WP4 - Instrumenting the network for power saving

WP4 Leader: Ivaylo Haratcherev (A-LBLF)

WP4 coordinates experimental activities, with implementation and testing of the technologies and procedures studied in the project. The nature of this experimental work and the required input from other WPs implies strong collaboration among partners as a prerequisite for successful completion of the activities in this WP. It is important to underline that joint experimental work has tremendous effects in terms of durable integration: people working side-to-side in a lab most likely establish durable personal links and share technical viewpoints. While many of those activities indeed involve several partners, just one Joint Experimental Activity (JEA) was formally defined, aimed at developing a power consumption monitoring and network configuration tool. Depending on the outcomes from the WP1, WP2, and WP3, and on demand from partners, more JEAs may be identified later. The results produced by this JEA(s) will be periodically communicated to all TREND partners, so that the outcome can be integrated with, and used as feedback for, the activities in the other WPs. Moreover, the primary objective of this WP is to prove the effectiveness of the approaches studied in other WPs. Results and learned lessons of WP4’s experimental activities will be proactively spread to interested parties in the international technical community.

The research, integration and dissemination work of WP4 is structured according to the following three Technical Domains:

  • Network-wide energy measurement and management: Extend existing network management systems in order to measure and report on energy consumption of network elements and the overall network as well as to analyse and validate the overall network’s energy saving achievements.
  • Platforms, testing and validation: Build experimental platforms and testbeds. Conduct simulations and tests on the new and on already existing platforms on energy-efficient approaches identified in other WPs at the level of network elements, management algorithms, and protocols and validate achieved energy savings.
  • Field trials: Introduce power-saving policies in user communities and evaluate the impact of those policies in the field. Such user communities will be within a university or a research center – in the premises of individual partners.
    The following Joint Experimental Activity (JEA) is defined for WP4. More JEAs may be defined in the lifetime of TREND.
  • JEA4.1 (related to Technical Domain 4.1): Development of a tool for monitoring and controlling the power consumption of networking infrastructures (interest expressed by PoliTO/CNIT/UTH).
  • The partners in this JEA will address a joint development of a tool to monitor the power consumption in real time, and to control the configuration of the operational parameters of network devices and protocols to reduce power consumption. On-off switching of devices as a function of traffic fluctuations is a simple example of these control actions. The CNIT campus network and a wireless testbed at UTH will be used as testing facilities for this activity.

The following tasks are defined for WP4:

  • Task 4.1 [M03-M36]: Implementation, integration, and dissemination activities related to JEA4.1 “Development of a tool for monitoring and controlling the power consumption of networking infrastructures”
  • Task 4.2 [M01-M30]: Implementation, integration, and dissemination activities related to building testbeds and running tests on them.
  • Task 4.3 [M06-M36]: Implementation, integration, and dissemination activities related to field trials.
