The document discusses the SmartenIT project which aims to develop an incentive-compatible cross-layer network management solution. The solution will support cloud and overlay applications, content and cloud providers, networks, and end-users while considering quality of experience, social awareness, and energy efficiency. It will develop appropriate management mechanisms, qualify and quantify them in use cases, and demonstrate them in a prototype. Key challenges include traffic management, quality of service guarantees, balancing efficiency and energy consumption, and aligning stakeholder interests.

Motivation
! Future of the Internet:
! Cloud computing
! Application oriented
! Online social networks
(e.g. Facebook, Twitter)
! Mobile devices
! Overlay networks
! Consequences:
! Changing traffic patterns
! Increasing traffic volumes
! Communication paths with different quality levels
! Request: Application Traffic Management
! Coherent and integrated control in underlying heterogeneous networks
! Tighter integration of network management and overlay service functionality

SmartenIT Serves Management Requests
! Request for Application Traffic Management
! Effective support of scale, agility, flexibility
! Improved network management in all layers, on inter-domain
basis
! Promising approach to offer a business potential in operational
perspectives for all players involved
! Solution: SmartenIT
! Incentive-compatibility in network management for content
providers, overlay providers, 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

Challenges
! Technical and economic point of view:
! Traffic management for ISPs
! Quality-of-Service (QoS) guarantees
! Service combination
! Computational efficiency vs. energy consumption
! Limited resources of mobile devices
! Stakeholders interests

SmartenIT Challenges
! SmartenIT investigates trades-off, e.g., between efficient cloud resources
allocation and acceptable degradation of performance, Quality-of-
Experience (QoE) and social metrics depending on application.
! SmartenIT manages overlay applications needs in consideration of crucial
QoE metrics and social patterns.
! SmartenIT addresses services composed from components offered by
different cloud providers with new traffic management mechanisms to be
influenced by economic criteria on resource utilization and QoE.
! SmartenIT applies an incentive-based, energy efficient, and socially-aware
traffic management in the context of overlay applications.
! SmartenIT verifies models for energy consumption of mobile devices,
which can simulate overhead introduced by different management
approaches.
! SmartenIT designs traffic management solutions that employ appropriate
incentive mechanisms to constitute the deployment and use of overlay
applications more efficiently.

Scenarios in SmartenIT
! Inter-cloud communication
! Services: storage, CPU and RAM, application
! Integration of components
! Data exchange
! Exploiting OSN Information – Social Awareness
! Congestion growth
! Cost growth
! Traffic analysis

Scenarios in SmartenIT
! Inter-cloud communication
! Through many operators, where applications
demand for dedicated traffic quality levels
! Social Awareness
! Exploitation of meta-information extracted from
online social networks by network operators
! Global service mobility
! Integrated traffic management addressing trade-off
between energy efficient computation in the cloud
and energy consumption on mobile device
! Collaboration for energy efficiency
! Energy efficiency is pursued through collaboration
among stakeholders, e.g. between data centers, e.g.
between data center, ISP, end-users.

Example: Inter-cloud Communication
! Federated / interconnected clouds
! Comprised of smaller data centers /
clouds of different owners
! Collaboration, e.g. to extend
customer base, providing
specialized services, or
extending reachability
! Opportunities for traffic
management in SmartenIT
! No cross-cloud load balancer
! Traffic patterns of specialized
services
