SmartenIT Take-off and Panel Relation
Commercial in Confidence
 Internet with the move to support clouds and their as
well as many different overlay applications
 Coherent and integrated control in underlying
heterogeneous networks such as by SDN/NFV
 Tighter integration of network management and overlay
service functionality to improve QoE, Cost, and
Energy Efficiency
 SmartenIT
 Socially-aware Management of New Overlay Application
Traffic combined with Energy Efficiency in the Internet
... 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
Commercial in Confidence
 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
Commercial in Confidence
 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
Commercial in Confidence
 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, incentivecompatibility, 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), …
