Abstract
A technique for monitoring performance in a network uses passively monitored traffic data at the server access routers. The technique aggregates performance metrics into clusters according to a spatial hierarchy in the network, and then aggregates performance metrics within spatial clusters to form time series of temporal bins. Representative values from the temporal bins are then analyzed using an enhanced Holt-Winters exponential smoothing algorithm.
