Aiming at the problem of non-standard protocol monitoring platform interconnection, a platform interconnection scheme based on SIP protocol is proposed. A system management platform is built through this scheme to realize platform access and monitoring. Resource Sharing. First, the registration connection of the two monitoring platforms is performed by means of a proxy, and then the session channel and the media stream transmission channel are established. The session channel is used to establish a session between the platforms and transmit system control commands. The SIP protocol is used to establish the session and control the command forwarding. The media stream channel is used to transmit video and audio data, and the UDP protocol is used for data flow. Forwarding, thereby enabling monitoring resource sharing between the two platforms.
