Основными структурными элементами архитектуры являются оптическая гальваническая развязка, медиаконвертеры и прокси-серверы, исключая на аппаратном уровне двунаправленную передачу данных. Работа по однонаправленной передаче данных осуществляется на базе транспортного протокола UDP, обеспечивающего ее без установления двунаправленного взаимодействия. Однонаправленная передача данных производится с прокси-сервера, на котором работает специальное программное обеспечение отправителя, осуществляющее однонаправленную передачу файлов данных, преобразуя их в однонаправленный поток UDP дейтаграмм. Для приема однонаправленного потока UDP дейтаграмм используется прокси-сервер, осуществляющий прием, обработку и формирование исходного файла данных. Достоверность однонаправленной передачи файлов данных обеспечивается путем избыточности (многократной передачи) и проверки контрольной суммы.</p></abstract><trans-abstract xml:lang="en"><p>The results of a study of the architecture of hardware and software for unidirectional data transmission in computer networks are presented. The architecture is presented in the form of optical galvanic isolation, media converters and proxy servers, excluding bidirectional data transmission at the hardware level. Work on unidirectional data transmission is carried out on the basis of the UDP transport protocol, which provides operation without establishing bidirectional interaction. Unidirectional data transfer is carried out by a proxy server running a special sender’s software that performs unidirectional data file transfer. This software converts the source data file into a unidirectional stream of UDP datagrams. To receive a unidirectional stream of UDP datagrams, a proxy server is used, on which the recipient’s special software is running. The receiving proxy server receives, processes and generates the source data file. The reliability of the unidirectional transmission of data files is ensured by redundancy (multiple transmission) and checksum verification.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>однонаправленная передача данных</kwd><kwd>UDP</kwd><kwd>дейтаграмма</kwd><kwd>оптическая гальваническая развязка</kwd><kwd>прокси-сервер</kwd><kwd>медиаконвертер</kwd><kwd>архитектура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>unidirectional data transmission</kwd><kwd>UDP</kwd><kwd>datagram</kwd><kwd>optical galvanic isolation</kwd><kwd>proxy server</kwd><kwd>media converter</kwd><kwd>architecture</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bell D.
