Abstract: In one embodiment, a method includes generating, by a first controller of a network, an overlay domain digest using a first domain digest associated with the first controller of the network and a second domain digest associated with a second controller of the network. The method also includes communicating, by the first controller, the overlay domain digest to an edge device of the network, updating, by the first controller, the overlay domain digest to generate an updated overlay domain digest, and communicating, by the first controller, the updated overlay domain digest to the edge device of the network. The method further includes detecting, by the edge device, a difference between the overlay domain digest and the updated overlay domain digest and re-establishing, by the edge device, a connection with an orchestrator of the network to determine a control plane domain change within the network.

Abstract: Techniques are described for routing traffic through an interconnect cloud gateway based on cloud traffic routing indicators. The interconnect cloud gateway can advertise the cloud traffic routing indicators, which can include cloud indicators and transport gateway indicators. The cloud indicators can include cloud tags utilized to route cloud traffic. The transport gateway indicators can include transport gateway flags utilized to identify private networks utilized to route the cloud traffic. The cloud traffic can routed during normal private network operation through private networks, which can be dynamically replaced by public networks due to occurrences of failures preventing the data traffic from being routed through the private networks and to cloud networks.

Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for managing networks. According to at least one example, a method is provided for connecting to a network controller across different regions. The method includes identifying a first connection with a network orchestrator during establishment of a second connection with the network orchestrator from a network controller; establishing a sibling session that links the second connection and the first connection at a control plane; inserting a sibling data message that identifies the sibling session into control messages sent; receiving a message from the network orchestrator over the second connection, the message including an address of the network controller associated with the second connection; and transmitting the second address of the network controller over the first connection to the network orchestrator.

Abstract: Embodiments of the present disclosure enable monitoring network traffic on multiple Virtual Device Context (VDC) elements of a switch using a single NAM module. To that end, if a monitored network element supports contexts (i.e. VDC elements), a NAM module could be configured to seamlessly drive the move of the data port interfaces (at the managed device) from one context to the other. After the move of the data ports that support SPAN destination traffic flow to the target VDC is complete, these SPAN destination ports may be configured to be able to receive SPAN data traffic.

Abstract: A method, service appliance, and non-transitory media for establishing connections to virtual device contexts (VDCs) whereby a communication channel for each of the VDCs is identified based on connection data corresponding to each of the VDCs. A service appliance receives, from each of one or more VDCs located on a switch, a message containing connection data that identifies at least one communication channel between the service appliance and a corresponding one of the one or more VDCs from which the message was received. The connection data is stored in a memory accessible to the service appliance. The service appliance identifies a communication channel for each of a plurality of VDCs based on the connection data and an identifier corresponding to each of the plurality of VDCs. The service appliance establishes a connection to each of the plurality of VDCs using the communication channel for each of the plurality of VDCs.
