R200 - Redundant ring

Redundant ring provides the possibility to connect an Ethernet network normally built in a star topology in ring, providing redundant paths in the network. A normal Ethernet switch can not be connected in a ring topology because broadcast and multicast packets will be transmitted from switch to switch in the ring forever. Mechanisms for handling all kinds of network faults is implemented in each of the switches that form the ring, but one is in charge making decisions and taking actions in order to keep the network up even if parts of the network is out of order.

The graphical PC tool makes configuration easy. The ultra-fast topology reconfiguration changes the topology in only 30ms, which is fastest on the market today. Applications sensitive to network interruptions may now perform without temporary loosing functions etc. An example is IP telephony calls that are lost using yesterdays technology but using OnTimes redundant ring switches the caller will not even notice a network fault.

It is critical that the reconfiguration time is shorter than any application timeout otherwise application may need to be restarted or processes may fail. With only 30ms reconfiguration time many more applications can operate reliable during reconfiguration.
Network links can be both single and multimode fiber links.
