  • Patent number: 11870678
    Abstract: A controller includes a transceiver to establish a first session with a route reflector and monitor advertisements received by the route reflector from nodes in a network via second sessions established between the nodes and the route reflector. The controller also includes a processor to generate forwarding instructions for the nodes based on the advertisements. The forwarding instructions indicate one or more routes from a root node to one or more leaf nodes of a service. The transceiver provides the forwarding instructions to the root node. In some cases, the first session is established according to the border gateway protocol (BGP) and the one or more second sessions are established according to the BGP. The controller determines that the one or more leaf nodes are registered for one or more virtual private network (VPN) services based on the advertisements.

  • Patent number: 11799768
    Abstract: An event routing service may be used to implement lightweight reactive workflows through internal event generation and matching. The service may receive, from a client, specification of event routing rules as well as internal event rules. The internal event rules specified by the client are for matching internal events generated by the service and performing actions in response to the matching of the internal events. For example, when the event routing service determines that one of the incoming events has been successfully delivered to a target service, then the event routing service generates an internal event indicating the successful delivery. The event routing service determines that the internal event matches one of the internal event rules specified by the client. In response, the service performs an action specified by the internal event rule (e.g., send the incoming event to another target or generate a message).
