Phases in OFELIA

The OFELIA  facility will grow in three phases to, on the one hand provide an early access to the facility (after 6 months already) and, on the other hand to evolve during the project lifetime, incorporating the feedback of the user community and extending its reach to other test facilities.

Phase 1: Setup

Phase 2: Interconnection

Phase 3: Customization

OpenFlow controllers and switches in place

First local experiments concluded

Connect islands and extend OpenFlow experimentation to wireless and optics


Automate resource assignment and provide connections to other FIRE and non-European research facilities
>>> March 2011
>>> March 2012


 Phase 1: Setup of the islands

The first phase focuses on the goal to have a first implementation in a short time frame. The first stage of the facility will be available for users 6 month after the project start

The islands will be realized at 5 different universities and research institutions in Europe (TU Berlin, ETH Zürich, IBBT Gent, University of Bristol, I2Cat Barcelona).

The OFELIA facility will provide in Phase I researchers with a network slice that basically consists of three items:

  1. Network nodes that are OpenFlow 1.0 capable: in most cases these nodes are slices of NEC IP8800/S3640 switches.
  2. A (virtual) machine that will run the OpenFlow controller controlling the network slice.
  3. (Virtual) machines that act as network endpoints. Researchers will be allowed to SSH into these virtual machines to conduct their experiments (e.g., traffic generation and analysis).

To interact with their network slices, researchers will connect to the facility through a routed OpenVPN connection hosted at IBBT. From there on, each island will be reachable through bridged OpenVPN connections between the islands: in the future, this connectivity will be improved by installing dedicated GbE circuits.

Desks of researchers and students will be directly wired to the OFELIA infrastructure in the TUB and ETH islands, enabling experiments on more realistic traffic patterns. Besides the NEC switches other switches will be available in the UNIVBRIS and later on in the i2cat islands. IBBT will enable large scale experiments with OpenFlow soft switches on its shared iLab.t Virtual Wall (consisting of 100 nodes) and w-iLab.t wireless testbed (consisting of 200 nodes spread across three floors). More details are available here or on request.

 Phase 2: Interconnection of the islands

OFELIA’s islands will be connected. This connection will be based on a minimum of 1Gbit/s Ethernet tunnels in a star configuration (with the hub at IBBT in Gent).

 Phase 3: Customization of the facility to support the innovative usage scenarios defined by OFELIA customers

Integration of use cases that come in through the process of Open Calls that will be started after the first phase of initial setup. New partners will be invited into the consortium and the implementation of specific use cases will be supported by a dedicated funding.

The federation will extend to other FIRE facilities and the planned FIRE portal. Automated provisioning of OpenFlow slices across multiple islands will be available.
