Abstract
Some embodiments provide a network architecture that includes several lower level managed switching elements for forwarding network data to several of network hosts. The network architecture includes a set of higher level managed switching elements. The several lower level managed switching elements and the set of higher level managed switching elements implement several logical datapath sets. Communication channels are established among the several lower level managed switching elements and the set of higher level managed switching elements based on a mesh topology.
