3, according to the tactful race that other total datas in same queries logic coupling " tactful race matched data " are corresponding.
It should be noted that, if there are any data not match tactful race in " tactful race matched data ", then directly use default policy set PGD to carry out IAD distribution; Certain tactful race matched data may match many tactful races simultaneously.
Data table related after having mated as shown in figure 17.
The handling process of step 3 is as follows:
1, as shown in figure 18, from " tactful race matching result ", take out tactful race data, inquire tactful group according to the querying condition in figure below, may find multiple (with PF1_5, PF2_5 example) simultaneously;
2, tactful group that goes other whole tactful races data corresponding is inquired about according to identity logic;
It should be noted that, if there are any tactful race data not inquire tactful group, then directly use default policy set PGD to carry out IAD distribution.
Data table related after having mated as shown in figure 19.
The handling process of step 4 is as follows:
1, every bar strategy group data simultaneous tactful group (PG1) are searched;
2, simultaneous tactful group may have multiple, now carries out IAD distribution from one (numerical value more low priority is higher) wherein choosing priority the highest.
It should be noted that, if there is no simultaneous tactful group in every bar strategy group data, then directly use default policy set PGD to carry out IAD distribution.
Data table related after having mated as shown in figure 20.
Since then, tactful relevant matches terminates, and has and only has one tactful group (tactful group or default policy set PGD are surveyed in configuration).
As shown in figure 21 and figure, the tactful group configuration strategy of certain type, but in device request information, may carry and also may not carry field corresponding to this policing type, to match this tactful group, need to meet the following conditions:
Condition one: once be configured with the strategy of certain type in tactful group, then the corresponding field of device request information, of must at least match in the type strategy just may match this tactful group;
Condition two: if policing type corresponding to certain field in tactful group of device request information does not configure any strategy, then this field can think to give tacit consent to coupling to this tactful group.
The handling process of step 5 is as follows:
As shown in figure 23, according to querying condition in Figure 23, inquire the IAD group AGG1 (because tactful group can only be configured in an IAD group, so also only an IAD group can be inquired) of strategy group PG1 configuration.Data table related after having mated as shown in figure 24.
The handling process of step 6 is as follows:
As shown in figure 25, according to querying condition in Figure 25, the online and access gateway AG 3 that load is minimum in IAD group AGG1; Data table related after having mated as shown in figure 26.
