IP Flow Filter
Štoffa, Imrich ; Krobot, Pavel (referee) ; Wrona, Jan (advisor)
This thesis is focused on unification of filtering languages used by IP flow collecting program and library for their analysis. At the moment these implementations use different filtering modules and file formats. Because of this, inconsistencies in results arise and as a response to this, creation of one filtering module was proposed as part of effort to better integrate collection and analysis of IP flows using these programs. The one filtering module aims to provide one implementation and support for popular filtering language for use in the programs. Thesis contains theoretical introduction to flow monitoring in networks, describes algorithms useful for evaluation of conditions on flow records and packets. The core of authors work is design and implementation of the filtering module and its wrappers for the collector and analysis library. Results of performance tests and evaluation of features can be found in the thesis's conclusion.
