OFELIA OpenFlow Experimental Facility Infrastructure and Functionality Continues to Exist and Remains Open for Experiments

October 22, 2013 - The EU-funded project OFELIA announced the continued availability, maintenance and further development of the pan-European OFELIA OpenFlow-based testbed facility. The OFELIA facility comprises ten federated islands dispersed over Europe and Brazil. Cross-island experiments are enabled with OCF, the OFELIA Control Framework. There are a number of ongoing collaborations and interconnections with other OpenFlow infrastructures.

After three years of work and collaborations, at the end of the EU project OFELIA, the OpenFlow-based experimental testbed facility OFELIA comprises ten federated islands dispersed over Europe and Brazil. The facility will not end with the EU project. OFELIA Island owners and project members agreed to keep the facility up and to continue use, experiments and further development of the OFELIA Control Framework.

The "OFELIA Foundation Task-Force" was set-up and focuses on four aspects to sustain and coordinate OFELIA's software development: academic and industrial relations, software development, network connectivity

The OFELIA OpenFlow-based experimental facility is a pan-European experimental network facility that allows researchers to not only experiment "on" a test network but to control and extend the network itself precisely and dynamically. OpenFlow is a key component of the new networking paradigm called Software Defined Networking (SDN). Generally, the use of the OFELIA facility is provided "as is" as a free-of-charge best-effort service. Any user accepting the usage policy is welcome to experiment on the OpenFlow-enabled testbed.

The project OFELIA was supported within the 7th Research Framework programme of the European Community. The project consortium consists of the following organizations: European Center for Information and Communication Technologies (EICT), Germany; Deutsche Telekom Laboratories, Germany; University of Bristol, UK; i2CAT Foundation, Research and Innovation in the Internet Area, Spain; Technische Universität Berlin, Germany; NEC Europe Ltd., U.K.; Interdisciplinary Institute for Broadband Technology (iMinds), Belgium; Eidgenössische Technische Hochschule Zürich, Switzerland; Stanford University, USA; ADVA Optical Networking SE, UK; Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT), Italy; Center for REsearch And Telecommunication Experimentation for NETworked communities (CREATE-NET), Italy; Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) , Spain; Lancaster University, UK; Instituto de Telecomunicações Aveiro (ITAV), Portugal; University of São Paulo, Brazil; Federal University of Uberlândia, Brazil.

GÉANT and OFELIA Cooperate to Provide OpenFlow-based Test Network Facilities

August 22, 2013 – GÉANT and the EU-funded project OFELIA are cooperating to provide OpenFlow-based test network facilities and have set-up a multi-domain OpenFlow testbed environment. This joint OpenFlow facility is open to be used for experiments and had been demonstrated at ONS 2013, FIA Dublin and TNC 2013.

OpenFlow and Software Defined Networking (SDN) as a new networking paradigm provide a platform to allow new and innovative networking protocols and software to be developed and tested. The current TCP/IP protocols were developed over 30 years ago to support slow speed, unreliable networks and the demands of high performance, low delay networking require radical innovation in this core technology.

The interest in SDN and OpenFlow has recently increased amongst the industry as well as the academia. Many big events and initiatives have been delivered by those actors in the recent years and months, and big names of the IT and Networking world have backed the SDN-OpenFlow tuple. Because of that, many have followed the door that Stanford and others opened, and many more will follow.

By jointly developing OpenFlow-based testbed facilities, GÉANT and OFELIA are giving Europe's researchers the ability to test these new systems across networks that are representative of real-world commercial networks and ensure Europe is at the forefront of technology research into internetworking.

GÉANT and OFELIA offer an infrastructure to try out and evolve OpenFlow-based SDN solutions. This infrastructure, joining GÉANT and OFELIA OpenFlow-based islands, spans over multiple, geographically dispersed locations and enables experiments to combine and utilize their various resources, tools and features. The facility is unique in size and completeness.

The OFELIA experimental facility comprises a set of ten, interconnected islands, which create a diverse OpenFlow infrastructure that allows experimentation on multi-layer and multi-technology networks provided by the different islands. Generally, the use of the OFELIA facility is provided "as is" as a free-of-charge best-effort service. Any user accepting the usage policy is welcome to experiment on the OpenFlow-enabled testbed.

