| 3 | | At InstaGENI racks, FOAM was the aggregate manager used with FlowVisor (FV) to allow experimenters to reserve SDN resources at a rack. A single OpenFlow VLAN instance was manually provisioned at the racks and FV allowed "slicing" of this instance via IP subnets. Hence, each researcher was allocated an IP subnet (a priori) to conduct SDN experiments. FOAM and FV were also used at the GENI Mesoscale network to facilitate network programmability at the GENI core. However, FV is not actively maintained. Furthermore, with the transition from the Mesoscale to AL2S core network as the new GENI core network and the advent of the "OpenFlow over Stitching" service, FV and FOAM are no longer necessary. |
