Abstract
A system and method for dynamically policing network traffic based on egress queue status and a network node incorporating the system or the method. In one embodiment, the system includes: (1) a policing engine configured to receive egress queue status information and (2) a pushback calculator associated with the policing engine and configured to produce a reduction calculation based on the egress queue status information, the policing engine further configured to produce a throttle signal to reduce a traffic policing rate of an ingress queue.
Claims17
A system for dynamically policing network traffic based on egress queue status, comprising:
- a policing engine configured to receive egress queue status information;
- and
- a pushback calculator associated with said policing engine and configured to produce a reduction calculation based on said egress queue status information, said policing engine further configured to produce a throttle signal to reduce a traffic policing rate of an ingress queue wherein said egress queue status information includes a percentage of capacity by which an egress queue is filled.
A method of dynamically policing network traffic based on egress queue status, comprising:
- receiving egress queue status information;
- producing a reduction calculation based on said egress queue status information, wherein said egress queue status information includes a percentage of capacity by which an egress queue is filled;
- and
- producing a throttle signal to reduce a traffic policing rate of an ingress queue,
- wherein said receiving and producing are performed by a processor.
A network node in a network that employs DiffServ-based QoS, comprising:
- a plurality of ingress queues;
- a plurality of egress queues;
- a policing engine configured to receive status information regarding said plurality of egress queues;
- and
- a pushback calculator associated with said policing engine and configured to produce a reduction calculation based on said egress queue status information for at least of said plurality of ingress queues, said policing engine further configured to produce a throttle signal to reduce a traffic policing rate of said at least one of said plurality of ingress queues and wherein said egress queue status information includes a percentage of capacity by which an egress queue is filled.
