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: The present disclosure describes several key features of an agent deployable on a service appliance: agent architecture/design, transport and channel abstractions of the agent, new message definition components, channel switching (e.g., platform independent processing), Channel state machine, platform dependent hooks (e.g., memory, timers), Service key data store, and Secure channel infrastructure. Many of these features alleviate the vendor of the service appliance from having to provide the features. The features and standardization thereof enable the system to be more robust (and increases code quality). Speed of integration is decreased while the risk of integration issues is also decreased. Updates to the agent can be deployed in a controlled and efficient manner. Furthermore, the agent can ensure security between a switch and the agent. The agent deployed and running on vendor appliances provides a unique way to present transport channels that run between the switch, agent, and other service appliance components.

Abstract: A method of creating a connection between a controller and plurality of edge devices may include reading, by a data plane development kit (DPDK) of the controller, a plurality of packets having a common destination port from the plurality of edge devices, and demuxing, by the DPDK, a number of frames of the plurality of packets based on a hash of the plurality of packets, the hash altering the common destination port of the plurality of packets with a corresponding number of sham destination ports. The method may also include, with a TUNTAP interface, injecting the plurality of packets into a network kernel, and with the network kernel, delivering the plurality of packets to a respective one of a plurality of daemon instances.
