Route convergence monitoring system and method

A network monitoring system, comprising

• means for performing quality monitoring of a user device that is coupled to a network for conducting an application;
• means for determining that a quality condition affecting the user device has occurred;
• means for transferring a quality indicator indicating the occurrence of the quality condition;
• means for receiving the quality indicator and a timing indicator indicating a timing of the condition occurrence;
• and
• means for determining, in accordance with the received indicators, one or more network routing changes that may have caused the quality condition affecting the user device.

A machine-readable medium having stored thereon instructions that when executed cause a computer to perform the steps of:

• performing quality monitoring of a user device that is coupled to a network for conducting an application;
• determining that a quality condition affecting the user device has occurred;
• and
• transferring, to an end-to-end convergence monitor, a quality indicator indicating the occurrence of the quality condition and a timing indicator indicating a timing of the condition occurrence.

A network monitoring method, comprising:

• monitoring network routing changes occurring in a network portion;
• storing the monitoring routing changes and a change timing indicators corresponding to the routing changes;
• receiving a quality indicator indicating a quality condition affecting a first endpoint device and a quality timing indicator indicating a timing of the quality condition, the first endpoint device conducting an interaction application with a second endpoint device via the network portion;
• and
• determining one or more routing changes to a network route coupling the first and second endpoint devices that may have caused the quality condition.
