Abstract
The ability to rapidly create, deploy, and manage new network services in response to user demands presents a significant challenge to the research community and is a key factor driving the development of programmable networks. Existing network architectures such as the Internet, mobile, telephone, and asynchronous transfer mode (ATM) exhibit two key limitations that prevent us from meeting this challenge:
" Lack of intrinsic architectural flexibility in adapting to new user needs and requirements
" Lack of automation of the process of realization and deployment of new and distinct network architectures
In what follows we make a number of observations about the limitations encountered when designing and deploying network architectures. First, current network architectures are deployed on top of a multitude of networking technologies such as land-based, wireless, mobile, and satellite for a bewildering array of voice, video, and data applications. Since these architectures offer a very limited capability to match the many environments and applications, the deployment of these architectures has predictably met with various degrees of success.
