A Policy-Based Optical VPN Management Architecture

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?
