5 Enhanced Features
5.1 Xpress Ring
Xpress Ring is a VOLKTEK proprietary ring protocol that enables networks to recover
from link failure within 50ms. To enable Xpress Ring, it needs some network
configuration: the user must assign two ring ports for each Switch in the ring. The user
must also assign the Arbiter Switch which will decide if it is necessary to activate the
backup path. For Xpress Ring, any switch can be the arbiter – just remember that the
Arbiter Switch must be part of the ring.
Apart from rerouting the transmission within 50ms, the Arbiter Switch will also issue an
alarm when a link failure occurs. The user will then be informed of the failure and will be
able to fix the problem and reconfigure if required.
Xpress Ring is the fastest ring recovery technology and is ideal for networks where the
ring topology is not changed very often.
For configuration of Xpress Rings, please refer to the appropriate chapter in this manual.
