Step 201：First load-balancing device is entered by active detecting mechanism before active-standby switch to each server state
Row routinely active detecting, and receive the second load-balancing device and send to local each server state.
In the present embodiment, the first load-balancing device is carried out routinely by active detecting mechanism to each server state
Active detecting, can be accomplished by：First load-balancing device sends healthy inspection to each server persistence
Text is observed and predicted, and judges whether each server returns health detection response message in setting duration, if it is, determining the clothes
Business device is in health status, otherwise, in malfunction.Also the regular hour can be expended due to starting active detecting mechanism, therefore
In the present embodiment, the first load-balancing device can will pass through the active detecting mechanism each to more than when in standby equipment state
Server state is detected, to save after active-standby switch the time for opening active detecting mechanism.
Step 202：It is determined that during the second load-balancing device failure, the first load-balancing device carries out active-standby switch, into
For main equipment.
