Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
The embodiment of the application can be applied to a live scene, and a distributed system is adopted to provide live service. In order to provide live broadcast service more conveniently, the problems that a next layer node in a system requests video data to an upper layer node, the bandwidth is occupied and the like are solved. The embodiment of the application can realize scheduling among the edge nodes in the same layer.
In a live broadcast system shown in fig. 1, a live broadcast data service is provided for a user equipment through an edge node, where the live broadcast data service includes an edge node 1, an edge node 2 … …, and the user equipment includes a user equipment 1 and a user equipment 2. The live broadcast system also comprises a management server, and the management server at least comprises the following functions: the control function, the log function, and the scheduling function may further include other management functions such as stream pushing, which is not limited in this embodiment of the present application. The above-described management functions may be provided in one server, or may be provided in different servers or server clusters. As an example, the different servers in fig. 1 include a control server, a log server and a scheduling server.
The control server can manage and control the playing of the live video in the live system, including determining the number of people watching the live video, the popularity of the live video and the like. The log server is used for recording logs of the live broadcast system, including related logs of live broadcast video playing, logs of live broadcast watched by users and the like. The respective control server may determine relevant information of the live video based on the log. The scheduling server is used for scheduling the live video, for example, scheduling a user request among different edge nodes, and the like, and can also obtain a log from the log server to determine the playing condition of the video.
The method comprises the steps that a user can use user equipment to access a live broadcast system to watch live broadcast video data, a live broadcast client is started on the user equipment, the client can display a live broadcast page, the user can select a live broadcast video to be watched from the live broadcast page and generate a corresponding playing request to a server, and an edge node of the live broadcast server processes the request of the user.
Referring to fig. 2, a flowchart illustrating steps of an embodiment of a live scheduling method of the present application is shown.
In a live broadcast system, an edge node closest to a user provides a service for the user, and a corresponding edge node receives a play request of a client, and can acquire a target live broadcast video to be requested from the play request, for example, the target live broadcast video can be determined based on a video identifier, a play address, and the like.
The edge node analyzes the target live video to determine whether scheduling needs to be executed, and determines a destination address of scheduling corresponding to the target live video when the target live video meets scheduling conditions. The scheduling condition is a condition for scheduling the live video, and can be determined according to the playing condition of the live video, and the live video meeting the scheduling condition is scheduled to other edge nodes to provide services.
In an alternative embodiment, log data is obtained; and judging whether the target live video meets scheduling conditions or not according to the log data. The log data may be obtained from a log server and then analyzed to determine whether the target live video meets scheduling conditions. The log can determine the watching amount (or playing amount) of the live video data, and the like, and in a live scene, the watching amount (or playing amount) of the live video refers to the number of clients watching the live video. The playing condition of the live video can be determined according to the number of users watching the live video (the number of online users) or the playing amount of the live video, and whether the target live video meets the scheduling condition can be judged according to the playing condition of the live video.
Wherein, the judging whether the target live video meets the scheduling condition according to the log data comprises: determining the playing quantity corresponding to the target live video according to the log data; comparing the playing number with a playing threshold value; when the playing quantity is larger than the playing threshold value, judging that the target live video does not meet the scheduling condition; and when the playing quantity is less than or equal to the playing threshold value, judging that the target live video meets the scheduling condition. The playing quantity corresponding to the target live video can be determined through the live data, the playing quantity can be the current online user quantity of the live video, a playing threshold value can be set, the playing threshold value is a threshold value for measuring the playing condition of the live video, therefore, the playing quantity can be compared with the playing threshold value, when the playing quantity is larger than the playing threshold value, the heat degree of the target video data is considered to be higher, namely more users watch, the corresponding live streaming of the target video data can be called as heat flow, and therefore the target live video does not meet the scheduling condition. In contrast, when the playing number is less than or equal to the playing threshold, the target video data is considered to be less hot, that is, less users are watching, and the corresponding live stream of the target video data may be called a cold stream, so that the target live video satisfies the scheduling condition.
In other scenes, the control server can acquire log data from the log server, so that the cold and hot conditions of the live stream can be counted in real time, and certainly, the cold and hot conditions of the live stream can also be counted in real time by the log system, and then the cold and hot conditions of the live stream are fed back to the control server. The control server can then determine live video data belonging to the hot stream based on the cold and hot conditions of the live stream, and generate a live video list based on the live video data. The judgment of the cold and hot conditions of the live streaming can adopt a mode of comparing the playing quantity with a playing threshold value, correspondingly belongs to live video data of heat flow, and the playing quantity is greater than the playing threshold value, namely, the live video in the live video list is the live video of which the playing quantity is greater than the playing threshold value. The control server may send a list of live videos to each edge node. Therefore, in an optional embodiment, a live video list is received, and live videos in the live video list are live videos of which the playing quantity is greater than a playing threshold value; the edge node can also directly judge whether the target live video meets the scheduling condition based on the live video list. If the target live video is in the live video list, judging that the target live video does not meet a scheduling condition; and if the target live video is not in the live video list, judging that the target live video meets the scheduling condition.
