Abstract
The present disclosure provides line flapping detection systems and methods for optical networks using, for example, Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), Optical Transport Network (OTN), and the like. Line flapping includes conditions, failures, etc. on a particular line going in and out of failure without raising an alarm or the like. The line flapping detection systems and methods provide configurable settings to set an alarm when it has been determined that a line is indeed flapping. First, there is a two level hierarchical control mechanism used to determine whether to report the alarm. Additionally, the line flapping detection systems and methods are configured to correlate events to count as single line failures instead of a plurality of distinct events.
