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 35):
The method of  claim 22 , wherein:\n each controller node executes a version of a network control application; and upgrading a controller node from an older controller state to a new controller state comprises upgrading the controller node to execute a newer version of the network control application.
