This paper examines the use of videoconferencing systems for production (metallurgical) site management. Such systems help achieve a significant reduction in costs associated with meetings and related business trips. Application of such systems was especially wide-spread during the Covid-19 pandemic. However, none of the existing systems takes into account certain features typical of the corporate network infrastructure. Sophisticated communication systems consisting of various segments, as well as of symmetric and asymmetric channels with multiple parameters, which may vary numerous times, make it more difficult to build efficient VoIP solutions, especially when growing videoconferencing services. As the typical approach to securing confidentiality when transmitting voice and video data across communication networks implies that every sender-receiver route is considered public, it loses the benefits of network topology control in the corporate sector. At the same time, the typical client-server architecture across corporate IP networks demonstrates lower performance when compared with peer-to-peer networking because of lesser use of network infrastructure knowledge. The authors propose a new approach to building secured corporate communication systems, which does not have at its basis the client-server architecture but rather a p2p architecture. The latter enables to take into account the existing corporate network structure (including that of a metallurgical company), unload external and internal communication channels and reduce the computing costs at the host level.
