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.
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.
Initial setup of a “Turbo Ring” or “Turbo Ring V2” ring
1. Select any two ports as redundant ports.
2. Connect the redundant ports to form the
Turbo Ring
The user does not need to configure any of the switches as the master to use Turbo Ring or Turbo
Ring V2. If none of the switches in the ring is configured as the master, then the protocol will
automatically assign master status to one of the switches. In fact, the master is only used to
identify which segment in the redundant ring acts as the backup path. In the following subsections,
we explain how the redundant path is selected for rings configured for Turbo Ring, and Turbo
Ring V2.
Determining the Redundant Path of a “Turbo Ring” Ring
In this case, the redundant segment (i.e., the segment that will be blocked during normal operation)
is determined by the number of EDS units that make up the ring, and where the ring master is
located.
