In one exemplary aspect, an edge-gateway multipath method includes the step of providing an edge device in a local network communicatively coupled with a cloud-computing service in a cloud-computing network. A set of wide area network (WAN) links connected to the edge device are automatically detected. The WAN links are automatically measured without the need for an external router. The edge device is communicatively coupled with a central configuration point in the cloud-computing network. The method further includes the step of downloading, from the central configuration point, an enterprise-specific configuration data into the edge device. The enterprise-specific configuration data includes the gateway information. The edge device is communicatively coupled with a gateway in the cloud-computing network. The communicatively coupling of the edge device with the gateway includes a multipath (MP) protocol.

In one aspect, a computerized method includes the step of providing process monitor in a Gateway. The method includes the step of, with the process monitor, launching a Gateway Daemon (GWD). The GWD runs a GWD process that implements a Network Address Translation (NAT) process. The NAT process includes receiving a set of data packets from one or more Edge devices and forwarding the set of data packets to a public Internet. The method includes the step of receiving another set of data packets from the public Internet and forwarding the other set of data packets to the one or more Edge devices. The method includes the step of launching a Network Address Translation daemon (NATD). The method includes the step of detecting that the GWD process is interrupted; moving the NAT process to the NATD.

Method and system of resiliency in cloud-delivered SD-WAN

In one aspect, a computerized method useful for connecting to a multipath hub in a cluster includes the step of, with a gateway in a same network as the cluster, receiving, from a branch edge, a request to connect to a logical identifier (ID) of the multipath hub. The gateway recognizes a logical ID representing a cluster. The gateway determines a least-loaded edge in the cluster to be the multipath hub. The gateway returns a connectivity information for the multipath hub. The branch edge configures a tunnel to the multipath hub.

A multi-tenant cloud native system for providing network connections between a plurality of gateway endpoints using tags and secure tunnels. The system includes an end-user device, a cloud control plane, and a cloud provider. The end-user device includes a client endpoint providing a request for establishing a network connection with a service endpoint of the gateway endpoint. Zones and tenants are identified from the request. Tags are assigned to the gateway endpoints in the network based on a tag policy. Connectivity of the tags and tunnels between the gateway endpoint are identified from network traffic of devices corresponding to the gateway endpoints. A database of devices with device addresses is identified to determine routes between the gateway endpoints. A secure tunnel is determined from the plurality of tunnels based on the tags corresponding to the tenant and the network connection is established via the secure tunnel using the routes.

A control plane system for providing data exchange between a plurality of gateway endpoints using a secure tunnel between the gateway endpoints. The system includes an end-user device, a cloud control plane, and a cloud provider. The end-user device includes a client endpoint providing a request for accessing data using a gateway device by sending data packets. The cloud control plane uses a data plane and a control plane for provisioning the request. The control plane is isolated from the data plane. Routing information of network traffic is received, a tenant associated with the request is identified and isolated. A network policy associated with the access to the data is identified based on the network patterns. The network policy specifies routing for access to the data and the secure tunnel. The access to the data is provided from the cloud provider to the client endpoint on the gateway device.

In one aspect, A computerized method of a gateway distributing routes learned through routing protocols (RP) into a Border Gateway Protocol (BGP) includes the step of providing a first gateway that receives a route over a routing protocol. The method includes the step of with the first gateway, redistributing the route to one or more peer routers as a BGP route based on one or more specified criteria. The method includes the step of setting a gateway precedence based on the redistribution of the route to the one or more peer routers as the BGP route. The method includes the step of, based on the gateway precedence, setting a second gateway to automatically redistribute the route with different priorities to influence steering of traffic to a preferred gateway.

In one aspect, a computerized system useful for implementing a virtual private network (VPN) including an edge device that automatically establishes an Internet Protocol Security (IPsec) tunnel alongside an unsecure Multipath Protocol (MP) tunnel with a gateway device in preparation for a transmission of a secure traffic communication. The edge device has a list of local subnets. The edge device sends the list of local subnets to the gateway during an initial MP tunnel establishment handshake message exchange between the edge device and the gateway device. Each subnet includes an indication of whether the subnet is reachable over the VPN. A gateway device that automatically establishes the IPsec tunnel alongside the unsecure MP tunnel with the edge device. An enterprise datacenter server that comprises an orchestrator module that receives a toggle the VPN command and enables the VPN on the orchestrator. The orchestrator informs the edge device the list of subnets is accessible over the VPN causing the edge device to update the gateway device with a new list of subnets of the edge device that accessible over the VPN.
