Abstract

The present invention provides an intelligent routing method of an information transmission platform and a corresponding system. Firstly, the effectiveness of channels between adjacent nodes is calculated, and the importance of each network node in network information transmission is calculated through the principle of structural holes. According to This selects one type of key nodes and two types of key nodes, and selects available channels and unavailable channels according to channel validity; finds the transmission path between two non-adjacent network nodes according to the key nodes, and the transmission path should contain at least A first-class key node, and does not contain any second-level key nodes; at the same time, the path itself can be adjusted and classified according to the types of channels contained in the path. Through the above method, the original search for the shortest path can be changed to the path with the best transmission effect, and multiple paths can be provided at the same time, so that a suitable path can be selected according to the network status, which greatly improves the quality and efficiency of data transmission .

Description

technical field [0001] The invention belongs to the technical field of routing strategies, in particular to an intelligent routing method and system for an information transmission platform. Background technique [0002] At present, information transmission through the network has become the most important way of information transmission. The network can be used to transmit various forms of file data such as text, images, software, audio, and video. Since audio and video files are often superimposed by multiple formats, with large capacity, various contents, and complex formats, the transmission quality and efficiency of such files largely depend on the quality of the network environment, making the transmission path and transmission method The choice of will greatly affect the effect of transmission. Currently, in an overall network, the quality of a transmission path is often judged by the length of the transmission path. However, affected by the nature of different nod...
