Some embodiments of the invention provide a method of facilitating routing through a software-defined wide area network (SD-WAN) defined for an entity. A first edge forwarding node located at a first multi-machine site of the entity, the first multi-machine site at a first physical location and including a first set of machines, serves as an edge forwarding node for the first set of machines by forwarding packets between the first set of machines and other machines associated with the entity via other forwarding nodes in the SD-WAN. The first edge forwarding node receives configuration data specifying for the first edge forwarding node to serve as a hub forwarding node for forwarding a set of packets from a second set of machines associated with the entity and operating at a second multi-machine site at a second physical location to a third set of machines associated with the entity and operating at a third multi-machine site at a third physical location. The first edge forwarding node serves as a hub forwarding node to forward the set of packets from the second set of machines to the third set of machines.

Broadband communications devices and methods operate with at least two separate communication paths between the devices and the network, such as the Internet. The broadband devices and methods receive data concurrently over the communication paths or separately. The bandwidth is increased when the separate communication paths are combined. The broadband devices employ packetized data with Voice over Internet Protocol (VoIP) technologies combined with RF communications technologies.

A first network device receives an association relationship sent by a second network device, where the association relationship includes an association relationship between a first path and a second path. The first network device generates first routing information between the first network device and a target network device based on the association relationship, where the first routing information is used by the first network device to send a packet to the target network device through the first path, and when a cross-slice condition is met, the first routing information is used by the first network device to send a packet to the target network device through the second path.

The present application relates to traffic routing for overlay paths in a public cloud network. A path orchestrator receives a configuration of a set of overlay paths for a wide area network virtualization from a client, each overlay path including virtual routing nodes associated with respective geographic regions and at least one policy for a link between the virtual routing nodes. The path orchestrator is configured to instantiate a plurality of virtual routers on computing resources of the public cloud network located within the respective geographic regions based on the configuration, each virtual router configured to route traffic according to the policy for each link associated with the virtual routing node corresponding to the virtual router. The path orchestrator is configured to scale the plurality of virtual routers based on traffic for the client on the set of overlay paths.

Rapid channel failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet channel standards. Thus, resilient wireless packet communications is provided using a physical layer link aggregation protocol with a hardware-assisted rapid channel failure detection algorithm and load balancing, preferably in combination. This functionality may be implemented in a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, these features may be provided in combination with their existing protocols.
