Recent publications on GEYSERS framework

An important task within a EU FP7 project is ensuring that its contents reach and impact industrial and research community, not only in Europe but also globally, so that all the project’s achievements are exploited and do not fall into oblivion. In GEYSERS, to ensure the widest possible impact of its results and output, there is a whole work package concentrating its efforts in the three directions that will grant the project significance: (1) dissemination, (2) exploitation and (3) standardization.

And the great effort dedicated by all the partners involved has given the deserved fruits; two important publications are to come this year: a paper in the International Conference on Computer Communications (INFOCOM) and a chapter in the Future Internet Assembly (FIA) book.

The INFOCOM paper, entitled “Energy Efficiency in integrated IT and Optical Network Infrastructures: The GEYSERS approach”, proposes an energy efficient design and operation of infrastructures incorporating integrated optical network and IT resources. Energy efficiency has become a trend topic on Information and Communication Technology (ICT) lately, as it has been estimated that it accounts for 4% of the primary energy consumption worldwide. To achieve this efficiency, GEYSERS relies on the virtualisation of the infrastructure resources and focuses on the energy savings that come from jointly optimizing the allocation and provisioning of optical network and IT resources. This paper quantifies for the first time the significant energy savings of a complete solution by defining energy models for both network and IT resources and an energy aware VI planning algorithm.

On the other hand, the FIA book chapter: “Bringing Optical Networks to the Cloud: an Architecture for a Sustainable future Internet” analyses the needs of the future internet and the challenges that are driving today’s Internet to the limit:

  • Enable ubiquitous access to huge bandwidth.
  • Coordinate IT and network service provisioning.
  • Deal with the unpredictability and burstiness of traffic.
  • Make the network energy-aware.
  • Enable secure and reliable services.
  • Develop a sustainable and strategic business model.

To address these challenges GEYSERS architecture is proposed, based on virtualisation, the definition of a new business model and the enhancement of current control and management planes to support dynamic service composition and orchestration over virtual infrastructures, which, at the same time, can be requested and resized on-demand. Figure below shows this architecture:

About Joan A. García-Espín

M.Sc. Joan A. García-Espín (joan.antoni.garcia@i2cat.net) is the Director of the Distributed Applications and Networks Area (DANA) of the i2CAT Foundation. He received his Telecommunication Engineering degree from the Technical University of Catalonia (UPC) in 2007. He wrote his Master Thesis in design and implementation of TE-enabled, DiffServ-aware MPLS networks for providing end-to-end QoS, also in 2007. He is a PhD candidate in the Telematics Engineering Department of the UPC. He is currently working in European projects FP7 GEYSERS (WP3 Leader) and GÉANT3. He has also participated in various European projects such as FP6 PHOSPHORUS and FP7 FEDERICA, and national (Spanish) projects including Enigma, Enigma Enhanced (Enigma II) and E3MS. He owns experience in optical networking, dynamic switching and management systems for networks, QoS and DiffServ for MPLS networks and infrastructure virtualisation. He is an active contributor to the NSI-wg and ISOD-rg gropus in the Open Grid Forum. His main research interests are cooperative agent interaction for network service provisioning, infrastructure virtualisation and network resource sharing and allocation.
