- 3 - DPNM What is Future Internet?  Need to rethink the fundamental assumptions and design decisions underlying its current architecture  Two principal ways in which to evolve or change a system –Evolutionary approach (Incremental): a system is moved from one state to another with incremental patches –Revolutionary approach (Clean-slate): the system is redesigned from scratch to offer improved abstractions and/or performance, while providing similar functionality based on new core principles  Future Internet? –Clean Slate design of the Internet’s architecture to satisfy the growing demands –Management issues of Future Internet also need to be considered from the stage of design  Research Goal for Future Internet –Performing research for Future Internet and designing new network architectures –Building an experimental facility

- 8 - DPNM 4WARD’s Research Goal  Overcomes current Internet architectural impasse through a set of radical architectural approaches built on mobile and wireless background  Improve ability to design interoperable and complementary families of network architecture  Enable the co-existence of multiple networks on common platforms  Enhance the utility of networks by making them self- managing  Increase robustness and efficiency of networks by leveraging diversity  Improve application support by a new information-centric paradigm

- 9 - DPNM 4WARD’s Strategic Objective  By creating a family of dependable and interoperable networks providing direct and ubiquitous access to information –Increase the competitiveness of the European networking industry –Improve the quality of life for European citizens  Goal –Make the development of networks and networked applications faster and easier, leading to both more advanced and more affordable communication services

DPNM Key Issues  Interoperability –A mew approach to a multitude of networks –Create a framework for many networks to bloom as part of a family of interoperable networks that can coexist and complement each other  Self-Management –Have a ‘default-on’ management entity, which is an inseparable part of the network itself –Capable of adjusting itself to difference network sizes, configurations, and external conditions  Active Network Path –Consider a path as an active part of the network that controls itself and provides customized transport services  Information-Centric –Build a network as a network of information and services where services and information are mobile and distributed

DPNM Technical Approach (1)  Combine –Innovations needed to improve the operation of any single network architecture –Multiple different and specialized network architecture  Work –On innovations overcoming the shortcomings of current communication networks (Internet) –In a framework that allows the coexistence, interoperability, and complementarity of several network architecture –In an integrated fashion, avoiding pitfalls like the current Internet’s ‘patch on a patch’ approach

DPNM Technical Approach (2)  Structured into 6 work packages –3 packages: consider innovations for a single network architecture –1 package: study the use of virtualization to allow multiple networking architectures to coexist on the same infrastructure –1 package: Look at the design and development of interoperable architectures –1 package: Ensure that all envisaged developments take proper account of essential non-technical issues

DPNM Work Phases

DPNM Projects  6 work packages

DPNM Work Packages

DPNM WP1: BIRD  Business Innovation, Regulation and Dissemination  To understand and assess both how new technology may foster new usages and business models as well as how new usages and societal trends may require new or enhanced technologies  To investigate implications of policy and governance on networking technologies (including regulation) and vice versa  Dissemination and External Collaboration
