Therefore, the first CDN node can obtain the domain name configuration information through the second CDN node, and obtain the feedback content corresponding to the access request by using the domain name configuration information. After the feedback content is provided to the user terminal, the user terminal can output the feedback content for the user.

The user side may generate a domain name access request after detecting a domain name input by a user and triggering an access operation, and send the domain name access request to the first CDN node. The domain name access request may include a domain name, which may be a domain name of a website or a webpage that the user needs to access. In general, the second CDN node may be a server that may obtain configuration information related to the domain name, or the like.

The domain name configuration information may be information such as functional data, identity information, access authority, timing standard, charging standard and/or certificate required in the domain name access process, and the domain name configuration information in the embodiment of the present application is information required to be used in the domain name access process, and the specific type of the information is not limited too much.

The collaboration device 104 of the second CDN node may be a content management Agent. The second CDN node may pull domain configuration information corresponding to the domain access request from the content management Agent, and feed the domain configuration information back to the first CDN node.

When the first CDN node provides the domain name access request to the second CDN node, the domain name access request may be sent to the second CDN node in a format of an http (HyperText Transfer Protocol) request. As a possible implementation manner, when the domain name access request initiated by the user side is in an http format, the first CDN node may add some parameter information, for example, parameter information such as a first ID (Identity document) identifier or a grayscale parameter of the first CDN node, and send the http request added with the parameter information to the second CDN node.

The DNS server can acquire the domain name in the domain name access request, inquire the CDN node corresponding to the domain name, and complete the inquiry work through the CDN node.

The first CDN node may be a CDN node closer to the user, may quickly receive a domain name access request of the user, and respond to the domain name access request. The DNS server may store an IP address of an access server corresponding to a domain name, that is, an IP address of a second CDN node, but the DNS server is affected by factors such as distance, and when the CDN node actually works, a domain name access request sent by a user is actually received by a first CDN node. After querying a second CDN node corresponding to a domain name in the domain name access request in the DNS server, the first CDN node may obtain an IP address of the second CDN node, and at this time, the second CDN node may provide the domain name access request to the second CDN node, and the access processing process of the first CDN node is completed through a cooperative function of the second CDN node.

Optionally, based on the DNS server, querying the second CDN node corresponding to the domain name access request may specifically include: and inquiring the IP address of the second CDN node with the lost domain name access request based on the DNS server. The providing the domain name access request to the second CDN node provided by the DNS server may specifically include: and providing a domain name access request to a second CDN node corresponding to the IP address provided by the DNS server.

In some embodiments, in order to ensure the security of the access process, the domain name access request initiated by the user side is generally encrypted by using a private key and a public key, and if the actual domain name data is to be obtained, the obtained domain name access request needs to be decrypted by using the domain name private key to obtain the domain name access data. When the domain name access request initiated by the user is decrypted, the decryption can be specifically performed through a private key corresponding to the domain name access request. The private key may include: static credentials and dynamic credentials that are dynamically configured by the user.

The decryption work of the domain name access request is completed at the certificate center node, so that the private key of the domain name is uniformly managed, and the phenomenon of private key leakage is avoided. When the management and control device is not configured, the first CDN node is ensured to work normally and safely.

In one possible design, the first CDN node queries the certificate authority node 205 for private keys for multiple domain names that may be stored therein. The decrypting, by the first CDN node 202, the domain name access request based on the certificate center node 205 to obtain domain name access data corresponding to the domain name access request may specifically include:

sending a domain name access request to a certificate center node; the domain name access request is obtained by encrypting domain name access data based on a private key by a user side; receiving domain name access data sent by a certificate center node.

As shown in fig. 5, the cell phone M1 may send 501 a domain name access request to the first CDN node M2, for example, an access request of an a web page, where the access request includes a domain name of the a web page.

The first CDN node M2 may receive the domain name access request sent by the cell phone M1.

In practical applications, in order to ensure the security of information, the domain name access request sent by the cell phone M1 is encrypted based on a private key, and the first CDN node M2 needs to decrypt the domain name access request to ensure the security of the system. To ensure the security of the key, the domain name access request may be decoded using a keyless scheme. Specifically, a certificate authority node M5 may be provided, and taking the certificate authority node M5 as a computer for example, the first CDN node M2 may send 502 a domain name access request to the certificate authority node M5. The certificate authority node M5 may decrypt 503 the domain name access request based on the stored private key to obtain domain name access data, and send 504 the domain name access data to the first CDN node M2, at which time the first CDN node M2 may obtain the domain name access data.

When the first CDN node provides the domain name access request to the second CDN node, the first node identifier of the first CDN node may be provided 508 to the second CDN node M3. At this time, when receiving the first node identifier and the domain name access request, the second CDN node M3 may perform access right identification on the first CDN node based on the first node identifier to obtain 509 an authentication result; if the authentication result is that the authority exists, based on the cooperative device M4 corresponding to the second CDN node, as shown in fig. 5, the cooperative device M4 may actually be a cloud server, and obtain 510 domain name configuration information corresponding to the domain name access request. Thereafter, the second CDN node M3 may send 511 the domain name configuration information to the first CDN node M2. At this time, the first CDN node M2 may obtain 512 the feedback content corresponding to the domain name access request according to the domain name configuration information provided by the second CDN node M3, and provide 513 the feedback content to the user end M1.

In order to monitor the access condition of each domain name, in some embodiments, a monitoring server may be provided, for example, the monitoring server M7 is a common server. In the foregoing embodiment, the monitoring domain name may be any one of the domain names in the domain name access request in the foregoing embodiment.

The first CDN node M2 may detect the monitoring request, obtain 515 the access data of the monitoring domain name in response to the monitoring request, and send 516 the access data to the monitoring server M7. The monitoring server M7 receives the access data, i.e. may perform monitoring analysis 517 on the access process of the monitoring domain name based on the access data to obtain a monitoring result. And judging whether the access process of the monitored domain name is abnormal or not according to the monitoring result.

In order to monitor the working condition of the first CDN node, a log node may be set to obtain access logs of a plurality of first CDN nodes. Taking the log node M8 as an ordinary server as an example, the first CDN node M2 may obtain 518 an access log corresponding to the domain name access request. The access logs are various logs generated in the domain name access request processing process. The first CDN node M2 may send an access log to the log node M8. The log node M8 may receive and save 520 the access log sent by the first CDN node M2.
