OFELIA Workshop at ECOC 2011

29 July 2011

On 18th September 2011, in conjunction with the ECOC 2011 conference, OFELIA is organizing the workshop "OpenFlow Extensions Towards Multi-Layer And Multi-Domain Networks: OFELIA".

Chair: Hagen Woesner (EICT GmbH); Co-Chair: Siamak Azodolmolky (Univ. of Essex)

Date and time: Sunday, 18 September 2011, from 10:00 – 13:30

Location: Room F

Coffee Break: 11:00-11:30

Abstract: “While starting from a rather homogeneous Layer-2 hardware base, the OFELIA project (http://www.fp7-ofelia.eu) reaches out lower to integrate optical (i.e., circuit switching) and wireless networks into the OpenFlow control framework. To do so, description languages are needed that identify port and switch capabilities and cross-layer optimization techniques may lead to unified control plane of optical (circuit switched) and packet switched networks. Unified control plane based on OpenFlow concept is an interesting and challenging goal to achieve. Further on, multi-domain extensions to OpenFlow are to be investigated for large scale experiments. By breaking the vertical integration of networking gear OpenFlow allows application-specific monitoring, routing, and processing in the network rather than in the edges. Innovative ideas and applications based on OpenFlow paradigm will be presented in this workshop.”

OFELIA/CHANGE Summer School

The increasing complexity and fundamental problems in today's Internet architectural design and its deployment have led to significant research efforts in the area of Future Internet (FI) in Europe and Clean Slate Design (CSD) in the U.S. In this context, the OpenFlow initiative has recently caught the attention of researchers and even router vendors.

The objective of the OFELIA/CHANGE Summer School is to bring together PhD students and researchers who are currently working on future Internet topics such as:

* Principles of evolving future architectures

* New networking paradigms

* OpenFlow-related topics

* Programmable networks, NetFPGAs

* Network virtualization

* Measurements and analyses that characterize and quantify architectural limitations

* Discussions on interworking with the existing Internet and deployability

The program will contain presentations by well-known international experts on various topics.

PhD students are encouraged to submit a two pages extended abstract describing their current research results. After having submitted their abstract, all PhD students will be asked to comment and discuss some of the other submitted abstracts. This will allow the PhD students to discuss about their ongoing research with other PhD students prior to the summer school to ease discussion and cooperation among PhD students. The number of places is limited and PhD students who have submitted abstracts will have priority over other registrations.

Submissions

Submitted abstracts must be at most two pages long, including all figures, tables, references, appendices, etc. They must be formatted according to the standard ACM double column format.

Submission Deadline: July 22, 2011

Discussion phase: until August 15, 2011

Additional information and the submission website is available on the summer school's website : http://changeofelia.info.ucl.ac.be/

Open Call Information Day 9 Feb 2011

10 February 2011

FIREStation, the FP7 coordination action for a number of testbed-related projects, organized an Info Day where three projects (OFELIA, TEFIS and BonFIRE) jointly presented their plans for the execution of the Open Calls.

The Information day started with a general introduction to the Open Call process given by the new Head of Unit, Manuel Monteiro.

Some of the questions that were raised during the presentation have been summarized and answered in a separate FAQ section on the OFELIA web site.

The Coordinator presented OFELIA and stated that the project would be open for both experimentation and extension, but that in general the "pure experimentation" will be possible free of charge, so there is little need to pay for this. At the same time, most of the experiments will require some form of extension of the facility.

The afternoon started with a presentation of three coordinators of the OFELIA islands at UEssex, TU Berlin, and IBBT Ghent, introducing the status of the individual islands after the completion of the first deployment phase.

The meeting continued with presentations and discussions of new ideas coming from potential proposers. After some hesitation, a lively discussion sparked that suggested that the idea of the Open Calls should be followed and extended. We are now expecting a number of very good ideas for experimentation and extensions of the facility and are looking forward to working with the new partners we acquire through the process.

The call, details regarding the proposal process and a FAQ section can be found here.

OpenFlow tutorial in Berlin on Feb 7th, 2011

8 February 2011

Deutsche Telekom Laboratories hosted a day-long OpenFlow tutorial event on Feb 7th, 2011. 30 participants were present in Berlin and some additonal 20 connected online. This hands-on tutorial, given by Deutsche Telekom Inc. R&D Labs senior research scientist Srini Seetharaman, was aimed at giving researchers and research project organisers alike, exposure to the software components making up the OpenFlow software defined networking stack.

Volunteers from the OpenFlow research community at TU-Berlin/Deutsche Telekom Laboratories assisted participants as they took part in code-level exercises on their own laptops. Utilizing the Mininet virtual networking environment, participants constructed their own simple OpenFlow network topologies entirely in software. The tutorial culminated with each participant implementing his or her very own simple OpenFlow controller. The tutorial covered a wide range of topics and tools, including various software switch implementations, FlowSpace slicing with the FlowVisor, and visualization, measurement, and packet-level debugging tools. Operational experiences were also shared from the Stanford group, as valuable lessons learned from the numerous production deployments which will undoubtedly help others avoid common pitfalls.

The session concluded with a presentation and discussion session led by Stanford professor Nick McKeown on the future directions and expected developments for the OpenFlow protocol and community.

NEC OpenFlow Switches Hands-on Meeting

15 January 2011

While OFELIA adopts a common interface to access and use its OpenFlow enabled islands, all islands are widely autonomous allowing the local project team to implement and reflect the specific needs and constraints of the technologies provided by the individual islands, e.g. wireless or optical access systems.

In OFELIA several partners have decided to build their islands based on NEC IP 8800 devices as a mature basis for their deployment. NEC has joined the OpenFlow development quite early and NEC Laboratories Europe kindly hosted a hands-on meeting allowing interested OFELIA participants to learn about and use IP 8800 devices. This meeting took place on January 13 – 14, 2011 and gathered island team members of several OFELIA islands in Heidelberg.

Various strategies for slice isolation and their impact on performance were deployed and investigated. Beyond gathering hands-on experience with hardware devices, the Heidelberg meeting  served as first early integration meeting with remote participation of OFELIA developers and the island teams present in Heidelberg. OFELIA has adopted for its phase 1 a control framework based on  expedient developed at Stanford University and is actively participating in expedient’s continuous development. Various open issues concerning the expedient architecture and its further development were discussed and will be considered in the future development work.
