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


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.


SmartenIT Approach to Address Challenges

! Use-case driven approach !  Consideration of different scenarios !  Identification of relevant applications !  Stakeholder analysis and

business modeling !  Definition of appropriate use-cases

! Theory and Modeling !  Development of (distributed) traffic

management solutions !  Requirement driven SmartenIT architecture !  Theoretical and simulative evaluation

! Proof-of-concept implementation !  Agile network management and operation framework !  Validation and evaluation

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.










Goal: Optimize QoE, energy efficiency of network infrastructure and end user devices, inter-domain and inter-cloud traffic and emerging costs


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


Selection of Applications ! Expert user survey among project partners ! Goal: identification of relevant applications for those scenarios
