1. Technical Field
The invention relates generally to displaying a topology. In particular, the invention provides a solution that enables a user to selectively alter the emphasis of one or more topologic items in the topology.
2. Background Art
One solution for viewing the status of a network or the like is the use of a topology view. Within the topology view, network resources (e.g., printer, router, computer, etc.), their relationships, and their current states (e.g., normal, critical, maintenance, etc.) can be displayed. Network management software such as Tivoli™ offered by International Business Machines Corp. of Armonk, N.Y., can be used to generate such a topology view.
The topology view provides several advantages over alternative views such as a table or the like for network resources. For example, a user can use the topology view of a network to determine important resources with critical failures (e.g., “what to work”). In particular, the relationship between various network resources, aggregated with status information, can be used to determine which resource failures most severely impact the performance of the overall network.
However, as the number of resources and resource states increases for a particular network, the topology view becomes unwieldy for a user. For example, a topology view generated using Tivoli™ can include hundreds of resources and their corresponding relationships for a particular network. Additionally, Tivoli™ specifies sixteen levels/values of resource states that can be indicated by displaying a decorator for each resource. As a result, it is often difficult for a user of a topology view to glance at large sets of resources to determine “what to work.” In this case, a user will frequently switch to use the table view or the like, which allows for better sorting and filtering capabilities. Consequently, much of the relationship information and potential benefit of using the topology view is lost.
To help alleviate some of these problems, the topology view is often customized based on an understood business or information technology practice tailored for the user's environment. In this case, the user can select to apply a pre-defined filter for displaying the topology view. However, this solution does not allow the user to dynamically tailor the topology view.
Similar problems exist in other types of topology views. For example, electronic maps are commonly used to portray directional information to a user. In particular, an efficient route from one location to another can be highlighted on a map. However, the map may include numerous details, such as secondary roads, landmarks, geographic area information, etc., that may be desired by some users, but are merely clutter for other users. As the map becomes more detailed e.g., due to a densely populated area that includes numerous secondary roads, landmarks, etc., the directional information becomes more difficult to ascertain.
As a result, a need exits for a solution that enables a user to dynamically tailor a topology view. In particular, a need exists for a method, system, program product, and user interface that allow a user to dynamically alter a baseline that is used to adjust the display of one or more topologic items in the topology view. In this manner, additional information can be dynamically emphasized or de-emphasized based on the current requirements of the user.
The invention provides an improved solution for displaying a topology. Specifically, under the present invention, a user can selectively alter a baseline that is applied to one or more topologic items for the topology. In particular, the baseline is used to adjust an emphasis for each of the corresponding topologic items. As a result, the user can dynamically adjust the emphasis of one or more topologic items while viewing the topology.

The illustrative aspects of the present invention are designed to solve the problems herein described and other problems not discussed, which are discoverable by a skilled artisan.
These and other features of this invention will be more readily understood from the following detailed description of the various aspects of the invention taken in conjunction with the accompanying drawings that depict various embodiments of the invention, in which:
It is noted that the drawings of the invention are not to scale. The drawings are intended to depict only typical aspects of the invention, and therefore should not be considered as limiting the scope of the invention. In the drawings, like numbering represents like elements between the drawings.
As indicated above, the invention provides an improved solution for displaying a topology. Specifically, under the present invention, a user can selectively alter a baseline that is applied to one or more topologic items for the topology.

Turning to the drawings,
In any event, topology 16 can include additional network attributes regarding the connector(s), nodes, and/or the environment of the connector(s) and nodes. To this extent, topology 16 can include one or more information items. An information item can be associated with a connector and/or node, or it can be included in topology 16 apart from any connector or node. For example, when topology 16 comprises a network topology, topology 16 can include information items that describe a status and/or an importance of one or more communication connections and/or network resources. When topology 16 comprises a map, topology 16 can include information items such as points of interest, bodies of water, county/state boundaries, etc. Further, topology 16 can include information items for roads such as a type, distance, construction status, etc., and information items for towns such as size, capital, etc.
As noted previously, topology system 30 displays topology 16 to user 12. In one embodiment, topology system 30 is implemented on computer 14 as computer program code. For example, computer 14 can comprise any type of personal computer that is accessed and operated by user 12. To this extent, computer 14 is shown including a processor 20, a memory 22, an input/output (I/O) interface 24, and a bus 26. Further, computer 14 is shown in communication with an external I/O device/resource 28 and a storage system 29.
In general, processor 20 executes computer program code such as topology system 30, that is stored in memory 22 and/or storage system 29. While executing computer program code (e.g., topology system 30), processor 20 can read and/or write data (e.g., topology 16) to/from memory 22, storage system 29, and/or I/O interface 24. Bus 26 provides a communication link between each of the components in computer 14. User 14 interacts with computer 14 using one or more I/O devices 28 (e.g., keyboard, pointing device, display, etc.). It is understood, however, that if computer 14 comprises a handheld device or the like, one or more I/O devices 28 (e.g., a display) and/or storage system 29 could be contained within computer 14, not externally as shown.