For example, the client of the user equipment 2 sends a play request to the edge node 2, and the edge node 2 determines that the target live video requested by the edge node 2 meets the scheduling condition, and may request a scheduling destination address from the scheduling server.
And 204, determining a destination address of the corresponding scheduling of the target live video under the condition that the target live video meets the scheduling condition.
The target live video satisfying the scheduling condition is live video with a small number of watched by the user, and therefore, video data of the target live video is not available on all edge nodes. In order to avoid that the edge node does not have the video data of the target live video, the data needs to be requested to the upper-layer node, and the internal bandwidth of the system is occupied. Therefore, the cold-flow target live video can be uniformly dispatched to the designated edge node, so that the address of the target video data on the designated edge node can be determined as the destination address, and the target live video can be dispatched to the destination address.
In an optional embodiment, in a case that the target live video meets a scheduling condition, determining a destination address of a schedule corresponding to the target live video includes: sending a scheduling request under the condition that the target live video meets the scheduling condition; and receiving a destination address of the corresponding scheduling of the target live video. The scheduling of the live video can be executed by the scheduling server, so that the edge node can send a scheduling request to the scheduling server, the scheduling server determines the destination address of the target live video scheduling, and then the destination address of the target live video scheduling is sent to the edge node, and the destination address of the target live video corresponding to the scheduling can be received.
In the embodiment of the application, in order to ensure the quality of the live video, a scheduling time period can be set, wherein the scheduling time period is a time period allowing video scheduling, and the scheduling time period can be set by the management server and then issued to the edge node, so that the edge node can detect whether the video is in the scheduling execution time period, and if the video is in the scheduling execution time period, the edge node triggers the sending of the scheduling request. The edge node can detect whether the current time is in the time period for executing the scheduling, and if so, the edge node triggers the sending of the scheduling request so as to schedule the video data. If not within the time period for performing scheduling, the video data of the target video may be requested to the upper node.
And step 206, feeding the destination address back to the client, so that the client can request the target live video again according to the destination address.
The edge node can feed the destination address back to the client, so that the client can resend the playing request based on the destination address and send the request to the specified edge node where the destination address is located, and the video data of the target live video is obtained. As described above, the scheduling service analyzes and then determines that the edge node 1 provides the service, and determines the corresponding destination address. The edge node 2 receives the destination address sent by the scheduling server, and can send the destination address to the user equipment 2, so that the client of the user equipment 2 receives the destination address and then requests the edge node 1 for live video.
On the basis of the foregoing embodiment, the scheduling server may perform scheduling of live video data for cold streams, which may specifically be implemented by the following steps:
referring to fig. 3, a flow chart of steps of another embodiment of a live scheduling method of the present application is shown.
The scheduling server may receive a scheduling request of the edge node, determine a target live video from the scheduling request, and determine the target live video based on a video identifier, a source play address of the target live video, and the like.
And 304, analyzing the playing address of the target live broadcast video, and determining a scheduled target address.
The scheduling server can analyze the playing address of the target live broadcast video, and the playing address can be a source playing address of the target live broadcast video, namely an address for uploading the target live broadcast video to a source station. The designated edge node to be scheduled for the target live video can be analyzed based on the play address, and a corresponding scheduled target address is determined.
In an optional embodiment, the analyzing the playing address of the target live video and determining the scheduled target address includes: calculating a hash value of a playing address of the target live video; determining an edge node corresponding to the target live video according to the hash value; and determining the playing address of the target live broadcast video in the edge node as a scheduled target address. A hash algorithm may be used, a hash value may be calculated by using a play address of a target live video, an edge node corresponding to and designated by the target live video may be determined based on the hash value, and then the play address of the target live video in the edge node is determined as a scheduled target address. Determining an edge node corresponding to the target live video according to the hash value includes: determining the number of edge nodes of the designated area; and determining edge nodes corresponding to the target live video in the edge nodes of the designated area according to the number of the edge nodes and the hash value. The edge nodes generally have regional characteristics, for example, a plurality of edge nodes are arranged in a region such as province and city to provide services, so that scheduling can be performed in the region, the number of the edge nodes in the designated region can be determined, the hash value of the target live video is left according to the number of the edge nodes to obtain a corresponding calculation result, and the edge node corresponding to the target live video is determined in the edge nodes in the designated region according to the numerical value of the calculation result. If the edge nodes in the designated area can be numbered, the numerical value of the residue result determines that the corresponding number is the edge node designated by the dispatching, and the destination address of the target video data at the edge node is determined.
