Detailed Description
In the prior art, the interaction mode of the network topology view is to display the direct child nodes of the selected topology object layer by layer from the top to the bottom of the root node. Aiming at the defects of the multi-level single-path tree topology view in the prior art, the solution provided by the embodiments of the invention allows a user to view topology objects in a layered manner and can view all topology objects and link information in the same layer; meanwhile, a man-machine interaction mode of the topological view is improved, and user experience is improved.
The topology view in the embodiments of the invention is developed by using flex technology (certainly, Flash and JavaScript can also be used for development), is embedded in an html page for display, is played by a client by using a flashlayer or other playing software, supports complex man-machine interaction, and can monitor the actions of a user.
Fig. 2 is a schematic flow chart of an embodiment of a method for generating a network topology view according to the present invention, as shown in fig. 2, the method includes the following steps:
step 200, the network management system creates a corresponding number of topology object containers according to the hierarchy in the network and generates a plurality of topology objects;
the hierarchy in the network described in the embodiments of the present invention may include: the logical layer views are layered according to the hierarchical relationship of ' solution scheme ' -product ' -network element ' -node (dual computer or cluster) ', and the physical layer views are layered according to the hierarchical relationship of ' subnet ' -station-machine room ' -equipment '. The following embodiments are described by taking a three-layer network hierarchy of "product" -network element type "-node" as an example, but are not limited thereto. Specifically, the network management system creates three topology object containers according to three levels of the network. One level corresponds to one topological object container, which is realized by using an instance of a canvas control in flex, and each topological object container has corresponding topological level attributes which are used for distinguishing a plurality of different levels. After the network management system acquires that the network is divided into three layers, three corresponding topology object containers are created, and corresponding topology layer attributes are distributed.
The attributes of the topology object comprise basic attributes and extended attributes, and different attributes are stored in different tables. When the network management system creates a management object and then generates a plurality of topology objects by mapping, a hierarchical index attribute is added to the topology objects to indicate the hierarchy of the topology objects, and the hierarchical index attribute can be stored in an extended attribute table as the extended attribute of the topology objects.
Step 201, the network management system adds the topology object with the same hierarchical index attribute and the topology hierarchical attribute to a topology object container with the topology hierarchical attribute to generate a hierarchical topology view of a corresponding hierarchy;
when the network management system generates the topology objects, the hierarchical index attribute of each topology object and the topology hierarchical attribute of each topology object container are obtained, then all the generated topology objects are divided into the corresponding topology object containers, and specifically, the division rule comprises that the hierarchical index attribute of the topology object is the same as the topology hierarchical attribute of the topology object container in which the hierarchical index attribute is located. For example, if the topology level attributes of the created three topology object containers are "1", "2", and "3", respectively, the topology object with the hierarchical index attribute of "1" is added to the topology object container corresponding to the "product" level, the topology object with the hierarchical index attribute of "2" is added to the topology object container corresponding to the "network element" level, and the topology object with the hierarchical index attribute of "3" is added to the topology object container corresponding to the "node" level.
In the embodiment of the present invention, the topology object container includes all topology objects (not limited to a single solution or product) that should be presented at this level, and the topology objects are implemented by UIElement classes. When the topology view is initialized, all the topology objects are added into different topology object containers according to different levels, and the hierarchical topology view of the corresponding level is generated. The hierarchical topology view may include all the topology objects within the hierarchy, as well as the link relationships between the topology objects.
Further, in the embodiment of the present invention, topology objects in the hierarchical topology view corresponding to the adjacent upper and lower two levels are in a parent-child relationship. For example, the topology object in the topology object container corresponding to the "node" level is a "child node", the topology object in the topology object container corresponding to the "network element" level is a "parent node", and so on.
Step 202, after receiving a trigger command for displaying a target level, the network management system displays a hierarchical topology view corresponding to the target level on a user interface.
After the network management system generates each layered topology view, the layered topology views can be rendered into a visual user interface for display, and each layered topology view can be displayed respectively. If the user needs to switch the topology view, a trigger command which indicates that the layered topology view of the target layer is to be switched is sent to the network management system through a preset operation, and the network management system displays the layered topology view corresponding to the target layer on a user interface after receiving the trigger command for displaying the target layer. The target hierarchy may be an upper or lower level of the current hierarchy.
According to the method for generating the network topology view, which is provided by the embodiment of the invention, all hierarchical topology views including all topology objects in the hierarchy are generated, so that a user can view the topology objects hierarchically, all topology objects and link information in the same hierarchy can be viewed, the information presentation is richer and more intuitive, and the method is suitable for network management with a large number of devices and a complex link relation.
In an embodiment of the method for generating a network topology view, the generating a hierarchical topology view of a corresponding hierarchy includes the following steps: and the network management system determines the position area of the topological object according to the coordinate range defined by the automatic layout configuration file, determines the specific position in the position area according to the position attribute information of the topological object, and connects the topological objects according to the link relation after setting each topological object at the corresponding specific position to generate the hierarchical topological view.