Computer 14 is only illustrative of various possible combinations of hardware. For example, processor 20 may comprise a single processing unit, or be distributed across one or more processing units in one or more locations, e.g., on a client and server. Similarly, memory 22 and/or storage system 29 can comprise any combination of various types of data storage and/or transmission media that reside at one or more physical locations. I/O interface 24 can comprise any system for exchanging information with one or more I/O devices 28 that provide an interface with one or more other computing devices and/or users 12.
Further, user 12 could operate another computing device (not shown) that communicates with computer 14 over a network (also not shown) using I/O device 28 (e.g., network adapter, I/O port, modem, etc.). In this case, the network can comprise any type of communications link. For example, the network can comprise an addressable connection in a client-server (or server-server) environment that may utilize any combination of wireline and/or wireless transmission methods. Further, the network can comprise any combination of various types of networks, including the Internet, a wide area network (WAN), a local area network (LAN), a virtual private network (VPN), etc. Regardless, connectivity and communications between the various computing devices can be implemented using any known protocol(s).
In any event, topology system 30 can display topologic items for topology 16. Each topologic item comprises a visual representation for a connector, node, and/or information item that is included in topology 16. To this extent, topology system 30 is shown including a display system 32 that displays one or more topologic items for topology 16, a criteria system 34 that obtains a set of emphasis criteria for topology 16, an emphasis system 36 that determines an emphasis for one or more topologic items, a baseline system 38 that receives a baseline selected by user 12, and an adjustment system 40 that generates an adjusted emphasis based on the baseline. Operation of each of these systems is described further below. However, it is understood that some of the various systems shown in
Additional aspects of the invention are now discussed with reference to
In order to generate the content of display area 52, criteria system 34 can further obtain a set of emphasis criteria. The set of emphasis criteria can enable display system 32 to alter the appearance of one or more topologic items 54A-D in display area 52. For the illustrative network topology shown in
In one embodiment, the set of emphasis criteria is stored in and obtained from topology 16. In this case, the set of emphasis criteria and/or resource properties can be dynamically updated by a network administrator, network monitoring software and the like to reflect the current properties, status and/or importance of the various network resources. However, the set of emphasis criteria can also be obtained based on user 12. For example, user 12 could comprise a network administrator that wants to focus on a particular subset of the entire network shown in display area 52. In this case, the set of emphasis criteria could assign the highest importance to the various topologic items 54A-D that correspond to the particular subset. Alternatively, user 12 could comprise a technical support individual that interfaces with the end users of the network. In this case, network resources such as personal computers and printers could be assigned the highest importance by the set of emphasis criteria. In any event, it is understood that criteria system 34 could obtain some or all of the set of emphasis criteria automatically (e.g., from topology 16) and/or via a user interface or the like that enable each user 12 to selectively alter the set of emphasis criteria for his/her use.
As noted previously, criteria system 34 can provide the set of emphasis criteria to emphasis system 36 for use in generating the content of display area 52. In particular, emphasis system 36 can apply the set of emphasis criteria to each topologic item 54A-D for topology 16 in order to generate the content of display area 52. In one embodiment, emphasis system 36 can determine a status for various topologic items 54A-C based on the set of emphasis criteria, and emphasis system 36 can add additional topologic items (e.g., topologic item 54D) to be displayed by display system 32 in display area 52. Similarly, an importance for various topologic items 54A-D can be determined based on the set of emphasis criteria. As discussed above, the importance can be based on the importance of the corresponding network resource and/or the importance of the particular network resource to users 12. In this case, display system 32 can alter the display of similar topologic items, such as topologic items 54B-C, based on the relative importance of the corresponding connections.
In any event, emphasis system 36 can determine a default emphasis for each topologic item 54A-D based on the set of emphasis criteria. In one embodiment, the default emphasis can be represented as a value between zero and one hundred percent opacity. In this case, an opacity can be assigned to each type of network resource, the status of the network resource, and/or the importance of the resource. For example, a printer resource may have a relatively low importance and be assigned an opacity often percent, while a router resource may have a relatively high importance and be assigned an opacity of forty percent. Further, a normal status may be assigned an opacity of zero percent, a warning status an opacity of twenty percent, and a critical status an opacity of forty percent. To determine the default emphasis, the opacities assigned to the importance and status for each resource can be summed. In this case, a printer having a normal status would be assigned an opacity of ten percent (ten percent for importance plus zero percent for normal status), while a router having a warning status would be assigned an opacity of sixty percent (forty percent for importance plus twenty percent for warning status).
Emphasis system 36 can provide the default emphasis for each topologic item 54A-D to display system 32, which can render each topologic item 54A-D with the default emphasis in display area 52 using any known solution. For example, topologic item 54C is shown as a solid line while topologic item 54B is shown as a dashed line. In this case, topologic item 54C can have a higher default emphasis (e.g., opacity) than topologic item 54B. It is understood that various alternatives can be used in conjunction with or alternative to opacity. For example, the color, brightness, size, etc. of topologic items 54A-D can be altered based on the default emphasis.