The GÉANT OpenFlow facility is a test-bed environment deployed on top of the GEANT production network. The facility is collocated with (5) of the GEANT PoPs in Vienna, Frankfurt, London, Amsterdam and Zagreb. It is built on software based network resources; OpenFlow switches referred to as OvS and network links interconnecting them. The priority is to deliver seamless slice request submission, instantiation, and decommissioning functionality to the end-user/researcher through the GEANT OpenFlow Control Framework (GOCF), empowered by the OFELIA Control Framework (OCF).

The orchestration software deployed on top of the GÉANT OpenFlow Facility to implement the management plane functionality is the OCF that has been adapted to fulfill the GÉANT OpenFlow Facility requirements.

The OFELIA Control Framework (OCF) is a set of software tools for testbed management. It controls the experimentation life cycle; including reservation, instantiation, configuration, monitoring. It hides the complexities involved in single and federated island setups, still providing enough information so that experimenters can program their environment using heterogeneous, scalable resources. The OCF is available under BSD license and is being actively developed and used as a production control framework by the OFELIA FP7 project testbed.

OFELIA 2nd Open Call for OpenFlow Experiments Success and New Partners

OpenFlow Experimental Facility Infrastructure and Functionality to be Extended as a Result of the Second Open Call

July 26, 2012 – The EU-funded project OFELIA announced the success of its second Open Call for using and extending the pan-European OFELIA OpenFlow-based testbed facility. Four proposals (out of 17 submitted) were selected and will extend the infrastructure and functionality of the facility.

The OFELIA project has set-up and maintains a pan-European experimental network facility that allows researchers to not only experiment “on” a test network but to control and extend the network itself precisely and dynamically. The OFELIA facility is based on OpenFlow, a currently emerging networking technology that allows virtualization and control of the network environment through secure and standardized interfaces. OpenFlow is a key component of the new networking paradigm called Software Defined Networking (SDN). Generally, the use of the OFELIA facility is provided "as is" as a free-of-charge best-effort service. Any user accepting the usage policy is welcome to experiment on the OpenFlow-enabled testbed.

With its second Open Call the project asked for proposals to extend the experimental facility to enable advanced use and experimentation. Specifically solicited were proposals addressing functional diversity of experimental capabilities, specific measurements and evaluations that need extensions of the already available infrastructure, as well as functional and usability enhancements of the experimental facility.

17 proposals were submitted to the OFELIA open call, in total asking for 1.97 M€ of EU budget contribution, about five times the available budget. The four proposals selected by independent reviewers, which will be integrated into OFELIA, are:

OpenFlow/PCE integration [Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), Spain]: Functionally enhance the OpenFlow control plane, by introducing new path computation architectures and related new network operating system applications. By formally decoupling the path computation function involved in the provisioning of connectivity services, the architecture will be able to offload computations to (optionally remote) dedicated servers and to perform load balancing, distributing path computation tasks amongst a pool of such servers. The main objective is to integrate the notion of (hierarchical) PCEs in the OpenFlow centralized control model.

OpenFlow-assisted VoD [Lancaster University, UK]: QoE Experimentation and Evaluation. Here OpenFlow will be exploited to support transparent caching of large media objects in a wide-area network, with extensions to the OpenFlow interface where necessary. The goal is to optimize the repeated delivery of identical content, while allowing the applications deployed across the network to continue using apparently simple unicast flows. Furthermore, the impact of delivery mechanisms on the users' perceived Quality-of- Experience (QoE) will be evaluated by applying an established QoE measurement framework to the evaluation of the OpenFlow-based transparent caching system.

EDOBRA [Instituto de Telecomunicações Aveiro (ITAV), Portugal]: Extending and Deploying OFELIA in BRAzil, gathers a team of three different institutions from Portugal and Brazil: the Instituto de Telecomunicações (IT), from Aveiro, Portugal, the University of São Paulo (USP), and the Federal University of Uberlândia (UFU), both from Brazil. This proposal aims at extending the capacity of Software Defined Networks approaches, such as OpenFlow, by enabling the support for vertical handovers using IEEE 802.21 enhanced mechanisms, and by deploying the Entity Title Architecture, a clean slate approach that provides seamless multicast and mobility based on this OpenFlow substrate. EDOBRA will increase the physical coverage of OFELIA by deploying a new node in Brazil, which will improve future Internet research and experimentation by providing these approaches to a broader community.

