Topology display is one of the most important functions in a network management system.
With the development of internet and Web technologies, network management systems increasingly support B/S (browser/server mode) architecture. In some application scenarios, the operator no longer only needs to show one conceptualized logical topology, but rather wants the topology to be combined with a map so that the device is accurately shown on the map according to the actual geographic location.
When the number of the topological nodes (devices) is too large, too many topological nodes are drawn on the map at one time, pressure is generated on the drawing of the Web front end, the response of the front end is too long, and the interface is in a false dead state. In addition, the smaller the map scale is, the larger the display range of the displayed map in a unit area is, the lower the precision is, the closer the topological nodes are, and even the partial or complete overlapping situation occurs. When a large number of devices of an operator are in the same machine room, the devices are completely overlapped on a map no matter how large the scale is adopted due to the same geographic position of the devices.

The embodiment of the application provides a map-based topological node display method, which comprises the steps of determining the size of a scale for displaying a map, virtualizing all topological nodes in a corresponding area into a virtual area node by taking the level of the area corresponding to the scale as a unit, displaying the virtual area node at the position corresponding to the map, virtualizing a link with the same source end and sink end into a virtual link due to the fact that the topological node is virtualized into a virtual area node, and displaying the virtual link at the position corresponding to the map. The scheme can quickly load and present the topological nodes on the map according to the map displayed by different scales.
The topology node display device based on the map in the embodiment of the application can be a piece of equipment with a data processing function, such as a PC.
The following describes in detail a process for implementing map-based topological node display in an embodiment of the present application with reference to the accompanying drawings.
The following setting is performed in advance before the topological node display is performed:
setting a corresponding relation between the interval range of the scale and the region level;
the range of the first scale interval corresponds to a first area level;
the range of the second scale interval corresponds to a second area level;
the interval range of the third scale corresponds to a third area level;
the range of the fourth scale interval corresponds to the fourth zone level;
setting the corresponding relation between the region levels and the regions:
the first area level corresponds to a plurality of first areas in units of the first area level;
the second area level corresponds to a plurality of second areas in units of the second area level;
the third area level corresponds to a plurality of third areas taking the third area level as a unit;
the fourth area level corresponds to a plurality of fourth areas in units of the fourth area level.
Wherein, the first and the second end of the pipe are connected with each other,
the range of the first scale interval is [0, M);
the range of the second scale interval is [ M, N);
the range of the third scale interval is [ N, T);
the range of the fourth scale interval is [ T, + ∞ ];
wherein T > N > M >0.T, M and N are values greater than 0.
In the embodiment of the present application, taking setting of four scale interval ranges as an example, the first area level, the second area level, and the third area level may be respectively: province, city, district; the fourth zone level is the actual physical location, (the first zone is the physical zone corresponding to each province, the second zone is the physical zone corresponding to each city, the third zone is the physical zone corresponding to each district, and the fourth zone is the physical zone corresponding to each physical location).
The three-level area may be equally divided according to the actual physical location, for example, a map may be equally divided into a plurality of first areas in units of a first area level, each first area may be equally divided into a plurality of second areas in units of a second area level, each second area may be equally divided into a plurality of third areas in units of a plurality of third area levels, and each third area may be equally divided into a plurality of fourth areas in units of a plurality of fourth area levels.
In the embodiment of the present application, the number of the region levels is not displayed, and the division manner of the regions is not displayed, and the two division manners are only examples.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a map-based topological node display process in an embodiment of the present application. The method comprises the following specific steps:
And 102, determining the regional level for displaying the topological nodes on the map according to the scale.
And determining the area level corresponding to the scale of the currently displayed map according to the corresponding relation between the set scale interval range and the area level.
Virtualizing all topology nodes in the area corresponding to the area level into a virtual area node;
and when the area level is a fourth area level, virtualizing the topological nodes in the same geographic position as a virtual area node.
When the area level is a first area level, a second area level or a third area level, all the topology nodes in each area corresponding to the area level are virtualized as one virtual area node, and if there are multiple topology nodes in the same physical location, the same virtual area node is necessarily virtualized.
And step 104, virtualizing a link with the same source end and the same destination end into a virtual link according to the node information of the virtualized virtual area node, and displaying the virtual link at the position corresponding to the map.
