Abstract From the Canadian patent

A system and method for diagnosing faults in a communication network using a distributed alarm correlation system. The alarm correlation system may include node-level alarm correlation tools (ACTs) located at nodes in the network to provide node- level alarm correlation producing node-level correlation results. The node-level ACTs may share diagnostic knowledge with other node-level alarm correlation tools at other nodes. Each of the node-level ACTs may also share the diagnostic knowledge and the node-level correlation results with a higher-level ACT. The higher-level ACT may provide higher-level alarm correlation to produce higher-level correlation results.

Why it's free to use

  • Filed March 16, 2004 and granted August 13, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 16, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 16, 2026.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
