  1. A Policy-Based Optical VPN Management Architecture

  2. Motivation • Advances and convergence of IP and optical networking: • Intelligent IP-based distributed optical control plane: Generalized Multiprotocol Label Switching (GMPLS) • Provisioning of advanced connectivity services • Successful deployment of IP and MPLS-based Virtual Private Network (VPN) services How to provide VPN services on GMPLS-enabled optical networks? Optical VPN enable multiple customer networks to share a single optical infrastructure

  3. Approach • Optical VPN service configuration management • Policy-Based Management • Web Services management interface Management-based VPN Service Model

  4. Proposed Solution • Policy definition and classification: • Configuration • Admission Control • Routing • Proposed Architecture: • Policy-based OVPN management architecture

  5. Conclusion and Future Work • Prototype implementation and simulations: • Feasibility of the proposed architecture • Our main contribution has been to demonstrate how policy-based management can simplify and automate Optical VPN management • Future work includes: • How to provide Optical VPN services over multiple routing domains? • How VPN resource allocation can benefit from policy-based management?
