 The basic architecture for an !OpenFlow network is a client - server (switch - controller) model involving a single controller and one or more switches. Networks can host multiple controllers. !FlowVisor virtualizes a single network into slices so that it can be shared amongst various controllers, and the newest !OpenFlow standard (v1.3.0) defines ''equal'', ''master'' and ''slave'' controllers to coexist as part of a redundancy scheme in what would be a single slice. A multi-controller scheme that isn't really explored yet is one where each controller has a different function, and cooperate.

 Thought was also put into the notion of autoconfiguration, in which the controllers discover other controllers by themselves, as opposed to being preconfigured through a file. References for this process included UPnP, although this becomes potentially very complicated. Using broadcast as the default behavior also compromises a good bit of the initial design, as the hierarchy had used the point-to-point TCP connections in order to maintain context as messages were passed between controllers (albeit poorly).
