEM WITH LATENCY / ADAPTIVE TAIL DROP

Abstract:

A network device includes a switching system for directing packets between ingress ports and egress ports of the network device. The network device also includes a switching system manager that makes an identification of a state change of a virtual output queue of the switching system; and performs an action set, based on the state change, to modify a latency of the virtual output queue to meet a predetermined latency in response to the identification.
