In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 2, fig. 2 is a first embodiment of a method for obtaining the content of the present invention, the method includes the following steps:
step S10, receiving a content acquisition request scheduled by a scheduling node, wherein the content acquisition request is sent to the scheduling node by a terminal.
In this embodiment, when receiving a content acquisition request sent by a terminal, the scheduling node responds to the terminal with a 302 status code to an edge node address, and then the terminal sends the content acquisition request to the edge node according to the edge website address. The content acquiring method of the present embodiment is applied to an edge node of a content delivery network, where the Content Delivery Network (CDN) includes a scheduling node and an edge node, and the CDN is generally called Content Delivery Network, i.e., the content delivery network. The basic idea is to avoid the bottleneck and link on the internet which possibly affects the data transmission speed and stability as much as possible, so that the content transmission is faster and more stable. Through a layer of intelligent virtual network formed by node servers placed everywhere in the network and based on the existing internet, the CDN system can redirect the user's request to the service node nearest to the user in real time according to the network flow and the comprehensive information of the connection of each node, the load condition, the distance to the user, the response time and the like. 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. Further, the scheduling node is configured to receive a content acquisition request sent by the terminal and schedule the content acquisition request to the edge node, so that the edge node responds to the content acquisition request sent by the terminal, specifically, as long as a domain name of a request address (URL) of the content acquisition request uses a domain name of the scheduling node, the content acquisition request must be requested to the scheduling node, the scheduling node will schedule the address to the edge node, and then the edge node processes the request.
And step S20, generating a source return request according to the content acquisition request.
In this embodiment, the edge node generates a corresponding source-returning request when receiving a content acquisition request scheduled by the scheduling node.
And step S30, the source returning request is sent to a source station corresponding to the request address and the content type of the content acquisition request, wherein the source station responds to the source returning request and sends target content.
In this embodiment, the selectable source station is determined based on the request address, and then the source station to be transmitted is further determined based on the requested and content types of the content acquisition request, specifically, the content types are obtained by analyzing the content acquisition request, and can be classified according to the content types, the source stations which are not available are selected according to the different content types to process the source return request, and the main content types currently include: the on-demand, live broadcast, time shifting and review can dynamically configure different content types according to the requirements; when the source station to be returned is determined according to the request address, a source return request can be generated and sent to the corresponding source station; when the source station receives a source returning request sent by the edge node, the source station sends target content to the edge node so that the edge node receives the target content.
Alternatively, for the content type, by taking the on-demand content type and the live content type as examples, different source stations may be used for the on-demand content type and the live content type, so that the on-demand content and the live content are isolated (the isolation is that the on-demand content and the live content are not associated at all, and are not required to be on-demand or live respectively as one piece cdn, but the same cdn may be used, and are not associated with each other). Further, the same type of content may also have multiple source stations, such as: 3 source stations can be configured for the content type of the on-demand, the 1 st source return request returns to the on-demand source station 1, and the 2 nd source return request returns to the source station 2, so that the pressure of the source stations of the same type can be reduced. And if one of the source stations is down, the on-demand content can still return to the source without affecting the service.
Alternatively, if the discovery rule is not its own rule when processing the content acquisition request, it may be considered as a third party integrated source station address, and then the source request is directly generated and sent back to the third party source station. Specifically, whether the rule of the content acquisition request is a third party rule is determined; when the rule of the content acquisition request is a third party rule, fuzzy matching is performed according to the request address of the content acquisition request to determine a third party source station matched with the character of the request address, and optionally, the third party source station with similar characters is searched according to the request address to serve as the source station address of the return source, for example: the request address of the third party source station is provided with a fixed character, and whether the third party source station address is supported can be judged only by matching the character; after determining that the source station address of the third-party source station is searched, sending a source returning request to the third-party source station so that the third-party source station sends target content to the edge node, and then the edge node sends the target content to the terminal. And when the rule of the content acquisition request is not a third party rule, executing the step of sending the back source request to the source station corresponding to the request address and the content type of the content acquisition request. For the determination of the third party rule, the content acquisition request can be analyzed, whether the preset parameters are contained or not is then determined, if the preset parameters are contained, the content acquisition request is processed as the content acquisition request of the non-third party rule, and if the preset parameters are contained, the content acquisition request is processed as the content acquisition request of the third party rule; further, the corresponding parameter information can be obtained by analyzing the content acquisition request, and the parameter information mainly comprises: content ID, content type, content protocol, device MAC address, public network IP, token, validity time.
