A Case Study on Testing LFE Seapath at National Grid Electricity Transmission
summary
A proof of concept between GE Vernova and National Grid Electricity Transmission uses LFE SEAPATH to host virtualized protection and control, bypassing the vSwitch with PCI passthrough and running Docker inside VMs with Zeromq for SV and GOOSE; lab trials run over 44,000+ repetitions record a 5.5 ms average round-trip with tight determinism, showing scalability to ~50 bays, successful HA/clustering experiments, and a preference for fanless Intel servers with pinned cores and IO offload.
