Embodiment 1
[0048] Such as figure 1 As shown, the present invention proposes a kind of DSE optimization method based on K-NN algorithm, and this method comprises:
[0049] S1: Build a TSN network model including communication nodes, and configure scheduling priorities for traffic levels in the TSN network model;
[0050] S2: Based on the data in the training set, the K-NN algorithm that replaces the traditional algorithm in DSE to perform schedulability analysis is trained according to the configured scheduling priority, and the node ratio value that meets the requirements is obtained;
[0051] S3: compare the node proportion value with the preset threshold value, if the node proportion value is less than the preset threshold value, use the K-NN algorithm, if the node proportion value is greater than the preset threshold value, use the traditional algorithm in DSE, for the preset Adjust the size of the threshold;
[0052] S4: Repeat the content of S3 based on the adjusted preset thresho...
