Abstract: A method for routing is disclosed. The method comprises provisioning an endpoint in a network with a reactive path selection policy; monitoring, by the endpoint, current conditions relating to various paths available to said end point for the transmission of traffic; and selectively applying, by the endpoint, at least a portion of the reactive path selection policy based on the current conditions of the available paths.

Abstract: A method for operating a network is provided. The method comprises segmenting the network into a plurality of virtual private networks, wherein each virtual private network runs on an underlying physical network; and wherein each virtual private network represents a particular context; and configuring at least some nodes within the network to send and receive traffic based on context.

Abstract: A method of routing network traffic may include routing traffic from a local network device, through a remote network location, to a third party network resource along a first path. The method may also include determining a first ranking for the first path, and determining a second ranking for a second path from the local network device to the third party network resource along a second path, the second path excluding the remote network location. The method may additionally include, based on the second ranking exceeding the first ranking by a threshold amount, rerouting the traffic along the second path.

Abstract: A method for establishing a communication sessions based on a Network Address Translation (NAT) device is provided. The method comprises configuring the NAT device with policy to control the creation of NAT translation entries to support communications between devices residing behind the NAT device, and devices residing outside the NAT device; wherein said policy allows the NAT device to establish multiple communications sessions, each with a dynamic NAT traversal behavior; and configuring the NAT device to maintain a control plane session with an orchestrator device whereby the NAT device learns parameters required to establish a translation entry for each communications session.

Abstract: A method for creating a secure link between any two endpoints in a network comprises: assigning a unique identifier to each endpoint of a network; for each endpoint in the network, transmitting the unique identifiers associated with each of the remaining endpoints in the network to said endpoint; establishing a secure link between a source endpoint and a destination comprising: transmitting a data-session establishment packet from the source endpoint to the destination endpoint via a symmetric NAT device; wherein the data-session establishment packet comprises the unique identifier associated with the source endpoint; performing a matching operation at the destination endpoint to match the unique identifier associated with the source endpoint with a unique identifier known to the destination endpoint; and upon matching of unique identifiers then creating a forwarding table entry for the destination endpoint based on the source address and source port associated with the source endpoint.

Abstract: A method for routing is disclosed. The method comprises establishing an overlay network, comprising a plurality of network elements and an overlay controller; wherein the overlay controller is in communication with each network element via a secure tunnel established through an underlying transport network; receiving by the overlay controller, information from each service-hosting network element information said information identifying a service hosted at that service-hosting network element, and label associated with the service-hosting network element; identifying by the overlay controller, at least one policy that associates traffic from a site with a service; and causing by said overly controller, the at least one policy to be executed so that traffic from the site identified in the policy is routed using the underlying transport network to the service-hosting network element associated with the said service.
