To solve the problems in the background art, embodiments of the present disclosure provide a method and an apparatus for scheduling network resource requests when the network resource requests suddenly increase. Specifically, the CDN cache server may detect a network bandwidth occupation amount of itself, and redirect the received network resource request to the CDN cache server in the CDN node where the network bandwidth occupation amount is lower than a preset network bandwidth occupation threshold if the network bandwidth occupation amount of itself is detected to be higher than or equal to the preset network bandwidth occupation threshold, so that it is ensured that the network bandwidth of the CDN cache server is not filled under an extreme condition of sudden increase of the network resource request, and the CDN service quality is ensured.
The following describes in detail a network resource request scheduling method, apparatus, device, and storage medium provided in the embodiments of the present disclosure with specific embodiments in conjunction with the accompanying drawings.
FIG. 1 illustrates a schematic diagram of an exemplary operating environment in which embodiments of the present disclosure can be implemented, as shown in FIG. 1, operating environment 100 may include: the system comprises a user terminal, a CDN cache server and CDN scheduling equipment.
The user terminal may be a mobile electronic device or a non-mobile electronic device. For example, the Mobile electronic device may be a Mobile phone, a tablet Computer, a notebook Computer, a palmtop Computer, an Ultra-Mobile Personal Computer (UMPC), or the like, and the non-Mobile electronic device may be a Personal Computer (PC), a super Computer, a smart television, or the like.
The CDN cache server is a server in a CDN cache node, and is used to cache resources such as pictures, music, videos, files in a website (e.g., html files, css files, js files), and software installation packages. It can be known that a plurality of CDN cache servers may be deployed in the CDN cache node.
The CDN scheduling device is a Load balancing device in the CDN, such as a Global Server Load Balance (GSLB).
As an example, the CDN cache server detects the network bandwidth occupation amount of itself in real time, and if it is detected that the network bandwidth occupation amount of itself is higher than or equal to a preset network bandwidth occupation threshold, determines a CDN cache server in which the network bandwidth occupation amount is lower than the preset network bandwidth occupation threshold in the CDN node to which the network bandwidth occupation amount of the CDN cache server belongs according to the network bandwidth occupation amounts of other CDN cache servers in the CDN node to which the CDN cache server is obtained from the CDN scheduling device, and redirects a network resource request sent by the user terminal to the CDN cache server in which the network bandwidth occupation amount is lower than the preset network bandwidth occupation threshold in the CDN node to which the network bandwidth occupation amount is lower. Therefore, the network bandwidth of the CDN cache server can be ensured not to be filled under the extreme condition that the network resource request is suddenly increased, and the CDN service quality is ensured.
Fig. 2 shows a flowchart of a network resource request scheduling method in sudden increase of network resource requests according to an embodiment of the present disclosure, and as shown in fig. 2, the network resource request scheduling method 200 may include the following steps:
s210, the user terminal sends a network resource request to the CDN cache server.
The network resource request is used for requesting resources such as pictures, music, videos, files (html, css, js) in a website, and software installation packages, and is not limited herein.
It should be noted that before sending the network resource request, the CDN scheduling device needs to select the CDN cache server according to the load balancing policy.
And S220, the CDN cache server receives the network resource request, detects the occupied amount of the network bandwidth in real time and improves the detection accuracy.
The network bandwidth occupation amount may refer to a ratio of the used network bandwidth to the total network bandwidth or the upper limit network bandwidth, or may refer to how much network bandwidth is used.
And S230, if the network bandwidth occupation amount is detected to be higher than or equal to a preset network bandwidth occupation threshold, the CDN cache server sends a network bandwidth occupation amount request to the CDN scheduling equipment.
Illustratively, the preset network bandwidth occupation threshold may be 95%, 90%, 85%, etc. of the total network bandwidth or the upper limit network bandwidth, and the network bandwidth occupation request may be sent in real time or at regular time, which is not limited herein.
And S240, the CDN scheduling device receives the network bandwidth occupation amount request, responds to the network bandwidth occupation amount request, and sends the network bandwidth occupation amount reported by other CDN cache servers in the CDN node to the CDN cache server.
In some embodiments, each CDN cache server in the CDN node may report the network bandwidth occupation amount of itself to the CDN scheduling device in real time by calling the HTTP interface.
And S250, the CDN cache server receives the network bandwidth occupation amount of other CDN cache servers, and determines the CDN cache server of which the network bandwidth occupation amount is lower than a preset network bandwidth occupation threshold value in the CDN node according to the received network bandwidth occupation amount of other CDN cache servers.
As an example, each CDN cache server in the CDN node may set a corresponding preset network bandwidth occupation threshold, respectively, so as to fully utilize the bandwidth of each CDN cache server.
For example, a preset network bandwidth occupation threshold corresponding to each CDN cache server in the CDN node may be configured in the CDN scheduling device, and then the CDN cache server may obtain the preset network bandwidth occupation threshold corresponding to each CDN cache server in the CDN node from the CDN scheduling device in advance.
