All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

An embodiment of the present invention provides a method for accelerating picture access, as shown in fig. 1, which is applied to a CDN node, and includes:

s101, receiving a picture access request sent by a first user terminal.

The picture access request comprises picture information of a picture to be accessed.

The first user side may comprise a terminal used by the first user accessing the picture. The first client may comprise a browser or a client.

Specifically, receiving a picture access request sent by a first user end may include:

and receiving a picture access request sent to the CDN node by a first user through a browser or a client.

The CDN nodes may be physical nodes or virtual nodes, and may include nodes in which a cloud picture service program is installed, for example, servers.

The picture information may include a picture request address and the like. Specifically, the user may access a web page through a browser or a client, where the web page includes the picture to be accessed, and the web page address may be considered as a picture request address of the picture to be accessed.

For example, a user inputs a domain name of a website to be accessed in a browser of the user, the browser analyzes the domain name to obtain an Internet Protocol Address (IP Address) corresponding to the domain name, and sends a picture access request including the IP Address to the CDN node. The specific CDN node in the content delivery network formed by the multiple CND nodes to which the picture access request is sent may be determined according to a specific policy, and may be understood as a CDN back-to-source policy. For example, the CDN node closest to the IP address in physical distance is determined as the finally determined CDN node, that is, the picture access request including the IP address is sent to the finally determined CDN node. Wherein, the CDN back-to-source strategy can be provided by the provider

S102, detecting whether the CDN cache of the CDN comprises the picture to be accessed or not through the picture information.

The CDN node may obtain a plurality of pictures in advance, and store the plurality of pictures in a CDN cache of the CDN node. Specifically, the plurality of pictures may be stored according to a correspondence relationship between picture information corresponding to each picture and each picture.

Therefore, after receiving the picture access request, the CDN node may parse the picture access request to obtain the picture information of the request to be accessed. And detecting whether the CDN cache comprises the picture to be accessed or not according to the picture information included in the picture access request.

If the CDN cache does not include the picture to be accessed, step S103 may be executed. If the CDN cache includes the picture to be accessed, the picture to be accessed may be obtained from the CDN cache, and the picture to be accessed is returned to the first user.

It is to be simply understood that, if the CDN cache is not hit, step S103 may be executed; if the picture to be accessed is hit in the CDN cache, the picture to be accessed can be obtained from the CDN cache, and the picture to be accessed is returned to the first user end. For example, the picture to be accessed is returned to the browser or client used by the first user, and so on.

S103, sending the picture access request to the cloud picture service node, so that the cloud picture service node processes the picture access request, and returning a picture to be accessed corresponding to the picture access request to the CDN node.

The cloud picture service node is responsible for capturing pictures and storing the pictures into the cloud picture service cache and the cloud storage platform. The cloud storage platform may be understood to include a cloud storage space, which may be managed by a cloud storage server.

Cloud storage refers to a system that integrates a large number of storage devices of different types in a network through application software to cooperatively work through functions such as cluster application, network technology or distributed file systems, and provides data storage and service access functions to the outside.

Specifically, the process of capturing the picture by the cloud picture service node and storing the picture in the cloud storage platform will be described in detail in the following embodiments, which are not described herein again. Therefore, when the CDN node does not include the picture to be accessed, the picture to be accessed can be obtained from a cloud picture service cache of the cloud picture service node or a cloud storage platform according to different conditions, and the picture to be accessed is returned to the first user terminal.

Specifically, the process of processing the picture access request and returning the picture to be accessed corresponding to the picture access request by the cloud picture service node according to different situations will be described in detail in the following embodiments, which are not repeated herein.

And S104, receiving the picture to be accessed returned by the cloud picture service node.

And S105, returning the picture to be accessed returned by the cloud picture service node to the first user terminal.

The first user terminal receives the picture to be accessed, and can load picture resources to realize the access to the picture.

In the embodiment of the invention, the picture to be accessed is not included in the CDN cache, the picture access request is sent to the cloud picture service node, so that the cloud picture service node processes the picture access request, the picture to be accessed corresponding to the picture access request is returned to the CDN node, and the CDN node returns the picture to be accessed to the user side when receiving the picture to be accessed returned by the cloud picture service node. In this way, when the picture to be accessed is not included in the CDN cache, the cloud picture service node is accessed, so that access pressure on the origin server can be alleviated.

An embodiment of the present invention provides a method for accelerating picture access, which is applied to a cloud picture service node as shown in fig. 2, and includes:

s201, receiving a picture access request sent by a CDN node.

The cloud picture service node receives a picture access request sent by the CDN node.

Specifically, the picture access request may include a request sent by the first user terminal to the CDN node. The first user terminal may include a browser or a client used by the first user, and the like.

Specifically, the first user may access the CDN node through a browser or a client, and when detecting that the CDN cache of the CDN node does not include a picture to be accessed, the CDN node may send a picture access request to the cloud picture service node.

