Content Delivery Network (CDN, Content Delivery Network) is a layer of intelligent virtual network built on the basis of the existing Internet. It redirects user requests to the CDN node closest to the user, so that users can obtain the required content nearby. , to solve the situation of Internet network congestion, and improve the response speed of users visiting websites.

With the advent of the mobile Internet era, the business model of "platform + application (the application refers to software that needs to be provided to users with the help of the platform, such as Android applications, website applications, and Apple applications)" has accelerated the emergence and update of applications. . Since many applications do not exist in the data centers of telecom operators in the same province, when mobile Internet users access applications across different provinces and networks of different telecom operators, the access speed decreases and the user experience decreases. .

Therefore, building a CDN in the mobile Internet is a need for application development and an effective means to improve user application access speed. Usually, the basic strategy for building CDN nodes is to set up CDN nodes for requested content in network areas with many user requests. However, existing CDN service providers cannot know where the mobile Internet users who access the application belong, and thus cannot accurately locate the content in areas with many user requests. The user's home site sets a CDN node for the application accessed by the user.

With the increasing cooperation between CDN service providers and telecom operators, it will become a trend for telecom operators and CDN service providers to jointly build a CDN network in the mobile Internet in the future. If CDN nodes can be properly set up, it will help CDN service providers to serve users Providing a faster network access experience can also improve the application value of operators, so how to reasonably set up CDN nodes while meeting the needs of all parties is an urgent problem to be solved.

It should be noted that, in practical applications, when setting up CDN nodes at users' home locations, in addition to considering the above mentioned CDN node setting policies, the attribution of users' access to applications, the user's attribution locations, and the value of applications at each user's attribution locations, etc. In addition to factors, other factors can also be considered, such as CDN load and so on.

The above embodiment will be further described below with a specific application example.

Step 1, extract the basic data from the detailed list of mobile user Internet traffic; the basic data includes: terminal IP, access IP, Internet start time and Internet end time, Internet duration, Internet traffic, extracted once a day; in the form of files Store the extracted basic data in the database for analyzing the access IP;

Since nearly 1GB of basic data is generated every day, if you need to count the basic data of each quarter, you need to store 1GB*31*3=91GB of data. Faced with such a large amount of data, this step can choose the open source distributed database HBase Store basic data;

Step 2, import the extracted basic data from the open source distributed database HBase to the Oracle database (the import cycle is 1 day, using sqoop to import), and the Oracle database stores the data imported from Hbase in a partitioned manner by day;

Step 3: Perform data cleaning on the IP addresses from the network, generate the corresponding relationship between the IP address and the attribution, and the corresponding relationship between the IP address and the network domain name, and import the relationship into Hbase; taking the generation of the corresponding relationship between the IP address and the attribution as an example, The IP data obtained from the network includes Harbin Institute of Technology in the address, but does not belong to the province. At this time, it is necessary to clean the IP data, filter those data that do not meet the requirements, and supplement the province corresponding to the IP address segment of Heilongjiang Province;

Obtain the network domain name, attribution and user attribution corresponding to the access IP in the basic data stored in Hbase according to the corresponding relationship;

Step 4, in the Hbase database, calculate the value of each application in each user's attribution;

Step 5, in the Hbase database, according to the CDN node setting policy, the location of the application and the value of the application at the location of each user, determine whether to set a CDN node for the application at each user location.

This application example provides two scenarios for determining whether to set up a CDN node for an application in each user's home location based on the CDN node setting strategy, the location of the application, and the value of the application in each user's home location:

In the first application scenario, starting from the access source (mobile user's home), select the most valuable application generated in the user's home, if the home of the high-value application is different from the user's home, then the application Set up a CDN node at the user's home location:

Select the place where the user belongs, such as Beijing Unicom;

Sort the value of each application in Beijing Unicom, and select the applications whose value is greater than or equal to the first threshold, as shown in Table 1;

Table 1

Judging whether the selected application belongs to Beijing Unicom, if not, sending an instruction to set up a CDN node for storing the application in Beijing Unicom. For example, if the application with the highest value in Beijing Unicom, if the target IP is 61.135.167.xxx, the corresponding attribution is Guangdong Telecom, which is different from Beijing Unicom. Therefore, an instruction is issued to set up a CDN node for storing the application in Beijing Unicom.

