Method and device for sending message flow

The invention provides a message flow sending method, which comprises the following steps that: access equipment transmits a first part of flow to be transmitted to a forwarding controller for inspection, and after the inspection is passed, the forwarding controller forwards the first part of transmission of the flow to be transmitted; the access device transmits the second part of the to-be-transmitted flow to the first forwarding node, and the first forwarding node forwards the second part of the to-be-transmitted flow according to the received forwarding indication information and the forwarding information of the to-be-transmitted flow. According to the technical scheme provided by the invention, the forwarding pressure of the forwarding controller can be reduced while the centralizeddeployment of the inspection strategy is realized, meanwhile, the circuitous transmission of the flow is reduced, and the flow forwarding rate is improved. 本申请提供了一种发送报文流量的方法，该方法包括：接入设备将待传输流量的第一部分传输至转发控制器进行检查，在检查通过之后，由转发控制器对待传
