Abstract
Some embodiments provide a network control system that includes a network controller and a set of hosts on which a set of managed forwarding elements operate. The network controller computes forwarding state information and pushes the computed forwarding state information to a set of managed forwarding elements to define forwarding behaviors of the managed forwarding elements. The managed forwarding elements receive the forwarding state information from the network controller and directly exchange with each other updates to the forwarding state information. The updates are exchanged between the managed forwarding elements without a network controller relaying the updates.
