Current technological advancements impose a strong demand for in future Internet for a capacity to modify dynamically the data plane or control plane; often fast and effectively at runtime in response to emerging conditions. Currently, ad-hoc dynamic tuning of existing functionality is being advocated in different cross- layer optimisations and in the past a number of frameworks have been proposed, mainly in active networking research, for enabling incremental extension of existing functionality. However in both cases the degree of adaptability is rather limited. In this article we advocate a more holistic approach of adapting data or control plane functionality to satisfy different requirements and serve orthogonal adaptation processes. We present the design of a framework able to support functional composition, optimisation and customisation of network services through dynamic selection and on-demand modification of network functions.
