[0001] This application claims priority to Chinese patent application No. 202310798719.3, filed on June 30, 2023, entitled “Method, device, apparatus and computer-readable storage medium for displaying topological information,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a method, apparatus, device, and computer-readable storage medium for displaying topology information. Background Art

[0003] With the development of communication technology, the information involved in the communication process is becoming more and more diverse and the amount of information is also increasing. For example, topology information can be presented through network topology. Therefore, it is possible to determine the topology information that needs to be displayed and display it accordingly to meet the user's need for obtaining topology information.

[0004] Summary of the Invention

[0005] This application provides a method, apparatus, device, and computer-readable storage medium for displaying topology information to display more comprehensive topology information. The technical solution is as follows:

[0006] In a first aspect, a method for displaying topology information is provided, the method comprising: obtaining topology information of a public subnet corresponding to a display request for a first network resource, the public subnet comprising a first subnet and a second subnet, the first subnet being a subnet comprising the first network resource, the second subnet being a subnet other than the first subnet, the topology information comprising information of at least one network resource of the first subnet and the second subnet and a connection relationship between at least one network resource; and distinguishing and displaying the first network resource based on the displayed topology information.

[0007] By displaying the topology information including the information of at least one network resource of the first subnet and the second subnet and the connection relationship between the at least one network resource, the displayed topology information is made more comprehensive, the first network resource is displayed distinctively in the topology information, and the first network resource is displayed with better visualization effect.

[0008] In one possible implementation, a public subnet is a subnet in the network topology that includes the first network resource and has the fewest number of network elements and / or the lowest hierarchy. Determining a public subnet using this method ensures the integrity of the first network resource in the public subnet while avoiding designating overly large subnets as public subnets, which could lead to redundant topological information for the public subnet.

[0009] In one possible implementation, the first network resource includes multiple network elements, any one of the multiple network elements corresponds to a reference subnet, and the reference subnet is a subnet in the network topology that includes any one network element and includes the fewest number of network elements and / or has the lowest level; the public subnet is a subnet in the network topology that includes multiple reference subnets corresponding to multiple network elements and includes the fewest number of network elements and / or has the lowest level. When the first network resource includes multiple network elements, first determining multiple reference subnets and then determining the public subnet that includes the multiple reference subnets can ensure the accuracy of the determined public subnet, further ensure the integrity of the first network resource in the public subnet, and reduce redundancy that may be caused by the topological information of the public subnet.

[0010] In one possible implementation, the at least one network resource of the first subnet and the second subnet includes any one of the following: the first subnet and the second subnet; or individual network elements within the first subnet and the second subnet; or individual network elements within the first subnet and the second subnet. The at least one network resource of the first subnet and the second subnet is different, and accordingly, different content is displayed for the at least one network resource, making the display of the at least one network resource more flexible.

[0011] In one possible implementation, the method further includes: obtaining association information of the public subnet, the association information including information about a second network resource connected to the public subnet and a connection relationship between the second network resource and at least one of the first and second subnets; and displaying the association information of the public subnet based on the displayed topology information. In addition to displaying the topology information of the public subnet, the association information of the public subnet can also be displayed, making the displayed information more comprehensive, avoiding severing the connection between the public subnet and other network resources in the network topology, and improving the integrity of the displayed topology information of the public subnet.

[0012] In one possible implementation, obtaining association information for a public subnet includes: determining, in the third subnet, a second network resource connected to the public subnet based on topological information of the public subnet and subnet parameters of a third subnet connected to the public subnet, wherein the subnet parameters include at least one of subnet coarseness and subnet depth, wherein the subnet coarseness indicates the density of network elements in the third subnet, and the subnet depth indicates the relative size of the third subnet's hierarchy to a reference hierarchy; and determining the association information for the public subnet based on the second network resource. Determining the second network resource in the third subnet connected to the public subnet based on the subnet parameters can ensure that the determined second network resource better meets display requirements.

[0013] In one possible implementation, obtaining topology information of a public subnet corresponding to a display request for a first network resource includes: obtaining an identifier of the first network resource carried in the display request; and determining the topology information of the public subnet based on the identifier of the first network resource and the network topology. Determining the topology information of the public subnet based on the identifier of the first network resource can ensure the accuracy of the determined public subnet, thereby ensuring the accuracy of the topology information of the public subnet.

[0014] In a second aspect, a device for displaying topology information is provided, the device including: an acquisition module for acquiring topology information of a public subnet corresponding to a display request for a first network resource, the public subnet including a first subnet and a second subnet, the first subnet being a subnet including the first network resource, and the second subnet being a subnet other than the first subnet, the topology information including information of at least one network resource of the first subnet and the second subnet and a connection relationship between at least one network resource; a display module for distinguishing and displaying the first network resource based on the displayed topology information.

