     3This is an example topology of a campus OpenFlow network, designed to allow experimenters to access the GENI network core in a variety of ways depending on their needs. In particular, it describes a single topology for connecting resources at campuses to a local OpenFlow network, which then offers three options for experimenters to link those resources to inter-campus VLANs.

    5  1. Connect directly to one or more pre-provisioned [wiki:ConnectivityHome core VLANs], without using any campus !OpenFlow resources. This is a very simple option for experiments that don't need to use !OpenFlow campus resources at all, and merely want to access the GENI network core.
     5Those options for experimenters are:

    7  2. Use !OpenFlow to connect to one or more pre-provisioned [wiki:ConnectivityHome core VLANs], via a cross-connect cable that translates from a campus !OpenFlow VLAN onto the core VLANs. This is a fairly simple option for experiments that want to use !OpenFlow campus resources, and can use existing core VLANs.

    9  3. Use !OpenFlow to connect to any [wiki:ConnectivityHome core VLANs], by having !OpenFlow configure the switch to do VLAN translation. This is a more complicated option for experiments that want to use !OpenFlow campus resources, and need to use VLANs that aren't provisioned with a physical cross-connect for whatever reason (e.g. large numbers of VLANs, dynamically provisioned VLANs, etc).

    1113Most !OpenFlow experiments will probably be able to use the second option, which offers a good combination of performance, features, and ease of use.
