Description

Technical Field

[0001] The present application relates to the field of network service technology, and in particular to a live streaming load method and device, an electronic device, and a storage medium. Background Art

[0002] At present, in the live broadcast scenario, the finest granularity of the actual content distribution network (CDN) to distribute content is the flow dimension. The content distribution network is a distributed network composed of edge node server clusters distributed in different regions. It distributes user content to edge nodes, effectively solving the Internet network congestion and improving the response speed of users accessing websites. In the scheduling scenario, scheduling is mostly performed according to the domain name dimension, which will cause a decrease in the hit rate (for example, the user requests the corresponding node according to the domain name, but there is no such flow on the node). In order to improve the hit rate, the same flow can be directed to the same node for service through means such as 302. However, this will also cause the water level of the node that undertakes this flow to be too high, resulting in problems with the node service quality, and scheduling is required for relevant control.

[0003] In related technologies, when the node water level (the ratio of the node load to the node threshold, reflecting the node load level) is too high, the node will be prohibited from providing services, and another node will be used to replace the node with excessive load. After directly replacing the node, the new node will take over all the traffic from the previous node, causing the new node to quickly increase in capacity and run full, resulting in an avalanche due to the high water level. At the same time, the original node will quickly decrease in capacity, resulting in a waste of resources.

[0004] Therefore, there are technical problems in the related art such as waste of original node resources and too high water level of new node during node replacement. Summary of the invention

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] According to one aspect of an embodiment of the present application, a method for controlling a load of a live stream is provided. Optionally, in this embodiment, the method for controlling a load of a live stream can be applied to Figure 1 In the hardware environment composed of terminal 1402 and server 1404 shown in FIG. Figure 1 As shown, server 1404 is connected to terminal 1402 via a network, and can be used to provide services (such as game services, application services, etc.) for the terminal or a client installed on the terminal. A database can be set up on the server or independently of the server to provide data storage services for server 1404.

[0046] The above network may include but is not limited to at least one of the following: wired network, wireless network. The above wired network may include but is not limited to at least one of the following: wide area network, metropolitan area network, local area network, and the above wireless network may include but is not limited to at least one of the following: WIFI (Wireless Fidelity), Bluetooth. The terminal may not be limited to a PC, a mobile phone, a tablet computer, etc.

[0047] The load control method of the live streaming of the embodiment of the present application can be executed by a server, or by a terminal, or by both a server and a terminal. The terminal can also execute the load control method of the live streaming of the embodiment of the present application by a client installed thereon.

[0048] Taking the live streaming load control method in this embodiment executed by the server as an example, Figure 2 A method for controlling a live stream load provided in an embodiment of the present application includes the following steps:

[0049] Step S202, obtaining the current load of the target node.

[0050] The live streaming load control method in this embodiment can be applied to scenarios where it is necessary to control the resources of a node used to serve the live streaming.

[0051] In this embodiment, the target node can be any edge node in any content distribution network. The edge node is also called CDN node, Cache node, etc., which refers to a network node with fewer intermediate links from the end user access and has better response capability and connection speed for the end access user. The content distribution network effectively solves the Internet network congestion by distributing user content to edge nodes and improves the response speed of users accessing websites.

[0052] In the live broadcast scenario, it is necessary to ensure that the content can be transmitted to users quickly and stably. Therefore, it is necessary to ensure the stability of the target node to avoid overload. In addition, the node load can be obtained as follows:

[0053] Monitoring tools can help monitor the load of nodes in real time by monitoring tool sets and analyzing the performance data of target nodes. Optional monitoring tools and technologies may include: Prometheus: an open source monitoring and alarm system that can be used to collect and store node monitoring data; Grafana: used to visualize monitoring data and can display the load of nodes; Zabbix: an enterprise-level monitoring tool that supports monitoring network devices, servers, applications, etc.

[0054] In addition, the target node itself can also regularly report its status information, including CPU usage, memory usage, network bandwidth usage, etc. It can report its current status by sending heartbeat packets to the central management system at regular intervals; in addition, it can also actively report the status when the target node status changes significantly (such as CPU usage reaches a threshold), etc.