[0015] In a possible implementation manner, the public subnet is a subnet in the network topology that includes the first network resource and includes the least number of network elements and / or the lowest level.

[0017] In one possible implementation, at least one network resource of the first subnet and the second subnet includes any one of the following: the first subnet and the second subnet; or, each network element within the first subnet and the second subnet; or, each network element within the first subnet and the second subnet.

[0018] In one possible implementation, the acquisition module is further used to obtain association information of the public subnet, where the association information includes information of a second network resource connected to the public subnet and a connection relationship between the second network resource and at least one network resource of the first subnet and the second subnet; the display module is further used to display the association information of the public subnet based on the topology information.

[0019] In one possible implementation, an acquisition module is configured to determine, in a third subnet, a second network resource connected to the public subnet based on topological information of the public subnet and subnet parameters of the third subnet connected to the public subnet, the subnet parameters including at least one of a subnet density and a subnet depth, the subnet density indicating the density of network elements in the third subnet, and the subnet depth indicating the relative size of the hierarchy of the third subnet to a reference hierarchy; and determine association information of the public subnet based on the second network resource.

[0020] In a possible implementation, the display module is configured to obtain an identifier of a first network resource carried in a display request; and determine topology information of the public subnet based on the identifier of the first network resource and the network topology.

[0040] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0041] With the continuous development of information and communications technology (ICT) networks, the scale of networks has gradually expanded, the number of network elements (NEs) in the network has gradually increased, and the connection relationships between various network elements have become more and more complex. Among them, network element is a general term for various types of equipment in the network. A device in the network can be a network element. For example, a server, a base station, or a computer room can be a network element. Two network elements are connected to form a link, and the two endpoints of the link are two network elements. Multiple adjacent links are connected end to end to form a path. Multiple interconnected network elements can form a subnet. A subnet can include one or more network elements, and can also include one or more subnets.

[0042] For example, referring to Figure 1, a schematic diagram of the structure of a subnet is shown. The layer 1 subnet is the highest-level subnet in Figure 1. The layer 1 subnet includes layer 2 subnet A, layer 2 subnet B, and layer 2 subnet C. In other words, layer 2 subnet A, layer 2 subnet B, and layer 2 subnet C belong to the layer 1 subnet. Correspondingly, the layer 2 subnet includes layer 3 subnets. For example, layer 2 subnet A in Figure 1 includes layer 3 subnet A, layer 3 subnet B, and layer 3 subnet C. The circles in Figure 1 represent network elements, such as network element 21, network element 22, and network element 1, and the line between any two network elements represents that the two network elements can achieve communication connection through wired or wireless communication.

[0043] Any two network elements connected together form a link. The two network elements on a link can be both network elements belonging to a subnet at any layer. For example, the two network elements represented by the black circles in Layer 3 subnet A in Figure 1 belong to both Layer 3 subnet A. These two network elements can serve as the two endpoints of a link, connected to form a link. The network element represented by the black circle in Layer 3 subnet C and the network element 4 represented by the black circle in Layer 3 subnet D both belong to Layer 1 subnet 11. These two network elements can also serve as the two endpoints of a link, connected to form a link.

[0044] As shown in Figure 1, the excessive number of network elements (NEs) and the complex connections between them necessitate organizing the network topology using a multi-level, multi-subnet approach similar to that shown in Figure 1 to clearly display the network structure. This constructs a three-dimensional, multi-branch tree structure. For production and maintenance personnel, tasks such as path calculation, fault location, service performance measurement, and resource search require searching for required network resources within the large network topology and accurately obtaining network resource information within the displayed local topology view.

[0045] An embodiment of the present application provides a method for displaying topology information, which can accurately focus on network resources and display the topology information corresponding to the network resources. Referring to Figure 2, a schematic diagram of an implementation scenario of this method is shown. The implementation scenario includes an input device, a network management device, and a display device. The input device, the network management device, and the display device can be integrated into different devices, or integrated into the same device, or any two of the input device, the network management device, and the display device can be integrated into the same device, and the other device can be integrated into another device. Regardless of the integration status of the input device, the network management device, and the display device, communication between the devices can be achieved through wired or wireless connections.

