Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of an embodiment of an IP address allocation method according to the present invention, as shown in fig. 1:
And 102, extracting the behavior characteristics of the IP address used by the user from the IP address use historical data.
And 103, classifying the users according to the behavior characteristics, and determining the user group category to which the users belong.
And step 104, determining the user scale of the user group category, and determining the IP address scale corresponding to the user group category according to the user scale.
And 105, generating an IP address pre-allocation strategy according to the user group category and the IP address scale, and allocating the IP address based on the IP address pre-allocation strategy. Generating the IP address pre-allocation policy includes: generating at least one IP address block corresponding to the user group category, and the like.
In one embodiment, a variety of algorithms may be employed to classify users according to behavioral characteristics. For example, the users are classified according to the behavior characteristics, and a K-means clustering algorithm is adopted to build a model. The K-means algorithm is that a certain distance between a data point and a prototype is used as an optimized objective function, and an adjustment rule of iterative operation is obtained by using a function extremum solving method. The K-means algorithm can use Euclidean distance as similarity measure to solve the optimal classification of a corresponding initial clustering center vector V, so that the evaluation index J is minimum. The behavior characteristics of the user using the IP address comprise: the time of requesting the IP address, the time of surfing the internet, the time length of surfing the internet, the frequency of surfing the internet and the like. The existing modeling methods based on the K-means clustering algorithm can be adopted to establish a model, and users can be classified according to behavior characteristics.
Receiving an address allocation request sent by a user, determining a user group category to which the user belongs, acquiring an IP address in an idle state from an IP address block corresponding to the user group category, configuring the IP address to the user, and setting the IP address to be in a use state after the configuration is successful. Category labels corresponding to the user group categories may be set, and users belonging to the user group categories and IP address blocks corresponding to the user group categories may be identified using the category labels. When an address allocation request sent by a user is received, a category label corresponding to the user is determined, an IP address block corresponding to the user group category is determined based on the category label, and an IP address in an idle state is obtained from the IP address block and is configured to the user.
And determining the IP address which is most frequently used and is in an idle state in the IP address block, and configuring the IP address to the user. And determining whether the IP address block has the IP address used by the user once, and if so, preferentially allocating the IP address to the user, namely preferentially allocating the IP address used once in the idle state to the IP address in the idle state with the highest use frequency in the IP address block.
Fig. 2 is a schematic flowchart of classifying users in an embodiment of the IP address assignment method according to the present invention, as shown in fig. 2:
Background capture is carried out on data of historical use conditions of the IP address of the user, and the data can be obtained by inquiring a log file. The IP address usage history data may have a plurality of data, such as the time when the user uses the IP address the earliest day, the time when the user surfs the internet every day, the total duration of the user using the IP address a week, the number of internet surfing days of the user in a peak period (for example, 8 o 'clock to 10 o' clock at night) in a week, the number of internet surfing days of the user in a peak period in a month, and the like.
For example, the user database is a hive database, data meeting the conditions is screened by MySQL language (for example, the user on a specific date surfs the internet, and the limited conditions are the date of the day) and is logged in the database and an inquiry statement is input: SELECT FROM user IP info word date '2017-09-09', and using the screened data as the required IP address usage history data.
And (3) carrying out data cleaning and data arrangement on the historical data used by the IP address, and carrying out data preprocessing work, wherein the final data format is as follows: user equipment ID, region number, daily IP address demand period, holiday and festival IP address use condition, and weekday and weekend IP address use condition. And after the IP address use historical data is subjected to data cleaning and sorting, behavior characteristic data of the IP address used by the user is generated.
And step 204, constructing a model by using a K-means clustering algorithm.
And constructing a model by using a K-means clustering algorithm, classifying the user clusters according to the behavior characteristics of the user using the IP address, and setting labels for the users with different IP address requirements. For example, based on the behavior characteristics, the centroid number is adjusted according to the number of the virtualized broadband remote access servers, the input data is aggregated into different clusters according to the similarity of the characteristics, i.e., the classified user categories, and the sk-leann library in Python may be used. For example, the results of the user classification are shown in table 1 below:
| user ID | Attribution of user group categories |
| 0001 | A |
| 0002 | B |
| 0003 | A |
| 0004 | C |
TABLE 1 results Table for user classifications
In Table 1, the category of A is characterized in that the Internet is accessed by using an IP address at a high frequency of 16: 00-21: 00 every day; the class characteristics of B are: surfing the Internet by using an IP address at a high frequency of 20: 00-23: 00 every day; the class C is characterized in that the IP address is used for surfing the Internet at a high frequency of 00: 00-02: 00 every day.
