G-Lab_Ener-G

The mission of G-Lab_Ener-G is to develop a comprehensive approach to the Future Internet architecture that includes energy efficiency as a fundamental principle. Key enablers for reaching this goal are virtualization and consolidation of communicational and computational resources and the exploitation of energy-saving features of hardware. The energy consumption of different components of the infrastructure is predicted by power consumption models. These models serve as a basis for an energy- and performance-aware, autonomous and self-organizing monitoring and management of physical and virtual resources. The envisioned management of physical and virtual resources aims at minimizing infrastructure energy consumption while assuring the provision of an application-tailored performance. Furthermore, communication and application layer protocols are analyzed regarding their support of an energy-efficient operation of Future Internet architectures.

• Load-based power consumption models of servers: Knowing the power consumption of servers allows for finding an energy-optimal allocation of virtual services to physical servers.
  
• Performance degradation model for service consolidation: Knowing the impact of consolidation on the performance of services allows for minimizing infrastructure energy consumption while complying with service level agreements on service performance.
  
• Energy- and performance-aware, autonomous and self-organizing management system of Future Internet architectures: The energy- and performance-aware management of physical and virtual resources allows for finding an optimal balance between infrastructure energy consumption and performance-level of virtualized services.
