The basic idea of a Content Delivery Network (CDN) is to avoid bottlenecks and links on the internet that may affect the data transmission speed and stability as much as possible, so that Content transmission is faster and more stable. The CDN is a layer of intelligent virtual network on the basis of the existing Internet, which is formed by placing node servers at all positions of the network. The CDN can redirect the request of the user to the service node closest to the user in real time according to the network traffic and the comprehensive information such as the connection of each node, the load condition, the distance to the user, and the response time. The method aims to enable the user to obtain the required content nearby, solve the problem of congestion of the Internet network and improve the response speed of the user for accessing the website. The current CDN mainly relies on the existing Domain Name System (DNS) technology to access and resolve a Domain Name, that is, determines the most appropriate Internet Protocol (IP) address corresponding to the Domain Name through recursive query, and then returns the IP address to the user.
However, the inventors found that at least the following problems exist in the prior art: the domain name access and resolution method of the CDN based on the DNS technology has the following problems:
1. the query speed is low; in the worst case, it needs to go through many times of recursive operations to query the IP information corresponding to the domain name.
2. The query result is influenced by the caching time of the edge node; sometimes the domain name has changed, but the domain name change cannot be effective in real Time due To Time To Live (TTL) of domain name resolution in the DNS server, resulting in an error in query result.
3. Since the authoritative domain name server is easily attacked, a large-area service fault is caused, and the use of the CDN system is seriously influenced.

Compared with the prior art, the super block chain node issues the block storing the first domain name and the corresponding information of the IP base to the block chain network, so that the corresponding information can be synchronized to the user end block chain node. Because the corresponding information is stored in the block chain of the user-side block chain node, the user-side block chain node can determine the access IP address by inquiring the block chain, and the inquiring speed is improved. In addition, because the corresponding information of the first domain name and the IP base is stored by adopting the block chain technology, the corresponding information of the first domain name and the IP base cannot be tampered, and the condition of domain name hijacking can be prevented.

However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The domain name access method and the domain name resolution method provided by the embodiment of the invention are applied to a domain name resolution system of the CDN, and the structure of the domain name resolution system of the CDN is shown in fig. 1 and includes a domain name information management module 101, a user end block chain node 102, a super block chain node management module 103, and a super block chain node 104. The domain name information management module 101 is configured to manage and maintain relevant information, such as corresponding information between the first domain name and the IP library. As shown in fig. 2, the domain name information management module 101 includes a domain name maintenance module 201, a second domain name chain maintenance module 202, and an IP scheduling module 203. The domain name maintenance module 201 is configured to maintain a first domain name and a corresponding relationship between the first domain name and a second domain name chain, where the corresponding relationship between the second domain name and an IP library is stored in the second domain name chain. The domain name maintenance module 201 can interact with the super block link point, so that the CDN can send the first domain name and the information corresponding to the IP library to the super block link node. The second domain name chain maintenance module 202 is configured to maintain a corresponding relationship between the second domain name and the IP library. The IP scheduling module 203 is used for scheduling faults of CDN service nodes. The user-side blockchain node 102 is configured to resolve the first domain name input by the user to obtain the access IP address. The super block chain node management module 103 is configured to manage information of the super block chain node. The super block chain node is used for generating a block according to the first domain name and the corresponding information of the IP library and issuing the block to the block chain network.
It should be noted that the domain name access method, the domain name resolution method, and other related methods mentioned in this embodiment may be implemented by an intelligent contract composed of automated script codes, where the intelligent contract is installed on a block chain of a super block chain node, and the super block chain node and a user-side block chain node execute the method mentioned in this embodiment through the intelligent contract.
It should be noted that, in practical applications, the CDN further includes other modules such as CDN service nodes, as will be understood by those skilled in the art. Each module referred to in this embodiment is a logical module, and in practical applications, one logical unit may be one physical unit, may be a part of one physical unit, and may be implemented by a combination of a plurality of physical units. In addition, in order to highlight the innovative part of the present invention, elements that are not so closely related to solving the technical problems proposed by the present invention are not introduced in the present embodiment, but this does not indicate that other elements are not present in the present embodiment.
The first embodiment of the invention relates to a domain name access method, which is used for a super block chain node. By executing the domain name access method, the first domain name is accessed to the CDN, so that the response speed of a user for accessing the website is improved. The specific flow of the domain name access method is shown in fig. 3.
