Title: METHOD AND DEVICE FOR PASSING THROUGH ISOLATION DEVICE IN MONITORING NETWORK
Abstract:
Provided is a method for a monitoring node to pass through a network isolation device in an IP monitoring system. The method comprises: using a first IP address of a monitoring node per se to initiate a tunnel connection request towards a tunnel server, so as to establish a tunnel connection with the tunnel server; after establishing the tunnel connection, obtaining a second IP address distributed by the tunnel server from the tunnel server; decapsulating a tunnel message received from the tunnel server to obtain an inner-layer IP message of which the content is monitoring signalling data, and processing the monitoring signalling data; and encapsulating the monitoring signalling data generated by the monitoring node into the inner-layer IP message, then encapsulating the inner-layer IP message into the tunnel message and sending same to the tunnel server, and the tunnel server forwarding the inner-layer IP message to a monitoring node of an outside network of a network isolation device. The present invention can effectively assist a monitoring node in a monitoring system to pass through a network isolation device, and solve various service problems caused by the isolation device.
