    2424== Inter-campus Connectivity Options ==
    25 As shown in Figure 2, the GENI data plane can include both layer 3 and layer 2 options, using the existing campus connections to regional and national research networks on each campus.  Layer 2 data planes in particular allow experimenters to work with protocols other than TCP/IP in their experiments.  In addition to the data plane, most GENI experiments require layer 3 IP connectivity for out-of-band control and monitoring, and this control path differs from the experimental data path. For example, OpenFlow may require TCP/IP connections from an experimenter’s laptop to configure OpenFlow software Controllers and TCP/IP connections between the OpenFlow Controllers and OpenFlow-capable switches.  GENI aggregate managers also typically communicate with GENI clearinghouses using TCP/IP.  This section lists some common layer 2 data plane options.
