Abstract: Implementing VPN on the active network makes full use of the active network distinguished feature: matching network behavior to the user application. By equipping the capsule with transformer program, optimizing key exchanged algorithm, designing QoS routing algorithm and mobile bandage allocation algorithms. the VPN on active network which provides flexible and scalable quality of service can ba well implemented and it is more secure and efficient.
