Abstract

A computer is provided with a network planning facility, which displays in map form a network comprising a plurality of nodes each serving a plurality of subtending nodes, and in which the network is characterized by data stored in the computer. The operation of the planning facility is initiated in response to a user entering an appropriate command. Specifically, responsive to the command, the computer displays a plurality of symbols representing respective ones of the nodes, in which each such symbol is arranged so that it is indicative of the number of traffic terminations at its associated node. The user may then select, in a conventional manner, one of the displayed symbols and then invoke either an automatic mode or a manual mode. In the automatic mode, the computer itself develops a plan for rehoming to another network node individual ones of the subtending nodes associated with the selected node, in which the rehomed subtending nodes are selected based on their having a predetermined traffic relationship with the other node. In the manual mode, it is the user, rather than the computer, which develops the rehoming plan.

Claims

1. A dynamic graphics arrangement for use in a computer having a display, said display being employed to display data characterizing a predetermined network formed from a plurality of subtending nodes and a plurality of concentration nodes, said arrangement comprising

means, responsive to receipt of a predetermined request inputted by a user of said computer, for displaying on said display a plurality of symbols representing respective ones of said subtending and concentration nodes, ones of said displayed subtending nodes being assigned to at least a first one of said displayed concentration nodes, said ones of said subtending nodes having respective traffic relationships with said first concentration node and with at least another second one of said concentration nodes, in which each of said traffic relationships is characterized by a respective level,

means, responsive to said user selecting said first concentration node, for determining which ones of the subtending nodes have a higher level of said traffic relationship with said second concentration node than with said first concentration node and for then reassigning those of said ones of said subtending nodes having said higher level to said second node, and

means for displaying on said display the effect of said reassignment.

2. The arrangement set forth in claim 1 wherein said means for determining includes means selectable by said user for causing said computer, rather than said user, to select one of said concentration nodes.

3. The arrangement set forth in claim 2 wherein said means for displaying includes means for displaying on said display a plurality of parameters each having a range of weights settable by said user, said computer using the value of the weight set by said user for each of said parameters to select which ones of said subtending nodes will be reassigned to the other concentration node that said computer selects.

4. The arrangement set forth in claim 3 wherein one of said parameters is said traffic relationship.

5. The arrangement set forth in claim 2 wherein said means for causing includes means for displaying a request for said user to enter a value indicative of the level by which said one concentration node is to be deloaded.

6. The arrangement set forth in claim 2 wherein said means for causing includes means for displaying on said display an auto button selectable by said user for invoking said means for causing.

7. The arrangement set forth in claim 1 wherein said arrangement further comprises means for displaying on said display text detailing the assignment of said ones of said subtending nodes to said second node.

8. The arrangement set forth in claim 1 wherein said arrangement further comprises means for displaying on said display information detailing the level of deloading that may be experienced by said first concentration node as a result of reassigning said ones of said subtending nodes to said second concentration node.

9. The arrangement set forth in claim 1 wherein said means for displaying includes means for displaying on said display a scrollable list identifying each of said concentration nodes, and wherein said user selects said first concentration node by highlighting the identity of said first concentration node when it is displayed in said scrollable list.

10. The arrangement set forth in claim 9 wherein said means for displaying said scrollable list includes means for displaying loading information on said display, including at least memory capacity, processor capacity and number of trunk terminations associated with said highlighted node.

11. A method of displaying on a display associated with a computer the effect of deloading a communications node, said display being employed to display data characterizing a predetermined network comprising a plurality of communications nodes including concentration and subtending nodes, said method comprising the steps of

responding to receipt of a predetermined request inputted by a user of said computer by displaying on said display a plurality of symbols representing respective ones of said concentration and subtending nodes, each of said concentration nodes being associated with a plurality of said subtending nodes, said subtending nodes having predetermined traffic relationships with their associated concentration node and with at least another one of said concentration nodes, in which each of said traffic relationships is characterized by a respective level,

responding to said user selecting one of said concentration nodes by determining which ones of the subtending nodes associated with said selected concentration node have a higher level of said traffic relationship with said at least one other concentration node than with said selected concentration node, and

reassigning those of said ones of the subtending nodes having said higher level to said at least one other concentration node.

12. The method set forth in claim 11 wherein said step of determining includes the step of causing said computer, rather than said user, to select one of said nodes.

13. The method set forth in claim 12 wherein said step of displaying includes the step of displaying on said display a plurality of parameters each having a range of weights settable by said user, said computer using the value of the weight set by said user for each of said parameters to select which ones of said subtending nodes that will be assigned to the concentration node selected by said computer.

14. The method set forth in claim 13 wherein one of said settable parameters is said traffic relationship.

15. The method set forth in claim 12 wherein said step of causing includes the step of displaying a request for said user to enter a value indicative of the level by which said said computer selected concentration node is to be deloaded.

16. The method set forth in claim 12 wherein said step of causing includes the step of displaying on said display an auto button selectable by said user for invoking said means for causing.

17. The method set forth in claim 11 further comprising the step of displaying at a predetermined location on said display text detailing the assignment of said ones of said subtending nodes to said computer selected concentration node.

18. The method set forth in claim 11 wherein said method further comprises the step of displaying on said display information detailing t level of deloading that may be obtained at said selected concentration node as a result of reassigning said ones of said subtending nodes to said other concentration node.

19. The method set forth in claim 11 wherein said step of displaying includes the step of displaying on said display a scrollable list identifying each of said concentration nodes, and wherein said user selects said one concentration node by highlighting the identity of said one concentration node when it is displayed in said scrollable list.

20. The method set forth in claim 19 wherein said step of displaying said scrollable list includes the step of displaying loading information, including at least memory capacity, processor capacity and number of trunk terminations associated with said highlighted concentration node.
