Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present application.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.

It should be noted that embodiments of the present application or technical features of embodiments may be combined without conflict.

In the related art, an operator provides server list rules including: (1) Under the condition that the main domain name is recorded, the Internet of things equipment can access all sub domain names under the main domain name; (2) any domain name not yet filed cannot be accessed.

For example, after the main domain name domain.com is filed, a.domain.com, b.domain.com may be accessed; but cannot access a.domain1.Com. Thus, if the sub domain name a.domain.com is bound to the server a, and the sub domain name a.domain1.com is bound to the server B, the internet of things device can normally access the server a, and cannot normally access the server B.

Therefore, the problem that if the domain name and the IP address corresponding to the newly added server are not in the recorded server list, the domain name and the IP address cannot be normally accessed by the Internet of things equipment is solved; the application provides an IP address access method, an Internet of things platform, equipment, a system and electronic equipment; further, by collecting the IP address with failed access, a sub domain name corresponding to the failed IP address may be added according to the main domain name, so that the IP address may be accessed, thereby improving the situation that the service provided by the internet of things platform cannot be implemented.

The above related art solutions have drawbacks, which are results obtained by the inventor after practice and careful study, and therefore, the discovery process of the above problems and the solutions proposed by the embodiments of the present application hereinafter for the above problems should be all contributions of the inventor to the present application in the process of the present application.

Referring to fig. 1, a flowchart of an IP address access method according to an embodiment of the present application is shown. The IP address access method can be applied to an Internet of things platform, and the Internet of things platform stores a main domain name.

It should be noted that the primary domain name is already at the carrier. If a certain physical network device accesses the master domain name, it can access normally.

The physical network platform may be, for example, a single server that can substantially communicate with the internet of things device, a server cluster formed by a plurality of servers, a cloud computing center, or the like. The internet of things device, that is, the device for communicating by using the internet of things card, may include, for example, a smart television, an automatic vending machine, and the like.

As shown in fig. 1, the IP address access method includes the following steps 101 to 103.

Step 101, if a target IP address with access failure is received, generating a new sub domain name according to the main domain name under the condition that the target IP address is determined to be a new IP address;

in some application scenarios, the physical network device may send the IP address with the failed access to the internet of things platform. In these application scenarios, the IP address may not be recorded, or the access failure of the IP address may be caused by a network failure, a server failure corresponding to the IP address, or the like.

When the physical network platform receives the target IP address with failed access, it can first determine whether it is a new IP address to determine whether the target IP address can access the already-registered primary domain name.

In some application scenarios, the physical network platform may, for example, build an IP address library in which all IP addresses currently accessible may be stored. In this way, if the target IP address is not found in the IP address library, the target IP address is considered to be not recorded; if the target IP address is queried in the IP address library, it may be considered that the reason that the physical network device cannot access is not that the target IP address is not recorded, and the internet of things device may be instructed to find other reasons.

Further, if it is determined that the target IP address is a new IP address, a new sub-domain name may be generated according to the main domain name. In some application scenarios, the physical network platform may set a unique corresponding number for each sub-domain name, for example, and then when generating a new sub-domain name, the physical network platform may generate according to the number. For example, the main domain name is domain.com and the former sub domain name is a5.domain.com, then a new sub domain name of a6.domain.com can be currently generated. In other application scenarios, the physical network platform may also randomly generate a new sub-domain name, for example, which the present application is not limited to.

Step 102, storing the association relationship among the main domain name, the new sub domain name and the target IP address;

in some application scenarios, after the sub domain name is generated, the physical network platform may associate the main domain name, the new sub domain name and the target IP address to form a mapping relationship between the three. In this way, one primary domain name may be associated with multiple sub-domain names, each of which may be associated with one IP address, such that a single primary domain name supports access to multiple IP addresses.

Step 103, if a sub domain name acquisition request sent by any one of the internet of things devices is received, the new sub domain name is sent to the internet of things device, so that the internet of things device can access the target IP address through the new sub domain name.

In some application scenarios, after receiving a subdomain name acquisition request sent by any one of the internet of things devices, the physical network platform may send only the new subdomain name or send all subdomains including the new subdomain name. In this way, the internet of things device can access the failed target IP address according to the acquired new subdomain name.

