Chapter 4  Network Application
This chapter provides some sample applications to help user to have more actual idea of industrial switch 
function application. A sample application of the industrial switch is shown as below:
4.1  X-Ring Application
The industrial switch supports the 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.
