The paper discusses a research program for a clean slate design of a "Future Internet" undertaken by Bell Labs in cooperation with a consortium of major European operators, manufacturers, and academia. The research cooperation explores innovative solutions in architectural design, virtualization, and generic connectivity in order to create a future "network of information." We describe high-level goals and identify technical requirements and the expected business opportunities of this initiative. A basic idea for a new networking concept-the "generic path"-is outlined as an example of how to realize this in the future. © 2009 Alcatel-Lucent.to upcoming services and applications, or which innovative new approaches demand disruptive development. Answering these questions needs broad and in-depth analysis and investigation of novel approaches starting from different angles of consideration, and including a broad spectrum of opinions from current and potential future stakeholders. Obviously, this requires a high degree of cooperation among the players in the industry and operators.Information and communication technologies (ICT) provide the backbone for the "knowledge economy" of the future and account for around half of the productivity growth in modern economies. The importance of innovative ICT for improving the competitiveness of the whole industry was pointed out by the European Commission when they initiated the Seventh Framework Programme (FP7) for funding research in Europe from 2007 to 2013 [4]. The first call for the years 2008 and 2009 identified seven research challenges, one of which comprised the "Network of the Future." In that category, the 4WARD IntroductionWhile the growth of the current Internet in terms of traffic, number of users, and spectrum of applications is still significant, it becomes increasingly evident that today's network architectures are stifling innovation, restricting it mostly to the application level while required structural changes in the underlying networking concepts are not pursued with reasonable effort.The absence of adequate facilities to design, optimize, and interoperate new networks, including both leading edge wireline and wireless technologies, currently forces an "undirected" evolution to a complex architecture that is governed by a multitude of "patches" to the original Internet protocol suite and may therefore only be suboptimal for many future applications. This has often been illustrated by the well-known Internet hourglass model, shown in Figure 1.The decisive question is if, and to what extent, the current Internet approach will be able to adapt in terms of complexity, cost, performance, and suitability project has been awarded an initial grant as an international research cooperative project conducted by a consortium of major European operators, manufacturers, and academia, with Bell Labs in Germany and France as major partners [3]. This paper is based partly on the discussions and first research results obtained within this project.The project aims to evolve...

Abstract. Widespread deployment of Hybrid Fiber Coaxial (HFC) systems created a new residential access platform upgrading traditional cable TV networks. which were limited to distributed services. This evolution is driven by demand for faster Internet access from customers frustrated by slow telephone line and ISDN modem speeds. As residential traffic with voice and video-intensive content proliferates. the cumnt generation of cable modems, which are oriented towards best-effort traffic, will need to be enhanced with new capabilities to handle the increased bandwidth and quality requirements. To integrate telecom services presenting diverse quality requirements over the same HFC access infrastructure necessitates a degree of isolation of traffic classes. The difficulty of handling finer aggregations because of the limited MAC reservation resources and the cost limitation of residential access make the scalability of the differentiated services architecture as relevant in the HFC access network as in any traffic multiplexer. An implementation integrating IP and ATM and aligning the system to the DiffServ philosophy is presented in this paper. It constitutes an affordable system solution for residential customers enabling the support of QoS-demanding services.
