In order to improve the performance and accuracy rate of rule entry hit-count statistics, and reduce to the greatest extent to processor resource
It occupies, the embodiment of the present application proposes a kind of rule based on processor local storage space and processor external memory space
List item hit-count statistical method.As shown in Figure 1, FPGA local storage space RAM, FPGA external storage are empty by taking FPGA as an example
Between DDR, be based on FPGA local storage space RAM and external memory space DDR, the hit-count of statistical rules list item passes through
The mark and hit-count of storage rule list item in local storage space RAM read current round local storage space RAM
The mark and hit-count of middle rule entry determine the hit-count increment of current round rule entry, from external storage sky
Between the historical hit number of rule entry is read in DDR, hit-count increment and historical hit number are added up, rule list is obtained
The current hit-count of item, so using local storage space RAM as the transfer of rule entry hit-count, it can be ensured that rule
The then correctness of the hit-count statistics of list item.
In order to further be illustrated to technical solution provided by the embodiments of the present application, the following example is provided:
As shown in Fig. 2, being a kind of implementing procedure of rule entry hit-count statistical method provided by the embodiments of the present application
Schematic diagram, this method can specifically include following steps:
S201 determines the rule entry for meeting preset requirement, and counts the hit-count of the rule entry；
Currently for route exchange device or Network Security Device, usually there is a large amount of rule entry, this rule-like
List item is for carrying out message forwarding, packet filtering, session management etc., and the order of magnitude of this kind of rule entry is usually million, thousand
Ten thousand, the orders of magnitude such as hundred million.Since rule entry is large number of, and local storage space is limited, therefore meeting selected part rule entry, i.e.,
Determine the rule entry for meeting preset requirement.
In the embodiment of the present application, the rule entry for meeting preset requirement is to determine that message is ordered within a preset period of time
In rule entry.Such as it can determine the rule entry that in nearest one month or message is hit in a nearest week.
In addition to this, for numerous rule entry, user can specify certain rule entry, determine the rule that user specifies
Then list item, or determine the rule entry created in a period of time recently, it can be arranged according to actual needs, the embodiment of the present application
This is not construed as limiting.
For the rule entry of above-mentioned determination, the hit-count of statistical rules list item, a rule entry message of every hit,
Hit-count adds 1.Such as rule entry A, rule entry B, rule entry C ..., difference statistical rules list item A, rule
List item B, the respective hit-count of rule entry C ....
S202 stores the mark of the rule entry and hit-count into local storage space；
For any of the above-described rule entry, its hit-count is counted, and real-time storage is into local storage space, such as deposit
Storage is into local storage space RAM.
In addition, it is also necessary to store the mark of rule entry into local storage space, using local storage space as rule
The then transfer of list item hit-count statistics.The mark of rule entry can be with ID, title etc., by the mark and hit of rule entry
Number is stored into local storage space in combination, as shown in table 1 below:
| Rule entry mark | Rule entry hit-count |
| A | 80 |
| B | 60 |
| C | 50 |
Table 1
By above-mentioned table 1 it is found that real-time storage is to being locally stored sky after the rule entry hit-count of statistics updates
Between in, to complete update to rule of correspondence list item hit-count in local storage space.
S203, reads the mark and hit-count of rule entry described in current round local storage space, and determination is worked as
The hit-count increment of rule entry described in preceding round；
For the mark and hit-count of rule entry in local storage space, poll reads in local storage space and advises
The then mark and hit-count of list item.For current round, the mark and life of rule entry in local storage space are read
Middle number can determine the hit-count increment of current round rule entry.
The hit-count increment for wherein determining current round rule entry specifically may is that according to the reading of current round
In local storage space in the hit-count of rule entry and the last round of time local storage space read rule entry life
Middle number determines that the hit-count increment of rule entry described in current round, hit-count increment are the increased number of hit-count
Amount.Such as rule entry A, rule entry B, the respective life of rule entry C ... in the last round of local storage space read
Middle number is 80,60,50 ... respectively, rule entry A, rule entry B, rule in the local storage space that current round is read
The respective hit-count of list item C ... is 90,60,70 respectively, then in the local storage space that can determine current round reading
The respective hit-count increment of rule entry A, rule entry B, rule entry C ... is 10,0,20 ... respectively.
S204 reads the historical hit of the rule entry from external memory space according to the mark of the rule entry
Number；
For the mark of the above-mentioned rule entry read from local storage space, can be read according to it from external memory space
Take the historical hit number of rule entry.For example, A, B, C ... are identified according to rule entry, it can be from external memory space
Rule entry A, rule entry B, the corresponding historical hit number of rule entry C ... are read respectively.
Wherein, before the historical hit number that external memory space reads rule entry, judging current round rule
Whether the hit-count increment of list item is greater than preset threshold, if the hit-count increment of current round rule entry is greater than default threshold
Value reads the historical hit number of rule entry from external memory space according to the mark of rule entry, if current round rule
The hit-count increment of list item is not more than preset threshold, then need not be read according to the mark of rule entry from external memory space
The historical hit number of rule entry.
For example, for rule entry A, rule entry B, rule entry C ..., respective hit-count increment is 10 respectively,
0,20 ..., preset threshold can be 0, learn that respectively hit-count increment is greater than by rule entry A, rule entry C by judgement
Preset threshold, according to mark A, C of rule entry, from external memory space reads rule entry A, rule entry C is respectively corresponded to
Historical hit number, rule entry B hit-count increment be not more than preset threshold, then need not according to rule entry identify B, from
The historical hit number of external memory space reading rule entry B.
The hit-count increment and the historical hit number are added up, obtain the current of the rule entry by S205
Hit-count.
For being read in the hit-count increment and step S204 of the above-mentioned steps S203 current round rule entry determined
The historical hit number of the rule entry taken, the two is added up, and the current hit of current round rule entry can be calculated
Number.
For the current hit-count of current round rule entry obtained above, can be stored to external storage sky
Between, current round is completed to the statistics of rule entry hit-count, in order to which next one reads rule from external memory space
The historical hit number of list item.
By the above-mentioned description to technical solution provided by the embodiments of the present application, statistics meets the rule entry of preset requirement
Hit-count it is local to be read by the mark and hit-count in local storage space storage rule list item for current round
The mark and hit-count of rule entry in memory space, determine the hit-count increment of current round rule entry, from outer
