Embodiment Construction

[0035] The technical solutions of the present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0036] The present invention needs a node registration server to maintain and notify the status of nodes in the dynamic binary tree.

[0037] The rules of the dynamic binary tree need to be dynamically updated in real time according to the situation of the nodes in the system. The joining and exiting of nodes affect the rules of the dynamic binary tree. At the same time, the notification time of the node status determines the frequency of dynamic binary tree rule changes.

[0038] The organization method of dynamic binary tree rules is to organize into a balanced binary tree according to the node numbers in the system from small to large. The number starts from 0, as the root node, or called node 0 (the node numbered 0). When node n (the node numbered n) is added, the node is added according to the rules of bal...

Abstract

The invention discloses a data transmission method based on dynamic binary tree child-grandson two-channel in an internet classroom. Nodes of the binary tree are divided into logical relationships of father and child as well as grandfather and grandson according to the levels of the nodes, and data are transmitted among the nodes with the logical relationships of father and child, grandfather andgrandson and the like in parallel at the same time. In the method, the nodes which enter and exit the binary tree are sequentially numbered, and the binary tree structure is dynamically organized, thus realizing regulation update of the dynamic binary tree in the transmission process. By adopting the technical proposal of the invention, data transmission is carried out based on the dynamic binarytree child-grandson two-channel, thus reducing data traffic of the single node and solving the problems of bandwidth occupied by the data transmission in the internet classroom and stability of the transmission.

Description

technical field [0001] The invention relates to the technical field of data transmission in Internet classrooms, in particular to a data transmission method based on a dynamic binary tree in Internet classrooms. Background technique [0002] Internet classroom is a multi-user network communication application applied in the Internet environment. Data transmission technology needs to solve the problem of data transmission between multiple points. At the same time, due to the nature of the application, it is required to achieve high real-time performance and high reliability in transmission. [0003] The most common data transmission method is the transmission method of star broadcast. In the star broadcast method, the root node is the center of the star structure, and other nodes are directly connected to the root node. The transmission of data is broadcast by the root node to each node. [0004] The advantage of this method is that the architecture is simple, and the fai...
