PECULIARITIES OF COMPUTER NETWORK FUNCTIONING TO MAINTAIN INFORMATION SYSTEM OF FORENSIC ACTIVITY

Abstract

The analysis of the quality control of data transmission process in computer network of the forensic information system is carried out. The role of a specialized network in the information system of forensic science in Ukraine is determined. The causes that lead to overload and packet loss in data transfer networks of the information system are analyzed. Quite high requirements are imposed on modern computer networks, but, unfortunately, in conditions of limited funding and of a variety of sectoral informatization programs (typical for the present realia of Ukraine), most computer networks are heterogeneous, that is they consist of various software and hardware under various operating systems and provide consumers with a wide range of information services. Due to rapid growth in the volume of information, load on computer network keep significantly increasing. A single error in computer network operation may lead either to loss of information or to modification of a large amount of data. It can drastically reduce the quality and efficiency of forensic examination. Unfortunately, such errors can be undetected for many reasons: software and/or hardware failure, incorrect administration, etc. Software bugs are highly dangerous (buffer overflow, program crash, system overload, gaining administrator rights). There is a need to manage data transfer process. To improve the quality of computer network functioning, it is proposed to create a system for evaluating network parameters. As a result of theoretical studies on network bandwidth controlled by the TCP protocol, based on an approach aimed at studying the network structure, a new way to control network’s computational capacity is suggested as well as it is also established that the suggested system for evaluating network parameters of the forensic information system allows you to determine location of telecommunication network segments with limited bandwidth.

Using STAB allows you to accurately assess the available channel bandwidth, due to its calculation to m connections at any time. Thus, it will help to develop alternative virtual routes which will significantly reduce the number of lost packets and, ultimately, improve the quality of information transfer in the computer network of the forensic information system.
