Referring to fig. 2, a flowchart of a method for distributing a push task is provided in an embodiment of the present application. As shown in fig. 2, the method according to the embodiment of the present application may include the following steps:
s201, when the course starts, determining the room number of the virtual classroom associated with the course.
Before a student takes lessons, the students reserve the lessons on the service console through the terminal equipment, and information such as the lesson starting time, the lesson ending time and subject contents of the lessons is set. When the lesson time arrives, the service console allocates a virtual classroom and a room number of the virtual classroom to the lesson, wherein the room number is used for uniquely representing the identity of the virtual classroom. The task distribution server may determine the room number of the virtual classroom associated with the lesson in the service console.
The virtual classroom is a logic space distributed by the service console and used for students and teachers to give lessons, the virtual classroom comprises classroom lessons-giving terminal equipment and student lessons-giving terminal equipment, and the terminal equipment in the virtual classroom can perform voice intercom, text chat and video playing operations.
S202, inquiring in a local list according to the room number.
The local list is a storage space used for storing mapping relation information and arranged in the task distribution server, and the data structure of the local list comprises, but is not limited to, an array, a stack, a linked list, a hash table and the like. The task distribution server queries corresponding mapping relation information in the local list by taking the room number as an index, the mapping relation information represents the mapping relation between the room number and a server identifier, and the server identifier represents the unique identity of the pushing server for executing the pushing task. When the task distribution server queries in the local list according to the room number, the query result may be that no mapping relation information corresponding to the room number exists or mapping relation information corresponding to the room number exists.
S203, if the mapping relation information corresponding to the room number does not exist, the mapping relation information corresponding to the room number is inquired in the sharing server.
The shared server can be an independent server or a cluster formed by a plurality of servers, a database is deployed on the shared server, the type of the database can be a redis database, the shared server and the task distribution cluster are mutually communicated, and the mapping relation information stored by the shared server and the mapping relation stored on each task distribution server in the task distribution cluster are ensured to be kept synchronous. When the mapping relation information corresponding to the room number is not queried in the local list, the task distribution server queries in the sharing server, and the mapping relation information configured by each completed task distribution server is stored in the sharing server, so that the mapping relation information associated with the room number can be queried in the sharing server.
S204, determining the server identification associated with the room number according to the mapping relation information.
The server identification associated with the room number is determined by analyzing the mapping relation information, and the server identification can be an IP address, a MAC (media access control ) address or other identifications.
S205, determining a target pushing server in the pushing cluster according to the server identification, and indicating the target pushing server to push media streams to terminal equipment in the virtual classroom.
The task distribution server determines a corresponding target push server in the push cluster according to the server identification, and then instructs the target push server to push media streams to terminal equipment in the virtual teaching room. For example: the task distribution server sends a push task instruction to a target push server with a determined target, the push task instruction carries a material identifier, the target push server inquires a lesson material from a material library from the material identifier, and the lesson material is used for pushing a streaming media stream for a terminal device in a virtual classroom. If the scene is a live broadcast scene, pushing the teacher media stream uploaded by the terminal equipment of the teacher to the terminal equipment in the virtual classroom; if the recorded broadcast scene is the recorded broadcast scene, generating a teacher media stream from a pre-stored media file, and pushing the teacher media stream to terminal equipment of each student; if the lesson scene is AI (artificial intelligence ), lesson materials are selected from a material library according to lesson contents, media streams of AI teachers are generated according to the materials, and then terminal equipment of each student in the virtual classroom is pushed to the teacher media streams.
When the scheme of the embodiment of the application is executed, when a course starts, the task distribution server firstly queries mapping relation information in a local list according to the room number of the course, if the mapping relation information is not queried, the mapping relation information corresponding to the room number is queried in the sharing server, the mapping relation is analyzed to obtain a server identifier, then a target push server corresponding to the server identifier is determined in a push cluster, the target push server is instructed to push to a virtual classroom corresponding to the room number, and the mapping relation information is not required to be queried in the sharing server every time before the push, so that the query times of the sharing server are reduced, the push task distribution efficiency is improved, and the processing cost of the sharing server is reduced.
