Active Network Definition A programmable network is a packet transmission network. It's an open an extensible architecture. The goal is a very quick method for the integration of the new services . It's an extensible network, it's easy change the comportment and dynamically. (following how the clients use it) The actual networks (1/2) For the new services, the cost is high and the deployment is slow. The standardization is necessary Ex : IPV6, Diffserv Re-use the actual services Ex : UDP et TCP A transparent and passive network No interaction between the semantic of data and the service's live. The actual networks (2/2) The network devices are closed Programmable only with the customer interfaces No modifications dynamically Lack of interoperability Between the different customers (Router) Between the routers and the services customers with add value New model for the network Active network To/From To/From/How
