Abstract: A method for changing a transmission path of packets transmitted from a first node to a second node in a software-defined network is provided. The method includes removing a flow entry corresponding to a first transmission path on a flow table of the first node after a plurality of first data packets intended to be transmitted to the second node are transmitted from the first node via relay nodes of the first transmission path. The method also includes transmitting a flush packet to the first node and setting the flush packet to be transmitted to the second node according to the first transmission path; and when the second node receives the flush packet and transmits a packet inquiry message corresponding to the flush packet to the controller, setting a flow entry corresponding to a second transmission path on a flow table of the second node.

Abstract translation: 提供了一种用于在软件定义网络中改变从第一节点发送到第二节点的分组的传输路径的方法。 该方法包括在经由第一传输路径的中继节点从第一节点发送要发送到第二节点的多个第一数据分组之后，删除与第一节点的流表上的第一传输路径相对应的流条目 。 该方法还包括向第一节点发送刷新分组，并根据第一传输路径将刷新分组设置为发送到第二节点; 并且当所述第二节点接收到所述刷新分组并将与所述刷新分组相对应的分组查询消息发送到所述控制器时，在所述第二节点的流表上设置与第二传输路径对应的流条目。