[0046] A network management system is installed on a network management device, which includes a display request receiving interface, a conversion module, and a topology view sending interface. The display request receiving interface is capable of receiving display requests sent by an input device, thereby allowing the network management device to obtain a user's request to display network resources. The network management device can then determine the topology information corresponding to the network resources to be displayed in the network topology based on the display request. For example, the conversion module in the network management device determines the topology view corresponding to the display request based on the display request, and sends the topology view to the display device via the topology view sending interface. The topology view is a view that includes the topology information to be displayed, and the display device can display the received topology view to achieve the display of the topology information.

[0047] The embodiment of the present application provides a method for displaying topology information, which can be applied to the implementation scenario shown in Figure 2. Referring to Figure 3, a schematic flow chart of a method for displaying topology information is shown, which includes but is not limited to the following S301 to S302.

[0048] S301, obtain topology information of a public subnet corresponding to a display request for a first network resource, where the public subnet includes a first subnet and a second subnet, where the first subnet is a subnet including the first network resource, and the second subnet is a subnet other than the first subnet, and the topology information includes information of at least one network resource of the first subnet and the second subnet, and a connection relationship between at least one network resource.

[0049] In one possible implementation, obtaining topology information of a public subnet corresponding to a display request for a first network resource includes: obtaining an identifier of the first network resource carried in the display request; and determining topology information of the public subnet based on the identifier of the first network resource and the network topology.

[0050] Exemplarily, the input device shown in FIG2 can determine the network resources that need to be displayed in focus according to the needs of the user, that is, determine the first network resource, thereby determining the identifier of the first network resource to generate a display request. The embodiment of the present application does not limit the method of fixed-focus display. For example, the fixed-focus display can be to highlight the network resources that need to be displayed at the center of the display interface or topology view. The highlighting can be a highlight display, an enlarged display, or a stereoscopic display through a 3D projection, etc. The network resources required by the user are displayed in focus, so that the display effect of the network resources is more intuitive, and the efficiency of the user in obtaining the information of the displayed network resources through the display interface or topology view is improved. In addition, the embodiment of the present application does not limit the number and type of network resources. Network resources can include one or more network elements, subnets, links and paths.

[0051] The following describes the process of determining the identifier of the first network resource. Optionally, if the first network resource is one or more network resources, the identifier of the first network resource can be determined based on the correspondence between the network resource and the resource identifier. The correspondence between the network resource and the resource identifier can be manually statically configured at the input device, or can be dynamically learned by the input device based on the network. For example, if the user's requirement is to display network element 63 in a fixed focus manner, that is, the first network resource is network element 63, the identifier of network element 63 can be determined based on the network resource and the resource identifier.

[0052] An application with a search function can also be deployed in the input device. If the user's demand is to focus on displaying one or more uncertain network resources, the application can perform a fuzzy search based on the user's demand to determine the search results of the fuzzy search. The search results may include one or more network resources, and the search results are the first network resources. The identifier of the first network resource can then be determined based on the correspondence between the network resources and the identifiers of the resources. For example, if the input device obtains that the user's demand is to focus on displaying the network elements in area A, the input device can determine the various network elements in area A in the ICT network, determine the various network elements in area A as the first network resource, and determine the identifier of the first network resource based on the correspondence between the stored network resources and the identifiers of the resources.

[0053] Exemplarily, the identifier of a resource may be a number, a physical address, or an Internet Protocol (IP) address that can identify a network resource in an ICT network. The embodiment of the present application does not limit the type and form of the identifier of the resource. The identifier of a resource can be divided into a single resource identifier for a single network resource and a group resource identifier for multiple network resources. For example, an identifier that can identify a single network element, a single subnet, a single link, or a single path is a single resource identifier. Multiple network resources can be used as a group of network resources, and the multiple network resources included in a group of network resources can be network resources of the same type or network resources of different types. For example, a group of network resources can include multiple network elements, or can include both multiple network elements and multiple links, multiple paths, or multiple subnets. A group of network resources corresponds to a group resource identifier, and a group resource identifier corresponding to a group of network resources can be the sum of the identifiers of each network resource in a group of network resources, or can be a separate identifier that can identify this group of network resources.

[0054] For example, the single resource identifier of a single network element 63 may be the number 1863 of network element 63, or the physical address of network element 63, location xx in District C, City B, Province A, or the IP address xxx.xxx.xx.63 of network element 63. Network resource 3 is a group of network resources, including network element 31 and link 32. The group resource identifier corresponding to network resource 3 may include the identifiers of network element 31 and link 32, or may be an independent identifier that can identify this group of network resources.

[0055] After determining the identifier of the first network resource, the identifier of the first network resource can be used as a request parameter to generate a display request for requesting a focused display of the first network resource, i.e., a display request for the first network resource. The input device sends the generated display request to the network management device via the display request receiving interface. The display request can be sent to the network management device by the user controlling the input device, or by the application performing the search controlling the input device after the search.

