Self-healing hierarchical network management system, and methods and apparatus therefor
First Claim
1. A method for managing a network, comprising:
- arranging a plurality of network management system (NMS) managers in a hierarchy, said hierarchy having at least a root level and a leaf level, wherein each non-leaf level NMS manager supervises at least one child NMS manager and each leaf-level NMS manager supervises one or more network nodes;
determining when a given NMS manager ceases to operate; and
electing another NMS manager within said hierarchy to assume the responsibility of the non-operating NMS manager.

Abstract
A hierarchical network management system (NMS) in which a plurality of NMS managers, each responsible for different portions or aggregations of a communications network, are logically arranged in a tree structure. The NMS managers are further organized into various sub-groups. The NMS managers within each sub-group monitor the status of one another in order to detect when one of them is no longer operational. If this happens, the remaining operational NMS managers of the sub-group collectively elect one of them to assume the responsibility of the non-operational NMS manager. The NMS is thus “self-healing” in the sense that one NMS manager can dynamically, without operator intervention, assume the responsibilities for another NMS manager.
