Abstract: 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.

Abstract: 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.

Abstract: A computerized method useful for implementing a Multi-Source Inbound QoS (Quality of Service) process in a computer network includes the step of calculating a current usage rate of a provider entity. The provider entity is classified by a network traffic priority; implementing a fair sharing policy among a set of provider entities. The method includes the step of adjusting any excess bandwidth among a set of provider entities. The method includes the step of implementing link sharing at a provider-entity level.

Abstract: In one embodiment, a method for the prioritized transmission of messages includes monitoring a network link of a mobile device to determine performance characteristics of the network link, establishing a network association between the mobile device and a routing network node, receiving a connection request from an application that is directed to a connection between the mobile device and a destination server, determining a relative priority of the connection, mapping the connection to a stream of the network association that is associated with the relative priority of the connection and identifies the destination server, and transmitting messages for the stream to the routing network node interlaced with messages of other streams of the network association based on the performance characteristics of the network link and the relative priority associated with the stream in comparison to relative priorities associated with the other streams of the network association.

Abstract: 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.

Abstract: 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.

Abstract: In one aspect, a computerized system useful for implementing a cloud-based multipath routing protocol to an Internet endpoint includes an edge device that provides an entry point into an entity's core network. The entity's core network includes a set of resources to be reliably accessed. The computerized system includes a cloud-edge device instantiated in a public-cloud computing platform. The cloud-edge device joins a same virtual routing and forwarding table as the edge device. The cloud-edge device receives a set of sources and destinations of network traffic that are permitted to access the edge device and the set of resources.

Abstract: In one embodiment, a method comprises obtaining, by a client device via a wireless data link with a wireless access point, information from a network device within a data network reachable via the wireless access point, the information describing network conditions associated with a service provided to the client device via the data network; and the client device optimizing a transmission control protocol (TCP) communication, via the wireless data link, for optimization of the service provided by the client device.

Abstract: In one aspect, a computerized method of an application routing service includes the step of using a deep-packet inspection (DPI) technique on a first network flow to identify an application. The method includes the step of storing an Internet-protocol (IP) address and a port number used by the application and an identity of the application in a database. The method includes the step of detecting a second network flow. The method includes the step of identifying the IP address and the port number of the application in the second network flow. The method includes the step of looking up the IP address and the port number in the database. The method includes the step of identifying the application based on the IP address and the port number.
