In order to enable the single stack IPv4 client to access the IPv6 network, the existing access request processing method may perform type conversion and analysis on a request sent by the single stack IPv4 client, and feed back the analyzed target address after being converted again to the client, so that the single stack IPv4 client accesses resources of the target address. However, the current access request processing method has a slow response speed, and reduces the access experience of a single-stack IPv4 client to IPv6 network resources.

Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

In recent years, global IPv4 addresses are largely occupied, so that assignable IPv4 addresses are few, which promotes the gradual popularization of IPv6 networks, and IPv6 networks receive great promotion and encouragement, so that IPv6 networks are more smoothly, more safely and more stably accessed to the original IPv4 basic networks of users, and are receiving wide attention.

At present, based on the original infrastructure and the current internet situation, the current situation is still in the transition stage from the IPv4 network to the IPv6 network, and in the transition stage, the scale of the IPv6 network is increasingly large, so that the IPv6 network resource is accessed more and more frequently. Because the intranet is difficult to be completely upgraded to IPv6 in a short period of time, a plurality of single stack IPv4 clients need to access the IPv6 network.

In order to enable a single stack IPv4 client to access an IPv6 network, and most resources in the network exist in a Domain Name manner, the existing access request processing method may use a Domain Name System IPv4& IPv6 (Domain Name System IPv4& IPv6, DNS 46) proxy server to perform type conversion on a request sent by the single stack IPv4 client, so as to convert an a record request sent by the single stack IPv4 client into an AAAA record request capable of accessing the IPv6 network, perform Domain Name resolution on the AAAA record request using the Domain Name System (DNS) server, convert an analyzed target address again, and feed the converted target address back to the client, so that the single stack IPv4 client accesses resources of the target address.

Specifically, the logic of the existing access request processing method is as follows: and the single stack IPv4 client side initiates an A record request to the DNS46 proxy server, and if the DNS46 proxy server finds out the analyzed target address of the A record request from a predefined cache table, the analyzed target address is directly returned to the single stack IPv4 client side. If the DNS46 proxy server does not find the analyzed target address of the A record request from a predefined cache table, the DNS46 proxy server converts the A record request sent by the single stack IPv4 client into an AAAA record request, and performs domain name analysis on the AAAA record request by using the DNS server to obtain an IPv6 target address, then the DNS46 proxy server converts the IPv6 target address into an IPv4 target address based on a preset mapping relation between IPv4 and IPv6, and finally feeds the IPv4 target address back to the client, so that the single stack IPv4 client can access the resource of the IPv6 target address, namely the single stack IPv4 client can access the network resource of IPv 6.

However, based on the current access request processing method, the request sent by the DNS46 proxy server to the DNS server only includes an AAAA record request, so that the DNS server can only analyze the AAAA record request, and if the DNS server cannot analyze the IPv6 target address, the single stack IPv4 client or the DNS46 proxy server needs to resend the request, so that the DNS server analyzes the request again, which results in a slow response speed of the single stack IPv4 client and reduces the access experience of the single stack IPv4 client on IPv6 network resources.

In order to solve the above problem, an embodiment of the present disclosure provides a method capable of increasing response speed of an access request processing method, so as to improve access experience of a single stack IPv4 client on an IPv6 network resource.

Fig. 1 shows an architecture diagram of an access request processing system according to an embodiment of the present disclosure.

As shown in fig. 1, the architecture diagram may include a single stack client 101, an access request processing device 102, and a request parsing device 103. The single stack client 101 may include a mobile phone, a tablet computer, a desktop computer, a notebook computer, a vehicle-mounted terminal, a wearable device, an all-in-one machine, and an intelligent home device, and may also include a virtual machine or a simulator-simulated device. The access request processing device 102 may be a DNS46 proxy server, the request analysis device 103 may be a DNS server, and both the access request processing device 102 and the request analysis device 103 may be devices with storage and computing functions, such as a cloud server or a server cluster.

Based on the above-mentioned architecture, when the single stack client 101 wants to access a network resource having an IPv4 network resource and an IPv6 network resource, the single stack client 101 may send a first access request to the access request processing device 102, where the first access request is a fourth version internet protocol request, that is, the single stack client 101 is a single stack IPv4 client, the first access request is an a record request, the access request processing device 102 generates a corresponding second access request according to the first access request, the second access request is a sixth version internet protocol request, and the second access request and the single stack client carried by the first access request have the same domain name, that is, the second access request is an AAAA record request, the access request processing device 102 sends the second access request corresponding to the first access request and the first access request to the request resolution device 103, the request resolution device 103 may be a DNS server, and resolves the first access request and the second access request, and the target address is a sixth version protocol address or a fourth version protocol address, so as to implement performing two access requests, obtain a sixth version target address, that the target version internet protocol address is a sixth version internet protocol address, and return the single stack access request to the access request processing device 101 or the fourth version internet protocol address, and return the target internet protocol request to the internet protocol processing device 102 based on the fourth version internet protocol.

