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 described in further detail 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.
The information interaction scheme provided by the disclosure is mainly applied to the information interaction process between the central server and the node server in the Internet, and is particularly suitable for the interaction process of target data between the central server and the node server, wherein the target data is generated by the central server and is necessary data used when the node server processes a user access request. For example, the information interaction scheme may be applied to a content distribution network such as a Nginx-based network.
Fig. 1 is a schematic structural diagram of an information interaction system according to an embodiment of the present disclosure. In some embodiments, the information interaction system 100 may be implemented as, or as part of, a Nginx-based content distribution network. As shown in fig. 1, the information interaction system 100 includes a central server 110, at least one agent server 120, and a plurality of node servers 130.
The central server 110 is configured to generate target data required by the node server 130 to process the user access request; and sending a data acquisition response to the proxy server 120 in response to the data acquisition request sent by the proxy server 120. The central server 110 is a server for overall controlling the entire CDN network, and contains control policies/rules required by the CDN network, and can communicate with each proxy server 120 and each node server 130. In some embodiments, the target data is policy data for controlling network access. For example, an optimization policy to improve data access efficiency, a user filtering policy (e.g., a blacklist and whitelist policy) to determine whether a user has permission to access certain data resources, etc.
The proxy server 120 is in communication connection with the central server 110 and the node server 130, and is configured to send a data acquisition request to the central server 110 when the proxy server 120 is monitored to meet a preset condition; receiving a data acquisition response sent by the central server 110, wherein the data acquisition response comprises target data; and sending a data storage request to the node server 130, where the data storage request includes the target data.
The preset condition is a preset condition for triggering the proxy server 120 to send a data acquisition request to the central server 110. In some embodiments, the preset condition includes at least one of arrival of a timing period, completion of a preset event, and reception of an externally transmitted trigger signal. In this embodiment, the data acquisition request may be sent at a fixed time, or sent when the execution of a preset early event is completed, or sent when a trigger signal sent from the outside is received. In some embodiments, the timing period is determined based on the update frequency of the target data in the central server 110. For example, the timing period is set to be consistent with the update frequency of the target data in the central server 110; alternatively, a timing period with a shorter/longer duration is set according to the speed/slowness of the update frequency of the target data in the central server 110. In this way, the probability of duplication between the target data requested from the central server 110 by the proxy server 120 is reduced each time, so as to reduce the redundancy of the target data and reduce the data acquisition operation of the duplicated data by the proxy server 120.
In some embodiments, the proxy server 120 sends a data storage request to the node server 130 after detecting the target data update. In this embodiment, the proxy server 120 does not acquire the target data and then send it to the node server 130, but needs to first detect whether the target data is updated compared with the previously acquired target data. Only if an update is detected, the target data is packaged in a data storage request and sent to the node server 130. Therefore, the target data acquired by the node server 130 is not repeated, the data redundancy degree is further reduced, and the operation that the node server 130 repeatedly stores the data is further reduced.
And the node server 130 is used for responding to the data storage request and storing the target data. The node server 130 is a server in the CDN network that directly interacts with the user terminal, and receives and processes a user access request sent by the client terminal. Moreover, when the node server 130 processes the user access request, the policy/rule generated by the central server and used for controlling the user to access the CDN network needs to be executed first, so that the target data needs to be obtained first. In the embodiment of the present disclosure, the node server 130 obtains the target data through the data storage request sent by the proxy server 120, and needs to store the obtained target data in the local storage space. In some embodiments, the data storage request further includes storage location information, which is used to determine that the storage location of the target data in the node server 130 is an Nginx shared memory or cache server.
In some embodiments, the information interaction system 100 comprises a proxy server 120, and the proxy server 120 sends the target data to a plurality of node servers 130. In some embodiments, the information interaction system 100 includes a plurality of proxy servers 120, and the number of the proxy servers 120 is less than the number of the node servers 130. In this embodiment, part of the proxy servers 120 and the node servers 130 have a one-to-one relationship, and part of the proxy servers 120 and the node servers 130 have a one-to-many relationship. In some embodiments, the number of proxy servers 120 is consistent with the number of node servers 130. In this embodiment, the proxy server 120 and the node server 130 have a one-to-one correspondence relationship. Therefore, the proxy server 120 only forwards the target data for the corresponding node server 130, thereby reducing the service complexity of the proxy server, improving the efficiency of the proxy server for acquiring and sending the target data, and enabling the node server to acquire the updated target data more timely.
