Ring-Based Virtual Private Network Supporting a Large Number of VPNs


In this paper, we propose a simple but effective VPN mechanism called RING-VPN (ring-based virtual private network) that realizes a high scalability in terms of the number of VPNs. The key idea of our RING-VPN is to logically connect nodes in a ring topology for minimizing the number of IPsec tunnels. In our RING-VPN, each VPN node operates autonomously… (More)
