GMPLS-based dynamic OVPN technique in automatically switched optical network (ASON)

Abstract

Optical Virtual Private Network (OVPN) is an increasingly important application of Automatic Switched Optical Network (ASON). To meet the demands of today's different types of network services, dynamic OVPN technique is studied and two new functions are brought forward, which are dynamic connection management, and fast protection/restoration. We realize dynamic OVPN technique in the first ASON testbed in China, based on GMPLS signaling mechanism. The dynamic OVPN technique makes the optical network able to provide customers with reliable and flexible services by more functional and intelligent methods.