Because a plurality of topological nodes are virtualized into a virtual area node, a plurality of original physical links may be different, but the nodes are virtualized to cause the same connecting links, and the plurality of physical links are virtualized into a virtual link and displayed on the corresponding position of the map.
The following describes a schematic diagram of topology node virtualization in the embodiment of the present application, taking a specific topology as an example, with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating topological node display when a map is displayed according to a fourth scale. In fig. 2, 6 topology nodes are taken as an example, and a large number of topology nodes may be included in practical application, and only 6 topology nodes are taken as an example here; and if the topological nodes 1 and 2 are located at the same geographical position, the topological nodes 1 and 2 are virtualized to be an area node and displayed at the corresponding physical position of the map on the premise that the map is displayed on the fourth scale.
If a connection link exists between the topology node 1 and the topology node 2, the connection link is not displayed when the topology node is displayed, and the connection link is displayed only when a user needs to acquire the information of the topology node in the virtual area node.
When the topological nodes are displayed on the map displayed on the fourth scale, if a plurality of topological nodes do not exist at the same physical position, all the topological nodes are directly displayed on the map, and virtual display of the topological nodes is not required.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a map divided into regions at a third region level when the map is displayed on a third scale.
The area division shown in fig. 3 is only an example of four third areas (third area a, third area B, third area C, and third area D) divided in units of areas when implemented, and the area division is not clearly shown on the map.
According to the topology node display method implemented in the embodiment of the present application, a plurality of topology nodes exist in each of the third area a, the third area B, and the third area C, and all the topology nodes need to be respectively displayed virtually, specifically:
the topology node 1 and the topology node 2 in the third area A are virtualized to be a virtual area node A;
the topology node 3 and the topology node 4 in the third area B are virtualized as one virtual area node B
The topology node 6, the topology node 7, and the topology node 8 in the third area C are virtualized as one area node C.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating topology node display when the map is displayed according to the third scale in fig. 3. As shown in fig. 4, only one virtual area node, or one topology node, is displayed for each third area.
Some links are not displayed on the map due to the virtual nodes, such as the link between the topology node 3 and the topology node 4, the link between the topology node 6 and the topology node 8; for some links, because the topology node is virtualized to a virtual area node, it is necessary to virtualize the physical link as a virtual link, for example, the link between the topology node 4 and the topology node 6, and the link between the topology node 4 and the topology node 7, for example, the link between the virtual area node B and the virtual area node C in fig. 4.
The topology nodes displayed on the map and the virtual area nodes store corresponding node information, such as node identifiers of the topology nodes and connection conditions with other topology nodes, namely related link information; the node information corresponding to the virtual area node includes: the virtual area node includes an identification of the topology nodes, and link connection conditions between each topology node and other topology nodes.
Based on the above implementation, the virtual area nodes in the embodiment of the present application may also perform the same-layer display, which is specifically implemented as follows:
when a request for expanding the virtual area nodes is received, displaying the information of all the topological nodes in the virtual area nodes and the link information taking the topological nodes as source ends or destination ends on the map.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating nodes of the expanded virtual area on the map shown in fig. 4. In fig. 5, taking the request for expanding the virtual area node C as an example, it is shown that the virtual area node C includes the topology node 6, the topology node 7, and the topology node 8, and displays the corresponding link information on the map.
When the virtual area nodes are expanded in the embodiment of the application, the nodes are expanded in the same layer, which specifically includes:
when the virtual area nodes are expanded and displayed, the scale of the current map display is not changed, all expanded topology nodes and link information are drawn near the virtual area nodes, and the dependency relationship between the topology nodes and the virtual area nodes is expressed in a manner similar to that of labels, which is a display example manner, and the specific implementation is not limited to the display manner.
After the virtual area node is expanded, the virtual link (if existing) originally connected to the virtual area node is not drawn any more, but is replaced by one or more expanded actual links.
In summary, the topological display data are optimized according to the scale and the geographic position of the topological nodes, the front-end topological loading and drawing speed is accelerated, the overlapping of the topological nodes is reduced, and all the topological nodes can be clearly presented on a map.
