Cross, do not pass through, partly pass through.
Step 202, the risk of the parameter factor;
Network management device can be according to the wind of the evaluation result parameter factor of index factor running status
Danger degree.Assume that percent of pass P represents, when evaluation result is for " passing through ", P=100%;Evaluation result
During for " not passing through ", P=0%;When evaluation result is for " part is passed through ", the actual percent of pass of P=.
Risk R=1-P of index factor, R is the biggest, and the degree of risk representing this index factor is the highest.
Below with the risk indicator in the risk zones of " device element running status " in table 1 for " setting
Main/standby board cards state " index factor be " running state of single plate " as a example by, illustrate the wind of index factor
Danger degree calculates process.
Assume that network management device detects the actually detected result of running state of single plate and is: this network equipment is altogether
Having 3 pieces of veneers, wherein 2 pieces of running state of single plate are normal, and 1 piece of running state of single plate is abnormal, then pass through
Rate P=100% × 2/3=66.7%, is somebody's turn to do risk R=1-66.7% of " running state of single plate " index factor
=33.3%.
Step 203, according to the risk of index factor and the Risk rated ratio of correspondence, calculation risk index
Risk;
Manager can in advance in network management device the Risk rated ratio of the setting target factor be wj, then refer to
Mark Factor Weight collection W=[1,2 ..., f].As when f is 3, wj=1 to represent this index factor be general wind
Danger event, wj=2 to represent this index factor be important risk case, wj=3 to represent this index factor be tight
Anxious risk case, the Risk rated ratio of index factor suitably can be adjusted by user according to actually used demand
Whole.Index factor weight a if certain risk indicator includes n index factor, after normalizedj

Danger running status;R ∈ (60%, 100%] it is prime risk, represent and be in excessive risk running status.According to
The division of above-mentioned risk class, it may be determined that the risk class that each risk indicator in this equipment is corresponding.
Such as, the risk of above-mentioned " the equipment plate card state " calculated is 43.3%, should belong to light breeze danger.
Assume running status integrated risk collection RS=[the device element operation risk collection RS of this network equipment1,
Device systems operation risk collection RS2, functional protocol operation risk collection RS3, equipment runs security risk collection RS4]
Wherein: device element operation risk collection RS1=[equipment plate card risk R11, power supply risk R12,
Fan risk R13, optical module risk R14, equipment is in net duration risk R15]
In like manner:
RS2=[R21,R22,R23,R24,R25,R26];
RS3=[R31,R32,R33,R34,R35,R36];
RS4=[R41,R42,R43,R44];
May then pass through drafting radar map to assess the integrated risk collection RS of this network equipment running status.
As it is shown on figure 3, circle A1 interior zone is low-risk band, concentric circular A1 Yu A2 composition annular 1
Region is risk band, and the annular region of concentric circular A2 Yu A3 composition is excessive risk band.This network is set
The risk assessment radar map of standby running status is according to 4 Risk zone division risk area in table 1, wherein:
Risk zones 1 is device element operation risk district, and risk zones 2 is device systems operation risk district, wind
Territory, danger zone 3 is functional protocol operation risk district, and risk zones 4 is equipment safety operation risk area, each
Risk area reflects the risk sources during equipment runs in different risk zones.Then according to above-mentioned comprehensive wind
Great circle is divided into several sector regions, each by the risk that danger collects the risk indicator in RS corresponding
In the sector region that risk indicator is corresponding, draw the risk of this risk indicator, thus reflect whole net
