Synthesising TCP data traffic from industrial networks for simulations

Abstract

In this paper, authors deal with a problem of an impaired TCP stream reconstruction from a real-world captured data. The goal is to obtain an original application data. The data are synthesized to be used as an input for a traffic generator. Authors describe a way to solve specific problems at transport and application layers during the reconstruction of an impaired TCP stream. The traffic reconstruction is oriented to IEC 60870-5-104 protocol on top of TCP. The evaluation of proposed algorithms shows that it is possible to estimate original time dependencies between received and dispatched messages with high accuracy.
