Research Question: Can we use an Internet entity (IXP, DCs) to provide resilience to IEC-61850 networks?

• Target Usecases: We target inter-substation communication usecases:
  • Protection Usecases
    • POTT, PUTT, DCB, Pilotwire, Phase comparison, Line Differential
    • Permissive Overreaching Transfer Trip (POTT)
    • Permissive Underreaching Transfer Trip (PUTT)
    • Directional Comparison Blocking (DCB)
  • Control Usecases
    • Interlocking