[0056] After receiving the display request carrying the identifier of the first network resource, the network management device can determine the public subnet to which the first network resource belongs in the network topology. Optionally, the public subnet can be the subnet in the network topology that includes the first network resource and has the least number of network elements and / or the lowest level.

[0057] Among them, the hierarchy of the subnet can be divided manually or automatically generated according to the content of the network topology, and the embodiments of the present application do not limit this. For example, the network elements in the network topology can be divided into subnets of different levels according to the geographical location or the importance of the network element. In one possible implementation, the first-level subnet can correspond to the national backbone network, the second-level subnet can correspond to the provincial backbone network, the third-level subnet can correspond to the municipal network, and the fourth-level subnet can correspond to the regional network. For example, referring to Figure 4, a schematic diagram of the topological structure of a multi-level and multi-subnet physical network model is shown. The subnet 11 composed of network resources represented by the diamond is a first-level subnet, and the subnet composed of network resources represented by the pentagon is a second-level subnet, such as subnet 21. The subnet composed of network resources represented by the triangle is a third-level subnet, such as subnet 31. The subnet composed of network resources represented by the circle is a fourth-level subnet, such as the single-network element subnet composed of network element 41. Higher-level subnets correspond to or contain lower-level subnets. For example, subnet 11 is the highest-level subnet shown in Figure 4 and contains subnet 21 and other Layer 2 subnets. Subnet 21 contains subnet 31, shown in the upper left corner of Figure 4, and three Layer 3 subnets connected to subnet 31. Subnet 31 contains a single Layer 4 subnet, consisting of network element 41, shown in the upper left corner of Figure 4, and three Layer 4 subnets connected to network element 41.

[0058] If the first network resource is a network element, the public subnet can be a subnet of a single network element in the network topology, which includes both the network element itself and the smallest subnet that includes at least one other subnet. For example, referring to Figure 1 , the first network resource includes network element 1, represented by a black circle, in Layer-3 subnet A. As shown in Figure 1 , network element 1 belongs to both Layer-3 subnet A and Layer-2 subnet A. Since Layer-3 subnet A includes network element 1 and has the lowest level and the fewest number of network elements among the subnets that include network element 1, the public subnet corresponding to network element 1 can be Layer-3 subnet A.

[0059] When the first network resource is a network element, the first subnet included in the public subnet corresponding to the first network resource can be a subnet of a single network element constituted by the first network resource itself, and the second subnet included in the public subnet can be a subnet in the public subnet except the first network resource.

[0060] In one possible implementation, the first network resource includes multiple network elements, any one of the multiple network elements corresponds to a reference subnet, and the reference subnet is a subnet in the network topology that includes any one network element and includes the least number of network elements and / or the lowest level. The public subnet can be a subnet in the network topology that includes multiple reference subnets corresponding to multiple network elements and includes the least number of network elements and / or the lowest level.

[0061] If the reference subnets corresponding to multiple network elements included in the first network resource are the same subnet, the reference subnet can be determined as the common subnet corresponding to the first network resource. For example, referring to Figure 1 , the first network resource includes network elements 1 and 2, represented by black circles in Layer 3 subnet A. If the reference subnets corresponding to both network elements 1 and 2 are Layer 3 subnet A, Layer 3 subnet A can be determined as the common subnet of the first network resource.

[0062] If the reference subnets corresponding to the multiple network elements included in the first network resource are different subnets, the smallest subnet that includes each reference subnet can be determined as the public subnet corresponding to the first network resource. For example, referring to Figure 1 again, taking the example of a first network resource including two network elements, the two network elements are network element 1 represented by the black circle in layer-3 subnet A and network element 3 represented by the black circle in layer-3 subnet C. The reference subnet corresponding to network element 1 can be layer-3 subnet A, and the reference subnet corresponding to network element 3 can be layer-3 subnet C. If both layer-2 subnet A and layer-1 subnet are subnets that include layer-3 subnet A and layer-3 subnet C, layer-2 subnet A, which includes the fewest network elements and has the lowest level, can be determined as the public subnet corresponding to the first network resource.

[0063] For another example, referring again to Figure 1 , assuming that the first network resource includes three network elements, the three network elements are network element 1 represented by a black circle in layer-3 subnet A, network element 3 represented by a black circle in layer-3 subnet C, and network element 4 represented by a black circle in layer-3 subnet D. The reference subnet corresponding to network element 1 can be layer-3 subnet A, the reference subnet corresponding to network element 3 can be layer-3 subnet C, and the reference subnet corresponding to network element 4 can be layer-3 subnet D. In Figure 1 , only layer-1 subnets are included in layer-3 subnets A, C, and D. In this case, layer-1 subnets can be determined as the public subnet corresponding to the first network resource.

