Abstract
A method is provided that includes setting a first oversubscription factor of a control plane for an interface, measuring forwarding plane utilization on the interface, and calculating a second oversubscription factor of the control plane for the interface using the measured forwarding plane utilization as compared with a target forwarding plane utilization on the interface. The method also includes determining whether to update the first oversubscription factor based upon the calculated second oversubscription factor.
Claims17
A method comprising:
- sampling forwarding plane utilization associated with a control plane of an interface of a router;
- changing an advertised bandwidth of the control plane based upon updating of an oversubscription factor for the interface to a new oversubscription factor;
- and
- determining a decrease interval and an increase interval to regulate frequency of the updating of the oversubscription factor.
A method of comprising:
- sampling forwarding plane utilization associated with a control plane of an interface of a router;
- and
- changing an advertised bandwidth of the control plane based upon updating of an oversubscription factor for the interface to a new oversubscription factor, wherein the oversubscription factor is a first one of two oversubscription factors, the method further comprising:
- determining a second one of the oversubscription factors of the control plane using the sampled forwarding plane utilization.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
- sample forwarding plane utilization associated with a control plane of an interface of a router
- change an advertised bandwidth of the control plane based upon updating of an oversubscription factor for the interface to a new oversubscription factor, and
- determine a decrease interval and an increase interval to regulate frequency of the updating of the oversubscription factor.
An apparatus of comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
- sample forwarding plane utilization associated with a control plane of an interface of a router, and
- change an advertised bandwidth of the control plane based upon updating of an oversubscription factor for the interface to a new oversubscription factor,
- wherein the oversubscription factor is a first one of two oversubscription factors, and the apparatus is further caused to:
- determine a second one of the oversubscription factors of the control plane using the sampled forwarding plane utilization.
A system comprising:
- a plurality of logical routers;
- and
- a forwarding plane coupled to the logical routers via a messaging bus,
- wherein forwarding plane utilization associated with a control plane of one or more of the logical routers is sampled, and an advertised bandwidth of the control plane is changed based upon updating of an oversubscription factor for the interface to a new oversubscription factor, and
- wherein the oversubscription factor is a first one of two oversubscription factors, and a second one of the oversubscription factors of the control plane is determined using the sampled forwarding plane utilization.
