Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
At present, a multi-line central server needs to load all mixed screen tasks, the pressure is high, and the business risk is high. Based on this, the load balancing method and apparatus, the distributed mixed screen server and the electronic device provided by the embodiments of the present invention can alleviate the mixed screen service pressure of the multi-line central server, and reduce the service risk.
To facilitate understanding of the present embodiment, first, a method for load balancing based on an edge device disclosed in the embodiment of the present invention is described in detail, referring to a schematic flow chart of the method for load balancing based on an edge device shown in fig. 1, where a distributed mixed-screen server includes a multi-line center server, a single-line edge server, and a service server, the method may be applied to the service server, and mainly includes the following steps S101 to S103:
step S101: the service server determines a service to be mixed with the screen, and the service to be mixed with the screen corresponds to a plurality of target single-line edge servers and a target multi-line center server.
Specifically, for a scene that a plurality of anchor broadcasters in a live video broadcast are connected with the wheat, when the anchor broadcasters are connected with the wheat, a plurality of paths of audio and/or video signals need to be mixed and then broadcast, so that a service server can receive a service to be mixed with a screen, the service to be mixed with the screen is a live broadcast room, and the live broadcast room corresponds to a plurality of target single-line edge servers and a target multi-line center server.
Step S102: the service server determines the load states of a plurality of target single-line edge servers and a target multi-line center server.
Considering that the target single-line edge server and the target multi-line center server have limited service load capacity, when the target single-line edge server and the target multi-line center server are in a saturated state, new mixed screen services cannot be received, and when the same server simultaneously loads excessive mixed screen services, the efficiency and the stability of the server are also influenced. Therefore, the service server can collect the load states of the servers with the screen mixing function (namely the single-line edge server and the multi-line center server) in real time, and select the optimal server to distribute the service according to the load states of the plurality of single-line edge servers. For example, each single-line edge server may send its load capacity and occupancy status to the traffic server, such as: the load capacity of a single-line edge server is 5, and the occupied condition is 2; the load capacity of one multi-line central server is 15 and the occupied case is 5.
Step S103: and the service server sends a screen mixing request to the idle server target single-line edge server or the target multi-line central server according to the load states of the target single-line edge servers and the target multi-line central server, and the screen mixing request indicates the idle server to mix the screen to be mixed with the screen service.
Specifically, the service server may select a server that is idle (i.e., the server with the best screen mixing effect) from the target single-line edge servers according to the load states of the target single-line edge servers and the target multi-line center server determined in step S102, such as: the load capacity of the target multi-line server is 10 and the target multi-line server is occupied 2; the load capacity of the first target single-line edge server is 5, and the first target single-line edge server is occupied by 0; the load capacity of the second target single-line edge server is 5, and the second target single-line edge server is occupied by 4, so that the first target single-line edge servers are all idle, and the service server can select to send a mixed screen request to the first target single-line edge server. And when the loads of all target single-line edge servers are saturated or the corresponding single-line edge server is not found by the screen mixing service, the service server can send a screen mixing request to the target central server. The target multi-line center server or the target single-line edge server can mix the received audio and/or video signals after receiving the screen mixing request, and send the audio and/or video signals after screen mixing to the client for playing.
Furthermore, because the processing resources needed by the video are more than the audio, and the single-line edge server is generally a slicing virtual machine and has weaker processing capacity, the audio mixing request can be sent to the first target single-line edge server, and the video mixing request can be sent to the target multi-line center server, so that the mixing capacity of the multi-line center server and the single-line edge server is reasonably utilized, and the mixing pressure of the multi-line center server is reduced. The first target single-line edge server can send the audio signal after screen mixing to the client, and the audio signal is combined with the video signal of the screen mixing of the target multi-line center server and then played.
In the method for load balancing based on the edge device provided by the embodiment of the present invention, after receiving a service to be mixed with a screen (the service to be mixed with a plurality of target single-line edge servers and a target multi-line center server), a service server may send a screen mixing request to a target single-line edge server that is relatively idle according to a load state of the plurality of target single-line edge servers (the screen mixing request may indicate the target single-line edge server that is relatively idle to perform screen mixing on the service to be mixed with a screen), or send the screen mixing request to the target multi-line center server when the load state of the target single-line edge server is saturated. According to the method, the business server can be used for distributing the business to be mixed with the screen to the idle single-line edge server or the multi-line center server, so that the screen mixing capability of the single-line edge server is fully utilized, the screen mixing business pressure of the multi-line center server is relieved, and the business risk is reduced.
