3.1 Rapid Ring Application
The industrial Switch supports the Rapid Ring (X-Ring) protocol that can help the network system to recovery from
network connection failure within 20ms or less, and make the network system more reliable. The X-Ring algorithm is
similar to spanning tree protocol (STP)
algorithm but its recovery time is faster than STP. The following figure is a sample
X-Ring application.
3.2 Coupling Ring Application
In the network, it may have more than one X-Ring group. By using the coupling ring function, it can connect each X-Ring
for the redundant backup. It can ensure the transmissions between two ring groups not to fail. The following figure is a
sample of coupling ring application.
