Description

Network scheduling system, method and device, electronic equipment and storage medium

Technical Field

The present application relates to the field of data communications technologies, and in particular, to a network scheduling system, a method, an apparatus, an electronic device, and a storage medium.

Background

DNS (Domain NAME SYSTEM) is a service of the internet, and according to a distributed database that maps Domain names and IP (Internet Protocol ) addresses to each other, the DNS system can resolve readable Domain names input by a user terminal into digital IP addresses, and the user terminal can access the digital IP addresses.

In the prior art, the DNS system may determine an IP address corresponding to each domain name through recursive learning, and feed back the IP address to the user terminal, where each domain name may correspond to a plurality of IP addresses, and then the DNS system is required to schedule, determine one of the plurality of IP addresses, and feed back the one of the plurality of IP addresses to the user terminal, where a scheduling principle of the DNS system may be completely random scheduling, for example, if the domain name corresponds to 5 IP addresses, then the probability that each IP address is allocated to the user terminal for access is 20%. Or the DNS system can forcedly set the corresponding relation between the domain name and the IP address according to the requirement, and does not acquire the record of the domain name and the IP conversion through recursive learning.

However, in some scenarios, due to the problems of long transmission distance between the user terminal and the server, overload or failure of the website content server, failure of the website domain name authorization server, etc., problems of prolonged access of the user terminal internet content, unavailable internet content resources, prolonged recursion of the internet content domain name, failure of resolution, etc. may occur. Moreover, if the correspondence between the domain name and the IP address is forcibly set, it is likely that the specific IP is always fixed at the first position, so that the access probability is infinitely close to 100%, and overload failure of a single server is caused by excessive access. Therefore, the DNS scheduling methods may cause the user terminal to perceive degradation or even unavailability, so that the network cannot be accessed normally.

Detailed Description

In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Referring to fig. 1, an interaction diagram of a network scheduling system according to the present application is shown, where the system includes an analysis server, a cache server, and a user terminal. The method specifically comprises the following steps:

In step S11, the analysis server obtains a domain name to be analyzed according to a preset period; performing dial testing on the IP addresses corresponding to the domain name to be analyzed to obtain first dial testing data, and determining a connection quality score and a dial testing survival time value of each IP address according to the first dial testing data; determining a forced resolution address from the IP addresses corresponding to each domain name to be analyzed according to the connection quality scores; and transmitting the forced resolution address and the dial testing survival time value of the forced resolution address corresponding to each domain name to be analyzed to the cache server.

DNS is a service of the internet, and can resolve a readable domain name input by a user terminal into a digital IP address according to a distributed database that maps domain names and IP addresses to each other, and further, the user terminal can access the digital IP address. In some scenarios, the DNS system may set the correspondence between the domain name and the IP address forcibly according to the requirement, without obtaining the record of the domain name and the IP conversion through recursive learning, which may be referred to as DNS forcible resolution.

In the disclosure, an analysis server may be used to dial and measure a domain name to be analyzed, score connection quality of an IP address corresponding to the domain name to be analyzed according to a dial and measure result, and further determine a forced resolution address corresponding to the domain name to be analyzed, so as to implement DNS forced resolution of the domain name to be analyzed.

The domain name to be analyzed may be all domain names in the area, or may also be a partial domain name with higher access in the area, or may also be a domain name with higher preset importance, etc., which may be set according to requirements, and is not specifically limited.

In one implementation, the analysis server may collect the second dial testing data according to a preset period; analyzing the second dial testing data to obtain a domain name to be analyzed, wherein the domain name to be analyzed comprises a domain name and/or a preset domain name, the access times of which in the second dial testing data meet preset conditions. The second dial testing data is obtained through simulating the access operation of the user terminal.

That is, the analysis server collects the second dial testing data in each preset period by simulating the access operation of the user terminal, and further analyzes the second dial testing data to determine the domain name with the access times of the user terminal meeting the preset condition in the second dial testing data as the domain name to be analyzed. It can be understood that the access heat of the domain names to be analyzed determined in this way is higher, and the forced resolution addresses are set for the domain names to be analyzed, so that the access efficiency of the user terminal can be improved to a greater extent.

The analysis server can collect the second dial testing data through the probe, the preset period can be 5 minutes, and the preset period can also be set according to the service requirement, that is, the analysis server can dynamically simulate the access operation of the user terminal through the probe periodically, apply the N Internet applications with the largest access times in the second dial testing data, and then take the total domain names of all contents including frames, sub-elements and the like included in the Internet applications as domain names to be analyzed, wherein N is a natural number, and can be optionally taken as a value, such as a value of 100, which means that the total domain names included in the hottest 100 Internet applications in the preset period are taken as the domain names to be analyzed.

