(following how the clients use it) The actual networks (1/2) n  n  For the new services, the cost is high and the deployment is slow. The standardization is necessary n Ex : IPV6, Diffserv n Re-use the actual services n Ex : UDP et TCP n  n A transparent and passive network No interaction between the semantic of data and the service's live. The actual networks (2/2) n n  The network devices are closed n Programmable only with the customer interfaces n No modifications dynamically Lack of interoperability n Between the different customers (Router) n Between the routers and the services customers with add value New model for the network Active network To/From To/From/How
