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.

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

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

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?

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), …
