Automatic device configuration for Ethernet ring redundancy protocols

Abstract

Translate Article

In modern communication systems based on Ethernet technology, the use of physical ring structures and ring redundancy protocols has been common for some time in the past. A challenge remains the configuration of such a redundancy protocol on each device with the networks stretching out over large areas, like in offshore wind power stations, where each windmill houses at least one Ethernet switch. The distance between windmills can be several kilometers and configuration of the redundancy protocol on each device is an elaborate process. In this paper, a mechanism is proposed which automatizes the configuration of ring redundancy protocols and eliminates the need to configure each device separately. The actual protocol implementation is intended to be part of the next major software release of Hirschmann Industrial Ethernet Switches.