Further, another load balancing method based on edge devices is provided in an embodiment of the present invention, see a flow diagram of another load balancing method based on edge devices shown in fig. 2, where the method may be applied to a multi-line central server, where the multi-line central server has 3 network cards respectively accessing 3 operators, so that there are 3 different IP addresses (telecom, connected, mobile), and then users of each line access sites of the same line through intelligent DNS domain name resolution, thereby improving access speed. The method mainly comprises the following steps S201 to S203:
step S201: the multi-line central server periodically sends the current load state to the service server.
Considering that the service server performs service distribution according to the load status of the multi-line center server and needs to acquire the load status information thereof, the multi-line center server may periodically send the current load status to the service server, such as: sending the current load status to the service server every 10 seconds, where the load status may include the load capacity and occupancy of the multiline center server, for example: load capacity 15 and occupied case 5.
Step S202: the multi-line center server receives a screen mixing request sent by the service server based on the current load state, the screen mixing request is used for indicating that the data of the service to be mixed is subjected to screen mixing, and the service to be mixed is provided with a plurality of clients correspondingly.
In a specific application, when the service server judges that the multi-line central server is idle based on the current load state, the service server can send the mixed screen request to the multi-line central server; the screen mixing request received by the multi-line center server can be an audio screen mixing request or a video screen mixing request, and can also be an audio video screen mixing request.
Step S203: and the multi-line central server performs screen mixing on the received data of the service to be subjected to screen mixing to obtain a screen mixing signal, and sends the screen mixing signal to the plurality of clients so that the clients can play the screen mixing signal conveniently.
For a better understanding of the above method, the following is exemplified: supposing that a first client user and a second client user carry out microphone connection in a live broadcast room, wherein the first client corresponds to a plurality of single-line edge servers and a multi-line center server, and the single-line edge servers and the multi-line center server send the current load state to a service server; the first client and the second client respectively send the data of the service to be mixed to the service server; after receiving the mixed screen service, the service server judges that no single-line edge server meeting the mixed screen requirement exists according to the load states of the single-line edge servers (namely the single-line edge server is saturated in load state or low in mixed screen speed, low in efficiency and the like), and then sends a mixed screen request to the multi-line center server; the first client and the second client respectively send the data of the screen mixing service to the multi-line central server; the multi-line center server receives the data of the service to be mixed and then performs screen mixing on the data to obtain a screen mixing signal, and sends the screen mixing signal to the first client and the second client for playing, so that the microphone connecting operation of the first client user and the second client user is realized.
Further, another load balancing method based on an edge device is provided in an embodiment of the present invention, referring to a flow diagram of another load balancing method based on an edge device shown in fig. 3, where the method is applied to a single-line edge server, the single-line edge server may be disposed on the same physical machine as an original single-line access server, and the single-line edge server has forwarding and screen mixing capabilities at the same time, and the method mainly includes the following steps S301 to S303:
step S301: the single-line edge server periodically sends the current load status to the traffic server.
Considering that the service server performs service distribution according to the load status of the single-line edge server, it needs to acquire its load status information in real time, so the single-line edge server may periodically send the current load status to the service server, such as: the current load status is sent to the traffic server every 10 seconds, and may include the load capacity and occupancy of a single-line edge server, such as: load capacity is 5 and occupied case is 3.
Step S302: the single-line edge server receives a screen mixing request sent by the service server based on the current load state, wherein the screen mixing request is used for indicating that screen mixing is carried out on data of a service to be mixed, and the service to be mixed corresponds to a plurality of clients.
In a specific application, when the service server judges that the single-line edge server is idle based on the current load state, the mixed screen request can be sent to the single-line edge server; the screen mixing request received by the single-line edge server can be an audio screen mixing request or a video screen mixing request, and can also be an audio video screen mixing request. When the single-line edge server and the multi-line center server are idle, the service server can preferentially send the video mixed screen request to the multi-line center server and send the audio mixed screen signal to the single-line edge server, so that the mixed screen server is used more evenly, and the service pressure of the center server is reduced.
Step S303: and the single-line edge server performs screen mixing on the received data of the service to be subjected to screen mixing to obtain a screen mixing signal, and transmits the screen mixing signal to a plurality of clients so that the clients can play the screen mixing signal conveniently.