Therefore, based on the above architecture, the access request processing device can send the first access request and the second access request to the request analysis device at the same time, so that the request analysis device analyzes the two requests to analyze the IPv6 target address or the IPv4 target address, and returns the analyzed IPv6 target address or the IPv4 target address to the single stack client, and therefore, the access request processing device does not need to resend the request and analyze the request again, and therefore, the response speed of the single stack IPv4 client is improved, and the access experience of the single stack IPv4 client on the IPv6 network resource is improved.

Fig. 3 is an architecture diagram illustrating another access request processing method provided by an embodiment of the present disclosure.

As shown in fig. 3, the architecture diagram may include a single stack client 301, a DNS46 proxy server 302, an IPv4 DNS server 303, and an IPv6 DNS server 304.

Specifically, after receiving a first access request sent by a single stack IPv4 client, an access request processing device searches whether an access record of the single stack IPv4 client exists from a predefined cache table, and if the access record does not exist, it indicates that the single stack IPv4 client has not accessed an IPv4 network resource or an IPv6 network resource, or if the access record of the single stack IPv4 client has failed, it searches whether a domain name of the single stack IPv4 client exists from a predefined domain name tag table, and if the domain name of the single stack IPv4 client exists, it indicates that the single stack IPv4 client has accessed the IPv6 network resource, it sends only a second access request corresponding to the first access request to a request resolution device, so that the request resolution device resolves the second access request to determine a sixth version internet protocol address, and receives the sixth version internet protocol address returned by the request resolution device as a target address, that is to determine a network resource corresponding to the sixth version internet protocol address that the single stack IPv4 client can access; if the domain name of the single stack IPv4 client exists and the request analysis equipment does not analyze the protocol address corresponding to the second access request, the request analysis equipment cannot analyze the domain name of the single stack client carried by the second access request, the analysis message of the request analysis equipment is deleted, the analysis message comprises data of the protocol address corresponding to the second access request, the domain name of the single stack client carried by the first access request marked in a predefined domain name marking table is deleted, the first access request is retransmitted to the request analysis equipment, the request analysis equipment analyzes the domain name of the single stack client carried by the first access request, and receives the fourth version Internet protocol address corresponding to the first access request returned by the request analysis equipment as a target address, namely, the network resource corresponding to the fourth version Internet protocol address which can be accessed by the single stack IPv4 client is determined.

In still other embodiments of the present disclosure, after S210, the access request processing method may further include:

if the predefined cache table comprises an access address corresponding to the first access request, taking the access address corresponding to the first access request as a target address;

Therefore, in the embodiment of the present disclosure, after receiving a first access request sent by a single stack client, according to whether an access address corresponding to the first access request is recorded in a predefined cache table and whether a domain name of the single stack client carried by the first access request is marked in a predefined domain name marking table, only the first access request is sent to a request resolution device, or the first access request and a second access request are sent to the request resolution device, or only the second access request is sent to the request resolution device, so that the request resolution device resolves the domain name of the single stack client carried by the received access request to obtain a target address, which is applicable to access request processing methods in multiple scenes, and flexibility of processing the access request is extended.

In this embodiment of the present disclosure, after S230, the access request processing method may further include:

and if the target address is the sixth version Internet protocol address, marking the domain name of the single stack client corresponding to the target address to a predefined domain name marking table.

Specifically, after receiving a target address returned by the request resolution device, the access request processing device determines whether the target address is a sixth version internet protocol address, if so, marks a single-stack client domain name corresponding to the target address to a predefined domain name mark table, so as to determine whether the predefined domain name mark table has a single-stack client domain name carried by a subsequent access request when receiving the subsequent access request, if so, only sends a second access request corresponding to the subsequent access request to the request resolution device, and if not, sends the subsequent access request and a second access request corresponding to the subsequent access request to the request resolution device.

Therefore, in the embodiment of the present disclosure, after receiving a target address returned by a request resolution device, it may be determined whether the target address is a sixth version internet protocol address, if so, a single stack client domain name corresponding to the target address is marked to a predefined domain name mark table, so that when receiving a subsequent access request, it is determined whether the predefined domain name mark table has a single stack client domain name carried by the subsequent access request, if so, only a second access request corresponding to the subsequent access request is sent to the request resolution device, and if not, the subsequent access request and a second access request corresponding to the subsequent access request are sent to the request resolution device.
