Message processing method, forwarding method, relevant device and packet loss rate measuring method

The invention discloses a message processing method, a forwarding method, a relevant device and a packet loss rate measuring method. A slave control device uses a request message at the preset form carrying the operation and control information for performing operation an control on the forwarding device to perform control message interaction with the forwarding device through a service port; the original control communication flow process requiring to bypass an active control device and then reaching the forwarding device is optimized into a direct control communication mode from the slave control device to the forwarding device; a data communication message at a special format is used; a data flow channel between the slave control device and the forwarding device is used in a multiplexing way for transmission, so that the direct transmission of the control information is realized; the control operation capability of the active control device can be released. 本发明公开了种报文的处理方法、转发方法、相关装置及丢包率测量方法，从控制装置利用具有预设格式的且携
