This paper describes a way of creating the OVPN through the management plane and manages the OVPN with a centralized method in Automatic Switch Optical Network (ASON). Through the extension of resource management, signal mechanism and connection control, the architecture of OVPN creation and OVPN maintenance with a centralized method is efficiently realized, and the requirements of multi- granularity, bandwidth modification and link monitory are realized. Moreover, Service Lever Agreement (SLA) can be included in OVPN through Switched Connection (SC) and Soft permanent connection (SPC). If further study is carried through on this scenario, the optical multicast will be realized under both the mechanisms of management plane and control plane. At last, the applications area, account model and development prospect of OVPN are discussed.
