OpenFlow aggregates in GENI typically use Expedient as their aggregate manager, along with the Opt-In Manager. The OIM is currently packaged separately, but Expedient and the OIM each depend on the other.

Opting in your traffic

If you allocate a shared resource that connects to an OpenFlow aggregate (e.g. a MyPLC plnode or ProtoGENI host), you'll typically also need to reserve some OpenFlow resources. When you do this, your reservation request goes to the Opt-In Manager, and a local Expedient OIM admin needs to approve your request before your sliver actually becomes live. The OIM admin isn't notified of your request, so you'll usually want to contact them to ask them to opt in your sliver. Here's a list of Expedient aggregates, and contact info for the OIM admins:
