 Abstract The Internet has seen a strong move to support new overlay
applications offered over the cloud, which demand for a coherent and integrated
control in underlying heterogeneous networks in a scalable, resilient, and cost-efficient
manner. A tighter integration of network management and cloud service
functionality can lead to cross-layer optimization of operations and
management, thus, being a promising approach to offer a large business
potential in operational perspectives for all players involved. In this paper
the SmartenIT approach is presented, which targets at a cross-layer traffic
management by providing incentives to the involved stakeholders, i.e., providers
of cloud-based applications, network operators, cloud operators, and end-users,
to ensure a QoE-awareness. SmartenIT designs and develops traffic management
solutions and mechanisms to meet accordingly special application requirements
and to address efficiently load and traffic patterns, exploiting also social information
in terms of user relations, interests and behaviour patterns. Additionally, the
energy efficiency with respect to both end-user devices and underlying
networking and cloud service provisioning infrastructure is tackled to ensure
an operationally efficient management. Furthermore, this paper describes three
scenarios of major interest to SmartenIT and discusses the possible impact of
the SmartenIT approach on metrics of interest associated to each involved
stakeholder. Finally, a conceptual architectural framework is introduced and major
design axes and describe key functionalities are described; this conceptual architecture
constitutes the basis for the development of the SmartenIT architecture. Full paper Link to full paper is to be provided soon. |
