This document presents an initial proposal for the architecture of the Future Internet. The architecture has been developed by the Trilogy collaborative research project, whose focus is the development of the current Internet, and in particular its network and transport layers. The key challenges identified include scaling and flexibility in the global routing system, and resilience and resource management to support the needs and demands of emerging applications. As well as the strictly technical aspect, the new architecture aims to incorporate the necessary flexibility to adapt to changing economic and social stresses, the so-called “design for tussle”. While the architecture and Design Principles are presented here as an evolutionary step from the original Internet concepts, the implications for future network evolution are wide ranging. The architecture is currently in an initial form, and this document also highlights the open research issues and necessary validation activities, as well as the relationship to other ongoing Future Internet research. Target audience The primary target audience for this document is the networking research and development community, particularly those with an interest in the Future Internet. The material should be accessibl
