Abstract
A router configured to implement Border Gateway Protocol (BGP) includes circuitry configured to receive BGP updates from one or more BGP peers connected to the router, detect a trigger related to BGP updates where the trigger is indicative of a need to apply backpressure by the one or more BGP peers, and send a backpressure notification message to the one or more BGP peers based on the trigger, such that the one or more BGP peers apply the backpressure. The circuitry can be further configured to monitor one or more criteria associated with operation of the router, for the trigger.
Claims20
A router configured to implement Border Gateway Protocol (BGP), the router comprising circuitry configured to:
- receive BGP updates from one or more BGP peers connected to the router,
- detect a trigger related to BGP updates where the trigger is indicative of a need to apply backpressure by the one or more BGP peers, wherein the trigger is based at least on a fill rate of a Routing Information Base (RIB) based on the received BGP updates, and
- send a backpressure notification message to the one or more BGP peers based on the trigger, such that the one or more BGP peers apply the backpressure.
A method implemented in a router configured to implement Border Gateway Protocol (BGP), the method comprising steps of:
- receiving BGP updates from one or more BGP peers connected to the router;
- detecting a trigger related to BGP updates where the trigger is indicative of a need to apply backpressure by the one or more BGP peers, wherein the trigger is based at least on a fill rate of a Routing Information Base (RIB) based on the received BGP updates;
- and
- sending a backpressure notification message to the one or more BGP peers based on the trigger, such that the one or more BGP peers apply the backpressure.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors in a router configured to implement Border Gateway Protocol (BGP), cause the one or more processors to perform steps of:
- receiving BGP updates from one or more BGP peers connected to the router;
- detecting a trigger related to BGP updates where the trigger is indicative of a need to apply backpressure by the one or more BGP peers, wherein the trigger is based at least on a fill rate of a Routing Information Base (RIB) based on the received BGP updates;
- and
- sending a backpressure notification message to the one or more BGP peers based on the trigger, such that the one or more BGP peers apply the backpressure.
