IEC 61850 traffic engineering

IEC 61850 traffic engineering for GOOSE, SV and MMS

GOOSE and Sampled Values are multicast and latency-critical. Synapse models the substation and DER communications as first-class data flows so you can engineer the traffic — VLANs, priority, redundancy — and prove it performs.

Make multicast deterministic

Excessive or mis-segmented GOOSE/SV traffic overloads IED ports and breaks protection timing. Traffic engineering — VLAN segregation, priority tagging and topology design — keeps the right messages on the right paths within the IEC 61850 3 ms budget.

  • GOOSE, Sampled Values and MMS modelled as explicit flows with protocol and direction
  • VLANs, trunking, PRP and RSTP designed for deterministic, resilient delivery
  • Priority (0–7) separation so protection traffic is never starved

Tie comms design to security

The same model that engineers the traffic checks the segmentation. So your 61850 network is fast and defensible — and the as-designed record never drifts from the security architecture.

Frequently asked questions

What is IEC 61850 traffic engineering?+

It is the design of a substation or DER Ethernet network so that IEC 61850 messages — GOOSE, Sampled Values and MMS — are delivered deterministically. It covers VLAN segregation, priority tagging, bandwidth and redundancy (PRP/RSTP) to meet the standard's timing requirements.

Why is GOOSE traffic challenging to network?+

GOOSE is multicast and time-critical: end-to-end delay for protection should stay under 3 ms. Without VLAN segregation and priority, GOOSE can flood ports and disrupt protection. Careful traffic engineering keeps it contained and prompt.

What is PRP and RSTP used for?+

PRP (Parallel Redundancy Protocol) sends duplicate frames over two independent LANs for zero-recovery-time redundancy; RSTP reconverges a switched topology after a link failure. Both are common in IEC 61850 networks to keep protection and control available.
