Design and Study of the Active Router Structure

Active network is a new framework where network nodes not only forward packets, but also perform customized computation on the packets flowing through them. It provides a programmable interface to the user where users dynamically inject services into the intermediate nodes. This paper brings forward a structure of active router based on 1P network, analyses the extended definition field of IP datagram at~u the format of the active 1P datagram, studies the module structure, the logic flow chart and the arithmetic of active router, thereby realizes the active networks technology in IP network and extends the service in existent network.
