This application provides a network channel routing verification method and apparatus. The method constructs a directed graph based on the directed connection relationships of ports in the routing data, and uses graph algorithms to partition connected components and add audit rules based on data dimensions for verification. This allows for rapid and accurate detection of the connectivity and integrity of channel routes. During the verification process, it does not rely on the segment group order attribute in the routing data, avoiding shallow data quality issues that could prevent verification. Furthermore, it can verify the integrity of the channel carrying structure according to the business channel dimension, quickly aggregating all hierarchical channel routing anomaly audit results. For business channels with abnormal aggregated audit results, a secondary verification is performed to ensure the accuracy and reliability of the verification results. This helps vendors rectify data according to the business channel dimension and achieve rapid results.