Step 301: and acquiring corresponding information of the first domain name and the IP library provided by the CDN.
Specifically, the first domain name is a domain name of a website that needs to access the CDN, and the correspondence information between the first domain name and the IP library may be a correspondence between the first domain name and the IP library, or a correspondence between the first domain name and a second domain name chain.
Step 302: and generating a block in which the corresponding information is stored according to the corresponding information of the first domain name and the IP library.
Specifically, in the process of generating a block storing the first domain name and the corresponding information of the IP base, the super block chain node may encrypt the corresponding information by using an encryption technique.
It is worth mentioning that, since the corresponding information of the first domain name and the IP base is stored by using the block chain technology, the corresponding information cannot be tampered with, and the domain name hijacking can be prevented.
Step 303: and issuing the block in which the corresponding information of the first domain name and the IP base is stored to other block chain nodes in the block chain network.
In particular, the blockchain network includes user-side blockchain nodes and super blockchain nodes. After other block chain nodes of the block chain network receive the blocks stored with the corresponding information, the blocks stored with the corresponding information are updated to the respective block chains.
In a specific implementation, it may be preset that data of the super block chain node is completely trusted, so that each node in the block chain network can add a block issued by the super block chain node to its respective block chain.
It is worth mentioning that, because the block chain has a high synchronization speed, the information synchronization can be completed when the user-side block chain node accesses the network, thereby avoiding the influence of the persistence time on the query result.
It should be noted that the corresponding information is recorded in the block chain of the user-side block chain node, so that when the authoritative domain name server is attacked, the user-side block chain node can determine the access IP address by inquiring the local block chain, and further obtain the information of the accessed website.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, in the domain name access method provided by the embodiment, the super-block chain node issues the block storing the corresponding information of the first domain name and the IP base to the block chain network, so that the corresponding information can be synchronized to the user-side block chain node. Because the corresponding information is stored in the block chain of the user-side block chain node, the user-side block chain node can determine the access IP address by inquiring the block chain, and the inquiring speed is improved. In addition, due to the characteristics of the block chain, the user-side block chain nodes can be immediately synchronized to the corresponding information when networking is carried out, and the influence of the persistence time on the query result is avoided. And because the corresponding information is stored in the block chain of the user-side block chain node, even if the authoritative domain name server is attacked, the user-side block chain node can still determine the access IP address and acquire the information of the accessed website.
A second embodiment of the present invention relates to a domain name access method. The present embodiment is further detailed with respect to the first embodiment, and specifically describes a process in which the CDN determines the corresponding information of the first domain name and the IP repository according to the corresponding relationship between the first domain name and the second domain name and the corresponding relationship between the second domain name and the IP repository.
Specifically, as shown in fig. 4, the domain name access method of the present embodiment includes steps 401 to 408, wherein steps 405 to 407 are substantially the same as steps 301 to 303 of the first embodiment, and are not repeated herein. The following mainly introduces the differences:
step 401: the CDN acquires a domain name access request of the website.
Specifically, when requesting to access the CDN, the website sends a domain name access request to the CDN. The domain name access request includes a first domain name of the website. And after determining that the website meets the preset conditions, the CDN executes the subsequent steps. The preset condition comprises that the website is already recorded and/or the website pays the service fee.
Step 402: and the CDN allocates a second domain name for the website according to the service type of the website.
Specifically, the second domain name is an internal domain name assigned by the CDN to a website that needs to access the CDN.
It should be noted that, in practical applications, the CDN may also allocate the second domain name to the website that needs to access the CDN according to other principles, and this embodiment does not limit the manner in which the CDN allocates the second domain name to the website that needs to access the CDN.
Step 403: and the CDN determines an IP library corresponding to the second domain name according to the allocated second domain name.
Specifically, a second domain name chain of the CDN stores a correspondence between the second domain name and the IP repository, and determines the correspondence between the second domain name and the IP repository according to the second domain name chain.
Step 404: and the CDN determines corresponding information of the first domain name and the IP library according to the corresponding relation between the first domain name and the second domain name and the corresponding relation between the second domain name and the IP library, and sends the corresponding information to the super block chain node.
Step 405: and the super block chain node acquires corresponding information of the first domain name and the IP library provided by the CDN.
