First, the noun terms to which one or more embodiments of the present application relate are explained.
RTT: round-trip Time, i.e., Round-trip delay. RTT is the interval of time from the completion of data transmission to the receipt of an acknowledgement signal.
HTTP: the hypertext Transfer Protocol (Hypertext Transfer Protocol) is a request and response standard between a client and a server. Common HTTP protocols include GET and POST methods.
In the existing CDN service, when there are multiple upstream or downstream CDN links, a GET method of an HTTP protocol is usually used to send a very small file (only a few bytes), which can only detect one RTT time from a client to a server.
Based on this, in the present application, a method for selecting a content distribution network link is provided, and the present application simultaneously relates to a device for selecting a content distribution network link, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Fig. 1 is a flowchart illustrating a method for selecting a content distribution network link, which is applied to a client according to an embodiment of the present application, and specifically includes the following steps:
step 102: and acquiring at least two content distribution network links to be selected.
In practical application, a plurality of CDN links are usually provided for a user to select, and processing requests between different CDN links are different due to the number of networks and nodes. In the method for selecting a content delivery network link provided by the present application, the best CDN link is selected from at least two CDN links to execute a service request.
Specifically, the obtaining of at least two links of the content distribution network to be selected includes:
sending a link acquisition request to a server;
and acquiring at least two links of the content distribution network to be selected, which are returned by the server in response to the link acquisition request.
In practical applications, when a user needs to upload or download data using a CDN link, a link acquisition request is usually sent to a server, where the link acquisition request is a request sent to a CDN link scheduling system of the server to acquire an available CDN link. After receiving a link acquisition request sent by the client, the server sends available CDN links to the client, and the CDN links returned by the server to the client are all CDN links to be selected.
In a specific embodiment provided by the present application, taking three candidate content distribution networks as an example, a client sends a link acquisition request to a server, and the server responds to the link acquisition request and returns a candidate content distribution network to the client: CDN-1, CDN-2, and CDN-3.
Step 104: determining service data to be transmitted, and transmitting the service data to be transmitted to a server through each content distribution network link to be selected respectively, wherein the size of the service data to be transmitted is larger than a preset threshold value.
The method includes that service data to be transmitted is test data used for detecting a CDN link to be selected, in an existing link detection method, a data package with only a few bytes is generally used for detecting round-trip delay of a line, a real use scene of a user cannot be accurately simulated, in order to simulate real uploading or downloading data of the user, the service data to be transmitted needs to have a certain volume, namely the size of the service data to be transmitted is larger than a preset threshold value, the preset threshold value can be determined according to the size of the data package in an actual data transmission process, and can also be dynamically determined according to actual conditions, for example, in actual application, when data transmission is carried out, the data is generally divided into data packages with the size of 1M for transmission, and the preset threshold value can be set to be 1M; or the preset threshold may be determined according to the data transmission record in the past preset time interval, and the value method of the preset threshold is not limited in the present application.
Preferably, the size of the service data to be transmitted may be determined according to a specific service scenario, and specifically, determining the service data to be transmitted includes:
acquiring a target service identifier;
and determining the service data to be transmitted based on the target service identification.
The target service identifier specifically refers to a specific service that needs to use a CDN link for data transmission, such as a video transmission service, an audio transmission service, and the like, and then, according to the target service identifier, corresponding service data to be transmitted can be determined, and different service identifiers can correspond to different service data to be transmitted, for example, in a video transmission scenario, the service data to be transmitted can be 3MB (megabyte); in an audio transmission scene, the service data to be transmitted may be 1 MB; in the document transmission scenario, the service data to be transmitted may be 500KB, and so on. It should be noted that, in practical application, the size and/or type of the service data to be transmitted may be determined according to the target service identifier, for example, for a video transmission scene, the service data to be transmitted may be a video file, and the size may be 5 MB; for an audio transmission scene, the service data to be transmitted can be an audio file, and the size can be 1 MB; for a document transmission scenario, the service data to be transmitted may be a text file, and the size may be 500KB, and so on.
