Exciting Project Meeting in Barcelona - Tutorials on Trema, FOAM, Floodlight

2 March 2012

The OFELIA consortium met 22—24 February 2012 in Barcelona for its General Project Meeting.  Amongst other topics, the meeting was used to refine the architecture of the next version of the OFELIA control framework.

 

Special highlights at the meeting were tutorials about

 

Recognition of an OFELIA Partner for Contributions to ONF Standardization Work

20 January 2012

ONF Recognizes Standards Stars: https://www.opennetworking.org/?p=106&option=com_wordpress&Itemid=72

The Open Networking Foundation awarded Jürgen Quittek from NEC Europe Ltd. for his outstanding technical contributions to the Configuration and Management Working Group.

The Open Networking Foundation (ONF) accelerates the delivery and use of Software-Defined Networks (SDN) by standardizing OpenFlow (OF). SDN allows networks designers and operators to simplify networks by exploiting fundamental abstractions.

NEC Europe is a member of the OFELIA project consortium.

The OFELIA consortium intends to promote OpenFlow, to broadly discuss upcoming OpenFlow related issues and to contribute to the appropriate standard bodies.

Summer School Greatly Successful

17 November 2011

The summer school on flow-based switching and the OpenFlow technology was jointly organized by the EU FP7 projects OFELIA and CHANGE. The event took place in Berlin between November 7 and November 11, directly after the Internet Measurement Conference 2011 (November 2-4, also in Berlin). Overall, we hosted more than 54 PhD students and researchers, from the US, South America, and Europe.

The program comprised presentations by well-known international experts. The topics of the tutorials covered Future Internet topics and  network virtualization, including virtualization of the optical layer. Moreover, NetFPGA tutorials focused on OpenFlow as seen by researchers, hardware vendors, and network operators. An important part of the summer school were also poster sessions where students and other researchers presented their research ideas, received feedback and initialized detailed discussion about the several specific topics.

According to the feedback we received from the participants and the presenters, the summer school was a great success. The competitive program and the diversity of the presentations attracted many people from different communities, universities, and backgrounds.

Due to space constraints, we unfortunately had to reject some very interested contributions from additional students. The majority of the participants were not members of the OFELIA or CHANGE projects, but wanted to learn about the projects and OpenFlow technologies in general.

A detailed summary of the program including some pictures from the talks is available on the Summer School website: http://changeofelia.info.ucl.ac.be/SummerSchool/Program

Information about the posters titles, authors and abstracts is also available on the Summer School website: http://changeofelia.info.ucl.ac.be/SummerSchool/PosterSession

Internet2 Fall Meeting: OFELIA optical task force results presented

28 October 2011

During the Internet2 2011 Fall Meeting, University of Essex and ADVA Optical Networking jointly presented the outcome of the OFELIA optical task force regarding the extension of OpenFlow to support optical circuit switching at the session "An OpenFlow Enabled Optical Networking Paradigm for Future Internet Services".

UEssex and ADVA Optical Networking jointly organized and presented the session as part of the Internet 2 Fall member meeting. The session proposed an optical networking paradigm suitable for future Internet services enabled by OpenFlow. The OpenFlow technology supports the programmability of network functions and protocols by separating the data plane and the control plane, which are currently vertically integrated in routers and switches. Inter-working and integration of OpenFlow and GMPLS along with experimental setup and average flow setup time for different optical flows will be reported. The outcome of the OFELIA optical task force regarding the extension of OpenFlow to support optical circuit switching was presented in this session. A presentation was also given by RNP (Brazilian NREN), which is also a partner in EU Funded project FIBRE, to show the OpenFlow related efforts and their perspective on OpenFlow usage in circuit switching domain.

The presentation about the OFELIA optical task force results is available on the OFELIA website.

ECOC 2011 OFELIA Workshop attracted more than 30 participants

27 October 2011

More than 30 people participated in a lively discussion at the workshop. It turned out that there was indeed a common problem for most of the proposed ideas: a Hardware Abstraction Layer (HAL) for optical and more general for any OpenFlow switches appears necessary for the use of anything more specialized than a plain Ethernet switch. As an example, reconfigurable optical add/drop multiplexers (ROADMs) come in different flavors and switching capabilities (some all are freely configurable in the wavelength to be dropped, others not, some are directional, others not, and so on. In addition the nature of the interfaces is to be described, Meral Shirazipour suggested a GMPLS-like encoding of the interface types, arguing for an easier integration of OpenFlow-capable optical switches into existing GMPLS control planes. Other speakers argued for a more generic and less “legacy” description models.

Three talks on OpenFlow applications like greedy routing schemes and federation languages and resources complemented the workshop with topics going beyond the optical <-> OpenFlow integration. We would like to thank all speakers again for their highly interesting presentations and the opinionated discussion.

The list of speakers and the presentations are available via the OFELIA website.

 

OFELIA Demo at ServiceWave2011

26 October 2011

OFELIA will show a demonstration/presentation at ServiceWave2011 that takes place in conjunction with FIA 2011 in Poznan, Poland

Details at http://www.ict-fire.eu/events/eventview/article/future-internet-week.html and http://servicewave.eu/2011/

The OFELIA demo is part of the ServiceWave Demonstration Evening.

 

OFELIA demo at Open Networking Summit

20 September 2011

The OFELIA project was accepted to show a demonstration at the Open Networking Summit taking place 17 – 19 October 2011 at Stanford University.

The demonstration will show the live access to the control framework of the pan-European OFELIA OpenFlow testbed. OFELIA's scope is wider and more diversified than just offering yet another testing environment. A network slice in OFELIA consists of

  • Traffic sources and sinks (currently, Xen-based VMs or students’ traffic)
  • Commercial switches (partially virtualized through OpenFlow and FlowVisor)
  • Virtualized links (in project phase II links of dedicated bandwidth will be used)

The OFELIA demo as shown at the Open Networking Summit is demonstrating core features of OpenFlow and OFELIA:

  1. Dynamic creation of control plane slices suitable for deployment of existing or emerging control plane protocols and architectures for the Future Internet.
  2. Co-existence and co-operation of different control planes on the same physical network infrastructure including research and production slices.
  3. Dynamic creation of virtual machines for acting as data sinks and/or sources or for hosting control plane entities.
  4. Assignment of end systems and users to different network slices each controlled by a different control plane based either on user or network decision.

Intensive Discussions at Project Meeting in Zurich

20 September 2011

During the OFELIA project meeting in Zurich the project partners intensively discussed and made good progress on topics like the evolution of the OFELIA testbed and control framework architecture, slicing options, etc.  

The project meeting  took place 14 - 16 September 2011 in Zurich, Switzerland.

 

31 extended abstracts and posters submitted to Summer School

11 August 2011

We are happy to announce that for the OFELIA/CHANGE summer school 31 extended abstracts and posters were submitted from US, South America, and many different European countries. Now, the students have been asked to mutually comment and discuss their submitted extended abstracts. In addition, senior researchers review the submitted abstracts and provide constructive feedback to the PhD students. We are looking forward to an exciting week in November.