In addition, the domain name to be analyzed may further include a preset domain name, where the preset domain name may be a total number of domain names included in a specific internet application, may be a domain name of a preset web page, and the like, and may be set according to a service requirement, which is not limited in the disclosure.

In this step, after obtaining the domain name to be analyzed, the analysis server may dial-measure the IP address corresponding to the domain name to be analyzed to obtain first dial-measure data, and determine the connection quality score and dial-measure lifetime value of each IP address according to the first dial-measure data.

Fig. 2 is a schematic diagram of the principle of collection of dial testing data. Firstly, an analysis server needs to initiate a DNS request to a recursion server to acquire an IP address corresponding to a domain name to be analyzed, then, a TCP (Transmission Control Protocol ) connection with the IP address is established, further, based on the established TCP connection, a data request is sent to the IP address, an obtained data request result and response information are used as dial test data, and after the first dial test data is obtained, connection with the IP address can be ended. Where the IP address corresponds to video content, the data request may be a play request for video content, and the result of the data request may be a video stream.

In one implementation manner, the step of the analysis server initiating a DNS request to the recursive server to obtain an IP address corresponding to the domain name to be analyzed may include: the analysis server sends an analysis request aiming at the domain name to be analyzed to the recursion server; and responding to the analysis request by the recursion server, inquiring the IP address corresponding to the domain name to be analyzed, and returning the IP address corresponding to the domain name to be analyzed to the analysis server.

That is, if the local DNS recursion server does not have a domain name a/AAAA record, learning to obtain the domain name a/AAAA record by recursion query step by step; if the local DNS recursion server has the domain name A/AAAA record, all IP addresses corresponding to each domain name are directly returned to the analysis server.

In one implementation manner, the analysis server may reject IP addresses with connection quality scores lower than a preset threshold value corresponding to each domain name to be analyzed, so as to obtain candidate resolved addresses; sequencing the candidate resolved addresses corresponding to each domain name to be analyzed respectively to obtain a sequencing result; and determining the forced resolution address corresponding to each domain name to be analyzed according to the sequencing result.

The first dial-up measurement data includes, but is not limited to, DNS resolution delay, TCP connection delay, SSL connection delay, first byte delay, and element content download delay, and for web resources and video resources, the collected dial-up measurement data is different, and if the IP address corresponds to the video content, the first dial-up measurement data may further include a video playing katana rate, a loading success rate, and the like, which is not specifically limited.

That is, according to different indexes in the first dial test data, a connection quality score of each IP address may be calculated, and the connection quality score is used to evaluate the connection quality of each IP address, so that an IP address with higher connection quality may be determined from a plurality of IP addresses of the domain name to be analyzed as a forced resolution address.

In one implementation, after the analysis server dials and tests the domain name to be analyzed, first dial and test data including the quality conditions of all IP addresses under the domain name to be analyzed are obtained, and further, different IPs can be sorted according to service perception comprehensive quality according to the first dial and test data, different quality intervals are divided, special quality difference IPs are removed according to service redundancy rules, and a binding relation between the suggested domain name to be analyzed and a quality optimal IP sequence is obtained according to the random rules of the same quality interval; when the next dialing is carried out, the corresponding relation between the domain name to be analyzed and the IP is not synchronously updated if the domain name to be analyzed has no analysis record or the quality and the quality IP ordering is not changed. The IP corresponds to the service perception comprehensive quality evaluation, and recommends that the Internet application is adopted to collect the main domain name of the framework and the sub domain name of the content sub element to carry out full-quantity domain name dial testing, and comprehensively considers the network performance and the service performance.

In the present disclosure, each forced resolved address can have its corresponding dial test lifetime value, which is obtained from the recursive server, and when the current time exceeds the dial test lifetime value corresponding to a certain forced resolved address, the forced resolved address may fail.

In step S12, the cache server determines a cache lifetime value of the forced resolution address according to the dial test lifetime value and a preset optimization rule.

According to the above, each forced resolving address can have a corresponding dial testing survival time value, based on which, after obtaining the forced resolving address and the dial testing survival time value of the forced resolving address corresponding to each domain name to be resolved, the cache server can determine the cache survival time value of the forced resolving address according to a preset optimization rule. In the preset optimization rule, the main domain name and the subdomain name are consistent.

In one implementation manner, the cache server may update the forced resolution address corresponding to the domain name to be analyzed in the local cache according to the received forced resolution address corresponding to each domain name to be analyzed. That is, when the current time exceeds the cache lifetime value of the forced resolved address, then the forced resolved address may have failed and need to be updated.