[0064] In the case where the first network resource includes multiple network elements, the first subnet included in the public subnet corresponding to the first network resource can be a subnet of a single network element constituted by the first network resource itself or a reference subnet corresponding to each network element in the first network resource, and the second subnet included in the public subnet can be a subnet of a single network element or a subnet of multiple network elements constituted by other network elements in the public subnet except the first subnet.

[0065] After determining the public subnet corresponding to the first network resource, topology information of the public subnet can be determined in the network topology. The topology information of the public subnet can include information about at least one network resource of the first subnet and the second subnet, as well as the connection relationship between the at least one network resource. The embodiments of the present application do not limit the network resource information. For example, the network resource information can include at least one of the network resource number, the physical location of the network resource, the network resource's operating status, and the network resource's attributes. The network resource's operating status can include a state such as engineering or engineering debugging. If a network resource's operating status is engineering, it means that the network resource is already being used in a project. If a network resource's operating status is engineering debugging, it means that the network resource is still in the debugging phase and is not being used in the project. The attributes of the network resource can be, for example, an intelligent optical transport network (OTN) or a router. The connection relationship between two network resources can be represented by a line. The embodiments of the present application do not limit the shape and type of the line. For example, the shape of the line can be a line segment, an arc, or a broken line, and the type of the line can be a single line, a double line, a solid line, or a dashed line.

[0066] S302: Based on the displayed topology information, differentiate and display the first network resources.

[0067] After the network management device completes the acquisition of the topology information of the public subnet according to the display request, it can convert the topology information of the public subnet into a topology view, and send the topology view to the display device through the topology view sending interface. The display device displays the topology view to realize the display of the topology information of the public subnet.

[0068] In the embodiment of the present application, the method of displaying topology information can be divided into different situations according to the difference in at least one network resource between the first subnet and the second subnet, including but not limited to the following situations A1 to A3.

[0069] In case A1, the at least one network resource of the first subnet and the second subnet includes the first subnet and the second subnet.

[0070] In a possible implementation, information of the first subnet and the second subnet, as well as the connection relationship between the first subnet and the second subnet, can be displayed. The first subnet can be a subnet consisting of a single network element or a subnet including multiple network elements.

[0071] For example, see Figure 5, which shows a schematic diagram of a topology information display result. The black circle represents the first subnet, and the solid white circle connected to the black circle represents the second subnet. The display result not only shows the first and second subnets, but also shows the connection relationship between the first and second subnets, represented by a solid line segment. Furthermore, the display result also includes information about the first and second subnets, which is not shown in Figure 5.

[0072] In case A2, at least one network resource of the first subnet and the second subnet includes each network element in the first subnet and the second subnet.

[0073] In a possible implementation, since the first subnet is the subnet where the first network resource is located, and the second subnet does not include the queried first network resource, the first subnet may be displayed in an expanded manner and the second subnet may be displayed roughly.

[0074] For example, see Figure 6, which shows a schematic diagram of another display result of topology information. The right side of Figure 6 shows the composition of a public subnet, including subnets 1 to 8. The first network resource is the path shown on the left side of Figure 6, including network element 64 - network element 63 - network element 53 - network element 1 - network element 3 - network element 4 - network element 2 - network element 73 - network element 72. Subnets 1 to 7, which include the first network resources, are displayed in an expanded manner, that is, each network element within the first subnet and the connection relationships between each network element are displayed. Among them, subnets 5, 6, and 7 are multi-network element subnets, each including five different network elements, while subnets 1, 2, 3, and 4 are subnets composed of a single network element. The second subnet, subnet 8, which does not include the first network resources, is roughly displayed, that is, only subnet 8 is displayed, without the information of each network element included in subnet 8 and the connection relationships between each network element in subnet 8 (represented by dashed lines). In addition, the display result also includes information of each network element of the first subnet and information of the second subnet, which are not shown in FIG. 6 .

[0075] In case A3, at least one network resource of the first subnet and the second subnet includes each network element in the first subnet and each network element in the second subnet.

[0076] In this case, both the first subnet and the second subnet are expanded and displayed, that is, the network elements included in the first subnet and the second subnet, as well as the connection relationship between the network elements included in the first subnet and the connection relationship between the network elements included in the second subnet are displayed.

