© 2014 The SmartenIT Consortium 2 Commercial in Confidence SmartenIT Take-off  Internet with the move to support clouds and their as well as many different overlay applications  Coherent and integrated control in underlying heterogeneous networks  Tighter integration of network management and overlay service functionality  SmartenIT  Socially-aware Management of New Overlay Application Traffic combined with Energy Efficiency in the Internet and Panel Relation such as by SDN/NFV to improve QoE, Cost, and Energy Efficiency... a piece of solution to the puzzled zoo of today‘s control and service as well as network management activities.

© 2014 The SmartenIT Consortium 3 Commercial in Confidence SmartenIT Steps and Targets  Incentive-compatible mechanisms in network management for content providers, overlay providers (such as clouds), network providers, and end-users  QoE- and social awareness by traffic characterization based on network-related metrics and social patterns  Energy efficiency with respect to both end-user devices and underlying networking infrastructure  Leading to  Improved network and service management in all layers, on an inter-domain basis  Promising approach to offer a business potential in operational perspectives for all players involved

© 2014 The SmartenIT Consortium 4 Commercial in Confidence Questions Asked (3) and Replies Given  What is the impact of SDN/NFV-enabled cloud federations to ISPs? How will their traffic management be affected? What opportunities arise?  Impact: Not more, not less compared to traditional networks (unless proven otherwise), since “public” SDNs in a large scale are not yet interaction-tested; at best better performance  Traffic management may become cloud application-specific, advantage of dedicated QoE, including partial energy savings; drawback of yet unknown behavior of “interoperable” control  Opportunities: inter-domain business models may make it for an nth-time in networks? Advantage of cloud-driven control becoming interoperable (even formally tested); challenge of almost no direct ISP involvement any more

© 2014 The SmartenIT Consortium 5 Commercial in Confidence Questions Asked (4) and Replies Given  Can the value of information exchange between cloud operators (horizontally) and cloud operators and network operators (vertically) be assessed? What other issues apply (accounting, regulatory, privacy-related, etc.) and how can they be tackled?  Accounting: What is a useful, economically viable, technically feasible granularity of accounting data?  Regulatory: Is there a need to regulate federations at that level? Is any cloud federation access to be regulated? Are costs associated with such services to be regulated?  Privacy: Is the traffic management data exchanged between federated clouds private? Which facets of these control data are mandatory?

© 2014 The SmartenIT Consortium 6 Commercial in Confidence Questions Asked (8) and Replies Given  What are possible technological alternatives to develop and support cost- and energy-efficient and QoE-aware cloud federations, except SDN and NFV?  Traffic Management (TM) mechanisms for existing networks today lack amongst others decentralization, incentive- compatibility, and energy optimizations  New approaches from SmartenIT do exactly that within the given infrastructure by optimizing on two sides:  Operator-focused: Mechanism for Inter Cloud Communication (ICC), Dynamic Traffic Management (DTM), …  End user-focused: Home Router Sharing based on Trust (RB-HORST), Socially-aware TM for Efficient Content Delivery (SECD), QoE and Energy Aware Mobile TM (QoEnA), …
