Abstract
A request is received for secure network traffic from a device having a private network address at a source node. The private network address of a requested destination device is obtained at a destination node from a route server based on signaling information associated with the request. The public network address of the destination node associated with the private network address is obtained. In response to the request, a virtual circuit is created between the source node and the destination node based on the public network address of the destination node. Network traffic is encrypted for transport at least from the source node to the destination node through the virtual circuit. Creating the virtual circuit dynamically in response to the request functions like a fully meshed network but requires less provisioning and maintenance. The process is readily scalable, as with a hub and spoke network but with less delay.
