• Samples Must not get lost

• Samples blocking free

• Trip signal, non blocking, highly redundant

• < 1µs Time Sync via the Ethernet

• Client Server for e.g. monitoring

and SV/GOOSE on the same wire/fiber

• Bandwidth Reservation

Guaranteed response times

• Bumpless Redundancy

In the case of interruption not even one telegram gets lost

• < 1µs Time Sync via the Ethernet

IEEE 1588 Precision Time Protocol Redundancy for the time sync

• Real Time and non-Real-Time (TCP/IP) on the same wire/fiber

All signals available at each port

• Conversion IEC 61850-9-2 LE to RTE in a external switch possible

• Other domains have the same requirements and discuss similar solutions

IEEE 802.1avb

• Bumpless redundancy and use of IEEE 1588 is now

discussed in IEC and IEEE PSRC