In the technical solution of this embodiment, the edge node may process a content acquisition request with a preset rule, or may process a content acquisition request with a non-preset rule, where the non-preset rule includes a third party rule, and by setting a disposition manner of the content acquisition request with a different rule, may process content acquisition requests with multiple different rules, and may process preset rules for content acquisition.
And step S40, the received target content is sent to the terminal.
In this embodiment, after receiving the target content, the edge node sends the target content to the terminal, and specifically, sends the parameter information obtained according to the analysis content acquisition request to the corresponding terminal.
Optionally, after the target content is obtained, the target content is stored locally.
Optionally, when the edge node receives the content acquisition request, whether the target content is stored is queried locally in advance according to the content acquisition request; if the target content is locally available, the target content is sent to a terminal; and if the target content is not stored locally, executing the step of generating a source returning request according to the content acquisition request.
In the technical scheme of the embodiment, when the content acquisition request is received, whether the target content for response is locally stored is determined, if the target content is locally stored, the generation and the transmission of the back source request can be canceled, the content acquisition request is directly responded, and the calculation force required by the back source is reduced.
In this embodiment, since the edge node may receive and determine the content type of the target content to be acquired according to the content acquisition request, when there are multiple source stations corresponding to the request address carried by the content acquisition request, if source returning is to be performed, after the source returning request is generated, the corresponding source station may be determined in the source stations corresponding to the request address according to the content type of the target content to be acquired, and the source returning request is sent to the corresponding source station, so that data sent by the source station is received to respond to the content acquisition request sent by the terminal, so that efficiency of the source station for processing the source returning request is improved, and thus content acquisition efficiency is improved.
Referring to fig. 3, fig. 3 is a second embodiment of the method for obtaining the content of the present invention, based on the first embodiment, step S30 includes:
step S31, determining the number of source stations corresponding to the request address and the content type.
And step S32, when the number of the source stations is larger than 1, the source returning request is sent to the source station corresponding to the request address according to the working state of each source station.
In this embodiment, if the number of optional source stations determined based on the request address and the content type is any multiple, the screening of the source stations may be further performed based on the working states of the optional source stations.
And step S33, when the number of the source stations is 1, the source returning request is sent to the source station corresponding to the request address.
In the technical scheme of the embodiment, after the request address and the content type determine a plurality of optional source stations, the source returning request can be normally processed, and the source station for processing the source returning request is selected according to the working state of the source station, so that the stability of content acquisition is improved.
Referring to fig. 4, fig. 4 is a third embodiment of the method for obtaining the content of the present invention, based on any one of the first to second embodiments, step S32 includes:
and S321, when the number of the source stations is larger than 1, determining the working state of each source station corresponding to the request address.
And step S322, when the working state of the source station is an idle state, the source returning request is sent to the source station in the idle state.
In the technical scheme of the embodiment, after the request address and the content type determine a plurality of optional source stations, when an idle source station exists, the source station which is endangered to crash can be prevented from being selected to process the source returning request, and the possibility of source returning abnormality is reduced.
Referring to fig. 5, fig. 5 is a fourth embodiment of the method for obtaining the content of the present invention, based on any one of the first to third embodiments, after step S322, further including:
step S323, when the working states of the source stations are all busy states, returning to execute the step of determining the number of source stations corresponding to the request address and the content type.
In this embodiment, when the source station that processes the source return request is selected according to the working state of the source station, if the source stations that are suitable for processing the source return request are all busy states, the step of determining the number of source stations corresponding to the request address and the content type may be performed in a return manner, so as to wait for the source stations in an idle state to appear, and then send the source return request to the corresponding source station.
In the technical scheme of the embodiment, through the technical characteristics, whether the source returning request cannot be processed due to the busy source station can be determined, if so, the source returning is not directly abandoned, and the processing opportunity is waited, and the embodiment can improve the processing success rate of the source returning request.
