Performance Evaluation of Flow Hog Identification Method
Noriaki Kamiyama, Tatsuya Mori, Ryoichi Kawahara (NTT) IN2006-66
Abstract (in Japanese) (See Japanese page) 
(in English) Worm-infected hosts generate a large number of flows during a short time. We proposed a method identifying hosts that generate many flows, i.e., {\it flow hogs}, using flow sampling. This method consists of a Bloom filter finding a new flow and a host table storing the sampled flow count of each host. We also proposed an optimum memory allocation method for each module to minimize the false negative ratio. To obtain the optimum identification threshold, we need to appropriately estimate the median of flow count for flow hogs. In this paper, we propose a method accurately estimating the median from the host set identified in the previous measurement period. We also show the results of performance comparisons with other methods.
