The invention relates to network management systems within telecommunication networks, and more particularly to graphical user interfaces of such systems.
In network management tools used in management of hierarchical telecommunication networks, operators work within a network management map display to drill down into layers of network maps to work with or identify network elements. In large networks with many layers, operators can lose track of what location in the network map they are currently viewing. One approach is to use a tree-based display to list previously visited levels. However, such displays use a significant amount of space on the network management map display. Another solution would be to maintain a historical listing of network elements and levels visited, analogously to web browser history listings. However, a historical listing is merely a sequential listing made over time of levels and network elements visited. As different levels are visited repeatedly, such a list may quickly become unworkable.
An interface which allowed operators to easily determine where in the network hierarchy they currently are, and to navigate quickly to higher levels within the hierarchy, would improve the efficiency of hierarchical operations.
In accordance with one aspect of the invention, a method is provided for presenting network object hierarchy information in a network management tool, the network management tool being used in managing a communication network having a hierarchy of network objects. Status information of a displayed network object is displayed on a terminal, the displayed network object having at least one higher-level network object within the hierarchy. An ordered series of buttons is displayed on the terminal, each button corresponding to a network object within the hierarchy and being ordered according to a position within the hierarchy of the corresponding network object. The series of buttons includes at least a displayed network object button corresponding to the displayed network object. On each button, at least a portion of a label indicating the corresponding network object is displayed. A new displayed network object is designated by selecting a network object displayed in the status information or by selecting a button.
The methods may be carried out as part of a network management tool. The methods may be stored as instructions on a computer-readable medium, to be executed by a computer processor.
The methods of the present invention allow an operator of a network management tool to tell at a glance where in the network object hierarchy he or she is currently looking. The breadcrumb buttons indicate the higher levels within the hierarchy, up to the root network object, and allow the operator to quickly select a higher-level network object to move back up the hierarchy.
The features and advantages of the invention will become more apparent from the following detailed description of the preferred embodiment(s) with reference to the attached figures, wherein:
It will be noted that in the attached figures, like features bear similar labels.
A network management tool displays a graphical user interface on a computer display device, and allows an operator to interact with a network management system. The network management tool includes instructions in the form of software for displaying the graphical user interface. The software may be stored on a computer-readable medium. Referring to
The currently displayed network object is part of a hierarchy of network objects within a network. At the top of the hierarchy is a root object, typically representing the entire network. Each breadcrumb button corresponds to a network object, which may be a group of network elements, within the hierarchy. Each breadcrumb button has an associated label, which indicates to which network object the breadcrumb button corresponds. At least a portion of the label is displayed on each breadcrumb button.
The breadcrumb buttons on the breadcrumb bar include a root button corresponding to the root object. The breadcrumb buttons also include a displayed network object button corresponding to the currently displayed network object. Of course, if the currently displayed network object is the root object, then only one breadcrumb button will be displayed. The breadcrumb buttons may also include one or more intermediate buttons. Each intermediate button corresponds to an intermediate network object, located between the currently displayed network object and the root object in the network hierarchy. If the currently displayed network object is the root object or if the currently displayed network object is one level below the root object within the network hierarchy, there will be no intermediate network objects and hence no intermediate buttons.
Broadly then, the breadcrumb bar includes the root button corresponding to the root object, the displayed network object button corresponding to the currently displayed network object (which may be the same as the root button and the root object respectively), and at least one intermediate button if there is as least one intermediate object between the root object and the currently displayed network object, each intermediate button corresponding to an intermediate object. For the purposes of clarity, it will be assumed in the description that follows that there is at least one intermediate object.
The breadcrumb buttons are ordered within the breadcrumb bar according to the respective positions of the corresponding network objects within the network hierarchy. The root button is located at one end of the breadcrumb bar, preferably at the left end. The displayed network object button is located at the other end of the breadcrumb bar, preferably at the right end. The intermediate buttons are arranged such that as the breadcrumb bar is traversed from the root button to the displayed network object button, the corresponding network objects are located successively further from the root object within the network hierarchy. If the root button is at the left end of the breadcrumb bar, then each breadcrumb button will correspond to a network object higher in the hierarchy than the network objects corresponding to breadcrumb buttons to the right of the breadcrumb button. Turning to the example breadcrumb bar 14 shown in
When the operator selects a breadcrumb button, a new currently displayed network object is designated. The operator may also select a new currently displayed network object by other means, such as by clicking on icons within the information region 12. When the operator selects a new currently displayed network object, network object information corresponding to the new currently displayed network object is displayed within the information region 12, and the breadcrumb bar 14 is redrawn. The ordering of the breadcrumb buttons is based entirely on the relative positions of the corresponding network objects within the hierarchy, and does not depend on the order in which the network objects have been selected by an operator. The example breadcrumb bar 14 in
The appearance of the breadcrumb buttons will now be discussed with respect to the preferred embodiment of the invention. As shown in
If there are many intermediate buttons, or if a name of a network object associated with one of the buttons is very long, there may not be sufficient room to display all of the labels in their entirety. In such a case one or more of the labels is truncated and, if the size of the button permits, appended with ellipses. Referring to
The breadcrumb buttons have a minimum width, for example defined so as to be able to display the ‘>’ symbol. If there are so many intermediate buttons that the number of buttons multiplied by the minimum width is longer than the length of the breadcrumb bar, then the extra breadcrumb buttons will be removed and not all intermediate network objects will be represented on the breadcrumb bar. This clipping 22 occurs immediately to the right of the root button. The breadcrumb bar will include the root button 16, the displayed network object button 18, and as many intermediate buttons as will fit within the breadcrumb bar, the intermediate buttons corresponding to those network objects progressively higher within the hierarchy than the currently displayed network object. Referring to
As an alternative to displaying the ‘>’ symbol as part of the label, the breadcrumb buttons may display icons representing respective types of equipment of the corresponding network objects. This allows the operator to quickly identify objects within the network hierarchy.
The embodiments presented are exemplary only and persons skilled in the art would appreciate that variations to the embodiments described above may be made without departing from the spirit of the invention. For example, different icons or symbols can be displayed by the buttons, or different forms of name truncation. The buttons may be arranged vertically or horizontally, anywhere within the window, as long as the buttons are ordered according to the position within the hierarchy of the corresponding network objects. The scope of the invention is solely defined by the appended claims.
