Problems solved by technology

During the interaction process, the teacher can send data packets to a group of students. The integrity is not too high, and data packet loss is prone to occur.
In the actual classroom, the two interactive modes of the teacher and the students bring great worries and troubles to the teaching, and it is difficult to meet the classroom implementation and accuracy interaction requirements

Abstract

The invention discloses a reliable data transmission method between a teacher terminal and a student terminal. The transmission mode is selected according to the amount of interaction, that is, multicast is selected when the amount of interaction is large, and unicast is selected when the amount of interaction is small. For the problem of incomplete data caused by multicast, the self-inspection retransmission mechanism is used to determine the packet loss or error packet caused by multicast, and the packet loss or error packet is retransmitted in unicast mode, thus effectively combining multicast and unicast , give full play to their respective advantages, and at the same time meet the requirements of real-time transmission in the classroom and the integrity of data content, and improve the interactive experience in the classroom, especially suitable for the wireless network environment in the classroom.

Description

technical field [0001] The invention belongs to the technical field of educational informatization, and more specifically relates to a reliable data transmission method between a teacher terminal and a student terminal in a classroom. Background technique [0002] With the development of educational information technology, more and more classrooms use smart terminal devices for classroom interaction. At present, there are usually two ways to interact between the teacher end and the student end: first, point-to-point transmission through unicast. During the interaction process, there may be many users on the student end, and the student end often needs to wait in line to receive the data stream from the teacher end, so the real-time transmission of data cannot be guaranteed. Second, point-to-many transmission is carried out through multicasting. During the interaction process, the teacher can send data packets to a group of students. The integrity is not too high, and data ...
