Abstract:
1. A network controller for managing a set of physical interconnection switching elements that connect segmented networks to a shared physical interconnection network, the network controller comprising: a control application for (i) receiving input logical control plane data that defines a logical switching element in terms of a set of tables, the logical switching element for logically connecting a plurality of network segments operating within at least two different segmented networks by coupling logical ports of the logical switching element to the network segments, and (ii) translating the received input logical control plane data into logical forwarding plane data that defines the logical switching element in terms of a first set of flow entries; and a virtualization application for translating the logical forwarding plane data into physical control plane data that defines the logical switching element in terms of a second set of flow entries that contains the logical forwarding plane data in addition to data binding the logical ports to the physical interconnection switching elements, wherein the physical control plane data is for distribution to the physical interconnection switching elements in order to direct forwarding of network data by the physical interconnection switching elements.
