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.

Scalable creation of connections

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.

Horizontal scaling for a software defined wide area network (SD-WAN)

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.

Systems and methods for detecting domain changes in an SD-WAN environment

Aspects of the present disclosure relate to flexible and automatic provisioning of virtual instances in a virtual network using single-root input/output virtualization. A device pool is defined that is associated with a virtual entity, such as a virtual switch, in a data center. The device pool identifies available physical hardware devices of one or more host machines, such physical network interfaces connected to the virtual switch, and the device pool is associated with the virtual entity. When a virtual computing instance is connected to the virtual entity, such as when initialized or after migrating between hosts, one or more physical hardware devices are automatically assigned from the device pool to the virtual computing instance based on the association of the device pool to the connected virtual entity. Thus, VMs can be flexibly and automatically provisioned with SR-IOV physical hardware when migrating between hosts using SR-IOV.
