A system and method for client network congestion analysis and management is disclosed. According to one embodiment, the method includes: collecting real-time network data; executing calculations on the real-time network data to compute performance metrics; detecting peak usage time; and detecting one or more congestion incidents, wherein a congestion incident comprises a persistence of one or more metrics over a time window that comprises detecting a proportion of metric values crossing a threshold that exceeds a defined percentage amount, detecting a time-ordered stretch of metric values that exceeds a defined threshold, or combinations thereof.
