Performance measurements
Recovery time from single link failure for 9 IEDs + 1 switch is < 45 ms and for 39 IEDs + 1 switch is < 185 ms in
ring topology
GUID-48F45DA2-B92E-4977-B9B8-C2FCE8091624 v1
The recovery time of a link failure on
RSTP with the IEDs that are using
Galvanic ports is higher than the IEDs
with the Optical ports.
