Title:
時間トリガーおよびイベント・トリガー・イーサーネット・メッセージの伝送のための通信方法およびシステム
Document Type and Number:
Japanese Patent JP2005536084
Kind Code:
A
Abstract:
A communication method for transmitting Ethernet messages in a distributed real-time system in which a plurality of network node computers, e.g. four network node computers (111, 112, 113, 114), each comprising at least one communication controller (121, 122, 123, 124), are linked via a communication system comprising one or more communication channels (109), one or more intelligent star couplers (101, 102) being disposed in each communication channel. According to the invention, a distinction is made between conventional Ethernet messages (ET messages) and time-triggered Ethernet messages (TT messages), the TT messages being transported with an a priori known constant delay time (Δ) between transmitter and receiver, and, when there is a time conflict between ET and TT messages, the transport of the ET message that is in conflict being delayed or aborted in order to be able to transport the TT message with the constant delay time (Δ). Furthermore, the invention relates to a corresponding communication system and a star coupler for such a communication system.
