Abstract

Способ для использования в распределенной системе, включающей в себя сервер, управляющий основным объемом данных, включающим в себя множество из, по меньшей мере, одного статического атрибута и, по меньшей мере, одного динамического атрибута, преобладающие значения которых в основном объеме данных соответственно обновляются и не обновляются вследствие команды от клиента, и, по меньшей мере, два клиента, управляющих каждый объемом данных, предназначенных для зеркального отражения (точного соответствия) основного объема данных. Предложенный способ обеспечивает восстановление зеркального отражения данных у клиента, только что вновь подключенного к серверу после перерыва в связи.
