Turbo Ring v2
Turbo Ring v2 Overview
Moxa Turbo Ring is a proprietary self-healing technology that enables fast fault recovery of under 20 ms for
Fast Ethernet, and 50 ms for Gigabit Ethernet. Turbo Ring supports two topology expansions—ring coupling
and dual-ring—to reduce redundant network cabling and network planning costs and to ensure high
reliability of your industrial network applications.
The Turbo Ring v2 protocols identify one switch as the master of the network, and then automatically block
one port beside master on the ring (red line) to avoid network’s redundant loops. In the event that one
branch of the ring gets disconnected from the rest of the network, the protocol automatically readjusts the
ring so that the part of the network that was disconnected can reestablish contact with the rest of the
network.
How Turbo Ring v2 Works
Turbo Ring v2 is an advanced technology for network redundancy, which ensures recovery times of less
than 20 ms for Fast Ethernet, and 50 ms for Gigabit Ethernet when the network is down. In addition, it
allows more switches within the network rings. Users can select different network typologies for Turbo Ring
redundancy to allow more network reliability and reduce cabling costs. Below are three examples of how
Turbo Ring v2 works.
Ring Coupling
Ring Coupling helps users separate distributed devices into different smaller redundant rings, but in such a
way that the smaller rings at different remote sites will be able to communicate with each other. This is
useful for applications where some devices are located at remote sites.
