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-828 units that make up the ring, and where the ring master is located.

“Turbo Ring” rings with an even number of EDS-828 units.

If there are 2N EDS-828 units (an even number) in the

“Turbo Ring” ring, then the backup segment is one of

the two segments connected to the (N+1)st EDS-828

(i.e., the EDS-828 unit directly opposite the master).

“Turbo Ring” rings with an odd number of EDS-828 units.

If there are 2N+1 EDS-828 units (an odd number) in the

“Turbo Ring” ring, with EDS-828 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.

Determining the Redundant Path of a “Turbo Ring V2” Ring.

For a “Turbo Ring V2” ring, the backup segment is the

segment connected to the 2nd redundant port on the

master.

“Turbo Ring” and “Turbo Ring V2” section below.