The invention further provides a user-selectable baseline that can be used to generate the content of display area 52. In one embodiment, baseline system 38 can obtain a default baseline that is used to generate the display for topology 16 and provide the default baseline to emphasis system 38 for use in determining the default emphasis. The baseline comprises an alteration that is applied to the emphasis that is determined based on the status information for one or more topologic items 54A-D. To this extent, the baseline can be used to add and/or subtract from the emphasis for one or more topologic items 54A-D. In one embodiment, the same baseline can be applied to all topologic items 54A-D that are displayed in display area 52. In addition to or alternative to a single baseline, a plurality of baselines that are applied to topologic items 54A-D that share a common attribute can be used. For example, a baseline can be provided for one or more types of network resources (e.g., printer, router, connection, etc.), network resources in a particular geographic location (e.g., offices at Armonk, N.Y.), and the like.
In any event, emphasis system 36 can adjust the emphasis for each topologic item 54A-D based on the baseline(s) for the corresponding network resource. For example, as discussed above, the emphasis can comprise a percent opacity with which the topologic item 54A-D is to be rendered (displayed). In this case, baseline system 38 can obtain a default baseline that also comprises a percent opacity, and emphasis system 36 can add the baseline percent opacity to the percent opacity that is determined based on the set of emphasis criteria (e.g., importance, status).
When the emphasis can have a value within a predefined range of values (e.g., a percentage ranging between zero and one hundred percent), emphasis system 36 may need to adjust the calculated emphasis to a value within the predefined range of values. For example, continuing with the example discussed above, the calculation of an emphasis for a router (forty percent opacity) having a critical status (forty percent opacity) with a baseline of fifty percent would yield an opacity of one hundred ten percent. In this case, emphasis system 36 could adjust the opacity to one hundred percent. As a result, the baseline can enable additional topologic items 54A-D to be displayed at full opacity, thereby effectively adding topologic items 54A-D to a set of topologic items that are fully emphasized within display area 52.
User 12 can selectively alter the baseline(s) for a topology 16 while viewing the topology in display area 52. To this extent, baseline system 38 can receive an adjusted baseline for topology 16 that is selected by user 12. User 12 can specify the baseline using any known solution. For example, user interface 50 is further shown including a baseline selection area 56 that enables user 12 to adjust two baselines. In particular, baseline system 38 can display two slider bars 58A-B, each having a slider 60 initially positioned at a location that corresponds to a default baseline (e.g., zero). In this case, slider bar 58A can enable user 12 to selectively adjust a baseline that is applied to all topologic items 54A-D displayed in display area 52, while slider bar 58B can enable user 12 to selectively adjust a baseline that is applied to each topologic item 54B-C that corresponds to a connection. In any event, each slider bar 58A-B can comprise various locations that correspond to different baseline values (e.g., negative one hundred to one hundred percent). Baseline system 38 can receive a user command generated by user 12 to move slider 60 to a new location on slider bar 58A, and determine the adjusted baseline based on the new location in a known fashion.
Baseline system 38 can provide the adjusted baseline to adjustment system 40, which can generate an adjusted emphasis for one or more topologic items 54A-D based on the adjusted baseline. In particular, adjustment system 40 can obtain from emphasis system 36 an emphasis that was calculated based on the set of emphasis criteria for each topologic item 54A-D that corresponds to the adjusted baseline. Subsequently, adjustment system 40 can adjust the emphasis using the adjusted baseline. For example, when the emphasis and baseline comprise an opacity, adjustment system 40 can add the adjusted baseline to the emphasis to determine an opacity and, if necessary, adjust the value to fall within an acceptable range of values for the opacity.
Subsequently, display system 32 can redisplay each topologic item 54A-D based on the adjusted baseline. In particular, adjustment system 40 can provide the adjusted emphasis to display system 32 which can render the corresponding topologic item 54A-D with the adjusted emphasis. For example, as shown in
As a result, the invention enables user 12 to dynamically select a desired level of emphasis for one or more topologic items 54A-D when viewing topology 16. It is understood that various additional functions can be provided to user 12 to further customize a view of topology 16. For example, as shown in
While the invention has been shown and described primarily with reference to a network topology, it is understood that the teachings of the invention are not limited to this application. For example,
It is understood that the teachings of the invention can be applied to various graphical depictions. For example, in addition to systems management and mapping views, the invention can be applied to blueprint software, computer-aided design software, etc. In general, the teachings of the invention can be applied to any graphical interface that depicts information of varied levels of importance combined with varied levels of status. However, it is understood that alternative and/or additional attributes of topologic items can be used to determine various levels of emphasis, such as location information, time information (e.g., how long a network resource been in a critical state), etc.
The invention further includes a method of displaying topology 16 (
