Redundancy
Redundancy for minimized system downtime is one of the most important concerns for critical mission
networking devices. PureLink provides redundancy technologies including O-Ring, O-RSTP, and Open-
Ring featuring faster recovery time than existing redundancy technologies widely used in commercial
applications, such as STP, RSTP, and MSTP. These redundancy technologies not only support different
networking topologies, but also assure the reliability of the network.
O-Ring
O-Ring technology provides recovery time of less than 10 milliseconds and up to 250 nodes. The ring
protocols identify one switch as the master of the network, and then automatically block packets from
traveling through any of the network’s redundant loops. If one branch of the ring gets disconnected from
the rest of the network, the protocol automatically readjusts the ring so that the part of the network that was
disconnected can reestablish contact with the rest of the network. The O-Ring redundant ring technology
can protect mission-critical applications from network interruptions or temporary malfunction with its fast
recover technology.
