Connecting enclaves across the global information grid utilizing layer-3 virtual private networking protocols

This paper presents a modification to the routing architecture within the global information grid (GIG). Primarily, the goal is to simplify the deployment and reachability of sub-networks deployed behind security gateways. We propose the application of commercially supported layer-3 virtual private networking (L3-VPN) protocols to inter-connect collaborating enclaves. Such an approach alleviates many issues introduced by hiding these enclaves' IP addresses. The application of L3-VPN to the problem allows for the re-use of commercial-off-the-shelf (COTS) products, protocols, and tools to reduce the overall cost of deploying and managing the GIG
