Distriburted QoS policing system and method

摘要

A method for policing traffic on a computer communications network having a multitude of nodes interconnected by various communications media. An individual policer is established at each node for monitoring and/or policing the traffic incoming to that node. Traffic policy parameters are established for traffic-classes and the policy is implemented at each individual policer. Thresholds may be established and when the thresholds are met or exceeded the individual policer will export the traffic conditions at the respective node. The other individual policers or a master policer will receive the exported information. -The individual policers police the traffic incoming to its associated node depending on the traffic condition information received from all the nodes. Several classes may be handled by each individual policer. Leaky bucket algorithms may be used in some instances.