[0077] For example, referring to Figure 6 again, if the first network resource is a link consisting of network element 53 and network element 63, then the first subnet is subnet 5 and subnet 6, and subnet 1, subnet 2, subnet 3, subnet 4, subnet 7, and subnet 8 are all second subnets. Figure 6 expands not only subnet 5 and subnet 6, but also subnet 1, subnet 2, subnet 3, subnet 4, subnet 7, and subnet 8.

[0078] Regardless of which situation the content included in at least one network resource of the first subnet and the second subnet corresponds to, the first network resource can be automatically distinguished and displayed based on the displayed topology information. For example, the first network resource is displayed in focus, and the other network resources in the topology information of the public subnet are displayed in a non-focused manner, so that the other network resources in the topology information of the public subnet are easily distinguished from the first network resource. Exemplarily, the information of the first network resource and the connection relationship between the first network resources can be highlighted, and the other network resources in the topology information of the public subnet can be displayed in a non-highlighted manner, so that the display brightness of the other network resources in the topology information of the public subnet is lower than the display brightness of the first network resource. Alternatively, the information of the first network resource and the connection relationship between the first network resources can be magnified and displayed, so that the display size of the other network resources in the topology information of the public subnet is relatively smaller than the display size of the first network resource. Alternatively, different colors can be used to represent the first network resource and the other network resources in the topology information of the public subnet.

[0079] For example, referring to Figure 5, the first network resource is the network resource represented by the black circle in area I in Figure 5, and the network resources represented by the white circles connected by black solid lines in areas B, C, F, G, J, K and L are the network resources other than the first network resource in at least one network resource of the first subnet and the second subnet.

[0080] FIG7 is a schematic diagram illustrating another display result of topology information. The first network resource includes two network elements. For example, the first network resource is a link formed by the network element represented by the black circle in area B and the network element represented by the black circle in area I in FIG7 . The network resource represented by the white circle connected to the link is a network resource other than the first network resource in at least one of the first and second subnets.

[0081] FIG8 is a schematic diagram illustrating another display result of topology information. The first network resource includes six network elements. For example, the first network resource is a path formed by connecting the network elements represented by black circles in areas A, B, I, J, and F, and the network element represented by a black circle in area L. The network resources represented by white circles connecting the path and the network element are network resources other than the first network resource in at least one of the first and second subnets.

[0082] Optionally, if the first network resource includes a path, the embodiment of the present application can automatically focus and display the previous hop of the path when displaying the path. For example, the network element represented by the cross circle in Figure 8 is the previous hop of the path in Figure 8.

[0083] In addition, the user can also click on the first network resource in the topology view displayed on the display device to realize differentiated display of the first network resource.

[0084] In one possible implementation, in an embodiment of the present application, the display status of the first subnet and the second subnet can be adjusted according to user needs, that is, the expansion degree of the first subnet and the second subnet can be adjusted according to user needs. The user needs can be sent to the network management device through an input device. For example, the user can click on the roughly displayed first subnet in the topology view that displays the topology information, and click on the button to expand the subnet to input the user needs. After obtaining the user demand to expand the display of the first subnet, the first subnet can be expanded and displayed, and the display of the information of the first subnet is converted to the display of the information of each network element included in the first subnet and the connection relationship between the network elements included in the first subnet.

[0085] For another example, in a topology view displaying topology information, a user can click to expand the second subnet, and then click to collapse the subnet to input user requirements. After obtaining the user's requirement to roughly display the second subnet, the second subnet can be roughly displayed, switching from displaying information about each network element included in the second subnet and the connection relationships between the network elements included in the second subnet to displaying information about the second subnet.

[0086] Alternatively, the user requirement may also be a zoom ratio, and the embodiments of the present application can implement automatic zooming of the topology information based on the zoom ratio. Optionally, the user can adjust the zoom ratio of the topology view by sliding the mouse wheel. The zoom ratio can be determined based on the distance and direction of the wheel sliding. For example, sliding the wheel upward can represent a zoom ratio increase, and sliding the wheel downward can represent a zoom ratio decrease. The greater the distance the wheel slides, the greater the degree of adjustment to the zoom ratio, and the smaller the distance the wheel slides, the smaller the degree of adjustment to the zoom ratio.

[0087] If the user requires a smaller zoom ratio, the already expanded first or second subnet can be roughly displayed, switching from displaying information about each network element of the first subnet and the connection relationships between the network elements of the first subnet to displaying information about the first subnet. Alternatively, switching from displaying information about each network element of the second subnet and the connection relationships between the network elements of the second subnet to displaying information about the second subnet. Alternatively, switching from displaying information about each network element of the first and second subnets and the connection relationships between the network elements of the first and second subnets to displaying information about the first and second subnets and the connection relationships between the first and second subnets.

