Using Communication Redundancy

Setting up Communication Redundancy on your network helps protect critical links against failure, protects against network loops, and keeps network downtime at a minimum.

The Communication Redundancy function allows the user to set up redundant loops in the network to provide a backup data transmission route in the event that a cable is inadvertently disconnected or damaged. This feature is particularly important for industrial applications, since it could take several minutes to locate the disconnected or severed cable. For example, if the EDS is used as a key communications component of a production line, several minutes of downtime could result in a big loss in production and revenue. The EDS supports three different protocols to support this communication redundancy function—Rapid Spanning Tree/ Spanning Tree Protocol (IEEE 802.1W/1D), Turbo Ring, and Turbo Ring V2.

When configuring a redundant ring, all switches on the same ring must be configured to use the same redundancy protocol. You cannot mix the “Turbo Ring,” “Turbo Ring V2,” and STP/RSTP protocols on the same ring. The following table lists the key differences between each feature. Use this information to evaluate the benefits of each, and then determine which features are most suitable for your network.

NOTE

Most of Moxa’s managed switches now support two proprietary Turbo Ring protocols:

(1)“Turbo Ring” refers to the original version of Moxa’s proprietary redundant ring protocol, which has a recovery time of under 300 ms.

(2)“Turbo Ring V2” refers to the new generation Turbo Ring, which has a recovery time of under 20 ms.

In this manual, we use the terminology “Turbo Ring” ring and “Turbo Ring V2” ring to differentiate between rings configured for one or the other of these protocols.

The Turbo Ring Concept

Moxa developed the proprietary Turbo Ring protocol to optimize communication redundancy and achieve a faster recovery time on the network.

The Turbo Ring and Turbo Ring V2 protocols identify one switch as the master of the network, and then automatically block packets from traveling through any of the network’s redundant loops.
