Econet: Low Energy Consumption Networks


    1 Oct, 2010


    31 Dec, 2013


    EU FP7


The project consortium was led by Consorzio Nazionale Interuniversitario Per Le Telecomunicazioni, Italy (CNET) and funded by Framework Programme 7 under Contract no. INFSO-ICT-258454.

The Econet project preceded the foundation of Entwine but it involved two members of Entwine and its objectives were in keeping with Entwine’s mession. These were:

Nowadays, it is widely recognised that the sole introduction of low consumption silicon elements will not be sufficient to effectively curb tomorrow’s network energy requirements. Based on this assumption, the ECONET project will investigate, develop and test new capabilities for the Future Internet devices enabling the efficient management of power consumption so to strongly reduce the current energy waste.The ECONET project will be devoted at re-thinking and re-designing network equipment towards more energy-sustainable and eco-friendly technologies and perspectives. The overall idea is to introduce novel green network-specific paradigms and concepts enabling the reduction of energy requirements of wired network equipment by 50% in the short/mid-term (and by 80% in the long run) with respect to the business-as-usual scenario.To this end, the main challenge is to design, develop and test novel technologies, integrated control criteria and mechanisms for network equipment allowing energy saving by dynamically adapting the device capacities and consumptions to current traffic loads and user requirements.The ECONET project will focus its research and development efforts in three main research axes:- In the first axis, novel network-specific HW/FW technologies will be developed to optimise the power management features.- The second axis will be devoted to develop local and distributed frameworks for dynamic optimization of the trade-off between energy consumption and network performance.- The last axis will focus on the design of a Green Abstraction Layer for interfacing the novel low-level green capabilities with OAM frameworks in a common and standard way.The ECONET project will deliver novel energy-aware device prototypes on which large-scale demonstration tests will be conducted. With a significant dissemination effort, the project will aim at maximising its impact on industrial and network operator communities as well as on standardization bodies.

The DCU involvement was to lead the “workpackage” developing the Green Adaptation Layer, the central layer of the energy-aware network stack developed by the Econet consortium. We developed an energy-efficient router that used frequency scaling to match router performance to demand implemented on the NetFPGA platform programmed in VHDL. This testbed would subsequently be extended to support OpenFlow in the H2020-funded Input project.

Green Abstraction Layer

A key achievement of the project was to get the Green Adaptation Layer incorporated into an ETSI standard, namely ETSI ES 203 237 (see Green Abstraction Layer standard to manage energy consumption of telecom networks for more information).