[0088] If the user requires a larger zoom ratio, the roughly displayed first subnet or second subnet can be expanded and displayed, switching from displaying the information of the first subnet to displaying the information of each network element of the first subnet and the connection relationship between the network elements of the first subnet.

[0089] Optionally, when automatically zooming, subnets can be expanded or collapsed hierarchically to achieve automatic multi-level zoom display, which can include: calculating the reference subnet hierarchy of the first subnet and the first network resource, determining the hierarchical path from the first subnet to the reference subnet of the first network resource, and opening the subnets on the hierarchical path layer by layer and in situ. For example, referring to Figure 1, if the first subnet is a 2-layer subnet, the first subnet includes 3-layer subnet A and 3-layer subnet B, and 3-layer subnet A can also include 4-layer subnet A and 4-layer subnet B not shown in Figure 1, and 4-layer subnet A is the reference subnet of the first network resource, then when the first subnet is roughly displayed, after receiving the user's request to increase the zoom ratio for the first time, the first subnet can be expanded and displayed to display the information of 3-layer subnet A and 3-layer subnet B within the first subnet, as well as the connection relationship between 3-layer subnet A and 3-layer subnet B. Then, if a user request to enlarge the zoom ratio is received for the second time, the 3-layer subnet A can be expanded to display the information of the 4-layer subnet A and the 4-layer subnet B, as well as the connection relationship between the 4-layer subnet A and the 4-layer subnet B, to achieve multi-level zoom display of the first subnet.

[0090] As shown in Figure 6, the minimum common subnet of the link formed by NE 53 and NE 63 is the subnet to which subnet 6 and subnet 5 belong, that is, the subnet consisting of subnets 1 to 8. When displaying this link, the link connecting subnet 6 and subnet 5 can be displayed. The automatic scaling function can also be used to achieve automatic multi-level scaling, automatically expanding the reference subnets to which the NEs at both ends of the link belong, that is, automatically expanding subnet 5 and subnet 6, and displaying the link as the precise connection between NE 63 and NE 53, allowing the complete end-to-end (E2E) path of the link to be viewed in the zoomed topology.

[0091] In one possible implementation, the embodiment of the present application can also obtain association information of the public subnet, the association information including information of the second network resource connected to the public subnet and the connection relationship between the second network resource and at least one network resource of the first subnet and the second subnet; on the basis of displaying the topology information, the association information of the public subnet is displayed.

[0092] For example, referring to Figure 5 , each network element connected by solid lines in Figure 5 represents at least one network resource included in the public subnet. The dashed circles in Areas A, D, E, and L connected to at least one network resource in the public subnet by dashed lines represent second network resources. The dashed lines in the figure represent the connection between the second network resource and the at least one network resource. Furthermore, the displayed result also includes information about the second network resource, not shown in Figure 5 .

[0093] Optionally, obtaining the association information of the public subnet may include determining a second network resource connected to the public subnet in the third subnet based on the topological information of the public subnet and subnet parameters of a third subnet connected to the public subnet, the subnet parameters including at least one of subnet density and subnet depth, the subnet density indicating the density of network elements in the third subnet, and the subnet depth indicating the relative size of the hierarchy of the third subnet and the reference hierarchy; determining the association information of the public subnet based on the second network resource.

[0094] In one possible implementation, the subnet density may be the ratio of the number of network elements included in the third subnet to the range of the third subnet, and the subnet depth may be the difference between the level of the third subnet and the level of the reference subnet. The reference level may be a statically set level or may be dynamically adjusted according to display requirements.

[0095] For example, the topology information of the public subnet can be determined as the center of the area to be displayed, and the range of the area to be displayed can be calculated based on the range of the center area. Furthermore, based on the third subnet included in the topology tree in the network topology, the zoom scale, and the subnet parameters of the third subnet, the range of the area to be displayed and the second network resources within the zoom level can be determined. The area to be displayed is the user's visible area.

[0096] The embodiments of the present application do not limit the calculation method and representation method of the range of the area to be displayed. For example, a range of N times the range of the public subnet can be determined as the area to be displayed, N can be greater than or equal to 1, and the range of the area to be displayed can be represented by coordinates. For example, if the area to be displayed is a rectangle, the two diagonals of the area to be displayed can be represented by two-dimensional coordinates (x0y0, x1y1), thereby representing the range of the area to be displayed.

[0097] For example, see Figure 9, which shows a schematic diagram of an area to be displayed. The solid rectangle represents the area to be displayed, calculated in the network topology. The dashed-line area represents the public subnet. Subnets 10, 12, 13, and 15 are the third subnets in the area to be displayed that are connected to the public subnet. Subnets 9, 11, 14, and 16 are subnets in the network topology that are not included in the area to be displayed.

