碩士 === 國立中央大學 === 資訊工程研究所 === 93 === With the rise of internet, the demands of Virtual Private Network (VPN) services are increased day by day. Due to the expansion of enterprises, information transferring inside the enterprise or between enterprises is not limited in the managed and high security network but through the shared infrastructure. VPN services play the important role under this situation, in order to securely transfer confidential data to the destination. Nowadays, the network populations using VPN services can be divided into three levels: service provider administrator with service provider backbone; local device manager directly connected with service provider and end user using network services. Among network populations described above, service provider administrators provide the interconnectivity among separated local devices, while local device manager provide network connectivity for end users. This thesis proposes two-level VPN service provisioning systems which contain two types of VPN provisioning systems. They are Provider Edge Manager (PER) deployed in service provider backbone and Customer Edge Manager (CAR) deployed in local device. PER deals with provisioning MultiProtocol Label Switching (MPLS) VPN service to local device manager and CAR takes charge of deploying Customer Premises Edge-based (CPE-based) for end users. Local device managers can deploy CPE-based VPN services on MPLS VPN services provided by service provider administrators through information and VPN status exchange among PER and CAR, and reach the goals of providing VPN services for end users.
