The embodiment of the present invention takes the OMMB network management system as an example, and proposes a method for displaying a topology rack diagram based on the network management system, which brings a good display effect to the physical topology rack diagrams of PB and pRRU in particular.

In this embodiment of the present invention, the implementation process will be described in detail by taking the example of showing the topology rack diagram of the networking access architecture BBU-PB-pRRU on the basis of the OMMB network management system, and the actual connection of the BBU-PB-pRRU topology rack. The relationship is shown in Figure 3.

The first step, physical device modeling:

Physical device modeling is carried out based on the management object model MOM, and the interface of the OMMB network management system supports the configuration of BBU, PB, pRRU and the boards under the above devices in a tree structure.

The second step, the connection configuration of the device model:

Figure 4 shows a schematic diagram of the relationship between the upper and lower levels of the connection configuration on the network management system interface through the MOM modeling of the fiber cable and the Ethernet interface.

To implement the second step, you can manually configure it on the interface of the network management system or import it into the OMMB network management system after configuring it through the planning template. The OMMB network management system configuration framework will generate a set of configuration data as the basis for displaying the topology rack diagram. So far, the basic data of this invention has been prepared.

The third step is to perform physical topology and coloring display according to the building:

After constructing the physical device model and completing the connection configuration, the following is the realization effect diagram and detailed description of the key points of the design:

Specifically, after entering the topology management interface, the tree structure on the left shows the information of each location under a subnet, that is, a certain area, and the overall location and site information map is displayed on the right.

After entering any location site to present the details, the interface is shown in Figure 6. The BBU, PB, and PRRU included in the equipment in this location site are displayed in one interface. The specific implementation content is as follows:

The buildings in the site at this location are represented by boxes, the floors are separated by horizontal lines in the building boxes, and one row represents one floor; BBU is represented by a rectangular box, PB is represented by a rectangular box, and Bop veneer is built in the PB. pRRU is represented by a three-layered oval ring, and PB is represented by a double-layered rectangular ring.

The detailed interface of the location site of the network management system provides three display modes: overview display, board status display, and community relationship display.

When the mouse is close to the pRRU, the floating frame displays the PB number connected to the pRRU and the electrical port number connected to the PB. pRRUs are arranged vertically on different floors of the same building, with a maximum of 8 pRRUs placed on each floor, and horizontally arranged in different buildings. The pRRU is represented by an ellipse, and there are three rings in total, which respectively identify the alarm state, the cell merging relationship, and the state associated with the PB from the inside to the outside. When there is an alarm in the pRRU, the inner circle will display a red alarm; if the pRRU with the alarm is selected, the outer circle of the corresponding connected PB will be highlighted in green, and the inner circle will display a red alarm; after selecting the pRRU, click the right mouse button to export the construction drawing of the pRRU , as shown in Figure 7, which also includes the number of the pRRU, so that it is easy to find the very specific orientation of the pRRU in the building, which is convenient for finding equipment and accelerating fault location. When you click to select a pRRU, the outer ring of the pRRU will be highlighted in green, and its corresponding connected PB will be highlighted in green. Click again to cancel the highlight.

2) When selecting the board status display mode: Take PB as an example, the PB has a built-in BOP board. At this time, the inner circle of the PB panel indicates the operating status, normal is green, and the fault is red; the outer circle indicates the manual state: blocked is yellow , unblocked in blue.

3) When the cell relationship display mode is selected: Figure 6 shows the cell merging relationship between pRRUs very intuitively, that is, the color display of the second ring, the same outer circle color indicates the pRRUs configured in the same logical cell, right click to select Cell configuration, directly enter the cell parameter configuration page. For pRRUs in the same cell in the mouse circle, click the right mouse button to directly perform cell split configuration, such as modifying the logical cell number in the cell relationship information of some pRRUs, that is, to determine which cell the pRRU belongs to, and select any two cells Cell combination configuration can be performed directly.
