TSN network time-aware shaper modeling method based on network calculation

The invention provides a TSN network time aware shaper modeling method based on network calculation, and the method comprises the steps: setting a central node server in a plurality of network nodes of a network communication environment, and dividing a data flow to be received on the central node according to the characteristics of the data flow; calculating an arrival curve of each to-be-received data stream, wherein the arrival curve is used for carrying out cumulative modeling on the input flow reaching the central node; service curves of different data streams are calculated and used for modeling data sending services which can be provided by the central node server; and calculating the delay upper limit D of the data stream when the data stream is constrained by the curve alpha (t) and passes through the node with the service curve sigma (t). The smaller the time delay is, the stronger the data transmission capability of the time sensing shaper is, and the better the data transmission capability is; oth
