Turbo Ring

We developed the proprietary Turbo Ring protocol to achieve
optimization of communication redundancy and faster recovery time on
the network. Our test report shows that the recovery time of Turbo Ring is
less than 300 ms with a full load of 120 nodes of network traffic.
Turbo Ring protocol identifies one switch as the "master" of the network,
and then automatically blocks packets from traveling through any of the
network's redundant loops. In the event that one branch of this ring
becomes disconnected from the rest of the network, the Turbo Ring
protocol automatically readjusts the ring (if possible) so that the part of
the network that was disconnected can reestablish contact with the rest of
the network. The actual topology of the redundant ring, i.e., which
segment will be blocked, is determined by the number of EDSs that make
up the ring.
For some systems, it may not be convenient to connect all devices in the
system to create one BIG redundant ring, since some devices could be
located at a remote site. Turbo Ring's "Ring Coupling" function helps
you separate those distributed devices into different smaller redundant
rings, but in such a way that they can still communicate with each other.
NOTE Ring Coupling and Ring Master do not need to be set up on
the same EDS.
