Анализ метода обнаружения сетевых аномальных выбросов трафика с помощью алгоритма Бродского-Дарховского

Abstract

In this paper we are considering algorithms of detection of network anomaly burst with method of disorder by Brodsky-Darkhovsky. As a processed statistic we are used Brodsky-Darkhovsky’s generalized statistic, used for the test of mach/mismatch for the mean value in two sliding windows. Conducted simulations of attacks on telecommunication system and their detection using this algorithm. Identified the critical values of noise for normal mode and the sliding window in which the algorithm ceases to function properly. The practical examples with a clear illustration of the algorithm is applied.
