When the pushing operation executed by the pushing server which is currently operated is abnormal, the next server in the target pushing server list is replaced in time to conduct pushing, and the like, so that smoothness in the pushing process is ensured.
After the push is completed, the total server can realize the sharing operation of the acquired push related data in each push server.
S160, if the push condition is not abnormal, a pull request is acquired.
In this embodiment, the streaming request refers to a live broadcast request initiated by a live broadcast client held by a student, where the streaming request includes a region where the live broadcast client is located and network operation information of the live broadcast client.
S170, sorting the streaming servers in the preset streaming server list according to the streaming request to obtain a target streaming server list.
In this embodiment, the number of preset pull-stream server lists is several, and each preset pull-stream server list has a corresponding service area, that is, is only used for coping with a pull-stream request in a certain area, so that the phenomenon that the processing capacity of the server is uneven can be avoided, that is, the problem that the pull-stream request is concentrated to a certain pull-stream server for processing at any position to cause server breakdown can be avoided.
In this embodiment, the target streaming server list refers to a preset streaming server list that is closest to the region from which the streaming request originates and ordered in a manner of strong to weak network connectivity.

Fig. 5 is a flow chart of a live communication method according to another embodiment of the present invention. As shown in fig. 4, the live communication method of the present embodiment includes steps S210 to S340. Steps S210 to S300 are similar to steps S110 to S200 in the above embodiment, and are not described herein. Steps S260 to S270 added in the present embodiment are described in detail below.
S310, grouping the live clients;
s320, acquiring an interaction request from a live client;
s330, sending the interaction request to the push client, and acquiring reply content corresponding to the interaction request of the push client;
and S340, the reply content is sent to the live client to be displayed on the live client.
If large-scale live clients are to interact, the live clients need to be grouped first. The manner of grouping includes two types, one is to create the grouping in advance, one is to create the grouping randomly,
the grouping is created in advance, and student information such as schools, grades, classes and the like is input into the system in advance, and then students are grouped according to various rules, namely, group by group, grade by group, school by group and the like. The random group creation is to set the maximum number of people in each group in the system, and when the students enter the living broadcast room, the students can judge whether the current group number is full, and if so, a new group is dynamically created.
Students can watch live broadcast after entering the live broadcast room and can speak inside the group. Because the number of the speaking people is large, the speaking contents are messy, the chat contents can be audited and managed by the master server, after the students speak, the students can see the information in real time at the respective terminals after the audits pass, and the master server provides the following processing modes: answering the student questions, maintaining the class discipline, and sending the student questions to a teacher, wherein the teacher can interact with the students after seeing the information; chat content violations are immediately deleted; disabling the students; the group is disabled.
The teacher can record the questions which need to be answered by the student when the teacher is in class into the push client before the teacher is in class. The answering function can be started in the course, and the answering message is sent to the live client. After receiving the answer message, the live client displays the question information in the live client, and the students can fill in the answer and submit the answer. Because of the large number of live viewers, submitting answers at the same time can place very high stress on the overall service. The total server does not process the information immediately after receiving the information, and caches answers submitted by students, and processes the answers in batches every five seconds. The teacher end can see the statistical information of the student answer questions, and the statistical information is updated every five seconds. Students can be divided into learning groups in the course of lessons, and students can use characters to interact with each other in the groups. All groups are managed by a total server, the problems of students are solved, the order of courses is maintained, chat contents are managed and the like, a teacher can issue questions in the course of teaching, the students answer online in real time, and the teacher can see statistics of the situation of the students doing questions, so that the teaching flow is assisted to be optimized.
For example: in the epidemic situation of spring festival in 2020, in order to respond to the call of "listening class without stopping school", the product provides free online live course for all students in China. The shou mountain 70 university totals about 7 tens of thousands of students taking part in the course, using a mobile phone or computer at home, to watch on-line live courses, as recommended by the shou mountain education bureau in Hangzhou city. In order to support large-scale users to carry out online live broadcast watching, 10 pull stream servers are deployed in a Shore area before the product starts to play lessons and serve as edge nodes to provide pull stream service. And then grouping all students according to the school and grade according to student information provided by the school, wherein the students can perform text interaction in the group. The teacher can prepare a plurality of questions in the course of teaching to enable students to answer online, and after the students finish answering and submit the questions, the teacher can see the answering condition of each student and the overall statistical information of the questions, such as the number of submitted people, the accuracy, the error rate and the like. 9 teaching aids are arranged in the management background to manage group contents and students, questions presented by the students can be directly answered in the group if the teaching aids can answer, the questions of the students can be sent to a teacher if the questions cannot be answered, and the teacher can answer the questions in a live broadcast process after seeing the questions of the students. If a student sends information irrelevant to teaching content in a group, the teaching aid can delete the information or directly set the student to prohibit speaking. In addition, some school teachers also require the teaching aid to set the whole group to be forbidden to speak, so that students can concentrate more when in class.
Fig. 6 is a schematic block diagram of a live communication device 300 according to an embodiment of the present invention.
