  The introduction of SDN in Service Providers' networks like GEANT is a
challenging task. Prototypes of new generation services have to exhibit
"carrier grade" characteristics, meet the high level expectations and
specialized needs of GEANT customers. In this demonstration, we present the SDN
based prototype of GEANT Open service, used by GEANT customers and approved
commercial partners to interconnect using Layer 2 circuits. Currently, this
service is delivered through a set of Open eXchange Points leveraging on legacy
solutions. The SDN based prototype has been realized on top of ONOS and
leverages on hardware switches for the data plane. During the demo, which runs
inside the GEANT Testbed Service, we show how operators can deploy services and
manage the SDN based infrastructure.
