The CDN generally includes an edge node, an upper node, and a source station node, and the CDN-based live video service system may further include a scheduling center node.
For example, referring to fig. 1, when a user selects to view a live video (which may be referred to as a target live video) in a client, the client may send a pull stream request for the target live video to an edge node (which may be referred to as a target edge node) in the CDN. After receiving the pull request, the target edge node may forward the pull request to the dispatch center node. The scheduling center node may notify the target edge node back to the source of the node in the upper layer. Then, the target edge node may perform domain name resolution on the domain name carried in the pull request to obtain address information of a corresponding upper node (i.e., a target upper node), and establish network connection with the target upper node according to the address information obtained by the resolution, and further send the pull request to the target upper node through the established network connection.
The target upper node can perform domain name resolution on a domain name carried in the pull stream request to obtain address information of the target source station node, and establishes network connection with the target source station node according to the address information obtained through resolution, and further sends the pull stream request to the target source station node through the established network connection to request to acquire video data of the target live broadcast video.

The above process takes a long time, which results in a long time delay for the client to acquire the video data, and affects the viewing experience of the user.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, domain name resolution needs to be performed sequentially through a target edge node, the target edge node establishes network connection with a target upper node, the target upper node performs domain name resolution, the target upper node establishes network connection with a target source station node, and then the target source station node can receive a pull flow request. The above process takes a long time, which results in a long time delay for the client to acquire the video data, and affects the viewing experience of the user.
In order to solve the above problem, an embodiment of the present application provides a system for processing a pull request, which may include a scheduling center node and a target edge node in a networking shown in fig. 2, where:
and the target edge node is used for sending a pull stream request to the dispatching center node if receiving the pull stream request aiming at the target live broadcast video sent by the client.
The dispatching center node is used for receiving the pull flow request; based on the target live broadcast video, a stream pulling request is sent to a target upper layer node corresponding to the target edge node, and a first reminding message is sent to the target edge node.
And the target edge node is also used for sending a stream pulling request to the target upper node if the first reminding message is received.
Based on the processing system for the pull stream request provided by the embodiment of the application, when the scheduling center node sends the first reminding message to the target edge node, the pull stream request can also be sent to the target upper node at the same time, that is, before the target edge node sends the pull stream request to the target upper node, the target upper node can receive the pull stream request sent by the scheduling center node, and can shorten the time for the target upper node to receive the pull stream request, and further, the time for the target source station node to receive the pull stream request can be shortened, accordingly, the time delay for the client to obtain the video data can be reduced, and the viewing experience of the user can be improved.
With regard to other embodiments of the above-described system, reference may be made to the following detailed description of method embodiments for scheduling a hub node and a target edge node.
Referring to fig. 3, fig. 3 is a flowchart of a method for processing a pull request applied to a scheduling center node according to an embodiment of the present application, where the scheduling center node may be a scheduling center node in the pull request processing system, and the method may include the following steps:
s301: and receiving a pull stream request aiming at the target live video sent by the target edge node.
S302: based on the target live broadcast video, sending a pull stream request to a target upper node corresponding to the target edge node, and sending a first reminding message to the target edge node, so that the target edge node sends the pull stream request to the target upper node after receiving the first reminding message.
Based on the method for processing the pull request provided by the embodiment of the application, when the scheduling center node sends the first reminding message to the target edge node, the pull request can be sent to the target upper node at the same time, that is, before the target edge node sends the pull request to the target upper node, the target upper node can receive the pull request sent by the scheduling center node, and can shorten the time for the target upper node to receive the pull request, so that the time for the target source station node to receive the pull request can be shortened, correspondingly, the time delay for the client to obtain the video data can be reduced, and the viewing experience of the user can be improved.
For step S301, the edge node may be a node close to the user side in the CDN, and is configured to directly receive a pull request sent by the client. The target edge node may be any edge node in the CDN.
The scheduling center node is used for controlling the flow of the node in the CDN, and may communicate with the node in the CDN.
The pull stream request for the target live video may carry a domain name and a stream identifier. The domain name is used for identifying a provider to which the target live video belongs, and the stream identification is used for identifying the anchor.
For example, if the target live video is a video that the anchor X of the live platform a is currently playing, the domain name carried in the pull stream request is the domain name corresponding to the live platform a, and the stream identifier carried in the pull stream request corresponds to the live room of the anchor X.
In step S302, after receiving the pull request sent by the target edge node, the scheduling center node may notify the target edge node to return to the source (i.e., send the pull request to the target upper node) to request to obtain video data of the target live video. Meanwhile, the dispatching center node can also directly send a pull flow request to the target upper node.
In an implementation manner, the scheduling center node may locally record a corresponding relationship between the edge node and an upper node, and the scheduling center node may directly determine a target upper node corresponding to the target edge node without performing domain name resolution, and send a pull request to the target upper node, thereby shortening the time for the target upper node to receive the pull request.
Based on the above processing, before the target edge node sends the pull stream request to the target upper node, the target upper node has received the pull stream request, so that the time for the target upper node to receive the pull stream request is shortened, accordingly, the time for the target source station node to receive the pull stream request can be shortened, the time delay for the client to obtain the video data is reduced, and the viewing experience of the user is improved.
In one embodiment, referring to fig. 4, before step S302, the method may further include the steps of:
s303: and judging whether other edge nodes except the target edge node cache the target video data of the target live broadcast video.
Accordingly, S302 may include:
s3021: and under the condition that other edge nodes except the target edge node do not cache target video data, sending a stream pulling request to a target upper layer node corresponding to the target edge node based on the target live broadcast video, and sending a first reminding message to the target edge node.
In one implementation, the scheduling center node may determine video data cached in each edge node in the CDN. Therefore, when a stream pulling request for the target live video is received, the scheduling center node can determine whether other edge nodes except the target edge node cache the target video data of the target live video.
For example, the scheduling center node may determine whether a pull request for a target live video, which is sent by another edge node, is received before the current time.
If so, it indicates that there is another edge node that requested the target video data of the target live video before, that is, the other edge node caches the target video data.
If not, it indicates that no other edge node has requested the target video data before.
Furthermore, under the condition that no other edge node requests the target video data before, the scheduling center node may send a pull stream request to the target upper node and send a first reminding message to the target edge node.
In one embodiment, in order to further reduce the time delay of the client for acquiring the video data and improve the viewing experience of the user, the method may further include the following steps:
and if the other edge nodes except the target edge node cache the target video data, sending a second reminding message to the target edge node so that the target edge node requests the target video data from the other edge nodes.
In this embodiment of the application, if other edge nodes except the target edge node cache the target video data, that is, before receiving the pull stream request sent by the target edge node, the scheduling center node has received the pull stream request for the target live video sent by the other edge nodes.
Correspondingly, the scheduling center node may determine the other edge nodes, and send a second warning message to the target edge node, where the second warning message may carry address information of the other edge nodes.
The address information of the node mentioned in the embodiment of the present application may be an IP (Internet Protocol) address of the node.
Further, after receiving the second reminding message, the target edge node may send a request message for the target live video to the other edge nodes to obtain the target video data.
Based on the processing, the target edge node does not need to request the upper-layer node, and can directly acquire the target video data from other edge nodes, so that the time delay of the client for acquiring the video data can be further reduced, and the watching experience of the user is improved.
In an embodiment, the local record of the scheduling center node may have a corresponding relationship between a live video, an edge node and an upper node, and accordingly, before step S302, the method may further include the following steps:

