A Policy-Based Optical VPN Management Architecture

This paper explores the development of a policy-based management architecture for Optical VPNs, driven by the convergence of IP and optical networking technologies. It highlights the advancements in intelligent IP-based distributed optical control planes, including GMPLS, enabling the provisioning of advanced connectivity services and successful deployment of MPLS-based VPN services. A proposed solution for managing Optical VPN services through policy definition, configuration, and routing is discussed, demonstrating how automated management can simplify operations. Future work will address Optical VPN services across multiple routing domains.

  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?