For example, P represents a dial test lifetime value, X represents a cache lifetime value, and the preset optimization rule may be:

P≦100，X＝P+400；

100＜P≦200，X＝P+300；

200＜P≦300，X＝P+200；

300＜P≦400，X＝P+100；

400＜P≦600，X＝P；

P > 600, directly synchronized with 600.

The optimization updating of the dial test life time value can realize the security guarantee of the service, when the optimization server fails and is not issued to the cache server, according to the logic set by the DNS cache server, the IP resource of the DNS cache server directly accesses the original DNS recursive server after the cache life time value is expired, so that the normal access of the resource is guaranteed.

In step S13, the user terminal transmits an access request for the target domain name to the cache server.

The user terminal can interact with the user, and execute corresponding access operation in response to an operation instruction of the user, and it can be understood that the user generally inputs a target domain name, and then the user terminal sends an access request for the target domain name to the cache server, so as to obtain an IP address corresponding to the target domain name from the cache server, and then access the IP address.

In step S14, the cache server determines and returns, in response to the access request, a target mandatory resolution address corresponding to the target domain name, where the target mandatory resolution address is a mandatory resolution address with any cache duration less than the corresponding cache lifetime value.

In the present disclosure, the forced resolution address of the domain name to be analyzed and the corresponding cache lifetime value are stored in the cache server, so that when the target domain name is the domain name to be analyzed, the target forced resolution address corresponding to the target domain name can be determined and returned in response to the access request.

In one implementation, the cache server responds to the access request and sends an resolution request for the target domain name to the recursion server under the condition that the corresponding target forced resolution address does not exist in the target domain name; and responding to the resolution request by the recursion server, inquiring the IP address corresponding to the target domain name, and returning the IP address corresponding to the target domain name to the cache server.

That is, if the buffering time of the forced resolving address exceeds the corresponding buffering lifetime value, the forced resolving address may be considered to be invalid, and the buffering server may query the IP address corresponding to the target domain name from the recursive server to maintain the normal operation of the DNS system.

In step S15, the user terminal accesses the target mandatory resolution address.

That is, the user obtains the forced resolving addresses corresponding to all frames and sub-elements of the internet application, initiates an internet application access request to the forced resolving address, and enters the dynamic updating countdown of the domain name to be analyzed and the forced resolving address according to the cache lifetime value updated by forced resolving, and re-determines the forced resolving address of the domain name to be analyzed after the cache lifetime value expires.

Fig. 3 is a schematic logic diagram of the present embodiment. The analysis system operates in an analysis server, a user dials and tests Internet application through a short period of a probe, a frame of the Internet application and domain names corresponding to all element contents are returned to the analysis system, a domain name resolution request for the domain name to be analyzed is initiated, the probe queries a local DNS recursion server, the local DNS server initiates domain name recursion queries to all levels of domain name servers of the Internet, all IP addresses corresponding to the domain name to be analyzed are returned, the analysis system determines the domain name to be analyzed from the domain name recursion server, further dials and tests URLs of the IP addresses corresponding to the domain name to be analyzed, and according to dial and test quality of the IP addresses, the IP addresses with special quality differences are ordered and removed according to rules, the left IP addresses are used as forced resolution addresses to be sent to the local DNS cache server, and reasonable cache TTL (time to live value) is set for each forced resolution address according to preset optimization rules.

The following describes the present scheme by means of specific embodiments:

First, the probe dials the URL of a website by simulating the user. Then, the analysis system collects dial testing data of the website, analyzes and obtains the full-quantity domain names and URLs with contents such as the main domain name, all the webpage element sub domain names and the like. The probe initiates a website frame primary domain name and element subdomain name resolution request to a local DNS recursion server. If the local DNS recursion server does not have the domain name A/AAAA record, respectively obtaining the domain name A/AAAA record through stepwise recursion inquiry and learning; if the local DNS recursion server has a domain name A/AAAA record, all IP addresses corresponding to each domain name are directly returned to the probe. Then, the analysis system dials and measures the URL of each IP address of each domain name, obtains the quality condition of all IP addresses under the domain name after the dial and measures, sorts different IP according to quality, divides the different IP into different sections, eliminates special quality difference IP according to service redundancy rules, and obtains the binding relation between the suggested domain name and the quality good IP sequence according to the random rules of the same section; when the next dialing is carried out, the corresponding relation between the domain name and the IP is not synchronously updated if the domain name has no resolution record or the quality and the quality IP ordering is not changed.

