Abstract: A flow entry delivery method and a communication system are provided. The communication system includes a controller and N switches. After receiving a packet-in message sent by a source switch, the controller determines a forwarding path for forwarding to-be-forwarded data. Then, the controller generates a corresponding flow entry for each of the N switches in the forwarding path separately, and generates a corresponding control instruction for each of other N−1 switches except the source switch in the forwarding path separately. After encapsulating the generated N flow entries and N−1 control instructions into the Nth command packet, the controller sends the Nth command packet to the Nth switch of the N switches, so that the Nth switch transmits the N flow entries in the forwarding path according to the Nth control instruction in the Nth command packet.

Abstract translation: 提供流入口传送方法和通信系统。 通信系统包括控制器和N个开关。 控制器收到源交换机发送的报文消息后，确定转发转发数据的转发路径。 然后，控制器分别为转发路径中的每个N个交换机生成相应的流入口，并分别为转发路径中的源交换机之外的其他N-1个交换机生成相应的控制指令。 将生成的N个流入口和N-1个控制指令封装到第N个命令包中后，控制器向N个交换机的第N个交换机发送第N个命令数据包，从而第N个交换机按照 到第N个命令包中的第N个控制指令。
