Abstract

System, device, and method for providing distributed quality-of-service control and policy enforcement. A tree hierarchy representation is constructed for distributed enforcement of a Quality-of-Service (QoS) policy on incoming packets that are intended for transmission towards a destination, by at least two separate Processing Units (PUs) that separately process different packets that are intended for transmission towards that destination. A cross-PU Instances Synchronization Unit automatically determines that a first PU caused modification of a first set of instances of parent-child Policy Objects that are utilized by the first PU, and dynamically causes a corresponding modification to a second set of instances of parent-child Policy Objects that are utilized by a second PU. The QoS policy is enforced, on a packet-by-packet basis, by different member entities of the tree hierarchy representation, to achieve the overall QoS policy.