In order to facilitate a client to quickly determine service data to be transmitted according to a target service identifier, the determining of the service data to be transmitted based on the target service identifier includes:
and determining the service data to be transmitted in a preset database according to the target service identifier.
In practical applications, the service data to be transmitted corresponding to different service identifiers may be pre-stored in a preset database, where the preset database is used to store the service identifiers and the service data to be transmitted corresponding to the service identifiers. The service data to be transmitted and the service identification are correspondingly stored in the preset database, so that the corresponding service identification to be transmitted can be quickly determined after the target service identification is determined, time delay caused by searching for the proper service identification to be transmitted is avoided, and the processing efficiency can be effectively improved.
After the service data to be transmitted are determined, the same data transmission request is used for transmitting the service data to be transmitted to the server through each CDN link, the data transmission request can be an HTTP POST request or an HTTP GET request, in order to guarantee the fairness of detecting CDN links to be selected, the same data transmission request is used for transmitting the same service data to be transmitted, detection is carried out on a plurality of CDN links to be selected concurrently, the detection data can be accelerated, and the detection efficiency is improved.
In a specific embodiment provided by the application, an audio transmission scene is taken as an example, service data D to be transmitted corresponding to the audio transmission scene is determined, wherein the size of the service data D to be transmitted is 1MB, at this time, there are 3 CDN links to be selected, and an HTTP GET request is used to transmit the service data D to be transmitted to a server through a CDN-1, a CDN-2, and a CDN-3, respectively.
Optionally, determining to-be-transmitted service data further includes:
acquiring network information of the client;
and determining the size of the service data to be transmitted according to the network information.
In practical application, determining the size of the service data to be transmitted is also related to network information of a network environment where a client is located, and determining the service data to be transmitted according to the network information where the client is located, for example, when the client is in a WIFI environment and a target service identifier is video transmission, selecting the service data to be transmitted with a larger volume to perform link detection, for example, the volume of the service data to be transmitted is 10 MB; when the client uses the cellular data and the uploaded file is small, the small service data to be transmitted can be selected for link detection, for example, the volume of the service data to be transmitted is 0.1 MB.
Step 106: and receiving response information corresponding to each to-be-selected content distribution network link returned by the server, and determining the round-trip delay of each to-be-selected content distribution network link.
In the present application, a client sends a data transmission request to a server through different CDN links, and the server also returns response information corresponding to each CDN link to the client according to the different CDN links, where in actual application, the response information may not include any content, and may also include link description information, such as information about a CND link identifier, a client IP address, a node load state, time consumed for the request, and the like, for example, the client sends service data to be transmitted to the server through a CDN-1 link, and the server returns response information corresponding to the CDN-1 to the client through the CDN-1 after receiving the service data to be transmitted, where the response information may be empty, and may include link description information related to the CDN-1, and specific content of the response information is not limited in the present application.
Round-trip Time (RTT) is a Time interval from the end of data transmission to the Time when the acknowledgment signal is received, and the lower the Round-trip Time, the faster the data transmission speed. After response information of each to-be-selected CDN link returned by the server is received, the round-trip delay of the CDN link can be determined according to the time point of sending the request by the client and the time point of receiving the response information returned by the server by the client.
In a specific embodiment provided by the application, still taking an audio transmission scene as an example, response information M-1 of the CDN-1, response information M-2 of the CDN-2, and response information M-3 of the CDN-3 returned by the server are respectively received, and then a round-trip delay corresponding to each CDN link is determined according to a sending time point of service data to be transmitted.
Step 108: and selecting a target content distribution network link from the at least two content distribution network links to be selected based on the round trip delay of each content distribution network link to be selected.
After the round-trip delay of each to-be-selected CDN link is determined, a target CDN link may be selected according to the round-trip delay of the to-be-selected CDN link, where the target CDN link is a CDN link that is finally selected for use by the method for selecting a content delivery network link provided by the present application.
