This Technical Report addresses issues such as Ethernet technology, network topology,
redundancy, traffic latency and quality of service, traffic management by multicast and VLAN,
network-based clock synchronization and testing of the network. It does not address networkbased
security.
The Technical Report is based on existing standards for semantics, services, protocols,
system configuration language and architecture. It is based on work done by IEC TC 57
WG 10 (Power system IED communication and associated data models) and IEC TC 57
WG 15 (Data and communications security), on IEC 61918 (Industrial communication
networks – Installation of communication networks in industrial premises), IEC 62439
(Industrial communication networks – High-availability automation networks) and IEC 61588
(Precision clock synchronization protocol for networked measurement and control systems),
on the work of the IEEE 802.1 Working Group, the UCA International Users Group 9-2LE and
the IEEE Power System Relaying Committee (PSRC), and on contributions by different
companies.
