System, device, and method for providing distributed quality-of-service control and policy enforcement

A non-transitory storage medium having stored thereon instructions that, when executed by a processor, cause the processor to perform a method comprising:

• constructing a tree hierarchy representation that corresponds to distributed enforcement of a Quality-of-Service (QoS) policy on incoming packets that are intended for transmission towards a destination, said tree hierarchy representation utilized by at least two separate Processing Units (PUs) that separately process different packets that are intended for transmission towards said destination;
• generating an association between (I) a first set of instances of parent-child Policy Objects of QoS enforcement, and (II) a first PU;
• and generating a separate association between (i) a second set of instances of said parent-child Policy Objects of QoS enforcement, and (ii) a second PU;
• performing a cross-PU Instances Synchronization process, which automatically determines that the first PU caused modification of said first set of instances of said parent-child Policy Objects that are utilized by the first PU, and which dynamically causes a corresponding modification to said second set of instances of said parent-child Policy Objects that are utilized by the second PU;
• wherein the Cross-PU Instances Synchronization process is to dynamically synchronize, in real-time or in near-real-time, multiple instances of a Parent policy object of QoS enforcement that are associated separately with two or more PUs;
• wherein the Cross-PU Instances Synchronization process is to dynamically synchronize, in real-time or in near-real-time, multiple instances of a Child policy object of QoS enforcement that are associated separately with two or more PUs.

A system comprising:

• one or more hardware processor to execute code,
• operably associated with one or more memory units to store code,
• wherein the one or more hardware processors are configured:
• to construct a tree hierarchy representation that corresponds to distributed enforcement of a Quality-of-Service (QoS) policy on incoming packets that are intended for transmission towards a destination, said tree hierarchy representation utilized by at least two separate Processing Units (PUs) that separately process different packets that are intended for transmission towards said destination;
• to generate an association between (I) a first set of instances of parent-child Policy Objects of QoS enforcement, and (II) a first PU;
• and to generate a separate association between (i) a second set of instances of said parent-child Policy Objects of QoS enforcement, and (ii) a second PU;
• to perform a cross-PU Instances Synchronization process, which automatically determines that the first PU caused modification of said first set of instances of said parent-child Policy Objects that are utilized by the first PU, and which dynamically causes a corresponding modification to said second set of instances of said parent-child Policy Objects that are utilized by the second PU;
• wherein the Cross-PU Instances Synchronization process is to dynamically synchronize, in real-time or in near-real-time, multiple instances of a Parent policy object of QoS enforcement that are associated separately with two or more PUs;
• wherein the Cross-PU Instances Synchronization process is to dynamically synchronize, in real-time or in near-real-time, multiple instances of a Child policy object of QoS enforcement that are associated separately with two or more PUs.