Referring to fig. 2, taking an interaction process among a node server 130, an agent server 120 and a central server 110 in the information interaction system 100 as an example, the information interaction process of the information interaction system 100 is as follows:
s1, when monitoring that the proxy server 120 meets the preset condition, sending a data acquisition request to the central server 110. The data acquisition request is used to request target data from the central server 110.
S2, after receiving the data obtaining request, the central server 110 feeds back a data obtaining response containing the target data to the proxy server 120.
S3, after receiving the data obtaining response, the proxy server 120 sends a data storage request to the node server 130. The data storage request is used to request the node server 130 to store the target data, so the data storage request includes the target data.
S4, after receiving the data storage request, the node server 130 stores the target data in the data storage request into a local storage space of the node server. In some embodiments, the data storage request carries storage location information, and the node server 130 stores the target data in the nginnx shared memory or the cache server according to the storage location information.
S5, when the node server 130 receives the user access request, it may query the target data from the Nginx shared memory or the cache server, and process the user access request and feed back a processing response based on the target data, without synchronously requesting data from the central server 110, thereby avoiding strong coupling between the central server and the service requirement, and reducing the complexity of the system.
Fig. 3 is a flowchart of an information interaction method applied to a proxy server according to an embodiment of the present disclosure. The information interaction method applied to the agent server can be executed by an information interaction device configured at the agent server, and the device can be implemented by software and/or hardware, and the device can be integrated in electronic equipment, such as a desktop computer, a server or a super computer. Referring to fig. 3, the information interaction method applied to the proxy server specifically includes:
and S110, sending a data acquisition request to the central server when the agent server is monitored to meet the preset conditions.
The preset condition is a preset condition used for triggering the sending of the data acquisition request to the central server. In some embodiments, the preset condition includes at least one of arrival of a timing period, completion of a preset event, and reception of an externally transmitted trigger signal. In this embodiment, the data acquisition request may be sent at a fixed time, or sent when the execution of a preset early event is completed, or sent when a trigger signal sent from the outside is received. In some embodiments, the timing period is determined based on an update frequency of the target data in the central server. For example, the timing period is set to be consistent with the updating frequency of the target data in the central server; or, setting a timing cycle with shorter/longer duration according to the speed/slow of the update frequency of the target data in the central server. Therefore, the proxy server side can send out the data acquisition request at a more proper time, and reduce the repetition rate between the subsequently acquired target data and the previously acquired target data, thereby reducing the redundancy degree of the target data.
Specifically, the agent server sends a data acquisition request to the central server when monitoring that the preset condition is met, so as to actively and asynchronously pull the target data from the central server with the user access request.
And S120, receiving a data acquisition response sent by the central server, wherein the data acquisition response comprises target data required by the node server to process the user access request.
Wherein the data acquisition response is a result obtained after processing the data acquisition request. For example, if the data fetch request is for requesting target data, then the data fetch response includes the target data when the target data is present. In some embodiments, the target data is policy data for controlling network access. For example, the target data may be an optimization policy that improves data access efficiency, a user filtering policy (e.g., a blacklist and whitelist policy) that indicates whether a user has permission to access certain data resources, and the like.
Specifically, the central server sends a data acquisition response containing the target data to the proxy server in response to the data acquisition request of the proxy server, and then the proxy server receives the data acquisition response sent by the central server.
S130, sending a data storage request to the node server, wherein the data storage request comprises target data and is used for requesting the node server to store the target data.
Specifically, after acquiring the target data, the proxy server may send a data storage request including the target data to one or more node servers corresponding to the proxy server. The data storage request is a request for triggering the node server to receive and store target data, and may be an http request for requesting data writing, for example. And the node server side receiving the data storage request stores the target data into the local storage space.
In some embodiments, sending the data storage request to the node server comprises: and if the target data update is detected, sending a data storage request to the node server. In this embodiment, after the proxy server acquires the target data, it first detects whether the target data is updated compared with the previously acquired target data. If not, the data storage request does not need to be sent to the corresponding node server. And if the data is updated, packaging the target data in the data storage request and sending the data to the corresponding node server. Therefore, target data acquired by the node server cannot be repeated, the data redundancy degree is further reduced, and the operation that the node server repeatedly stores the same data is further reduced.