[0055] Step S204, when it is determined that the current load exceeds the preset upper limit, all current live streams in the target node are determined.

[0056] Specifically, a preset upper limit of the target node may be preset, and the preset upper limit may be a preset value used to characterize that the node water level (the ratio of the node load to the node threshold, reflecting the node load level) of the target node is too high, for example, 0.9, 0.8, etc.

[0057] When it is determined that the current load exceeds the preset upper limit, it means that there are too many users watching the live broadcast through the target node, that is, the current live stream served by the target node has a high viewing volume, which has caused a large load on the target node. Therefore, the target node needs to stop serving some of the current live streams. Based on this, it is necessary to determine all the current live streams currently served by the target node.

[0058] Step S206, determining a preset number ratio of target live streams from all current live streams, wherein the preset number ratio is a ratio of the target load to the current load.

[0059] In this embodiment, the target live stream that needs to be continued to be served is determined according to the ratio of the target load to the current load. The target load is the load required to control the target node. Therefore, the preset quantity ratio can be obtained by dividing the target load by the current load. The target live stream is the live stream that needs to be continued to be served by the target node.

[0060] In general, a node will be used to serve multiple live streams. When there are a large number of live streams, a preset number of target live streams can be selected by randomly selecting all current live streams. Since the target node serves a large number of current live streams, even if the loads corresponding to different live streams are different, the ratio between the target load corresponding to the target live stream selected in this way and the current load will also be close to the preset number ratio.

[0061] like Figure 3 As shown, as an optional implementation, the step S206 of determining a preset number of target live streams in all current live streams can be implemented by the following steps S302 and S304:

[0062] Step S302, determining a hash value corresponding to each current live stream.

[0063] That is to say, a hash value calculation may be performed on each current live stream, thereby obtaining a hash value corresponding to each current live stream. Generally, the hash values ​​corresponding to different live streams are different.

[0064] like Figure 4As shown, as an optional implementation, the step 302 of determining the hash value corresponding to each current live stream can be implemented by the following steps:

[0065] Step S402: Determine a live stream identifier corresponding to each current live stream.

[0066] Generally, in order to distinguish different live streams, a live stream identifier uniquely corresponding to each live stream is generated in advance, and then the live stream identifier corresponding to each current live stream can be directly determined.

[0067] Step S404, performing hash value calculation on all live stream identifiers to obtain a hash value corresponding to each current live stream.

[0068] That is to say, in this embodiment, the hash value corresponding to each current live stream is obtained by calculating the hash value of the live stream identifier. Furthermore, in this embodiment, the hash value corresponding to each current live stream is obtained by inputting the live stream identifier into a preset hash algorithm. Optionally, the hash algorithm can be MD5, SHA-1, SHA-256, FNV-1a, etc. Preferably, the hash algorithm is the FNV-1a hash algorithm. By adopting the FNV-1a hash algorithm, the characteristics of fast calculation speed and uniform distribution of hash value calculation can be achieved, so that the load corresponding to all target live streams can be closer to the target load, thereby achieving a better load control effect.

[0069] Step S304: determine the target live stream from all current live streams according to a preset quantity ratio and based on the hash value.

[0070] After determining the preset quantity ratio, since the hash value generally satisfies the characteristic of uniform distribution within the value range (for example, between 0-1), the target live stream can be determined by interval selection in the hash value. For example, within the hash value interval, the current live stream in the sub-interval of the preset quantity ratio is randomly selected as the target live stream.

[0071] For example, when the preset quantity ratio is 0.3 and the hash value range is [0,1], the current live stream with a hash value in the interval [0,0.3] can be determined as the target live stream, the current live stream with a hash value in the interval [0.1,0.4] can be determined as the target live stream, the current live stream with a hash value in the interval [0.7,1] can be determined as the target live stream, and so on. They are not listed one by one here.