S202, based on the picture information of the picture to be accessed, the picture access request is processed, and the picture to be accessed corresponding to the picture access request is returned to the CDN node.

Therefore, after receiving the picture access request, the cloud picture service node can analyze the picture access request to obtain the picture information of the request to be accessed.

And processing the picture access request according to the picture information included in the picture access request. Specifically, whether to continue accessing the cloud storage platform or not can be judged according to whether the cloud picture service cache of the cloud picture service node per se comprises different pictures to be accessed or not; and determining whether to continue to access the third-party service node according to the difference that whether the cloud storage platform comprises the picture to be accessed. Therefore, according to different conditions, different strategies are determined to acquire the picture to be accessed.

The third-party service node comprises an original position of the picture to be accessed, namely a real address corresponding to the picture to be accessed.

In the embodiment of the invention, the first user terminal receives the picture to be accessed, can load the picture resource and accesses the picture to be accessed.

In the embodiment of the invention, after receiving the picture access request sent by the CDN node, the cloud picture service node processes the picture access request and returns the picture to be accessed corresponding to the picture access request to the CDN node. In this way, access pressure to the origin server can be avoided. And the cloud picture service node can automatically process the picture access request and return the picture to be accessed when receiving the picture access request, and a user does not need to configure a back-source strategy of the CDN and a CDN acceleration domain name, so that the technical threshold of using picture acceleration by the user is greatly reduced. Meanwhile, the calculation complexity of the user side is reduced.

In an optional embodiment of the present invention, the picture access request may include picture information of a picture to be accessed.

Step S202: processing the picture access request, and returning a picture to be accessed corresponding to the picture access request, as shown in fig. 3 (a), the processing may include:

s2021, detecting whether the cloud picture service cache of the cloud picture service node itself includes a picture to be accessed according to the picture information.

Specifically, the cloud picture service node acquires a plurality of pictures in advance, and stores the plurality of pictures in a cloud picture service cache of the cloud picture service node. Specifically, the plurality of pictures may be stored in correspondence between picture information corresponding to each picture and each picture.

In this way, the cloud picture service node may detect whether the to-be-accessed picture is included in the cloud picture service cache according to the picture information included in the picture access request.

If so, that is, if the cloud picture service cache includes the picture to be accessed, step S2022 may be performed; if not, that is, if the cloud picture service cache does not include the picture to be accessed, step S2023 may be executed.

And S2022, obtaining the picture to be accessed from the cloud picture service cache, and returning the picture to be accessed to the CDN node.

Specifically, the picture to be accessed may be returned to the first user terminal through the CDN node. For example, the cloud picture service node obtains the picture to be accessed from the cloud picture service cache, and sends the picture to be accessed to the CDN node, and the CDN node receives the picture to be accessed sent by the cloud picture service node, and forwards the picture to be accessed to a first user terminal, such as a browser or a client used by a user.

S2023, accessing the cloud storage platform.

And if the cloud picture service cache does not contain the picture to be accessed, accessing the cloud storage platform.

Specifically, accessing cloud storage may include: and judging whether the picture to be accessed is stored in the cloud storage platform, if so, namely, if the picture to be accessed is stored in the cloud storage platform, executing the step S2024.

And S2024, obtaining the picture to be accessed from the cloud storage platform, and returning the picture to be accessed to the CDN node.

Namely, when the picture to be accessed is stored on the cloud storage platform, the picture to be accessed is obtained from the cloud storage platform, and the picture to be accessed is returned to the CDN node.

Specifically, the picture to be accessed may be returned to the first user terminal through the CDN node. For example, the cloud picture service node acquires the picture to be accessed from the cloud storage platform, and sends the picture to be accessed to the CDN node, and the CDN node receives the picture to be accessed sent by the cloud picture service node and forwards the picture to be accessed to a first user terminal, such as a browser or a client used by a user.

In an alternative embodiment of the present invention, as shown in fig. 3 (b), if the picture to be accessed is not stored in the cloud storage, step S2025 may be executed.

And S2025, obtaining the picture to be accessed from the third-party service node, and returning the picture to be accessed to the CDN node.

And when the picture to be accessed is not stored on the cloud storage platform, obtaining the picture to be accessed from the third-party service node, and returning the picture to be accessed.

That is, when the picture to be accessed is not included in the CDN node, the cloud picture service cache of the cloud picture service node, or the cloud storage platform, the picture to be accessed is obtained from the original location where the picture to be accessed is stored, and the picture to be accessed is returned.

Because the third-party service node includes the original position of the picture to be accessed, that is, when the picture to be accessed is not included in the CDN node, the cloud picture service cache of the cloud picture service node, or the cloud storage platform, the third-party service node is accessed, which can ensure that the picture to be accessed can be acquired, that is, the reliability of access is ensured.