In the related art, as the service increases or the current server resources are not enough, a new server needs to be added to the internet of things platform, so that the domain name and the IP address corresponding to the new server cannot be normally accessed by the physical network device because the domain name and the IP address corresponding to the new server are not recorded.

In this embodiment, in the case that the target IP address is determined to be a new IP address, a new sub domain name may be added to the main domain name that has already been recorded. Therefore, the new subdomain name can be dynamically added without being limited by the domain name or whether the IP address is recorded, and the aim that the Internet of things equipment can normally access the newly added server is achieved.

In some optional implementations, in the case that the target IP address is determined to be the new IP address in step 101, generating a new sub-domain name according to the main domain name includes: if the target IP address is not found in the association relation stored currently, determining that the target IP address is a new IP address; and generating the new sub-domain name based on the plurality of history sub-domain names associated with the main domain name.

In some application scenarios, the internet of things platform can store the association relationship among the main domain name, the sub-domain name and the IP address, so that when the target IP address is received, the sub-domain name corresponding to the target IP address can be searched according to the association relationship, and the current target IP address is determined to be a new IP address under the condition that the sub-domain name is not searched.

The physical network platform may then also generate a new sub-domain name based on the associated plurality of historical sub-domain names without repeating the sub-domain name.

In the implementation manner, the accuracy and convenience for determining the new IP address and generating the new sub domain name can be improved by utilizing the association relationship among the main domain name, the sub domain name and the IP address.

In some optional implementations, if the target IP address of the access failure is received in the step 101, before generating a new subdomain name according to the main domain name if the target IP address is determined to be a new IP address, the method further includes the following steps:

step 001, if a service domain name list acquisition request is received, sending a service domain name list; the service domain name list comprises subdomain names which are required to be accessed for realizing the service;

the internet of things platform may provide a variety of services, which may include, for example, push services, forward services, and the like. For each service, the internet of things platform may set one or more subdomains that must be accessed to implement the service, which may be considered as the service domain names described above.

In some application scenarios, the physical network platform may make a service domain name list, where the service domain name list may include a plurality of service information and corresponding service domain names. Thus, after receiving the service domain name list acquisition request, the service domain name list may be transmitted to the physical network device.

Step 002, sending a return instruction to the internet of things device; the return instruction is used for indicating: resolving an IP address corresponding to each service domain name in the service domain name list; and returning the IP address as the target IP address in the case of failure in accessing the IP address.

After the physical network device obtains the service domain name list, each service domain name in the service domain name list can be accessed. In some application scenarios, for example, the access may be sequential or random, without limitation.

In the process of accessing the service domain name, the internet of things device needs to firstly analyze the IP address corresponding to the service domain name. In some application scenarios, the physical network device may send an resolution request to a domain name resolution server, for example, and if the resolution server returns response information indicating that resolution fails, the resolution server may consider that the current service domain name is not available, and may continue to resolve the next service domain name. If the domain name resolution server returns the resolved IP address, access can be performed. In the process of accessing the resolved IP address, if the access fails, the IP address can be collected and returned to the Internet of things platform. In these application scenarios, for example, failure to receive response information, access timeout, or the like may be regarded as access failure.

In this implementation manner, the internet of things platform may instruct the physical network device to collect the IP address with failed access, so as to be able to newly add a new sub domain name corresponding to the IP address. In this way, when the service domain name list acquisition request sent by the internet of things device is received again, the new sub domain name can be sent, so that the physical network device can normally access the IP address which is failed to access before, and corresponding service is realized.

In some optional implementations, after sending a return instruction to the internet of things device, the method further includes: sending a service domain name keep-alive instruction to the Internet of things equipment; the service domain name keep-alive instruction is used for indicating: the parsed IP address is accessed multiple times to place the IP address in an accessible state.

The accessible state can be regarded as a state that the internet of things equipment is in continuous communication with the server corresponding to the IP address, so that the physical network equipment can be normally accessed when the physical network equipment needs to be accessed.

In some application scenarios, the internet of things device may access the parsed IP address using multiple accesses, such as a ping command in ICMP protocol (internet control message protocol, internet Control Message Protocol, ICMP protocol for short), TCP protocol (transmission control protocol, transmission Control Protocol, TCP protocol for short), or UDP protocol (user datagram protocol, user Datagram Protocol, UDP protocol for short).