And S260, the CDN cache server redirects the received network resource request to a CDN cache server of which the network bandwidth occupation amount is lower than a preset network bandwidth occupation threshold value in the CDN node.
In some embodiments, the CDN cache server may select a CDN cache server that meets a preset condition from CDN cache servers in which the network bandwidth occupation amount of the CDN node is lower than a preset network bandwidth occupation threshold.
The preset condition can be that the occupied amount of the network bandwidth is minimum; or the difference between the network bandwidth occupation amount and the preset network bandwidth occupation threshold is the largest, and no limitation is made here.
And then sending a redirection instruction to the user terminal so that the user terminal can quickly send a network resource request to the selected CDN cache server according to the redirection instruction.
Specifically, a redirection instruction may be sent to the user terminal according to the IP address of the selected CDN cache server, so that the user terminal sends the network resource request to the selected CDN cache server according to the IP address in the redirection instruction.
And sending a redirection instruction to the user terminal through the CDN scheduling device according to the IP address of the selected CDN cache server, so that the user terminal sends a network resource request to the selected CDN cache server according to the IP address in the redirection instruction.
Alternatively, the redirect instruction may be an HTTP 302 instruction, without limitation.
According to the embodiment of the disclosure, the CDN cache server may detect a network bandwidth occupation amount of itself, and redirect the received network resource request to the CDN cache server in the CDN node to which the network bandwidth occupation amount is lower than a preset network bandwidth occupation threshold if the network bandwidth occupation amount of itself is detected to be higher than or equal to the preset network bandwidth occupation threshold, so that it may be ensured that the network bandwidth of the CDN cache server is not filled under an extreme condition of sudden increase of the network resource request, and the CDN service quality is ensured.
In some embodiments, in order to further avoid that the CDN cache server is full of network bandwidth to affect the quality of service, after the received network resource request is redirected to another CDN cache server, the CDN cache server may further send a redirection record of the network resource request to the CDN scheduling device, and notify the CDN scheduling device to stop allocating the network resource request to the CDN cache server until the network bandwidth occupancy uploaded by the CDN cache server is lower than a preset network bandwidth occupancy threshold.
It should be noted that, if the network bandwidth occupation amount of the CDN cache server is lower than the preset network bandwidth occupation threshold, the CDN scheduling device reallocates the network resource request to the CDN cache server, and the CDN cache server processes the network resource request normally, and does not redirect.
In other embodiments, if the network bandwidth occupation amounts of other CDN cache servers in the CDN node are all higher than or equal to the preset network bandwidth occupation threshold, the CDN cache servers may redirect the received network resource request to a CDN cache server in the corresponding backup node, so as to further ensure that the network bandwidth of the CDN cache server is not filled.
The following may explain the network resource request scheduling method provided by the present disclosure in detail with reference to a specific embodiment, specifically as follows:
suppose that 5 CDN cache servers, namely a server 1, a server 2, a server 3, a server 4, and a server 5, exist in a certain CDN node, and each server detects its own network bandwidth occupation amount in real time and regularly acquires the network bandwidth occupation amounts reported by other servers from a CDN scheduling device.
If the server 1 detects that the current network bandwidth occupation amount of the server 1 is 96% and is higher than a corresponding preset network bandwidth occupation threshold value (95%), it is determined that the network bandwidth occupation amount of the server 1 is too high and is unavailable at the moment, and the server needs to be selected to process the network resource request instead.
Suppose that the network bandwidth occupation amount of the server 2, the network bandwidth occupation amount of the server 3, the network bandwidth occupation amount of the server 4 and the network bandwidth occupation amount of the server 5, which are acquired by the server 1 from the CDN scheduling device, are 80%, 75%, 65% and 97%. The preset network bandwidth occupation threshold corresponding to the server 2 is 90%, the preset network bandwidth occupation threshold corresponding to the server 3 is 95%, the preset network bandwidth occupation threshold corresponding to the server 4 is 80%, and the preset network bandwidth occupation threshold corresponding to the server 5 is 95%.
At this time, the server 1 may determine that the server 2, the server 3, and the server 4 are respectively lower than the respective corresponding preset network bandwidth occupation thresholds, and respectively calculate the difference between the respective network bandwidth occupation amounts of the server 2, the server 3, and the server 4 and the preset network bandwidth occupation thresholds, and calculate that the difference corresponding to the server 2 is 10%, the difference corresponding to the server 3 is 20%, and the difference corresponding to the server 4 is 15%, so that the server 3 with the largest difference may be selected to process the network resource request received by itself.
Next, the server 1 redirects the received network resource request to the server 3, sends a redirection record of the network resource request to the CDN scheduling device, and notifies the CDN scheduling device to stop allocating the network resource request to the server 1 until the occupied amount of the network bandwidth uploaded by the CDN cache server is lower than a preset network bandwidth occupation threshold, so that it can be ensured that the network bandwidth of the CDN cache server is not filled under an extreme condition of sudden increase of the network resource request, and the quality of service of the CDN is ensured.
