Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

First embodiment

As shown in fig. 1, an embodiment of the present application provides a network fault diagnosis method, which specifically includes the following steps:

step S100: the Web client responds to a first operation instruction of a user and sends a request for acquiring network operator information, an IP of a recursive domain name system and an IP of a content distribution network node to a Web server, wherein the request comprises a random sub-domain name of the Web client.

Step S102: and the Web server searches the IP of the Web client and the IP of the recursive domain name system in a database according to the random sub-domain name of the Web client.

Step S104: and the Web server searches the network operator information corresponding to the Web client according to the IP of the Web client.

Step S106: and acquiring the IP of the content distribution network node accessed by the Web client according to the IP request authoritative domain name system of the Web client.

Step S108: and the Web server sends the network operator information corresponding to the Web client, the IP of the recursive domain name system and the IP of the content distribution network node to the Web client.

Step S110: the Web client performs network fault diagnosis using the network operator information, the IP of the content distribution network node, and the IP of the recursive domain name system.

The Web client transmitting the request for acquiring the network operator information, the IP of the recursive domain name system, and the IP of the content distribution network node to the Web server in response to the first operation instruction of the user in step S100 may open the Web client on a terminal device (on a computer) for the user, and transmit the request for acquiring the network operator information, the IP of the recursive domain name system, and the IP of the content distribution network node to the Web server by clicking a network diagnostic button of the Web client. The Web client can be a browser or other webpage access application programs; the request may be an HTTP request; the random sub-domain name of the Web client in step S100 may be obtained and stored in advance, and included in the request information when the Web client sends a request.

In step S102, after receiving the request for acquiring the network operator information, the IP of the recursive Domain Name System, and the IP of the content distribution network node sent by the Web client, the Web server searches, in a database, the IP of the Web client corresponding to the random sub-Domain Name of the Web client and the IP of the recursive Domain Name System corresponding to the Web client according to the random sub-Domain Name of the Web client included in the request, where the random sub-Domain Name of the Web client, the IP of the Web client, and the IP of the recursive Domain Name System (DNS) are associated in advance and stored in the database, and the search is performed in the database based on a mapping relationship between the random sub-Domain Name of the Web client and the IP of the recursive DNS.

In step S104, the Web server searches for network operator information of the Web client according to the IP of the Web client, where the network operator information includes an operator type, such as an operator of mobile, universal, telecommunication, and the like.

In step S106, the Web server further requests an authoritative Domain Name System (DNS) to obtain an IP of a Content Delivery Network node (CDN) accessed by the Web client according to the IP of the Web client, specifically: and the Web server acquires the IP of the CND accessed by the Web client according to the internal interface of the IP request authority DNS of the Web client.

In step S108, after acquiring the IP of the recursive domain name system, the network operator information, and the IP of the content distribution network node obtained in the foregoing step, the Web server sends the IP of the recursive domain name system, the network operator information, and the IP of the content distribution network node to the Web client, and then executes step S110.

In step S110, after receiving the IP of the recursive domain name system, the network operator information, and the IP of the content distribution network node returned by the Web server, the Web client performs network fault diagnosis based on the IP of the recursive domain name system, the network operator information, and the IP of the content distribution network node.

In the designed network fault diagnosis method, through the combination of the Web server and the Web client, network fault diagnosis can be performed on any Web client device supporting access to the Web server, independent application programs do not need to be developed for various types of Web client devices, the problems that different versions need to be developed for Web client devices of different platforms when the network fault diagnosis is performed through the application programs in the traditional protocol stack, the resource investment is large are solved, and the development cost can be obviously saved; meanwhile, a user can complete network fault diagnosis only by clicking a diagnosis button on a Web client browser, the problems that the conventional protocol stack has certain technical capability requirements on the user when performing network fault diagnosis through executing codes, some dependent libraries need to be installed, and the operability and the applicability are poor are solved, and the applicability and the convenience of network fault diagnosis are improved.

In an optional implementation manner of this embodiment, the step S110 of performing, by the Web client, network fault diagnosis by using the network operator information, the IP of the content distribution network node, and the IP of the recursive domain name system may specifically include:

step S1100: the Web client sends a first resource acquisition request to a corresponding content distribution network node according to the IP of the content distribution network node, records the time consumed by the first request, and carries out network fault diagnosis according to the time consumed by the first request.

Step S1102: and the Web client sends a second resource acquisition request to the network operator according to the network operator information, records the time consumed by the second request, and diagnoses the network fault according to the time consumed by the second request.

Step S1104: and the Web client determines the network connectivity of the network operator and the recursive domain name system operator according to the network operator information and the IP of the recursive domain name system.

It should be noted that there is no execution order in the steps S1100 to S1104, and the steps may be executed simultaneously or in any order.

