Reliability and security concerns have increased demand for Virtual Private Networks (VPNs). Ideally, a VPN service should offer autonomous overlay networks with guaranteed bandwidth allocations over a shared network. Network providers seek an automated VPN creation and management process, while users of a VPN would greatly benefit from secure control over the handling of their traffic. Currently, network infrastructure does not support such partitioning services and, due to its static nature, it cannot be adapted to meet such new demands. Active and Programmable Network research has developed a number of adaptable architectures. However, its current focus is on theoretical service deployment rather than on applicability to large and shared networking environments. This paper presents the application of a new programmable architecture to enable on-demand VPN construction, bandwidth management, and secure autonomous VPN control onto shared commercial infrastructure. © IFIP International Federation for Information Processing 2007.
