Xpress Ring
6.14.1.
Introduction
The Xpress-Ring is a fast-acting, self-healing ring recovery technology that enables networks to
recover from link failure within 10ms.
Fast Link Recovery and Ring Redundancy are important features for increasing the reliability of
non-stop systems.
If the network is planned correctly with an arbiter Switch and ring ports, the network will recover
from any segment failure within a very short time.
There are two roles (Forwarder and Arbiter) of the Switch in the Xpress-Ring. There is one and
only one Switch is the Arbiter Switch and the others are the forwarder Switch.
One of the ring ports of the Arbiter Switch will be set to blocking state. When one of the ring
connections is broken, the blocked port will be set to forwarding state.
