Traffic from a remote endpoint of an enterprise is processed by a cloud-based module performing a security service, such as SWG, ZTNA, or CASB. The traffic is forwarded back to a server of the enterprise for transmission over a leased line to a destination endpoint. The remote endpoint, cloud-based module, and server may be in a first jurisdiction and the destination endpoint may be in a second jurisdiction such that cross-border controls are performed more efficiently by a provider of the leased line.

This invention provides a method and system for implementing a dedicated line client based on the Electron framework, comprising: upon client startup, detecting whether a configuration file is located in the same directory as the running executable program; using the `onBeforeRequest` method in the Electron framework's session to intercept requests; rewriting the original request using the Electron framework; after receiving the rewritten request from the client, the user-side dedicated line server sends it to the server-side dedicated line server; the server-side dedicated line server uses an Nginx reverse proxy to restore the user-side request and initiate a final request to the corresponding application server; returning the response result of the final request to the original path and adding a cross-domain header to the response. This invention uses a reverse proxy to achieve the purpose of the dedicated line server initiating requests to the application server, ensuring high performance, stability, and security, and exhibiting strong performance.

This invention discloses a cloud network scenario-based diagnostic platform based on decision trees for end-to-end full-link network diagnosis. Addressing the root cause diagnosis problem when tenant end-to-end traffic anomalies occur, this invention proposes a multi-node full-link network diagnostic scheme based on decision trees. It designs decision logic based on expert experience, solving the decoupling and judgment of complex decision logic through root cause judgment with multiple combinations of conditions. It transforms the original independent condition judgments into state machine-based judgments, overcoming the challenges of long access links, numerous anomaly information, and difficulty in comprehensive root cause judgment faced by traditional diagnostic technologies. This diagnostic platform can be deployed on large-scale production cloud network operation and maintenance platforms and can be widely applied to the anomaly diagnosis of various network components such as virtual private networks, public network access, load balancing, and leased line access.
