Scheduling traffic over aggregated bundles of links

A router comprising:

• a control plane that configures a plurality of primary logical interfaces within a forwarding plane of the router for a plurality of subscribers of one or more services provided by a service provider network over an aggregated bundle of two or more links such that each of the plurality of primary logical interfaces is associated with a respective first primary link of the aggregated bundle of two or more links, wherein each of the plurality of primary logical interfaces is configured to be associated with a primary scheduling module that schedules traffic associated with a subscriber of the plurality of subscribers for delivery downstream to the subscriber via the respective first primary link of the aggregated bundle of two or more links,
• wherein the control plane further, prior to detecting a failure associated with the primary scheduling module, configures a plurality of backup logical interfaces within the forwarding plane of the router and for the plurality of subscribers such that the backup logical interface is associated with a respective second backup link of the aggregated bundle of two or more links and provides redundancy of connection over the aggregate bundle in the event of a failure associated with the corresponding primary scheduling module and permit the traffic associated with the subscriber to be forwarded despite the failure associated with the corresponding primary scheduling module,
• wherein each of the plurality of backup logical interfaces is configured to be associated with a backup scheduling module that schedules, in response to detecting the failure associated with the corresponding primary scheduling module, the traffic associated with the subscriber for delivery downstream to the subscriber via the respective second backup link of the aggregated bundle of two or more links, and
• wherein the control plane configures the plurality of primary logical interfaces and the plurality of backup logical interfaces for each of the plurality of subscribers to be evenly distributed over the aggregated bundle of two or more links.

A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors of a a control plane of a router to:

• configure a plurality of primary logical interfaces within a forwarding plane of the router and for a plurality of subscribers of one or more services provided by a service provider network over an aggregated bundle of two or more links such that each of the plurality of primary logical interfaces is associated with a respective first primary link of the aggregated bundle of two or more links,
• wherein each of the plurality of primary logical interfaces is configured to be associated with a primary scheduling module that schedules traffic associated with a subscriber of the plurality of subscribers for delivery downstream to the subscriber via the respective first primary link of the aggregated bundle of two or more links;
• and
• prior to detecting a failure associated with the primary scheduling module, configure a plurality of backup logical interfaces within the forwarding plane of the router and for the plurality of subscribers such that the backup logical interface is associated with a respective second backup link of the aggregated bundle of two or more links,
• wherein each of the backup logical interfaces is configured to be associated with a backup scheduling module that schedules, in response to detecting the failure associated with the corresponding primary scheduling module, the traffic associated with the subscriber for delivery downstream to the subscriber via the respective second backup link of the aggregated bundle of two or more links and provides redundancy of connection over the aggregate bundle in the event of a failure associated with the corresponding primary scheduling module and permit the traffic associated with the subscriber to be forwarded despite the failure associated with the corresponding primary scheduling module, and
• wherein the plurality of primary logical interfaces and the plurality of backup logical interfaces are configured for each of the plurality of subscribers to be evenly distributed over the aggregated bundle of two or more links.

A method comprising:

• configuring, with a control plane of a router, a primary logical interface of a plurality of primary logical interfaces within a forwarding plane of the router and to schedule traffic for delivery over an aggregated bundle of two or more links such that the primary logical interface is associated with a first primary link of the aggregated bundle of two or more links,
• wherein the primary logical interface is configured to be associated with a primary scheduling module that schedules the traffic for delivery via the first primary link of the aggregated bundle of two or more links;
• and
• prior to detecting a failure associated with the primary scheduling module, configuring, with the control plane, a backup logical interface of a plurality of backup logical interfaces within the forwarding plane of the router and such that the backup logical interface is associated with a second backup link of the aggregated bundle of two or more links and provides redundancy of connection over the aggregate bundle in the event of a failure associated with the corresponding primary scheduling module and permit the traffic to be forwarded despite the failure associated with the corresponding primary scheduling module,
• wherein the backup logical interface is configured to be associated with a backup scheduling module that schedules, in response to detecting the failure associated with the primary scheduling module, the traffic for delivery downstream via the second backup link of the aggregated bundle of two or more links, and
• wherein the plurality of primary logical interfaces and the plurality of backup logical interfaces are configured to be evenly distributed over the aggregated bundle of two or more links.