Based on the above processing, before the target edge node sends the pull request to the target upper node, the target upper node already receives the pull request, and the time for the target upper node to receive the pull request is shortened. In addition, before the target upper node sends the stream pulling request to the target source station node, the target source station node already receives the stream pulling request, so that the target source station node can load the target video data in advance, and further, when the stream pulling request sent by the target upper node is received, the target source station node can directly return the target video data to the target upper node, thereby reducing the time delay of the client for obtaining the video data and improving the viewing experience of the user.

The first reminding message is sent to the target edge node when the dispatching center node sends the pull flow request to the target upper node.
Therefore, when the scheduling center node sends the first reminding message to the target edge node, the scheduling center node can also send a pull request to the target upper node at the same time, so that before the target edge node sends the pull request to the target upper node, the target upper node can receive the pull request sent by the scheduling center node, the time for the target upper node to receive the pull request can be shortened, the time for the target source station node to receive the pull request can be further shortened, correspondingly, the time delay for the client to obtain the video data can be reduced, and the viewing experience of the user can be improved.

Step 2: and if a first reminding message sent by the dispatching center node according to the pull flow request is received, extracting the address information of the target upper node from the first reminding message.
In one implementation, after receiving the first prompting message, the target edge node may perform domain name resolution on a domain name carried in the pull request to obtain address information of the target upper node.
In an implementation manner, the first reminding message may also carry address information of a target upper node, and correspondingly, the target edge node may directly extract the address information of the target upper node from the first reminding message, so as to save time for domain name resolution, further shorten time for the target upper node to receive a pull request, and further shorten time for the target source station node to receive the pull request.
In one embodiment, after step S501, the method may further include the steps of:
and if a second reminding message sent by the dispatching center node according to the pull stream request is received, sending a request message aiming at the target live broadcast video to the edge node indicated by the second reminding message.
In this embodiment of the application, if other edge nodes except the target edge node cache the target video data, that is, before receiving the pull stream request sent by the target edge node, the scheduling center node has received the pull stream request for the target live video sent by the other edge nodes.
Correspondingly, after receiving the pull flow request sent by the target edge node, the scheduling center node may send a second reminding message to the target edge node, where the second reminding message may carry address information of the other edge nodes.
Further, after receiving the second reminding message, the target edge node may send a request message for the target live video to the other edge nodes to obtain the target video data.
Based on the processing, the target edge node does not need to request the upper-layer node, and can directly acquire the target video data from other edge nodes, so that the time delay of the client for acquiring the video data can be further reduced, and the watching experience of the user is improved.
