Abstract: In one implementation, a policy server establishes a smart virtual private network between two client devices. The smart virtual private network includes a secure communication session using a security level or security algorithm that is variable and defined as a function of the two client devices. A first client device may generate a registration request including a first security configuration including the security level. Based on the registration request, the policy server generates a routing message that defines routing for communication from the first client device to a second client device. The routing message may update a routing table to associate the policy server with the second client device.

Abstract: In one implementation, a hub and spoke network is made up of hub network devices and spoke network devices. A security protocol channel is established between the hub and at least a first spoke. The hub receives a resolution request from the first spoke via the security protocol channel. The resolution request includes data indicative of a second endpoint. The hub queries a next hop client database for a WAN address of the second endpoint. The first endpoint and the second endpoint are geographically separated nodes of the same enterprise network. The hub sends a resolution reply to the first endpoint including the WAN address for the second endpoint. The hub also sends a message to the second endpoint including a WAN address of the first endpoint and a summary of the data packet received at the first endpoint.
