[0280] Step 1: End-to-end display of internal active equipment topology: Set all paths from the A-end network element to the Z-end network element in the transmission service internal simulation module as visualization paths, and add event pop-up windows to the internal 3D model basic components on the visualization paths to display the device appearance and internal slot panel status of the internal 3D model basic components;

When generating the topology between devices, the color can be used to distinguish whether it is an intra-domain topology connection or a cross-domain connection. In addition, the network element icon shape and color can be used to distinguish different device types and device status. Through this layer of 2D window, it can be intuitively displayed whether there are faulty devices and faulty cables on the working path protection path from A to Z, how many manufacturers' equipment there are, and how many types of equipment for each manufacturer; for each device in the path, add an event pop-up window to display the 3D model of the device, showing the appearance of the device, the internal slot panel status,

[0282] Step 2: Display of cross-connections inside the device: Add an event pop-up window for the internal 3D model basic components on the working path and protection path in the visualization path to display each route information that the circuit has traveled through in the internal 3D model basic component;

[0285] Through the working path and protection path shown in 5.1, for each topological connection, add an event pop-up window to visualize which optical cable segment is actually used by the route in a 3D model (using Three.js technology), display the optical cable information, and drill down to see which fiber cores in the optical cable are currently in use. The fiber cores in use are distinguished by color, and the fiber core number information is dynamically displayed.

[0295]

[0296] Step 2: Alarm event simulation and display

[0297] a. Alarm management simulation is divided into active alarm management and historical alarm management. Active alarm management generates an alarm list in real time through websocket technology push and displays it. The alarm list adds alarm processing events including: view, confirm, clear, de-confirm, and alarm reversal. At the same time, engineering alarm configuration and dispatch rule configuration events are added;

[0298] b. Add a pop-up window to the alarm list to view events, and a 3D model to show the current alarm display on the device;

[0299] c. On the visualization page of the topology management view, event trigger alarms are added for network elements, boards, and ports respectively. The generated alarm titles are derived from the collected manufacturer alarm lists. When an alarm is generated, the topology page color immediately distinguishes and displays the alarm effect. At the same time, for circuit services carried by the upper layer, if the working and protection paths are interrupted, the circuit interruption status is dynamically updated through automatic calculation, thereby achieving the goal of simulating and displaying the effect of the alarm affecting the business scope.