[0072] As an optional implementation, the aforementioned step S304 can be implemented by the following steps to determine the target live stream among all current live streams according to the preset quantity ratio and based on the hash value: among all current live streams, determine the designated live stream whose hash value is less than the preset quantity ratio, wherein the value range of the hash value is consistent with the value range of the preset quantity ratio; determine the designated live stream as the target live stream. That is, in this embodiment, the value range of the hash value is consistent with the value range of the preset quantity ratio, that is, when the value range of the preset quantity ratio is [0,1], the value range of the hash value is also [0,1]; when the value range of the preset quantity ratio is [0,100], the value range of the hash value is also [0,100]. Furthermore, after determining the hash value of the current live stream, directly use the designated live stream whose hash value is less than the preset quantity ratio as the target live stream. For example, when the preset number ratio is 0.3 and the hash value range is [0,1], the current live stream with a hash value less than 0.3 can be determined as the target live stream; when the preset number ratio is 0.4 and the hash value range is [0,1], the current live stream with a hash value less than 0.4 can be determined as the target live stream.

[0073] Step S208, stopping the services of all live streams to be transferred in the target node, and maintaining the services of all target live streams, wherein the live streams to be transferred are other current live streams in the current live stream except all target live streams.

[0074] After determining the target live stream, other current live streams except all target live streams can be determined as live streams to be transferred that need to be served by other nodes. Therefore, the service of all live streams to be transferred can be stopped in the target node and the service of all target live streams can be maintained.

[0075] Through the method of this embodiment, by continuing to serve a preset proportion of target live streams in the target node and stopping the service for other live streams to be transferred, the resources in the target node will not be idle, and even if the live streams to be transferred are transferred to the same new node, the water level of the new node will not be too high, thereby avoiding problems with the service quality of the new node; thereby achieving the technical effect of effectively utilizing the resources of the target node and avoiding the water level of the new node being too high, thereby solving the technical problems of waste of original node resources and too high water level of the new node during node replacement in the related technology.

[0076] like Figure 5 As shown, as an optional implementation, as in the above method, after stopping the services of all live streams to be transferred in the target node in step S208, the method further includes the following steps:

[0077] Step S502: Determine a designated node to undertake the transfer of the live stream from among all candidate nodes.

[0078] Specifically, the relevant implementation methods of the aforementioned embodiments can be executed by the central SDC (Service Discovery and Control Center), and after determining the live stream to be transferred, the central SDC can determine an idle designated node among all candidate nodes under its control that can be used to take over the above-mentioned transferred live stream.

[0079] Step S504, controlling the designated node to pull the live stream to be transferred, so as to provide services for the live stream to be transferred through the designated node.

[0080] After determining the designated node, the central SDC can instruct the designated node to pull the live stream to be transferred, so that the designated node can provide services for the live stream to be transferred; further, the designated node can include one or more, and then all the live streams to be transferred can be transferred to the same designated node or to different nodes.

[0081] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0082] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM (Read-Only Memory) / RAM (Random Access Memory), a magnetic disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods of each embodiment of the present application.

[0083] According to another aspect of an embodiment of the present application, a live stream load control device for implementing the above-mentioned live stream load control method is also provided.

[0085] A determination module 62, configured to determine all current live streams in the target node when it is determined that the current load exceeds a preset upper limit;

[0086] The target live stream determination module 63 is used to determine a preset number of target live streams in all current live streams, wherein the preset number ratio is a ratio of the target load to the current load;

[0087] The processing module 64 is used to stop the services of all live streams to be transferred in the target node and maintain the services for all target live streams, wherein the live streams to be transferred are other current live streams in the current live stream except all target live streams.

[0089] Through the above module, by continuing to serve a preset proportion of target live streams in the target node and stopping the service for other live streams to be transferred, the resources in the target node will not be idle. Even if the live streams to be transferred are transferred to the same new node, the water level of the new node will not be too high, thus avoiding problems with the service quality of the new node. The technical effect of effectively utilizing the resources of the target node and avoiding the water level of the new node being too high is achieved, thereby solving the technical problems of waste of original node resources and too high water level of the new node during node replacement in related technologies.