Referring to fig. 3, a flowchart of a method for distributing a push task is provided in this embodiment, where an execution body of this embodiment is a task distribution server. The distribution method of the push task can comprise the following steps:
s301, sending a subscription request message to the sharing server.
The task distribution server sends a subscription request message to the sharing server, wherein the task distribution server is any one server in the task partition cluster, the subscription request message is used for subscribing updated mapping relation information to the sharing server, the subscription request message carries a server identifier of the task distribution server, and the server identifier comprises one or more of an IP address, a port number and a MAC address.
S302, when the mapping relation information stored in the sharing server is updated, the updated mapping relation information sent by the sharing server is received.
The method comprises the steps that a shared server receives a subscription request message from a task distribution server, when mapping relations on the shared server are updated, updated mapping relation information is sent to all subscribed task distribution servers, and the condition for triggering the updating of the mapping relation information on the shared server can be: and the plug-flow server cluster expands or contracts capacity.
For example: the method comprises the following steps that in a plug-in cluster capacity expansion scene, a task distribution cluster comprises 2 task distribution servers, namely a task distribution server 1 and a task distribution server 2, and 4 plug-in servers are pre-included in the plug-in cluster, namely a plug-in server 1, a plug-in server 2, a plug-in server 3 and a plug-in server 4. The task distribution server 1 manages the push server 1 and the push server 2, and the task distribution server 2 manages the push server 3 and the push server 4, and the mapping relationship information stored in the local list of the task distribution server 1 is expressed as: (push server 1, virtual classroom 1), (push server 2, virtual classroom 1), the mapping relationship information stored in the local list of the task distribution server 22 is expressed as: (plug-flow server 3, virtual classroom 2), (plug-flow server 4, virtual classroom 3). The mapping relationship stored on the shared server is expressed as: (push server 1, virtual classroom 1), (push server 2, virtual classroom 1), (push server 3, virtual classroom 2), (push server 4, virtual classroom 3), i.e. the shared server stores complete mapping relation information. When the push cluster expands, a push server 5 is added in the push cluster, the shared server distributes the push server 5 to the task distribution server 2 for management, then the push server 5 is bound with the virtual classroom 2, and then the mapping relation information on the shared server is updated, and the mapping relation information is newly added: (push server 5, virtual classroom 2), the sharing server pushes the mapping relation information to the task distribution server for storage.
When the task distribution clusters are expanded or contracted, the sharing server can redistribute managed plug flow clusters for each task distribution server in the task distribution clusters, and then synchronize mapping relation information of the plug flow servers managed by each task distribution server and the virtual classrooms to the corresponding task distribution servers.
For example: the task distribution cluster includes: the task distribution server 1, the plug-flow cluster includes: the push server 1, the push server 2, the push server 3 and the push server 4, the task distribution server 1 manages the 4 push servers, and the mapping relationship stored in the task distribution server is expressed as: (push server 1, virtual classroom 1), (push server 2, virtual classroom 1), (push server 3, virtual classroom 2), (push server 4, virtual classroom 3). When the task distribution cluster expands, a task distribution server 2 is newly added in the task distribution cluster, then a push server 3 and a push service 4 are distributed to the task distribution server 2 for management, namely, the task distribution server 1 manages the push server 1 and the push server 2, the task distribution server 2 manages the push server 3 and the push server 4, then the sharing server pushes mapping relation information (push server 1, virtual classroom 1) and (push server 2, virtual classroom 1) to the task distribution server 1, and pushes mapping relation information (push server 3, virtual classroom 2) and (push server 4, virtual classroom 3) to the task distribution server 2.
S303, writing the updated mapping relation information into a local list.
The task distribution server writes the mapping relation information from the sharing server into the local list. The local list has a certain size of storage space, and when the storage space is insufficient when the mapping relation information is written, the mapping relation information in the local list can be deleted according to a certain rule, wherein the rule can be determined according to the storage time length and the query times of the mapping relation.