[0098] After determining the area to be displayed, the third subnet connected to the public subnet within the area to be displayed at the current zoom level can be determined based on the zoom scale. Furthermore, the second network resource can be determined based on at least one of the subnet density and subnet depth of the third subnet. Taking the determination of the second network resource based on the subnet density of the third subnet as an example, if the determined subnet density of the third subnet is greater than the density threshold, that is, the number of network elements included in the third subnet is small but the range corresponding to the third subnet is large, then the display mode of the third subnet can be determined as coarse display, that is, the third subnet is determined as the second network resource. Alternatively, if the subnet density of the third subnet is less than or equal to the density threshold, that is, the number of network elements included in the third subnet is large but the range corresponding to the third subnet is small, then the display mode of the third subnet can be determined as expanded display, that is, each or part of the network elements included in the third subnet is determined as the second network resource.

[0099] Accordingly, taking the example of determining the second network resource based on the subnet depth of the third subnet, if the reference level is the level of the public subnet, the depth of the third subnet is large, that is, the difference between the level of the third subnet and the level of the public subnet is large, which means that the correlation between the various network resources included in the third subnet and at least one network resource in the public subnet is small, then the display mode of the third subnet can be determined as a rough display, that is, the third subnet is determined as the second network resource. If the depth of the third subnet is small, that is, the difference between the level of the third subnet and the level of the public subnet is small, which means that the correlation between the various network resources included in the third subnet and at least one network resource in the public subnet is large, then the display mode of the third subnet can be determined as an expanded display, that is, the various network elements or some network elements included in the third subnet are determined as the second network resource.

[0100] In one possible implementation, the reference level is the lowest level in the network topology. A greater depth of the third subnet indicates a larger range of the third subnet, making it less likely that the third subnet will be expanded and displayed. A smaller depth of the third subnet indicates a smaller range of the third subnet, making it more likely that the third subnet will be expanded and displayed. Furthermore, the second network resource can be determined by combining the subnet density and subnet depth of the third subnet.

[0101] Related technologies only support searching for individual network resources and fail to support searching for a group of network resources, such as complete forwarding paths or fuzzy searches. After searching for a network resource, the network resource is determined to be located within a specific subnet, and the subnet topology of that subnet is displayed to locate the network resource. For example, when searching for multiple network elements distributed across multiple subnets, related technologies typically use the lowest-level subnet to which each network element in the path belongs to view the local forwarding path within each subnet. For example, in Figure 6, the two endpoints of link C are network element 63 and network element 53, respectively. When displaying link C, related technologies will separately display subnet 6 to which network element 63 belongs and subnet 5 to which network element 53 belongs, without displaying the connection between subnet 6 and subnet 5. This network resource display method in related technologies separates the network relationship or connection between the subnet to which the network resource belongs and other subnets, limiting the usability of the network management and control system and resulting in poor visualization of network resources.

[0102] The embodiment of the present application makes the displayed topology information more comprehensive by displaying information of at least one network resource including the first subnet and the second subnet and topology information of the connection relationship between at least one network resource, and distinguishes the first network resource in the topology information to display the first network resource with better visualization effect.

[0103] In summary, the embodiment of the present application can display the first network resource of the multi-level subnet in a multi-level and multi-subnet network topology in an automatic focusing manner, and the automatic focusing of the first network resource enables the topology information of the public subnet corresponding to the first network resource to be adaptively presented. The display area of ​​the public subnet in the network topology can be determined based on the position of the public subnet in the network topology and the comprehensive calculation of the subnet parameters, and the topology information of the displayed network resources can be presented according to the zoom ratio and the area to be displayed. In addition, the method provided by the embodiment of the present application not only supports the search of a single network resource, but also supports the search of multiple network resources and fuzzy search, thereby improving the reliability of the search results.

[0104] The above describes the method for displaying topology information provided by an embodiment of the present application. Corresponding to the above method, an embodiment of the present application also provides a device for displaying topology information.

As shown in FIG. 10 , the device for displaying topology information provided by an embodiment of the present application includes the following modules.

[0110] In one possible implementation, an acquisition module 1001 is used to determine, in the third subnet, a second network resource connected to the public subnet based on the topology information of the public subnet and subnet parameters of the third subnet connected to the public subnet, where the subnet parameters include at least one of a subnet density and a subnet depth, the subnet density indicating the density of network elements in the third subnet, and the subnet depth indicating the relative size of the hierarchy of the third subnet and the reference hierarchy; and determine association information of the public subnet based on the second network resource.