Further, the physical network device may access the parsed IP address at regular or irregular time, without limitation.

In this implementation, the internet of things device may access the parsed IP address from time to time. In this way, the new subdomain name and the IP address can be kept alive for the IP address corresponding to the new subdomain name.

In some alternative implementations, the method further includes: transmitting a retransmission instruction to the Internet of things equipment; the retransmission instruction is used for indicating: and if the current service domain name is the last service domain name in the service domain name list, retransmitting a service domain name list acquisition request after the dormancy preset time length.

In some application scenarios, in the process of accessing the service domain name list, if the last service domain name is currently being accessed, the internet of things device may sleep for a preset period of time after the access. The preset time period may be, for example, 50 seconds, 60 seconds, or the like.

In this way, the internet of things device can adjust the internal resources within the preset time length, so that more resources can be adjusted to reacquire the service domain name list and execute subsequent access operation, and the service realization rate is improved to a certain extent.

In some optional implementations, if the sub-domain name acquisition request sent by any one of the internet of things devices is received in step 103, sending the new sub-domain name to the internet of things device includes: if a subdomain name list acquisition request sent by any Internet of things equipment is received, sending a subdomain name list;

in some application scenarios, the internet of things device may request to acquire all sub-domain names, or may request to acquire a single sub-domain name, which is not limited herein. In these application scenarios, if all the sub-domains are acquired, all the sub-domains may be included in the sub-domain list, and if only a single sub-domain is acquired, only one sub-domain may be included in the sub-domain list.

In some application scenarios, for convenience of management, the physical network platform may, for example, set three interfaces, one of which is used for receiving a sub domain name list acquisition request and returning a sub domain name list, where all sub domain name information is included; the second step is to receive the service domain name list obtaining request and return the service domain name list, wherein the service domain name list comprises subdomain name information which is necessary to be accessed by the realization service; and thirdly, the method is used for receiving the target IP address and triggering the operation of the newly added sub domain name.

Thus, the method further comprises: sending a sub domain name keep-alive instruction to the Internet of things equipment; the subdomain name keep-alive instruction is used for indicating: aiming at each sub domain name in the sub domain name list, resolving an IP address corresponding to the sub domain name; and accessing the IP address a plurality of times to place the IP address in an accessible state.

Here, the process of keeping all the sub-domain names and the IP addresses alive by the internet of things device and the obtained technical effects may be the same as or similar to the process of keeping the service domain names and the IP addresses alive, which are not described herein.

In the implementation manner, all the sub domain names and the IP addresses are in an accessible state, and the reasons of access failure caused by no record can be removed under the condition that access of a certain IP address fails, so that other reasons of access failure can be paid more attention to, and the speed of searching for the reasons of access failure is improved.

It will be appreciated by those skilled in the art that in the above-described method of the specific embodiment, the written order of steps is not meant to imply a strict order of execution but rather should be construed according to the function and possibly inherent logic of the steps.

Referring to fig. 2, a flowchart of an IP address access method according to an embodiment of the present application is shown. The IP address access method can be applied to the Internet of things equipment. As shown in fig. 2, the IP address access method includes the following steps 201 to 203.

Step 201, sending a service domain name list acquisition request to an internet of things platform to acquire a service domain name list;

step 202, resolving an IP address corresponding to each service domain name in the service domain name list;

step 203, sending a new request to the platform of the internet of things under the condition that the access to the IP address fails, wherein the new request comprises the IP address; the new request is for a request: generating a new sub domain name according to the main domain name under the condition that the target IP address with failed access is determined to be a new IP address; storing the association relationship among the main domain name, the new sub domain name and the target IP address; if the service domain name acquisition request is received again, an updated service domain name list is sent; wherein the updated service domain name list includes the new sub-domain name.

It should be noted that the implementation process of the above steps 201 to 203 may be the same as or similar to the implementation process of the above steps 001 to 103, which is not repeated herein.

In this embodiment, the internet of things device may collect the IP address with failed access, and then may request the physical network platform to add a new sub-domain name under the main domain name already recorded for the physical network platform when determining that the target IP address is the new IP address.
