Whether STU mainly is responsible for detection system and satisfies from the recovery condition, carries out system from recovering according to the policy library corresponding strategy;
Particularly, STU is used for the running status of the predetermined policy object of system is detected, reach the policy condition of storing among the SB relevant (promptly from the recovery condition) if detect the running status of described policy object, then described system is recovered according to the corresponding recovery policy of the policy condition relevant of storing among the SB with described policy object with described policy object.
SB is used for storage from recovery policy information; The interface in visit recovery policy storehouse is provided, and described recovery policy information comprises: policy object, policy condition and the recovery policy relevant with this policy object.
Wherein, described policy object can be internal memory, and the described policy condition relevant with this policy object can exhaust or full memory exhausts for crucial internal memory, and the recovery policy corresponding with this policy condition is system is resetted;
For example, the utilization rate of crucial internal memory or the utilization rate of full memory reach 80%, and the utilization rate of crucial internal memory is preferably average service rate in the given time, or the utilization rate of full memory is preferably average service rate in the given time.
Described policy object also can be processor, and the described policy condition relevant with this policy object can surpass at the fixed time at full capacity for processor, and the recovery policy corresponding with this policy condition is for to reset to system;
For example, the utilance of processor reaches 90% or 100%, and the utilance of processor is preferably average service rate in the given time.
Described policy object also can be network security, and the described policy condition relevant with this policy object can be subjected to network storm for system, and the recovery policy corresponding with this policy condition is for being provided with Virtual Local Area Network;
For example, the quantity of broadcast packet reaches 60% of overall budget number, and the system that then is considered as is subjected to network storm.
Described policy object also can be network security, and the described policy condition relevant with this policy object can can't normally move for system is subjected to network attack, and the recovery policy corresponding with this policy condition resets to system.
For example, when the quantity that system receives the message bag that non-native system accepts reaches predetermined value, for example surpass 50% o'clock of overall budget number, the system that then is considered as is subjected to network attack and can't normally moves.
