Abstract: Active network is the basis for a range of new and innovative applications that make use of computational resources inside network routers. This paper concentrates on the architecture of active VPN multicast, analyzes the architecture of VPN multicast on traditional network and its insufficiency, then a new way to realize VPN multicast using the active network is presented.The main advantages include better session key management, improved security, greater availability, anti denial of service attacks and simple authentication.
