Many Ethernet protocols defined by IEEE, such as STP, RSTP, MSTP, are developed to recover from network disconnections. However, the recovery time is much more critical in industrial applications than commercial ones. Due to these needs, industrial networking devices often utilize proprietary redundant ring technologies to minimize the downtime. ORing develops a variety of proprietary redundant ring technologies including O-Ring, O-RSTP, and Open-Ring, etc. These ORing’s proprietary redundant ring technologies not only meet the demands of different networking topologies, but also assure the reliability of the network.
O-Ring is ORing's proprietary redundant ring technology, with recovery time of less than 10 milliseconds and up to 250 nodes. The O-Ring redundant ring technology can protect mission critical applications from network interruptions or temporary malfunction with its fast recover technology
