Method for transferring real-time data from one subscriber to another subscriber of real-time Ethernet networks, involves transmitting real-time message from subscriber at real-time router in a real-time Ethernet network

摘要

The method involves transmitting a real-time message from a subscriber (2) at a real-time router (5) in a real-time Ethernet network (4). The real-time message includes a Medium access control (MAC) address of one subscriber, a destination information of another subscriber (11) and a real-time record. A destination Internet protocol (IP) address of another real-time router (7) in another real-time Ethernet network (8) is determined by the former real-time router based on the destination information. The source information, destination information and the real-time data set are encapsulated in an IP message. Another MAC adress of latter subscriber is detremined by latter real-time router. An independent claim is included for a real-time router for automation system for connecting a real-time Ethernet network with a non-real-time Internet protocol network.
