Policers receive packets of flows of packet traffic, which are to be communicated to monitored resource. The utilization levels of the monitored resource are induced by these flows of packet traffic. Based on the observed utilization levels (including possibly measured durations in one or more of these utilization levels), a determination is made if, and how to adjust policers for policing their respective flow, with policers being adjusted accordingly. In this manner, adaptive policers (typically located remotely from the monitored resource) are adjusted in response to one or more utilization levels (including possible durations at these utilization levels—i.e., a persistence of the congestion for the resource) of one or more monitored resources, with these identified utilization levels (and possibly durations) used in determining how much to modify a policing rate. |