Step 406: and the super block chain node generates a block in which the corresponding information is stored according to the corresponding information of the first domain name and the IP library.
Step 407: the super block chain node issues the block in which the corresponding information of the first domain name and the IP base is stored to other block chain nodes in the block chain network.
Step 408: and other block chain nodes update the blocks in which the corresponding information of the first domain name and the IP base is stored to the respective block chains.
It should be noted that, as can be understood by those skilled in the art, in practical application, the CDN may further send other scheduling information to the super block chain node, and the super block chain node generates a block in which the scheduling information is stored according to the received scheduling information, and sends the block to the block chain, so that the scheduling information is synchronized to the user end block chain node.
The following describes a process of synchronizing the scheduling information to the block chain, taking a case where a CDN service node of the CDN fails as an example. As shown in fig. 5, the method for synchronizing scheduling information includes steps 501 to 506.
Step 501: and after finding that a certain CDN service node has a fault, an IP scheduling module of the CDN marks the IP address of the CDN service node.
Step 502: and the CDN determines fault information according to the marked IP address. The fault information includes an IP address of the failed CDN service node.
Step 503: and the CDN sends the fault information to the super block chain node.
Step 504: and the super block chain node acquires the fault information provided by the CDN, and generates a block for storing the fault information according to the fault information.
Step 505: the super blockchain node issues the block in which the fault information is stored to other blockchain network nodes in the blockchain network.
Step 506: and other block chain nodes update the blocks stored with the fault information into respective block chains.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, in the domain name access method provided in this embodiment, the CDN sends scheduling information to the super block chain node, and the super block chain node synchronizes the information to the user end block chain node, so that the user end block chain node can obtain the scheduling information of the CDN in time, and provide an effective access IP address for the user according to the scheduling information.
The third embodiment of the present invention relates to a domain name resolution method, which is used for a user-side block chain node, wherein the user-side block chain node requests to access a terminal of a certain website through a browser or a browser plug-in, etc. As shown in fig. 6, the domain name resolution method includes:
step 601: and acquiring the first domain name. The first domain name is a domain name of a website needing to be accessed to the CDN.
Specifically, the user-side blockchain node may obtain the first domain name sent by the user-side blockchain node through a browser plug-in or a special browser issued by a CDN manufacturer, or by using some system-level resolution hijacking software.
It should be noted that, because the domain name resolution method and the domain name resolution method according to the embodiments of the present invention have the aforementioned advantages, a user is more willing to select a CDN vendor that uses the domain name access method and the domain name resolution method according to the embodiments of the present invention. When the first CDN manufacturer uses the domain name access method and the domain name resolution method according to the embodiments of the present invention, if a user wants to deliver traffic of a part of a region to other CDN manufacturers, the user needs to coordinate with the first CDN manufacturer to change the domain name resolution method of the user website, which increases operation difficulty and cost, and is beneficial to maintaining user stickiness.
Step 602: and determining the IP library corresponding to the first domain name according to the corresponding information of the first domain name and the IP library stored in the block chain of the user-side block chain node.
Specifically, the IP library includes an IP address of the CDN service node. The user terminal block chain node judges whether the block chain has corresponding information of a first domain name input by a user or not by inquiring data on a local block chain, if yes, an IP library corresponding to the first domain name is determined according to the data stored in the block chain, and if not, the user terminal block chain node prompts the user that a website requested to be accessed is not accessed to the CDN, or the user terminal block chain node analyzes the first domain name based on a DNS technology to determine an IP address to be accessed. The domain name resolution process of the user terminal block chain node based on the DNS technology is as follows: the user terminal block chain node requests a local DNS server for resolving the first domain name, the local DNS server sends the resolving request for the first domain name to an authoritative domain name server of the website, the authoritative domain name server determines the most appropriate CDN service node according to a series of strategies, the IP address of the most appropriate CDN service node is sent to the user terminal block chain node, and the user terminal block chain node requests information of the website from the CDN service node.
It should be noted that, after determining that the corresponding information corresponding to the first domain name input by the user is not stored in the blockchain, the user-side blockchain node resolves the first domain name based on the DNS technology, so that the domain name resolution method provided by the embodiment can be integrated with the existing DNS resolution system.