The IP comprehensive quality evaluation method can adopt the front page loading time delay and calculate the IP comprehensive quality evaluation score, then perform quality-improving IP sequencing, and divide the IP quality interval according to the set threshold. The sub-element domain name may be the same as or different from the main domain name IP, and the index values are divided into quality spaces according to different main domain names and sub-domain names. In one implementation, the IP comprehensive quality assessment score is a top page load latency score.

The first page loading time delay testing method can be divided into single threads and multiple threads, wherein the single threads are the time spent from the analysis of the first page element to the loading of the last page element, namely the sum of the total time of all sub-items is counted; multithreading is the difference in time from parsing the first page element to completion of all page element downloads in the additional item.

The calculation formula can be expressed as:

Front page loading delay (ms) of each URL dial measurement=DNS resolution delay+TCP connection delay+SSL connection delay+front byte delay+page element downloading delay

The DNS analysis time delay is the DNS analysis time delay of a first non-jump page or a page frame, the TCP connection time delay is the TCP connection time delay of the first non-jump page, the SSL connection time delay is the SSL connection time delay of the first non-jump page, the SSL connection time delay is calculated only if the test adopts https protocol, the first byte time delay is the first byte time delay of the first non-jump page, the page element downloading time delay is the downloading time delay of each page element, and the DNS time delay of a single test record is the time delay of the first page element of the single test record.

Because the URL page depth corresponding to the main domain name of the page and the subdomain name of the element are different, the element downloading time delay is different, so the time delay threshold of the subdomain name evaluation is lower than that of the main domain name of the page; according to different deployment positions of the probes, the delay evaluation standard is correspondingly changed.

Then, sorting is carried out according to the IP comprehensive quality evaluation, and a plurality of IPs in the same quality interval are randomly sorted. The rules for different interval IP ordering, culling and synchronizing to DNS cache servers may include:

Synchronization logic, that is, the frame main domain name and the element subdomain name are kept consistent and are filtered and matched according to rules; this logic is unchanged within a certain period of time, for example, 5 minutes, and instead of a value resolved a certain time, a set of all resolution results corresponding to the same domain name within a period of time is adopted.

The IP eliminating and filtering ordering rules, namely that the number of the analyzed IP is lower than 5, IP filtering elimination is not performed, the IP is ordered from high to low according to scores in different quality intervals, and the IP in the same quality interval is randomly ordered and issued; calculating all IP home page response time delay scores of a domain name, and not performing IP filtering and eliminating when the response time delay scores are all more than or equal to 95%, and all the IP home page response time delay scores are synchronous; calculating that the top page response delay in all the IPs of a domain name has a score lower than 95 points, and for quality optimization sequencing, for example, synchronizing all the IPs in the quality interval when the number of the IPs positioned in the [95,100] points is more than or equal to 5; when the number of the IP positioned in the [95,100] points is less than 5, the top 5 are given by the quality-optimized sorting according to the IP scores; the number of IP syncs per domain name to DNS cache servers is limited to a maximum of 10.

Furthermore, the DNS cache server configures and screens the forced analysis data of the synchronous domain name and IP corresponding relation, reasonable TTL is set according to rules, and the forced analysis result is validated and refreshed. The method comprises the steps of carrying out forced analysis on IP address sequencing and TTL (transistor-transistor logic) of a main domain name and one sub domain name of a webpage in a dialing test period, carrying out dialing test on a frame and content element sub domain name score, carrying out IP sequencing and eliminating and the like of the webpage every 5 minutes in the mode, continuously and circularly carrying out the dialing test, and each period initiates an analysis request to a DNS domain name recursion server, so that a plurality of IP and comprehensive perception quality evaluation scores corresponding to access resource content are obtained in one period, and carrying out IP filtering elimination and sequencing according to the rules.

If the real user initiates the real Internet application access, the DNS cache server returns the high-quality IP and updated TTL of all domain names corresponding to the frames and the sub-element contents corresponding to the Internet according to the forced analysis result. The real user obtains the forced analysis results of all frames and sub-elements of the Internet application, initiates an Internet application access request to the high-quality IP, dynamically updates the countdown according to the correspondence between the TTL which is forced to analyze and update and the IP, and initiates a new analysis request when the Internet application access is performed after the countdown is finished.

As can be seen from the above, the present solution determines, by comparison and analysis, a connection quality score of an IP address corresponding to each domain name to be analyzed, and then uses the IP address with high quality as a forced resolution address of the domain name to be analyzed according to the connection quality score, and dynamically synchronizes the forced resolution address to the cache server.