In the second application scenario, starting from the target application, select the application with the largest total value, and select the user's attribution that contributes the most to the total value of the application. If the user's attribution is different from the application's attribution, it is determined as the The application sets up a CDN node at the home of the user with a large contribution:

For each application, the value of the application in each user's home location is summed to obtain the total application value of the application;

Sort the applications according to the total application value, as shown in Table 2;

ranking target IP Target IP location value 1 61.135.167.xxx Guangdong Unicom 0.60 2 61.135.167.xxx Zhejiang Unicom 0.59 3 111.206.169.xxx Hebei Unicom 0.57 4 60.28.13.xxx Shanghai Unicom 0.50 5 123.123.123.xxx Shandong Unicom 0.40 … ... ... ... 28 60.135.157.xxx Sichuan Unicom 0.27 29 60.220.96.xxx Henan Unicom 0.23 30 125.30.245.xxx Heilongjiang 0.10

Table 2

If the total application value is greater than or equal to the second threshold, calculate the ratio of the value generated by accessing the application through a user's attribution different from the application's attribution to the total application value, if the ratio is greater than or equal to the third threshold, then Send out an instruction to set up a CDN node for the user's attribution of the application. For example, the application that ranks first in total application value has multiple user attributions: Zhejiang Unicom and Fujian Unicom; the calculations are based on multiple user attributions such as Zhejiang Unicom and Fujian Unicom. The proportion of the application value generated by accessing the application locally to the total application value, if the proportion of the application value generated by accessing the application through Zhejiang Unicom to the total application value is greater than or equal to the third threshold, a An instruction to set up a CDN node; if the ratio of the application value generated by accessing the application through Fujian Unicom to the total application value is less than the third threshold, then no instruction to set up a CDN node for the application in Zhejiang Unicom is issued;

Step 6, tabulate the access network domain name, access IP, source IP, access application attribution, user attribution, and whether to issue an instruction to add a CDN node.

When building a CDN network, the table can be conveniently retrieved from the Hbase database for reference.

7. system as claimed in claim 6, is characterized in that, described in be applied in each user ascription area and be worth determination module, for in the Corpus--based Method cycle, the recorded information of user's access application of each user ascription area, is applied in the value of each user ascription area described, comprises described in determining respectively:

To each user ascription area:

Based on the recorded information of this user ascription area user access application, obtain in described measurement period, each Subscriber Unit time accesses the average surfing flow that described application produces;

By described user attaching, each Subscriber Unit time accesses average surfing flow that described application produces and the average surfing flow of described user attaching each Subscriber Unit time of ground and is divided by and obtains each Subscriber Unit time normalized and access the average surfing flow that described application produces on the ground;

Obtain in described measurement period, each user average income APRU that operator obtains from each user applied described in this user attaching accessing;

APRU operator obtained from each user applied described in described user attaching accessing and operator are divided by from the APRU that each user of described user ascription area obtains and obtain the APRU that normalized operator obtains from each user applied described in described user attaching accessing;

The average surfing flow of being accessed described application generation described each Subscriber Unit time normalized is multiplied by flow weight, add from the APRU that each user applied described in described user attaching accessing obtains, normalized operator is multiplied by that ARPU weight obtains and, as the described value being applied in this user ascription area.

8. system as claimed in claim 7, it is characterized in that, described be applied in each user ascription area be worth determination module, for the recorded information based on this user ascription area user access application, obtain in described measurement period, each Subscriber Unit time accesses the average surfing flow that described application produces, and comprising:

From the detailed list of user's surfing flow, obtain basic data, described basic data comprises: terminal IP, access IP, online time started and online end time, surf the Net lasting duration, surfing flow;

The domain names of the application correspondence that user accesses is determined according to access IP;

According to online time started, online end time and surfing flow, add up the surfing flow M accessing domain names generation corresponding to described application in measurement period;

Continue duration according to online time started, online end time and online, add up and access the described online duration T applying corresponding domain names and produce in described measurement period;

According to online time started, online end time and terminal IP, add up the number N of the terminal IP accessing domain names corresponding to described application in described measurement period;

Is accessed the average surfing flow that described application produces M/ (T*N) each Subscriber Unit time on described measurement period.

9. the system according to any one of claim 6 ~ 8, it is characterized in that, described CDN node arranges module, for according to CDN node Provisioning Policy, and the ownership place of application and the described value being applied in each user ascription area described, determine whether, for described each user ascription area that is applied in arranges CDN node, to comprise:

Select user ascription area;

If the value being applied in the user ascription area selected is more than or equal to first threshold, judge that whether the ownership place of this application is identical with the user ascription area of described selection, if not identical, then send as this user ascription area being applied in selection arranges the instruction of CDN node.

10. the system according to any one of claim 6 ~ 8, it is characterized in that, described CDN node arranges module, for according to CDN node Provisioning Policy, and the ownership place of application and the described value being applied in each user ascription area described, determine whether, for described each user ascription area that is applied in arranges CDN node, to comprise:

To each application, this is applied in the value summation of each user ascription area, obtains total using value of this application;

If when total using value is more than or equal to Second Threshold, calculate the ratio that the value produced by this application of user attaching accessing not identical with this application ownership place accounts for described total using value, as ratio is more than or equal to the 3rd threshold value, then send as this is applied in the instruction that this user ascription area arranges CDN node.
