Change Point Detection in Network Traffic Time Series

Change Point Detection in Network Traffic Time Series
Abstract:
Change point v časovej rade popisujúcej tok dát v sieti môže byť príznakom dôležitej udalosti a preto algoritmy na detekciu change pointov nachádzajú uplatnenie v monitorovaní sietí. V tejto práci sú otestované štyri metódy detekcie changepointov - CUSUM diagram, ChangeFinder, uLSIF a jednoduchý algoritmus, ktorého účelom je uľahčiť hodnotenie ostatných metód - na časových radách zo skutočných sieťových …more
Abstract:
A change point in a network time series might be a sign of an important event happening in a network, and therefore algorithms for change point detection could be applied in network monitoring. Four change point detection methods - CUSUM chart, ChangeFinder, uLSIF and a simple baseline method for benchmarking - were tested on time series based on real-world network flows into which change points were …more
