FIRE RoadmapOFELIA: Vertigo use case
Challenge:
A recent development in network virtualization is the use of FlowVisor, which exploits the specific features of an OpenFlow-controlled network, sharing the same hardware forwarding plane among multiple virtual networks. However, the rigid slicing mechanism of FlowVisor forces researchers to keep the network topology of their experiments strictly based on the physical topology of the underlying physical infrastructure.

OFELIA: Experimental facility at Essex
OFELIA: OpenFlow in Europe – Linking Infrastructure and Applications
The OFELIA facility is based on OpenFlow, a currently emerging networking technology which facilitates virtualization and control of the network environment through secure and standardized interfaces.
A set of five islands based at University of Essex (UK), ETH (Switzerland), I2CAT (Spain), TUB (Germany) and IBBT (Belgiun) creates a distributed OpenFlow infrastructure multi-layer and multi-technology networks experimental facility. The facility will offer access to a diverse technology including Ethernet, optical and wireless domains. The islands are connected by multiple 1GE links to the GEANT network and therefore it can support direct user access to the facility.
OFELIA also provide access to very advanced ultra high definition video sources (4K 3D and 8K) which can generate high bit rate data streams (up to 20 Gbps) and used as test applications for experiments carried over the facility.
Web-based tools and Web-services for flow based virtual Infrastructure will enable network researchers across Europe to gain access to the testbed. They will be able to request network resources to setup their L1, L2 or hybrid L1-L2 experimental infrastructures (virtual infrastructure) which they can control, experiment, monitor and also gather statistics of their experiment and results.