Specifically, the to-be-accessed picture is returned, and the to-be-accessed picture can be returned to the first user terminal through the CDN node. If the cloud picture service node interacts with a third-party service node, the picture to be accessed is obtained from the third-party service node, the picture to be accessed is sent to the CDN node, the CDN node receives the picture to be accessed sent by the cloud picture service node, and the picture to be accessed is forwarded to a first user terminal, such as a browser or a client used by a user.

In the embodiment of the invention, the first user terminal, such as a browser or a client and the like, receives the picture to be accessed, can load the picture resource and access the picture to be accessed.

On the basis of the foregoing embodiment, in an optional embodiment, when the to-be-accessed picture is not stored on the cloud storage platform, after the to-be-accessed picture is acquired from the third-party service node, the method may further include:

and storing the picture to be accessed to the cloud storage platform.

In an implementation manner, as shown in fig. 4, after the step S2025 obtains the picture to be accessed from the third-party service node, and returns the picture to be accessed to the CDN node, the method may further include the step S2026: and storing the picture to be accessed to the cloud storage platform.

In another implementation manner, after the picture to be accessed is obtained from the third-party service node, the processes of returning the picture to be accessed and storing the picture to be accessed to the cloud storage platform are performed at the same time.

Therefore, the cloud picture service nodes are added, and the cloud picture service nodes can automatically capture the pictures to be accessed. And when a next request is made to access the picture to be accessed, the picture to be accessed can be directly obtained from the cloud storage, and a third-party service node does not need to be accessed to obtain the picture to be accessed, so that the access speed can be increased. And the picture is not required to be uploaded manually by the user, so that the operation process of the user is simplified.

On the basis of the above embodiment, the embodiment of the present invention may further include a process in which the cloud picture service node stores the picture in the cloud storage platform in advance. And the process of pre-storing the pictures by the cloud picture service node can be carried out in real time and can be carried out simultaneously with the process of accessing the pictures by the user.

Specifically, the embodiment of the present invention may further include the following steps:

and A1, receiving picture address information sent by a second user terminal.

The second user terminal may be a terminal used by the second user. The second user may include a service provider providing a cloud picture service, and may also be understood as a customer requesting a cloud storage space.

The picture address information is simply understood as information indicating a picture address, wherein the picture address may include an address where a picture to be stored is stored.

And A2, obtaining the picture to be stored from the picture address corresponding to the picture address information.

In one implementation, the picture address may be located at a third party service node that stores the picture.

The cloud picture service node can interact with a third-party service node, and a picture to be stored is obtained from a picture address corresponding to the picture address information in the third-party service node.

And A3, storing the picture to be stored to a cloud storage platform.

Specifically, the picture address and the picture to be stored corresponding to the picture address may be correspondingly stored. Or a plurality of pictures to be stored can be stored according to other picture information of the pictures to be stored. Such as the address of the website to access the picture to be stored, which may also be referred to as a picture access address, and so on.

The cloud picture service node stores a plurality of pictures in the cloud storage platform in advance, so that when the pictures to be accessed by the users accessing the pictures are not included in the CDN node cache and the cloud picture service cache, the cloud picture service node can acquire the pictures to be accessed from the cloud storage platform and return the pictures to be accessed to the CDN node, so that the CDN node receives the pictures to be accessed and returns the pictures to be accessed to the user terminal used by the users accessing the pictures, and the users can access the pictures.

In order to speed up the process of accessing the picture by combining the CDN node, a CDN back-to-source policy needs to be configured, that is, when the user accesses the picture, to which CDN node the picture access request is sent. In an alternative embodiment, the automatic configuration may be performed by the cloud picture service node.

Specifically, after receiving the picture address information sent by the second user, the embodiment of the present invention may further include:

and B1, determining picture acceleration address information corresponding to the picture address information.

The picture acceleration address information includes a CDN node address.

And B2, returning the picture acceleration address information to the second user side so that the second user configures the access address of the picture to be stored as a CDN node address.

Therefore, a source returning strategy of the CDN and a CDN acceleration domain name do not need to be configured by a user, and the technical threshold of using pictures for acceleration by the user is greatly reduced. Meanwhile, the calculation complexity of the user side is reduced.

An embodiment of the present invention further provides a specific embodiment, as shown in fig. 5, including:

s501, the browser accesses the CDN node.

The first user accesses the CDN node through a browser.

In another optional implementation manner, the first user may also access the CDN node through a client.

Specifically, a picture access request may be sent to the CDN node. The picture access request comprises picture information of a picture to be accessed.

Therefore, the CDN node receives the picture access request, analyzes the access request and obtains the picture information. And detecting whether the CDN cache of the user comprises the picture to be accessed or not through the picture information.

If the CDN cache includes a picture to be accessed, then step S502 is executed; if the CDN cache does not include the picture to be accessed, step S503 is executed.

And S502, returning the picture to be accessed.
