Turbo Ring with even number of switches
If the number of Ethernet switches in the
Turbo Ring is 2N (an even number), the
backup segment is one of the two segments
connected to the (N+1)st switch (i.e., the unit
directly opposite the master).
Turbo Ring with odd number switches
If the number of Ethernet switches in the
Turbo Ring is 2N+1 (an odd number), the
backup segment is the (N+1)st segment
counting counterclockwise.
For the example shown here, N=1, so that
N+1=2.