In one embodiment, the size of the block of IP addresses is sized according to the size of each user population category. For example: the users belonging to the user group category have x persons in total, the number of the IP addresses contained in the IP address block can be set to be alpha x, and alpha is a system, so that the redundancy of about 10 percent can be increased on the number of the users belonging to each user group category to supply for elastic processing of practical situations. And formulating a preliminary IP address pre-allocation strategy according to the classification condition of the user group categories and the scale of the IP address blocks.
And transmitting the IP address allocation strategy to the V-Bras system for configuration. Several consecutive blocks of IP addresses can be placed into a V-Bras, which is responsible for managing these several blocks of IP addresses uniformly. When a user puts forward an IP address requirement to V-Bras, the V-Bras finds a corresponding IP address block set according to a user label and configures an address in an IP address block with the highest current utilization rate, and on the basis, if the IP address used by the user in history is in an idle state at present, the address is preferentially configured to the IP address used by the user. For example, user M requests an IP address, determines an IP address block corresponding to the user category of M, and selects a first unused IP address from the IP address block to allocate to user M.
Fig. 3 is a schematic flowchart of allocating an IP address to a user in an embodiment of an IP address allocation method according to the present invention, as shown in fig. 3:
And 303, if so, selecting an idle IP address block from the plurality of IP address blocks as a standby IP address block, and acquiring the IP address in an idle state from the standby IP address block and configuring the IP address to a user. For example, if it is detected that the usage of the current block of IP addresses has reached the trigger threshold, an idle block of IP addresses belonging to the same class label is prepared as a spare block.
Fig. 4 is a schematic flowchart of recovering an IP address in an embodiment of an IP address allocation method according to the present invention, as shown in fig. 4:
For example, the address of the last use state of a certain IP address block is converted into an idle state, the address in the certain IP address block is completely idle, whether the IP address block is a standby IP address block is determined, and if the IP address block is the standby IP address block, no processing is performed; if not, the IP addresses in the segment of IP address block are uniformly recovered for later distribution. The use condition of the IP address blocks in the management range can be received through the monitoring interface in real time, and statistics can be carried out.
And if the number of times that the address requirement of the user is determined to be not matched with the configured IP address reaches the preset distribution adjustment triggering threshold value in the preset time period, reclassifying the user and determining the user group category to which the user belongs. When the IP address requirement of a certain user is inconsistent with the IP address allocated based on the pre-allocation strategy for a plurality of times within a period of time, the pre-allocation strategy adjustment process is triggered. Recording the user with the IP address requirement not in accordance with the IP address distributed based on the pre-distribution strategy, setting a distribution adjustment triggering threshold, placing the user with the number of times of the occurrence of the non-in accordance with the distribution adjustment triggering threshold into a redistribution set, and classifying and dividing the users in the redistribution set again.
After a period of time, the internet access habits of the users corresponding to some IP address blocks are changed for some subjective or objective reasons and reach a certain proportion (for example, 40% of the users do not conform to the original characteristic habits), the users are classified again, the user group categories to which the users belong are determined, the scale of each pre-allocated IP address block is re-formulated, the adjusted pre-allocation strategy is generated, and the IP addresses are allocated.
The IP address allocation method provided by the embodiment can intelligently and adaptively adjust the scale of the user block and reduce the time consumption of user block resource adjustment, and the adopted number and scale pre-allocation granularity of the user block are small, so that the method is strong in operability and high in practicability; the allocation of the IP address can be dynamically adjusted, so that the management is convenient and the controllability is strong; the method can process the request in a centralized way, has strong self-adaption of IP address block resource reallocation, high utilization rate and short reallocation period, and ensures that the pre-allocation of the IPv4 address is more reasonable.