In the embodiment of the application, sometimes, the edge nodes may have a fault and other reasons, which may result in that services cannot be provided, in this case, the number of the edge nodes may change, and in order to ensure the stability of scheduling, the virtual nodes may be determined based on a hash ring and other manners, and the calculation may be performed based on the virtual nodes, so as to ensure the stability of the calculation result.
In other scenarios, after the destination address of the schedule is determined, the playing address of the target video and the destination address of the schedule can be put into a schedule list, so that the schedule list can be directly queried for the target live video with the destination address determined. Therefore, analyzing the playing address of the target live broadcast video to determine the scheduled target address further includes: inquiring a scheduling list by using the playing address of the target live video; if the playing address is inquired in the inquiry scheduling list, acquiring a destination address of scheduling corresponding to the playing address; and if the playing address is not inquired in the inquiry scheduling list, executing the step of calculating the hash value of the playing address of the target live video.
After the scheduled destination address is determined, the destination address can be sent to the requested edge node, so that the target live broadcast video is scheduled to be played. The method and the system have the advantages that the scheduled target address is returned to the client side so as to be scheduled, the method and the system can be realized based on corresponding protocols, various protocol scenes can be supported, and the protocols can be expanded so as to realize the method. The method can be applied to playing of protocols such as hypertext Transfer Protocol (HTTP) and the like, and can also be applied to scenes such as short-delay live broadcast and the like, such as Real-Time Communications (RTC) playing and the like.
In summary, when a client requests a target live video, if the target live video meets a scheduling condition, the target live video can be scheduled, so that a destination address of the target live video corresponding to scheduling can be determined, and the destination address is fed back to the client, so that the client re-requests the target live video according to the destination address, thereby reducing a situation that an edge node requests a video from an upper node and reducing waste of bandwidth in a system.
On the basis of the embodiment, the hit rate of live broadcast can be improved through scheduling. The hit rate of live broadcast refers to the probability of hitting live broadcast video by an edge node of live broadcast service. Wherein, the hit rate of live broadcast is (play bandwidth-back source bandwidth)/play bandwidth. The play bandwidth refers to the bandwidth of the current external service of the node. Back source bandwidth refers to the bandwidth that the node pulls the real-time media stream towards an upstream node or source station. If the node does not carry out scheduling, when the node does not have the video stream of the target live video, the video stream needs to be pulled to the upper side, and if the node on the upper layer does not have the video stream, the node needs to continue to return to the source station of the target live video, so that the video stream is obtained. The bandwidth in the system is occupied in the process of pulling up the video stream, and the system corresponds to other live broadcasts. By the mode, the video stream is not pulled back to the source upwards, but is directly scheduled to other nodes, so that the bandwidth in the system is not occupied.
On the basis of the above embodiment, the embodiment of the present application further provides a live broadcast scheduling method, which implements scheduling of cold-streaming live broadcast video in a live broadcast system.

Calculating a hash value of a playing address of the target live broadcast video; determining an edge node corresponding to the target live video according to the hash value; and determining the playing address of the target live broadcast video in the edge node as a scheduled target address.
The determining the edge node corresponding to the target live video according to the hash value includes: determining the number of edge nodes of the designated area; and determining edge nodes corresponding to the target live video in the edge nodes of the designated area according to the number of the edge nodes and the hash value.
Analyzing the playing address of the target live broadcast video to determine a scheduled target address, further comprising: inquiring a scheduling list by using the playing address of the target live video; if the playing address is inquired in the inquiry scheduling list, acquiring a destination address of scheduling corresponding to the playing address; and if the playing address is not inquired in the inquiry scheduling list, executing the step of calculating the hash value of the playing address of the target live video.
In step 418, the dispatch server sends the dispatched target address to the first edge node.
Step 420, the first edge node feeds back the destination address to the client.
In step 422, the client sends a play request to the second edge node according to the destination address.
Step 424, the second edge node sends the video stream of the target live video to the client.
And step 426, the client analyzes the video stream and plays the target live video.
Therefore, live video needing to be scheduled can be scheduled to other nearby edge nodes to provide services, and the occupation of the internal bandwidth of the system is reduced.
Referring to fig. 5, a flowchart illustrating steps of an alternative embodiment of a live scheduling method of the present application is shown.
And if the scheduling request is triggered to be sent in the scheduling execution time period, the scheduling request is sent.
If so, go to step 510, otherwise, go to step 512.
And step 510, judging that the target live video does not meet the scheduling condition.
And when the playing quantity is larger than the playing threshold value, judging that the target live video does not meet the scheduling condition. The process can be ended, and the video stream of the target live video can be directly sent to the client.
