It is possible to process the data using Big Data frameworks, however, such approach requires adaptation or complete redesign of processing tools to get the same results. This paper elaborates on a parallel processing based on splitting a stream of flow records. The goal is to create subsets of traffic that contain enough information for parallel anomaly detection. The paper describes a methodology based on so called witnesses that helps to scale up without any need to modify existing algorithms. %G English %Z TC 6 %Z WG 6.6 %2 https://inria.hal.science/hal-01806065/document %2 https://inria.hal.science/hal-01806065/file/452969_1_En_14_Chapter.pdf %L hal-01806065 %U https://inria.hal.science/hal-01806065 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC6 %~ IFIP-AIMS %~ IFIP-WG6-6 %~ IFIP-LNCS-10356
