Abstract

See full text

Some embodiments provide a network system that includes several non-edge switching elements that are each for forwarding network data to other non-edge switching elements. The network system includes several edge switching elements that are each for (1) coupling to a set of network hosts and (2) forwarding network data to the non-edge switching elements and to the set of network hosts. Each of the non-edge switching elements of the several non-edge switching elements is further for forwarding network data to the several edge switching elements. The network system includes a set of network controllers for (1) receiving a definition of a logical switching element that couples to the sets of network hosts and (2) managing the several edge switching elements by configuring the several edge switching elements to forward network data between the sets of network hosts based on the definition of the logical switching element.
