OPTIMIZED RECONCILIATION IN A CONTROLLER-SWITCH NETWORK

A method performed by a switch in a software-defined network (SDN), the switch being communicatively coupled to a controller, is provided. The method includes performing a first flow action with respect to a first flow (e.g., deleting the first flow). The method further includes storing a first flow event data object, the first flow event data object indicating the first flow and the first flow action. The method further includes storing a first tag in association with the flow event data object. The method further includes generating a flow event message comprising the first flow event data object and the first tag. The method further includes sending the flow event message to the controller. 提供了一种由软件定义网络（SDN）中的交换机执行的方法，交换机被通信耦合至控制器。方法包括对第一流执行第一流动作（例如删除第一流）。方法进一步包括存储第一流事件数据对象，第一流事件数据对象指示第一流和第一流动作。方法进一步包括存储与流事件数据对象相关联的第一标签。方法进一步包括生成包括第一流事件数据对象和第一标签的流事件消息。方法进一步包括将流事件消息发送到控制器。
