Abstract

A network mapping tool efficiently organizes and displays topology data of an internetwork computing system as a hierarchical collection of network maps, i.e., a network atlas. The tool includes a management server that collects, organizes and records the topology data as an atlas on a network topology database. A management console interacts with the server to provide a graphical user interface for displaying the atlas on a computer screen in a variety of views that facilitate comprehension of logical relationships between various components of the system.

Claims

1. A network mapping tool comprising:

a management server for organizing topology data of an internetwork computing system as an atlas of maps on a network topology database; and

an atlas viewer interacting with the management server to display selected maps of the atlas on a specialized viewer window of a computer screen in a variety of views that facilitate comprehension of logical relationships between various components of the system, the viewer window comprising a browser for displaying a list of map names and a display pane for graphically displaying the contents of a selected map on the screen;

wherein said atlas viewer also interacts with said management server so as to permit user editing of said selected map in said display pane by user manipulation of the graphically-displayed contents using a pointing device, and so as to permit visual highlighting of at least certain of the graphically-displayed contents of said selected map to indicate areas where specific protocols are routed.

2. The network mapping tool of claim 1 wherein the management server comprises an atlas manager for coordinating access to the topology database for editing and viewing the atlas maps.

3. The network mapping tool of claim 2 wherein the atlas manager comprises an atlas creator for creating the atlas from the topology data and a layout manager for executing layout operations that enable display of the created atlas maps in a manner that is visually appealing to a user.

4. The network mapping tool of claim 3 wherein the browser allows the user to easily switch between maps displayed on the display pane by positioning a pointer on the corresponding map name and clicking a mouse button.

5. The network mapping tool of claim 4 wherein the contents of a selected map comprises cross-reference icons and wherein the browser further allows the user to easily switch between maps displayed on the display pane by positioning the pointer on a selected cross-reference icon and double-clicking the mouse button to display a map corresponding to the cross-reference icon without losing context of the corresponding map.

6. The network mapping tool of claim 5 wherein a selected map comprises a connected graph of linked router and segment nodes, the nodes being represented by network atlas objects.

7. The network mapping tool of claim 6 wherein the objects are further displayed as icons at various locations on the selected map and links coupling the icons are displayed as lines.

8. The network mapping tool of claim 1 wherein each map of the atlas depicts a page of the internetwork computing system, and wherein at least one top-level page illustrates a WAN structure of the system with at least one subordinate-level page illustrating structures of LAN-connected areas of the system.

9. The network mapping tool of claim 1 wherein said highlighting comprises displaying a colored line along the at least certain contents.

10. A method for constructing an atlas of maps using a network mapping tool having a topology database, the network mapping tool including a management server computer coupled to an internetwork computing system, the method comprising the steps of:

A. invoking an atlas creator component of the management server;

B. enumerating segments and routers stored in the topology database using the atlas creator;

C. classifying each enumerated segment as one of a WAN and LAN segment;

D. creating at least one WAN page and LAN-connected area page in response to Step C;

E. anchoring a router to the WAN page if the router interfaces with at least one WAN segment;

F. anchoring adjacent LAN-connected area pages to each other to generate cross-reference pages;

whereby, an atlas is constructed having at least one top-level page graphically displaying a WAN structure of the computing system and at least one subordinate-level page graphically displaying structures of LAN-connected areas of the system;

G. editing at least one of said area pages based upon user manipulation of at least one graphically-displayed component of said structures, using a pointing device; and

H. visually highlighting at least certain graphically-displayed components of said structures to indicate areas in said computing system where specific protocols are routed.

11. The method of claim 10 wherein said highlighting comprises displaying playing a colored line along the at least certain components.