In step S1100, the Web client determines connectivity from the local network to the CDN node according to the first request time consumption for requesting CDN node resources, and if the first request time consumption is too long, the user may contact the CDN operator to resolve the failure due to a CDN node failure. The mode of sending the first resource obtaining request may be that the Web client sends an HTTP resource obtaining request to an interface provided by the CDN node.

In step S1102, the Web client determines connectivity from the local network to the external network according to the second request time consumption for requesting network operator resources, and if the second request time consumption is over, for example, the second request time consumption exceeds 1000ms, the surface network connectivity is poor, and the user may replace the network operator. The mode of sending the second resource acquisition request may be that the Web client sends an HTTP resource acquisition request to an interface provided by the operator's machine room server.

In step S1104, the network connectivity is also related to the local network operator and the recursive DNS operator, which may also lead to network failure if the local network operator does not coincide with the recursive DNS operator, which also leads to poor connectivity of the network.

In the embodiment designed above, the network fault diagnosis is performed through the three methods, so that the network fault diagnosis is more comprehensive.

In an optional implementation manner of this embodiment, after the Web client sends, in response to the first operation instruction of the user, a request for acquiring network operator information, an IP of the recursive domain name system, and an IP of a content distribution network node to the Web server in step S100, if the information acquisition may fail for some reason, the Web client directly goes to step S1102 to send a second resource acquisition request to the network operator according to the network operator information, records time consumed by the second request, and performs network fault diagnosis according to the time consumed by the second request.

In an optional implementation manner of this embodiment, before the step S100, in response to the first operation instruction of the user, the Web client sends a request to the Web server to acquire the network operator information, the IP of the recursive domain name system, and the IP of the content distribution network node, as shown in fig. 3, the method further includes:

step S90: and the Web client responds to a second operation instruction of the user and sends a request for acquiring the random sub-domain name to the Web server.

Step S92: the Web server acquires the IP of the Web client according to a request for acquiring the random sub-domain name sent by the Web client, generates the random sub-domain name, and stores the IP of the Web client and the random sub-domain name in a database in an associated manner.

Step S94: and the Web server returns the random sub-domain name to the Web client.

In step S90, the Web client performs, in response to the second operation of the user, sending a request to the Web server to acquire the random sub-domain name, specifically, the user accesses the Web interface through a browser of the Web client and sends an HTTP request to the Web server to acquire the random sub-domain name.

In step S92, the Web server obtains the IP of the Web client according to the HTTP request, generates a unique random subdomain name according to the IP of the Web client, associates the unique random subdomain name with the IP of the Web client, and stores the unique random subdomain name in the database, and then executes step S94 to return the unique random subdomain name to the Web client.

It should be noted that the random sub-domain name of the Web client in the present application may be regenerated each time the diagnosis is performed, or may be generated only once, then received by the Web client, stored, and then directly executed in step S100 when the network fault diagnosis is performed.

In addition, after the Web client sends the request for acquiring the random sub-domain name to the Web server in response to the second operation instruction of the user in step S90, the random sub-domain name may be failed to be acquired due to network anomaly, and at this time, sending the resource request to all operators is performed, and the resource request duration is recorded.

In an optional implementation manner of this embodiment, in step S100, before the Web client sends a request for acquiring network operator information, an IP of a recursive domain name system, and an IP of a content distribution network node to the Web server in response to a first operation instruction of a user, resolution of a domain name may occur, and in the process of resolution, the authoritative DNS may push a sub-domain name and an IP of a last-stage recursive DNS (that is, an IP of the recursive DNS mentioned above) that passes through in the process of domain name resolution to the server, as shown in fig. 4, the specific steps are as follows:

step S95: the Web client sends a domain name resolution request to the recursive DNS.

Step S96: and the recursive DNS does not find the IP of the Web server corresponding to the random sub-domain name, and the domain name resolution request is sent to the authoritative DNS.

Step S97: and the authoritative DNS records the IP of the last level of recursive DNS, pushes the IP of the last level of recursive DNS and the random sub-domain name of the Web client to the Web server, and returns the result of domain name resolution to the recursive DNS.

Step S98: the Web server associates the random sub-domain name of the Web client with the IP of the last level of recursive DNS and stores the random sub-domain name and the IP of the last level of recursive DNS in a database; the recursive DNS returns the domain name resolution result to the Web client.

Step S99: the Web client executes step S100 after receiving the domain name resolution result returned by the recursive DNS.

In step S95, the Web client sends the domain name resolution request to the recursive DNS, specifically, the browser of the Web client performs domain name resolution on the random sub-domain name first, sends the DNS request to the recursive DNS for domain name resolution, and then executes step S96.

In step S96, the recursive DNS does not find the IP of the Web server corresponding to the random sub-domain name, which means that all the recursive DNS do not find the IP of the Web server corresponding to the random sub-domain name, and the last-level DNS sends the domain name resolution request to the authoritative DNS.