EMOTICON [Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT), Italy]: Extending OpenFlow for Unified Management and Control of Cloud Data Center Resources. This aims at enhancing OFELIA with a novel functionality that enables the unified control and management of IT and network resources in Cloud Data Centers. New virtualization-aware networking architecture whose advanced traffic engineering capabilities are enabled by OpenFlow-based Virtualization-aware Networking (OFVN) systems. The OFVN architecture will be designed with scalability in mind, so as to guarantee performance requirements concerning communication among the servers even though the Data Center continues to grow in size. EMOTICON will also contribute to increase the physical extension of the OFELIA facility by adding a new island located in Pisa, that consists of two different CNIT sites (National Laboratory of Photonic Networks and Dept. of Information Engineering - University of Pisa) interconnected through a WDM optical ring.

 

The project OFELIA is active in the 7th Research Framework programme of the European Community. The project consortium consists of the following organizations: European Center for Information and Communication Technologies (EICT), Germany; Deutsche Telekom Laboratories, Germany; University of Essex, UK; i2CAT Foundation, Research and Innovation in the Internet Area, Spain; Technische Universität Berlin, Germany; NEC Europe Ltd., U.K.; Interdisciplinary Institute for Broadband Technology (IBBT), Belgium; Eidgenössische Technische Hochschule Zürich, Switzerland; Stanford University, USA; ADVA AG Optical Networking, UK; CNIT, Italy; CREATE-NET, Italy.

Researchers Are Invited To Use The Unique Experimental Facility For Future Internet Research Based On OpenFlow Technology

August 22, 2011 – The EU-funded project OFELIA announces the public availability for experiments of its European network facility based on OpenFlow technology. Any user accepting the usage policy is welcome to experiment on the OpenFlow-enabled testbed offered at five facilities in Europe. Usage of the OFELIA facility is provided as a free-of-charge best-effort service.

The OFELIA project has created a unique experimental facility that allows researchers to not only experiment “on” a test network but to control and extend the network itself precisely and dynamically. The OFELIA facility is based on OpenFlow, a currently emerging networking technology that allows virtualization and control of the network environment through secure and standardized interfaces. OpenFlow separates control and forwarding planes, enabling users to program their networks by extending the network controller. Five facilities (also called OFELIA islands) offering an OpenFlow infrastructure are available to do experimentation on multi-layer and multi-technology networks. The experimentation space allows for flexible integration of test and production traffic by isolating the traffic domains inside the OpenFlow enabled network equipment.

Based on OpenFlow 1.0, OFELIA offers a private test environment for the development and testing of new network applications. It integrates OpenFlow-enabled hardware devices of various vendors (e.g. NEC, ADVA) and sets of virtual machines for traffic generation. The OFELIA facility enables network research by deploying different network topologies.

With this public offer, OFELIA concludes its first development phase by making five facilities in Ghent (Belgium), Berlin (Germany), Zurich (Switzerland), Colchester (UK), and Barcelona (Spain) available for experiments. In the next phase, OFELIA’s facilities will be interconnected to a single network distributed across Europe. The connectivity between the islands will be based on Gbit/s Ethernet tunnels. This second phase will then enable experiments spanning two or more islands.The project OFELIA is funded within the 7th Research Framework programme of the European Community. The project consortium consists of the following organizations: European Center for Information and Communication Technologies (EICT), Germany; Deutsche Telekom Laboratories, Germany; University of Essex, UK; i2CAT Foundation, Research and Innovation in the Internet Area, Spain; Technische Universität Berlin, Germany; NEC Europe Ltd., U.K.; Interdisciplinary Institute for Broadband Technology (IBBT), Belgium; Eidgenössische Technische Hochschule Zürich, Switzerland; Stanford University, USA; ADVA AG Optical Networking, UK.

The Unique Experimental Facility For Future Internet Research Based On OpenFlow Technology To Be Used And Extended

May 27, 2011 – The EU-funded project OFELIA announced the success of its first open call for using and extending the pan-European network facility based on OpenFlow enabled technology. 21 proposals were submitted to the OFELIA open call, summing to a total budget of 4.8 million Euros (3.5 million Euros requested funding). The proposals came from nine different member states of the EU (mainly Germany, Greece, and Italy), and from Norway, Turkey, Israel, China. The call is ten times overbooked in terms of available funding.

The OFELIA project creates a unique experimental facility that allows researchers to not only experiment “on” a test network but to control and extend the network itself precisely and dynamically. The OFELIA facility is based on OpenFlow, a currently emerging networking technology that allows virtualization and control of the network environment through secure and standardized interfaces.

