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 Technology : |
|
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.

| Open-Ring Technology : |
|
Open-Ring is an enhanced redundancy technology that makes ORing’s switches compatible with other vendor’s proprietary redundant ring technologies. It enables ORing’s switches to form a single ring with other vendor’s switch. In cases where the ring is setup using proprietary technology, ORing offers a compatibility service where ORing can make its switches compatible with your particular network requirements.

| O-RSTP Technology : |
|
O-RSTP supports more complex topologies and can be applied to more application, while still maintaining a recover time of less than 20 milliseconds. O-RSTP is an enhanced version of RSTP that supports applications with complex topologies. Different from the RSTP standard as defined by IEEE 802.1w, O-RSTP provides faster recover time and allows up to 40 nodes to operate in any topologies. The two main advantages are as the followings:
(1) Improves recover time to less than 20 milliseconds
(2) Can be applied to the same complex topologies like RSTP.
