Specifically, the network A, B is deployed with parallel network isolation devices A, B, C; the network B, C is deployed with parallel network isolation devices D, E, F; the network C, D is deployed with parallel network isolation devices G, H, I; wherein, there are independent network links between the network isolation devices A, D, B, E, B, F, C, F, D, G, E, G, F, H and F, I;
the functions and responsibilities of the network probes I, II and III are respectively as follows:

if the network probes II and III are reported successfully and the reporting of the network probe I fails, the network isolation device A, B, C may both fail, and the probability of the network device C failing is the greatest;
if the network probe III is successfully reported and both the I and the II fail, the network isolation device A, B, C, D, E, F may have a fault, the network isolation device D, E, F has a high possibility, and the network isolation device F has a maximum possibility;
if the network probes I, II, and III all report failure, all the network isolation devices may fail, the network isolation device G, H, I has a high possibility, and the network isolation device I has the highest possibility.
When the performance of the network isolation equipment is monitored, PING is used for detecting PING delay between two network isolation equipment in a corresponding link, an SNMP protocol is used for detecting the network port rate of the link, the load condition of the link bandwidth is checked through the actual rate/the configuration rate, and when the link bandwidth exceeds the threshold value, an alarm is given in time.
