1. A method for identifying a root cause of a problem in a provisioned channel in a network, the provisioned channel being routed through a plurality of network elements, the method comprising the steps of:
- (1) receiving, in a layer of a network management system, a plurality of problem alert signals from a plurality of monitoring points, each of said plurality of monitoring points being associated with a network element in the network that is being monitored by said network management system, each of said plurality of problem alert signals being generated by a monitoring point based upon the analysis of performance monitoring data recorded for a section, line or path entity during a monitoring period; and
(2) identifying, in a layer of a network management system, a correlation between said plurality of problem alert signals to identify a root cause of a problem in the provisioned channel.

Abstract
A system and method for determining a root cause of error activity in a network is described herein. Root cause analysis includes the correlation between reported error activity for path, line and section entities along a provisioned channel in the network. Root causes can also be identified based upon the correlation of simultaneous error activity on various signal transport levels. Finally, root cause analysis can correlate error activity along various path entities.

27. A computer program product for use with a computer system, comprising:
-
a computer usable medium having computer readable program code means embodied in said medium that identifies a root cause of a problem in a provisioned channel in a network, the provisioned channel being routed through a plurality of network elements, said computer readable program code means comprising; first computer readable program code means for enabling the computer system to effect a reception, in a layer of a network management system, of a plurality of problem alert signals from a plurality of monitoring points, each of said plurality of monitoring points being associated with a network element in the network that is being monitored by said network management system, each of said plurality of problem alert signals being generated by a monitoring point based upon the analysis of performance monitoring data recorded for a section, line or path entity during a monitoring period; and second computer readable program code means for enabling the computer system to effect an identification, in a layer of a network management system, of a correlation between said plurality of problem alert signals to identify a root cause of a problem in the provisioned channel.
