X-Ring Application
The industrial switch supports the X-Ring protocol that can help the network system
recover 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)
and Rapid STP (RSTP) algorithm but its recovery time is less than STP/RSTP. The figure
below is a sample of X-Ring application.
Coupling Ring Application
In the network, it may have more than one X-Ring group. Using the coupling ring function
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.
