Abstract

See full text

For a managed network including first and second managed switching elements that implement logical data path sets, some embodiments provide a method that establishes, from the first managed switching element, a network tunnel through a network to the second managed switching element. The network includes a set of unmanaged switching elements. Through the network tunnel, the network forwards logical network data to the set of unmanaged switching elements for the set of unmanaged switching elements to forward to the second managed switching element. The logical network is hidden from the set of unmanaged switching elements when the logical network data is forwarded through the tunnel.