Fig. 3 is a schematic diagram of a "product" object of a topology object hierarchy in the embodiment of the present invention, fig. 4 is a schematic diagram of a "network element" object of a topology object hierarchy in the embodiment of the present invention, and fig. 5 is a schematic diagram of a "node" object of a topology object hierarchy in the embodiment of the present invention, as shown in fig. 3 to 5, a topology view of a network system is divided into 3 different hierarchies, namely, a "product" layer, a "network element" layer, and a "node" layer, and at any different hierarchy, the topology view can display all topology objects at the hierarchy and link relationships between the topology objects. The topology objects are laid out in three hierarchical topology views according to an automatic layout configuration file, for example, topo _ layout.
The position attribute information (e.g., coordinate values) of the topology object is valid for a container of a specific hierarchy. By default, users of the system share one topology view, that is, the adjustment operation of the user on the position of the topology object will not be saved in the database, and the topology object will recover the automatic arrangement layout each time the topology view is opened. The information of the extended attribute table, the automatic layout configuration file, the position attribute information of the equipment and the like can be stored in the database.
In the embodiment of the method for generating the network topology view, the invention also provides a flexible topology view switching mode, wherein the first mode is to click and adjust the scale for switching, and the second mode is to switch by rolling the mouse wheel. The essence of the topology view level switching is that the topology object container representing the original view level is hidden, and the topology object container representing the new view level is displayed.
For the first way, the trigger command in the above method embodiment may be generated by clicking or dragging a scale on the user interface. Correspondingly, the target level is determined by clicking a direction button of the scale; the positive button corresponds to the previous level, and the negative button corresponds to the next level; or the target level is determined by the dragging direction of the scale; the positive dragging corresponds to the previous level, and the negative dragging corresponds to the next level.
In the screen area with the same size, the upper layer topology view only has fewer parent topology objects, the lower layer topology view has more child topology objects, and the user can feel the zooming effect of the topology view by the aid of the frame change which represents the area range occupied by the topology objects. Clicking the scale by a mouse, triggering a view level switching event, and displaying different contents by a program according to the currently displayed level and the clicked switching type (switching to an upper layer or a lower layer).
For the second way, the trigger command in the above method embodiment may be generated by rolling a mouse. Correspondingly, the target level is determined by the rolling direction of the mouse; scrolling up corresponds to the previous level and scrolling down corresponds to the next level.
The topology management interface establishes a mouse event monitor mouseWheelListener and a corresponding event processing method mouseWheelEventHandler for monitoring a mouse wheel rolling event and recording a position p (stagEX, stagY) of a mouse when the event occurs. The mouseWheelEventHandler method is triggered when a listener receives a mouse wheel event on a topology view. The mouseWheelEventHandler method firstly determines the current position information of a mouse, and takes the position p as a central point of view level switching. And then judging the rolling direction of the mouse roller to determine whether the switching is to the upper layer or the lower layer, firstly setting the attribute visible of the layered topology view of the current layer as false, and then displaying the layered topology view to be displayed. And calculating the coordinate offset of the topological objects in the new hierarchical view while switching, so that each topological object is displayed at a correct position. Due to the limitation of the size of the user interface, a partial view or a full view of the hierarchical topology view corresponding to the target hierarchy can be displayed on the user interface. In this embodiment, the visible attribute of the hierarchical topology view is set to implement hiding or displaying, and the method is also applicable to the first method.
In addition, the grouping mode of the nodes and the default display hierarchy can be customized according to the requirements of customers. Key Performance Indicators (KPIs) and alarm states of topology objects in the topology views support upper-level convergence, and any layer of topology views is realized to display the running state of the whole network equipment.
By applying the method provided by the invention, a user can monitor the topological structure and the running state of the whole network equipment through the topological management overall situation, once an alarm is found, the equipment with the problem can be quickly positioned by rolling the mouse and the roller wheel, so that the efficiency of maintenance personnel is greatly improved, and the user experience is good.

The creation module 71 is also responsible for generating a plurality of topology objects having hierarchically indexed properties. Specifically, when a plurality of topology objects are generated by mapping after the management object is created, the creating module 71 adds a hierarchical index attribute to the topology object to indicate a hierarchy to which the topology object belongs, and the hierarchical index attribute as an extended attribute of the topology object may be stored in the extended attribute table. The generating module 72 obtains the hierarchical index attribute of each topology object and the topology hierarchical attribute of each topology object container, and then divides all the topology objects generated by the creating module 71 into the corresponding topology object containers, specifically, the division rule includes that the hierarchical index attribute of the topology object is the same as the topology hierarchical attribute of the topology object container in which the topology object is located, and the topology objects in the hierarchical topology views corresponding to the adjacent upper and lower two hierarchies are in a parent-child relationship. After the generation module 72 generates each hierarchical topology view, the display module 73 may render it into a visual user interface for display, and may also display each hierarchical topology view separately.