It is worth mentioning that, because the user-side blockchain node determines the corresponding information through the local blockchain, the access IP address corresponding to the first domain name does not need to be queried from the local domain name server, and the query speed of the user-side blockchain node is improved.
Step 603: and determining an access IP address according to the IP library corresponding to the first domain name.
Compared with the prior art, in the domain name resolution method provided by the embodiment, the corresponding information is stored in the block chain of the user-side block chain node, and the user-side block chain node can determine the access IP address by inquiring the block chain, so that the inquiry speed is improved. In addition, due to the characteristics of the block chain, the user-side block chain nodes can be immediately synchronized to the corresponding information when networking is carried out, and the influence of the persistence time on the query result is avoided. And because the corresponding information is stored in the block chain of the user-side block chain node, even if the authoritative domain name server is attacked, the user-side block chain node can still determine the access IP address, and the information of the accessed website is obtained by accessing the CDN service node corresponding to the IP address.
The fourth embodiment of the present invention relates to a domain name resolution method, which is a further refinement of the third embodiment, and specifically describes a process for determining an access IP address by a user-side block chain node.
Specifically, as shown in fig. 7, the present embodiment includes steps 701 to 704, where step 701 and step 702 are substantially the same as step 601 and step 602, and are not described herein again. The following mainly introduces the differences:
step 701 and step 702 are performed.
Step 703: the IP address of the user-side blockchain node is determined.
Specifically, the user-side blockchain node transmits a request for acquiring an IP address of the user-side blockchain node to the IP address detection apparatus. The IP address detection device determines the IP address of the user terminal block chain node according to the request, determines response information to the request according to the IP address of the user terminal block chain node, and sends the response information to the user terminal block chain node. And the user-side block chain node acquires response information of the IP address detection device to the request, and determines the IP address of the user-side block chain node according to the response information.
For example, the user-side blockchain node sends a mail to the IP address detection device, the IP address detection device determines the IP address of the user-side blockchain node according to the mail attribute, and sends response information including the IP address of the user-side blockchain node to the user-side blockchain node, and the user-side blockchain node determines its own IP address according to the response information.
It should be noted that, in practical applications, the IP address of the user-side blockchain node may also be determined in other manners, and this embodiment does not limit the manner of determining the IP address of the user-side blockchain node.
It is worth mentioning that the traffic scheduling is performed according to the own IP address of the user-side blockchain node, so that the query result is not affected by the IP address of the authoritative server configured by the user at the user-side blockchain node, and the accuracy is high.
Step 704: and selecting the IP address of one CDN service node from an IP library corresponding to the first domain name as an access IP address according to the IP address of the user terminal block chain node.
In specific implementation, the user-side blockchain node selects an IP address of a CDN service node as an access IP address according to its own IP address and other conditions such as network traffic, and requests information of an access website from the access IP address.
It should be noted that before the user-side blockchain node is selected, the IP addresses in the IP library may be screened first, and the IP addresses corresponding to the CDN service nodes that cannot normally operate are removed from the IP library. The screening process comprises the following specific steps: and the user terminal block chain node eliminates the IP address of the failed CDN service node in the IP library corresponding to the first domain name according to the fault information stored in the block chain. The fault information includes an IP address of the failed CDN service node.
It is worth mentioning that the IP address of the CDN service node that cannot normally work is removed from the IP library, so as to avoid the user end block link node from initiating a request to the failed CDN service node.
Compared with the prior art, in the domain name resolution method provided by the embodiment, the corresponding information is stored in the block chain of the user-side block chain node, and the user-side block chain node can determine the access IP address by inquiring the block chain, so that the inquiry speed is improved. In addition, due to the characteristics of the block chain, the user-side block chain nodes can be immediately synchronized to the corresponding information when networking is carried out, and the influence of the persistence time on the query result is avoided. And because the corresponding information is stored in the block chain of the user-side block chain node, even if the authoritative domain name server is attacked, the user-side block chain node can still determine the access IP address, and the information of the accessed website is obtained by accessing the CDN service node corresponding to the IP address. In addition, the IP of the user-side block chain node is detected to obtain the real IP address of the user-side block chain node, and the traffic scheduling is carried out according to the IP address, so that the query result is not influenced by the IP address of an authoritative server configured by the user at the user-side block chain node, and the accuracy is high.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