In some embodiments, the data storage request further includes storage location information, where the storage location information is used to determine that the storage location of the target data in the node server is an nginn shared memory or a cache server. The storage location information is information capable of determining a specific storage location of the data, and for example, for the nginn shared memory, the storage location information may be domain name information carried in an http request. The position of the target data stored by the designated node server side in the storage position information can be set by self based on the service scene and the service requirement.
According to the technical scheme of the embodiment of the disclosure, the data acquisition request is sent to the central server when the proxy server meets the preset condition so as to request the central server for the target data required by the node server to process the user access request, and after the target data is obtained, the target data is sent to the node server so that the node server can store the target data to the local. Therefore, the proxy server can be used as a transfer terminal for target data interaction between the central server and the node server, the node server can acquire target data asynchronously in processing the user access request, and the service processing complexity of the node server is reduced, so that the processing efficiency of the node server on the user access request is improved, and the time for waiting for user access is reduced. And the proxy server can pull the target data from the central server only when the preset conditions are met, so that the redundancy of the target data in the node server is avoided to a certain extent.
Fig. 4 is a flowchart of an information interaction method applied to a node server according to an embodiment of the present disclosure. The information interaction method applied to the node server can be executed by an information interaction device configured at the node server, where the information interaction device can be implemented by software and/or hardware, and the information interaction device can be integrated in an electronic device, such as a desktop computer, a server, or a super computer. The same terms or steps as those in the above embodiments can be referred to in the above embodiments, and are not described herein. Referring to fig. 4, the information interaction method applied to the node server specifically includes:
s210, receiving a data storage request sent by the proxy server, wherein the data storage request comprises target data required by the node server to process the user access request, and the target data is data acquired from the central server when the proxy server meets preset conditions.
Specifically, the proxy server is only used as a transfer terminal of the target data, and after acquiring the target data, the proxy server actively sends the target data to the node server under a certain condition. The node server receives a data storage request containing target data sent by the proxy server.
And S220, storing the target data.
Specifically, the node server obtains the target data and information related to the target data storage by parsing the data storage request. And storing the target data into the local storage space thereof according to the storage-related information.
In some embodiments, storing the target data comprises: and if the data storage request comprises storage position information corresponding to the Nginx shared memory, packaging target data according to a preset data structure, and storing the packaged target data into the Nginx shared memory. If the data storage request is an http request and carries storage location information (such as an internal domain name) corresponding to the Nginx shared memory, the node server encapsulates the target data according to a storage structure (i.e., a preset data structure, such as a specific array format) of the data in the Nginx shared memory. And then, injecting the encapsulated target data into the Nginx shared memory through an 80 port of the internal domain name. Therefore, the memory utilization rate of Nginx can be reduced to a great extent, the access efficiency of the target data is ensured, and the processing performance of the node server-side on the business related to the target data is improved.
In some embodiments, storing the target data comprises: and if the data storage request contains storage position information corresponding to the cache server, storing the target data to the cache server. And if the data storage request contains storage position information corresponding to the cache server, the node server stores the target data into the cache server inside the node server. For example, it may be stored in a database of the cache server through the virtual file system. Therefore, the target data can act on various online service businesses in the node server, and the utilization rate of the target data is improved.
In some embodiments, the information interaction method applied to the node server further includes: receiving a user access request sent by a client; inquiring and acquiring target data from the Nginx shared memory or the cache server; and processing the user access request based on the target data, and feeding back a processing result to the client. In this embodiment, the node server has stored the target data in the Nginx shared memory or the cache server. When receiving a user access request sent by a client, the target data required can be inquired from the Nginx shared memory or the cache server. Then, the user access request is processed based on the target data, and the processing result is fed back to the client as the response of the client to the user access request. Therefore, synchronous request data from the central server side in the process of processing the user access request can be avoided, the strong coupling of the acquisition process of the target data and the service requirement is weakened, and the complexity of the system is reduced.
According to the technical scheme of the embodiment of the disclosure, the node server acquires and stores the target data by receiving the data storage request sent by the proxy server, so that the node server relies on the proxy server to asynchronously acquire the target data, strong coupling between the node server and the user access request is avoided, the processing efficiency of the user access request is improved, the waiting time for user access is reduced, and the user experience is improved.