For example: the method comprises the steps that at most 100 pieces of mapping relation information can be stored in a local list of a task distribution server, when the mapping relation information of a sharing server is received, the task distribution server discovers that the storage space in the local list is insufficient when writing the mapping relation information into the local list, then obtains the storage time length and the query times of each piece of mapping relation information in the local list, the storage time length represents the time length from the moment when the mapping relation information is written into the local list to the current moment, the query times represent the queried times, then carries out weighted average on the storage time length and the inverse of the query times of each piece of mapping relation information to obtain an evaluation value, and deletes the mapping relation information with the evaluation value arranged in the preset quantity from the local list so as to be capable of successfully writing the updated mapping relation information.
S304, receiving a binding request message from the service console.
Before a student takes lessons, the student can access a service control console through terminal equipment to realize lesson reservation, the terminal equipment of the student sends a lesson reservation request message to the service control console, the lesson reservation request message carries the identification of a lesson reserved by the student, the service control console distributes virtual classrooms and lesson taking materials for the reserved lessons, then the service control console selects a task distribution server from a task distribution cluster and sends a binding request message to the selected task distribution server, and the binding request message carries the room number of the virtual classrooms and the material identification of the lesson taking materials. The virtual classroom is a virtual space for students to take lessons, and the students can receive media streams of the lessons and perform relevant interactions with teachers in the virtual classroom through the terminal equipment, for example: even wheat, chat or answer questions, etc. The lesson material is a file of a media stream of a passenger yard, the lesson material is generally a recorded broadcast video file, and the recorded broadcast video file of the application can be an AI video file with an interaction function.
For example: students select courses of the English of children through terminal equipment, a course about request message carrying identification of the courses is sent to a service control console, the service control console receives the course about request message from the terminal equipment of the students, the service control console allocates room numbers of virtual classrooms for the courses to be 11025, material identifications of the lesson materials allocated for the courses are 5812, and then the service control console obtains load state parameters of each task distribution server in a task distribution cluster, wherein the load state parameters include but are not limited to: CPU occupancy rate, disk occupancy rate, memory occupancy rate and plug-flow task number, then selecting the task distribution server with the lightest load from the task distribution cluster, and sending a binding request message to the selected task distribution server.
S305, a target push server is selected from the push cluster in response to the binding request message.
The task distribution server receives the binding request message from the sharing server, and because the task distribution server does not bind the push servers at this time, the task distribution server needs to select a target push server in an idle state from the push cluster, the number of the target push servers can be one or more, and the idle state indicates that the push task is not executed.
The selecting a target push server from the push cluster includes:
and selecting a target push server from the push cluster according to the polling mode. For example: the push cluster comprises 4 push servers, which are respectively: the task distribution server selects a target push server according to the sequence of the push server 1, the push server 2, the push server 3, the push server 4 and the push server 1 …. When the push server is currently required to be selected, the push server selected last time is determined to be the push server 1, and then the push server 2 is currently selected as the target push server. Or (b)
And selecting one plug-flow server with the lightest load as a target plug-flow server according to the load state parameters of each plug-flow server in the plug-flow cluster. For example: load state parameters include, but are not limited to: the CPU occupancy rate, the disk occupancy rate, the memory occupancy rate and the number of push tasks are used for selecting one push server with the lightest load from the push cluster as a target push server according to the load state parameters. Or (b)
And selecting one push server with the largest load capacity from push servers in an idle state in the push cluster as a target push server. Wherein the load capacity represents the maximum number of terminal devices that the push server can push.

The server identification is used for uniquely identifying the identity of the push server, the server identification comprises one or more of a domain name, an IP address, a port number and an MAC address, the task distribution server binds the server identification of the selected target push server with the room number of the assigned virtual classroom to generate mapping relation information, and the mapping relation information comprises the room number and the server identification.
S307, storing the mapping relation information in a local list.
The task distribution server writes the mapping relationship information generated in S306 into the local list. If the storage space in the local list is insufficient, a certain amount of mapping relation information may be deleted with reference to the description of S303.
And S308, pushing the mapping relation information to the sharing server.
The task distribution server pushes the mapping relationship information generated in S306 to the sharing server, where the sharing server stores the complete mapping relationship information generated on each task distribution server.
