1. Panel on “Cloud Federations and SDN/NFV: the highways towards improved QoE, Cost, and Energy Efficiency” Socially-aware Management of New Overlay Application Traffic combined with Energy Efficiency in the Internet European Seventh Framework STREP FP7-2012-ICT-317846 http://www.smartenit.eu Burkhard Stiller, University of Zürich FIA 2014, Athens, Greece, March 19, 2014

2. and Panel Relation 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 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.

3. 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

4. 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

5. 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?

6. 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), …
