1. A method, in a layer of a network, management system, 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 performance monitoring data gathered for section, line and path entities by a plurality of monitoring points during, a monitoring period, each of said plurality of monitoring points being associated with a network element; and
(2) identifying a correlation between any error activity in said section, line and path entities as indicated by said performance monitoring data that is received from at least two different ones of said plurality of monitoring points to locate a root cause of a problem in either said section, line or path entities of 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.

13. A system 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, comprising:
-
(1) means for receiving performance monitoring data gathered for section, line and path entities from a plurality of monitoring points during a monitoring period, each of said plurality of monitoring points being associated with a network element; and (2) means for identifying a correlation between any error activity in said section, line and path entities as indicated by said performance monitoring data that is received from at least two different ones of said plurality of monitoring points to identify a root cause of a problem in either said section, line or path entities of the provisioned channel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A computer program product, comprising:
-
a computer usable system 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 causing a computer to effect a reception of performance monitoring data gathered for section, line and path entities from a plurality of monitoring points during a monitoring period, each of said plurality of monitoring points being associated with a network element; and second computer readable program code means for causing a computer to effect an identification of a correlation between any error activity in said section, line and path entities as indicated by said performance monitoring data that is received from at least two different ones of said plurality of monitoring points to identify a root cause of a problem in either said section, line or path entities of the provisioned channel.
