A programmable network Is a packet transmission network It's an open an
extensible arcnitecture
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)
Trang 3

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
+ No interaction between the semantic of
data and the services live.

4 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