In practical application, selecting a target content distribution network link from the at least two content distribution network links to be selected based on the round trip delay of each content distribution network link to be selected specifically includes:
and determining the to-be-selected content distribution network link with the shortest round trip delay as a target content distribution network link.
In practical application, the shorter the round-trip delay is, the faster the data transmission speed is, and the shorter the round-trip delay of the CND link is, the higher the quality of the CDN link is. Therefore, the CDN links with the shortest round trip delay are preferable to the target CDN link.
In a specific embodiment provided by the present application, taking three CDN links to be selected as an example, if a round-trip delay of the CDN-1 is 50ms (milliseconds), a round-trip delay of the CDN-2 is 30ms, and a round-trip delay of the CDN-3 is 68ms, it may be determined that the round-trip delay of the CDN-2 is the shortest, and then the CDN-2 is determined to be the target CDN.
In another specific embodiment provided herein, the method further comprises:
transmitting target service data to the server through the target content distribution network link;
monitoring the data transmission time of the target content distribution network link;
and under the condition that the data transmission time exceeds a preset time threshold, determining a new target content distribution network link from the content distribution network links to be selected, and transmitting the target service data through the new target content distribution network link.
In practical application, after the target CDN is determined, the service data may be transmitted through the target CDN, and in a data transmission process, a problem of a network failure or a data transmission failure caused by a node jam on a CND link often occurs, so that data transmission time of the target CDN needs to be monitored in real time, and when the data transmission time exceeds a preset time threshold, that is, when the data transmission time is overtime, it is indicated that the CDN link fails, a new target CDN link needs to be determined again in other CDN links, and the target service data is transmitted through the new CND link, thereby ensuring smooth performance of the target service.
Specifically, determining a new target content distribution network link from the candidate content distribution network links includes:
and selecting the content distribution network link with the shortest round trip delay from the content distribution network links to be selected as a new target content distribution network link.
Specifically, when the target CDN link is abnormal and cannot be used normally, a new target CDN needs to be further selected from the remaining CDN links to be selected, that is, the CDN link to be selected with the shortest round-trip delay needs to be selected as the target CDN link from the remaining CDN links to be selected.
In a specific embodiment provided by the present application, CDN-2 is selected as a target CDN link, and in a data transmission process, if a CDN-2 is abnormal, a new target CDN link needs to be selected from CDN-1 and CDN-3, and if the round-trip delay of CDN-1 is calculated as 50ms and the round-trip delay of CDN-3 is calculated as 68ms, CDN-1 is selected as the new target CDN link.
In practical application, in order to conveniently and quickly determine which CDN link has the lowest round-trip delay, service data to be transmitted may be sent to a server through each CDN link at the same time point, and then the round-trip delay of which CDN link is determined to be the lowest according to the time of response information of each CDN link received by a client, for example, the client transmits the service data to be transmitted to the server through CDN-1, CDN-2, and CDN-3 at the same time, and then, the sequence in which the client receives responses is CDN-2, CDN-1, and CDN-3, it may be determined that the round-trip delay of CDN-2 is the shortest, and CDN-2 is the best line.
It should be noted that if no response information is returned by any CDN over a preset time period, one CDN link is randomly selected as a target CDN from at least two CDN links to be selected, so as to ensure that a data transmission task can be performed smoothly.
The method for selecting the content distribution network link, which is applied to the client, comprises the following steps: acquiring at least two content distribution network links to be selected; determining service data to be transmitted, and transmitting the service data to be transmitted to a server through each content distribution network link to be selected respectively, wherein the size of the service data to be transmitted is larger than a preset threshold value; receiving response information corresponding to each content distribution network link to be selected returned by the server, and determining the round-trip delay of each content distribution network link to be selected; and selecting a target content distribution network link from the at least two content distribution network links to be selected based on the round trip delay of each content distribution network link to be selected. According to the method for selecting the content delivery network link, the real data transmission request is simulated by uploading or downloading the data to be transmitted which exceeds a certain size, and the optimal CDN link is selected more accurately by comparing the time consumed by the request of each CDN link in a round trip.
