ABSTRACT:
A route convergence monitoring system and method provide for determining routing changes or affected devices that may cause detrimental or other quality conditions to occur in an endpoint device. In one embodiment, ongoing endpoint quality monitoring of quality conditions and convergence occurrence monitoring of successive route changes that may occur are initiated. An endpoint quality monitor provides for determining an endpoint quality condition and transferring an indicator of the condition (e.g., endpoint device and timing) to a network manager. The network manager may add one or more information indicators and provides the indicators to an end-to-end convergence monitor. The convergence monitor, receives the indicators and determines one or more of a second endpoint device, routing changes in at least a portion of the network and a correlation of routing changes that may have caused the indicated or other quality conditions to occur.
