Systems and methods for flow-based traffic shaping

摘要

A system controls transmission of packet flows in a network device on a per-flow basis. The system includes multiple token buckets corresponding to the output ports of the network device, multiple bucket counters associated with the token buckets, and control logic. The token buckets store one or more tokens. Each of the tokens corresponds to a portion of one or more received packet flows to be transmitted by the network device. The bucket counters have one or more programmable counting properties and generate token increment signals for storing tokens in corresponding ones of the token buckets. The control logic monitors the packet flows being sent through the network device and controls the programmable counting properties of the bucket counters based on the monitored packet flows.