For a better understanding of the above method, the following is exemplified: supposing that a first client user and a second client user are connected in a live broadcast room, wherein the first client corresponds to a plurality of single-line edge servers and a multi-line center server, and the single-line edge servers and the multi-line center server send the current load state of the single-line edge servers and the multi-line center server to a service server; the first client and the second client respectively send the data of the service to be mixed to the service server; after receiving the mixed screen service, the service server judges to obtain an optimal single-line edge server according to the load states of the plurality of single-line edge servers (namely, the load is small, the mixed screen efficiency is high, the speed is high and the like), and sends a mixed screen request to the optimal single-line edge server; the first client and the second client respectively send the data of the service to be mixed to the single-line edge server; and the optimal single-line edge server receives the data of the service to be mixed with the screen, then mixes the screen to obtain a mixed screen signal, and sends the mixed screen signal to the first client and the second client for playing, so that the microphone connecting operation of the first client user and the second client user is realized.
Further, an embodiment of the present invention further provides a distributed mixed-screen server, referring to a schematic structural diagram of the distributed mixed-screen server shown in fig. 4, which illustrates that the distributed mixed-screen server includes a multi-line center server 10, a single-line edge server 20, and a service server 30.
The service server 30 is configured to determine a service to be mixed, where the service to be mixed corresponds to a plurality of target single-line edge servers and a target multi-line center server; and the system is also used for sending a screen mixing request to the idle target single-line edge server and/or the target multi-line central server according to the load states of the target single-line edge servers and the target multi-line central server.
The multi-line center server 10 and the single-line edge server 20 are used for receiving and executing the screen mixing request and forwarding data of the service to be screen mixed.
The distributed mixed screen server provided by the embodiment of the invention comprises a multi-line center server, a single-line edge server and a service server, wherein the service server can send a mixed screen request to a relatively idle server (the mixed screen request indicates that the relatively idle server mixes the screen to the mixed screen service) according to the load states of a plurality of target single-line edge servers and a target multi-line center server after receiving the to-be-mixed screen service (the to-be-mixed screen service corresponds to a plurality of target single-line edge servers and one target multi-line center server). According to the method, the business server can be used for distributing the business to be mixed to the idle single-line edge mixed screen server or the multi-line central server, so that the screen mixing capability of the single-line edge server is fully utilized, the screen mixing business pressure of the multi-line central server is relieved, and the business risk is reduced.
Further, the distributed mixed-screen server further includes: and the single-wire access server is used for forwarding the data of the service to be mixed. The single-wire access server and the single-wire edge server can be arranged on the same physical machine, and the mixed screen service function is added to the node which is responsible for forwarding at the original value.
In order to better understand the functions of the distributed screen mixing server, an embodiment of the present invention further provides another structural schematic diagram of the distributed screen mixing server, and reference is made to fig. 5, where two clients, a client C1, correspond to a single-line edge server as an example, and the distributed screen mixing server is illustrated to include: the system comprises a client C1, a client C2, a first single-line access server, a single-line edge server, a multi-line center server, a service server and a second single-line access server.
When the client C1 and the client C2 are connected in a live broadcast room, the service client receives the mixed screen service sent by the client C1 and the client C2, and the client C1 sends first data of the mixed screen service to the single-line edge server through the first single-line access server; the client C2 sends the second data of the mixed screen service to the multi-line center server through the second single-line access server, and the multi-line center server forwards the second data to the single-line edge server; the single-wire edge server performs screen mixing on the received first data and the received second data to obtain a screen mixing signal; the single-wire edge server sends the mixed screen signal to the client C1 through the first single-wire access server for playing, meanwhile, the single-wire edge server forwards the mixed screen signal to the second single-wire access server through the multi-wire center server, and the second single-wire access server sends the mixed screen signal to the client C2 for playing, so that the wheat connecting operation of the client C1 and the client C2 is achieved.
When the single-line edge server is saturated or the mixed screen effect is poor, a mixed screen request can be sent to the multi-line center server, namely the client C1 sends first data of the mixed screen service to the single-line edge server through the first single-line access server, and the single-line edge server forwards the first data to the multi-line center server; the client C2 sends the second data of the mixed screen service to the multi-line central server through a second single-line access server; the multiline central server performs screen mixing on the received first data and the received second data to obtain a screen mixing signal; the multi-line center server forwards the mixed screen signal to the first single-line access server through the single-line edge server, the first single-line access server sends the mixed screen signal to the client C1 to be played, and meanwhile, the multi-line center server sends the mixed screen signal to the client C2 to be played through the second single-line access server, so that the wheat connecting operation of the client C1 and the client C2 is achieved.
The distributed mixed screen server distributes the mixed screen service to the idle servers through the service server, so that the mixed screen pressure of the multi-line central server is relieved, and the stability of a system and data transmission in the live broadcast process is effectively improved.
