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 the virtualization and consolidation of communicational and computational resources and the exploitation of energy-saving features of hardware. Specifically, the project addresses all successive layers in the protocol stack by providing energy saving mechanisms to the layers above on each respective layer.
In addition to the initial aim of achieving a more energy-efficient operation of the G-Lab research testbed, the project has evolved and is now on route to demonstrate an architecture that optimizes energy efficiency through virtualization without violating quality of service constraints. The envisioned architecture allows the easy setup of virtual routers to form virtual networks that fulfil an application-tailored quality of service (QoS) while minimizing the required energy resources.
- Achieving a more sustainable operation of future infrastructures by creating virtual overlay networks and mapping them energy-efficiently on the underlying physical hardware
- Providing application-tailored virtual networks with demand-driven quality of service
- Creating a working prototype running on the G-Lab testbed to show the real-life applicability of the approach