The first OFELIA open call asked for proposals to enable advanced use and experimentation of the OFELIA pan-European experimental facility. Specifically, the project solicited proposals regarding (a) extension of the existing experimental facility, (b) measurement and evaluation and (c) functional enhancement of the experimental facility for experiments.

The evaluation of proposals in cooperation with the European Commission and the integration of the winning proposals as new partners in OFELIA are currently ongoing.

“Many of the proposals came with brilliant ideas.” said the OFELIA project coordinator Hagen Woesner, “We think of what to do with the proposals that we cannot accept this time, because we have a technical interest of seeing your brilliant ideas run on OFELIA as well as the general interest of growing a community around OFELIA. We plan a workshop in autumn 2011, where we would give all proposals the opportunity to present, discuss their ideas and potentially join forces for new consortia. It would be a shame losing the momentum that OpenFlow and OFELIA currently have in Europe”.

Generally, the usage of the OFELIA facility is provided "as is" as a free-of-charge best-effort service. Any user accepting the usage policy is welcome to experiment on the OpenFlow-enabled testbed. Based on both, experiences from the operation of the facility and feedback from the user community, open calls are issued to extend the experimental facility with additional, new use cases and scenarios. A second open call will be issued in about one year (expected deadline March 2012).

The project OFELIA is active in the 7th Research Framework programme of the European Community. The project consortium consists of the following organizations: European Center for Information and Communication Technologies (EICT), Germany; Deutsche Telekom Laboratories, Germany; University of Essex, UK; i2CAT Foundation, Research and Innovation in the Internet Area, Spain; Technische Universität Berlin, Germany; NEC Europe Ltd., U.K.; Interdisciplinary Institute for Broadband Technology (IBBT), Belgium; Eidgenössische Technische Hochschule Zürich, Switzerland; Stanford University, USA; ADVA AG Optical Networking, UK.

OFELIA Lays Corner Stone For OpenFlow Enabled Research Facility In Europe

Europe Builds Unique Experimental Facility For Future Internet Research Based On OpenFlow Technology

 

On October 1st 2010 a consortium of 10 partners, including operators, vendors and research institutions, launched the research collaborative project OFELIA (OpenFlow in Europe: Linking Infrastructure and Applications; http://www.fp7-ofelia.eu/) that will set-up an experimental facility based on OpenFlow technology. The project will receive 4.45 million Euros funding from the European Commission’s FP7 ICT Work Programme.

The increasing complexity of deployment and use of today’s Internet has highlighted fundamental problems in its architectural design. This has led to significant research efforts in the area of Future Internet in Europe and Clean Slate Design in the U.S. These research initiatives require appropriate experimental facilities to be established.

The OFELIA project will address these needs by creating a unique experimental facility that allows researchers to not only experiment “on” a test network but to control the network itself precisely and dynamically. The OFELIA facility is based on OpenFlow, a currently emerging networking technology that allows virtualization and control of the network environment through secure and standardized interfaces.

Five interconnected islands based on OpenFlow infrastructure will be created to allow experimentation on multi-layer and multi-technology networks. OFELIA is to provide an experimentation space which allows for flexible integration of test and production traffic by isolating the traffic domains inside the OpenFlow enabled network equipment. This allows for providing realistic test scenarios and for seamless deployment of successfully tested technology.

The OFELIA experimental facility will use OpenFlow enabled carrier grade equipment from NEC thus allowing performance tests under production conditions.

The OFELIA project will invite experimenters in Europe to bring their use cases and scenarios and to use the OFELIA test facility. Two open calls will be published offering experimenters additional funding from the OFELIA project for conducting their experiments. The first call will be published at the beginning of 2011. Details can be found on the project website.

Further, OFELIA wants to cooperate with related international efforts such as AKARI in Japan and GENI in the US.

The OFELIA project duration is from October 2010 to September 2013. The project consortium consists of the following organizations:

  • European Center for Information and Communication Technologies (EICT), Germany
  • Deutsche Telekom Laboratories, Germany
  • University of Essex; UK
  • i2CAT Foundation, Research and Innovation in the Internet Area, Spain
  • Technische Universität Berlin, Germany
  • NEC Europe Ltd., U.K.
  • Interdisciplinary Institute for Broadband Technology (IBBT), Belgium
  • Eidgenössische Technische Hochschule Zürich, Switzerland
  • Stanford University; USA
