The solution of the present invention is further described below with reference to a specific application scenario example. The following is a description of the solution of the present invention by establishing a course as an example. The scheme for establishing two or more courses is the same as the above, and will not be described again.

Embodiment 1:

The system and method of the embodiment require the network e-learning initiator and the receiver to access the same network.

The system and method of the present embodiment need to separately install a teacher client and a student client on the teaching electronic device (such as a personal computer) used by the network e-learning initiator and the receiver, and all clients are configured with the same multicast. Address I1 (first multicast address) and port number P1 (first port number). As shown in FIG. 4, after the above network access configuration is completed and the client is installed, the present invention will be implemented by the following scheme:

Step 1: The teaching initiator starts the teacher client, sets a unique class number, and then binds the multicast address I1 and the port number P1 and starts broadcasting the class number periodically;

Step 2: The teaching receiver starts the student clients A and B, inputs the same class number as the teaching initiator, and then binds the multicast address I1 and the port number P1 and starts waiting to receive the class number broadcast sent by the teacher client;

Step 3: When the student number received by the student client is the same as the class number entered when starting the game, the broadcast is added to the class (Class 1), and the teacher client receives the broadcast after joining the class. The client is placed in the class student list to generate a first student list;

Step 4: When the teaching initiator is ready to start a teaching course (Course 1), select the designated member (one or more or all) in the class student list (first student list) through the teacher client and bind the course. (Course 1) Corresponding new multicast address I2 and port number P2, and then the course name, the selected student list, and the new multicast address I2 bound to the course through the original multicast address I1 and the first port number P1. Port number P2 is broadcasted;

Step 5: All classroom students will receive this course broadcast, but only when they find themselves in the student list of this course, the student client joins the new multicast address I2 and port number P2 bound to the course. And receive the course content in this new multicast address I2 and port number P2, and then complete the course teaching; (of course, the teaching initiator can start multiple simultaneous The same course, each course can choose different classroom students, each course is bound to a different multicast address and port number. )

Step 6: When the teaching initiator ends the teaching of a certain course, the teacher end will send a course end notification at the original multicast address I1 and port number P1, and the student client receiving the notification matches the course and releases the pair. Binds to the multicast address I2 and port number P2. (Of course, during the course of the course, the teacher client can also specify to delete a student. After receiving the deletion broadcast, the student client releases the binding to the corresponding multicast address I2 and port number P2.)

Through the above steps, the system and method can realize effective management of classroom students, and students can be designated to participate in designated courses at any time. Each course is bound with a different multicast address and port number, and the designated student is bound to the course. Multicast address and port number. This can fully and accurately utilize network bandwidth resources, greatly reducing the load on the switch.

Embodiment 2:

As shown in FIG. 5, it is a schematic flowchart of the implementation scheme of the system and method, and the specific process is as follows:

S01: the teacher and the student client A and B respectively bind the classroom multicast address and the port number (the first multicast address and the first port number);

S02: the teacher client broadcasts the class number;

S03: The class number received by the student client A is consistent with the configuration of the user, and the broadcast response is added to the class (class 1). After receiving the response broadcast, the teacher client puts the student client A into the student list (the first student) List;

S04: The class number received by the student client B is consistent with the configuration of the user, and the broadcast response is added to the class. After receiving the response broadcast, the teacher client puts the student client B into the student list (the first student list);

S05: The teacher client creates a new course (course 1), binding the course multicast address and port number;

S06: The teacher client selects student A to participate in this new course, and issues a course broadcast in the classroom multicast with the course name, student list, and course multicast address and port number;

S07: After receiving the course broadcast message, student client A finds that he or she immediately binds to the multicast address and port number of the course in the student list of the course;

S08: The teacher broadcasts the lecture content data in the course multicast (course 1), and the student A receives the course content data in the course multicast;

S09: The teacher client informs the end of the course in class multicast (class 1), and disconnects the course multicast. Student client A also disconnects the course multicast after receiving the broadcast notification. .

The goal of the system and method is to effectively manage network e-learning members, facilitate grouping and control, accurately assign designated members to one or more teaching content, and effectively manage access devices used by teaching members, thereby significantly Improve teaching efficiency and network utilization.

In another embodiment, software is also provided for performing the technical solutions described in the above embodiments and preferred embodiments.

In another embodiment, a storage medium is further provided, wherein the software includes the above-mentioned software, including but not limited to: an optical disk, a floppy disk, a hard disk, an erasable memory, and the like.

While the embodiments of the present invention have been described above, the described embodiments are merely for the purpose of understanding the invention and are not intended to limit the invention. Any modification and variation in the form and details of the embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention. The scope defined by the appended claims shall prevail.
