Abstract:
A method for upgrading a set of controller nodes in a controller cluster that manages a plurality of forwarding elements in a way that minimizes dataplane outages. The method of some embodiments upgrades the control applications of a subset of the controller nodes before upgrading a decisive controller node. Once the decisive controller node is upgraded, the method switches the controller cluster to use a new version of the control applications.

Claim (Index 24):
The method of  claim 22 , wherein\n signaling the controller cluster comprises upgrading a decisive node in the plurality of controller nodes from the older controller state to the new controller state, upon completion of the upgrade of the decisive node, management of the forwarding elements is reassigned from the second subset of controller nodes executing the older controller state to the upgraded first subset of controller nodes and the upgraded decisive node.
