When the number of EDS units in the Turbo Ring is odd.
If there are 2N+1 EDS units (an odd
number) in the Turbo Ring, with EDS
units and segments labeled
counterclockwise, then segment N+1 will
serve as the backup path.
For the example shown here, N=1, so that
N+1=2.
For some systems, it may not be convenient to connect all devices in the system to make one BIG
redundant ring, since some devices could be located in a remote area. The “Ring Coupling”
function of Turbo Ring can help you separate those distributed devices into different smaller
redundant rings, but in such a way that they can still communicate with each other. The figure
below illustrates how to couple two Turbo Rings.
In the VLAN environment, the user has to set “Redundant Port,” “Coupling Port,” and
“Coupling Control Port” as “Trunk Port.” Since these ports act as the “backbone” to transmit
all packets of different VLANs to different EDS units.
