Hiper-Ring - Hirschmann RS20 Reference Manual

Redundancy

7.1 HIPER-Ring

The concept of the HIPER-Ring enables the construction of high-availability,
ring-shaped network structures.
Using the RM function (Redundancy Manager) of a device with the L2E, L2P,
L3E or L3P software, you can close both ends of a backbone in a line struc-
ture to a redundant ring, the HIPER-Ring.
Within a HIPER-Ring Version 1, any combination of RS1, RS2-../.., RS2-
16M, RS2-4R, RS20, RS30, RS40, MICE, PowerMICE, MS 20, MS 30,
RSR20, RSR30, MACH 1000, MACH 3000 and MACH 4000 is possible.
Within a HIPER-Ring Version 2 (MRP Draft), any combination of devices that
support this function is possible.
Within a HIPER-Ring Version 3, any combination of RSR20, RSR30 and
MACH 1000 is possible.
If a section is down, the ring structure of a
HIPER-Ring Version 1 of up to 50 devices typically transforms back to a
line structure within 150 ms (adjustable to max. 300 ms/500 ms).
HIPER-Ring Version 2 of up to 50 devices typically transforms back to a
line structure within 150 ms (adjustable to max. 200 ms/500 ms).
HIPER-Ring Version 3 of up to 5 devices typically transforms back to a
line structure within 5 ms (maximum 10 ms). If a larger number of devices
is being used, the reconfiguration time increases.
