With the emergence of new needs and technologies, the current protocols design and networks architectures seem to reach its evolution and innovation limits. To this end, and under the Post- IP research direction, we propose a new protocol model designed for protocols in the Future Internet. To emphasize and highlight the benefits of our solution, we propose a Service Oriented Architecture (SOA)-based implementation which provides flexibility, and selfadaptability as well as technology transparency. The proposed reference architecture is defined for the Nth stratum concpet of the 4WARD consortium.
