Abstract
A method performed by a network element, for notifying a controller of a change to a packet forwarding configuration of the network element. The network element is separated from the controller by a communication channel. The method includes determining the change to the packet forwarding configuration of the network element. The packet forwarding configuration specifies how packets are to be forwarded by the network element. The method also includes actively notifying the controller of the change to the packet forwarding configuration by sending a message to the controller over the communication channel. The message, in addition to indicating the change, also indicates at least one detail about the packet forwarding configuration after the change.
