Method and apparatus for collecting management information on a communication network
First Claim
1. A method for collecting management information on a communication network, the method comprising the steps of:
- obtaining a network technology independent high-level health indicator from a managed network element; and
if details of the high-level health indicator are required, obtaining at least one of a technology independent intermediate-level health indicator and a technology independent raw health indicator related to the technology independent high-level health indicator from the managed network element.

Abstract
A method and apparatus for collecting management information on a communication network enables universal health indicators to be defined so that management information may be presented to a network operator on a management station. The universal health indicators may be defined in a top-down manner such that the definitions of the health indicators may be used across multiple network elements without changing the health indicator definitions. The health indicators may be organized in a tree-like hierarchical structure to enable additional information to be obtained about the health of the reporting network element in a predictable and organized fashion. Network element raw measurements and computed measurements are used to provide data to the health indicators, and are selected on a network technology type or MIB type basis to enable the same health indicators to be supported by multiple network technology types.

8. A network element, comprising:
a processor containing control logic configured to maintain a management information base containing raw measurement information relating to the state of the network element, and configured to implement health definition software configured to compute technology independent raw health indicators from values in the management information base. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of defining technology independent health indicators for collecting health information from network elements of diverse technologies, the method comprising the steps of:
-
defining a high-level health indicator;
determining a set of raw health indicators required to compute the high-level health indicator; and
for each technology, determining a set of at least one of computed measurements and raw measurements required to compute the raw health indicators. - View Dependent Claims (15)

16. A technology independent health indicator, comprising:
-
a raw health indicator portion configured to indicate the health of an aspect of a managed network element of a first network technology; and
a high-level health indicator portion derived at least in part from the raw health indicator portion and configured to indicate the health of a managed network element; and
wherein the raw health indicator is defined independent of available measurements on the managed network element, but is computed from measurements on the managed network element. - View Dependent Claims (17, 18, 19, 20)
