  MVPS / Coherence-BFD vs. 10 Mpps volumetric DDoS
  Simulation date: 2026-05-22 01:35:32
================================================================

TOPOLOGY
  Vantages                   10,000
  Regions                    8
  Vantages per region        1,250
  Coherence dim (d)          6
  Control tick (T_tick)      50 ms
  M-multiplier               3
  Alarm threshold (D²)       30.0

ATTACK
  Type                       Volumetric DDoS
  Rate                       10,000,000 pps  (10 Mpps)
  Target                     Region 3 (1,250 vantages)
  Duration                   ticks 200..480
                             = 14.0 s

CONTROL PLANE LOAD (telemetry, not attack)
  Telemetry PPS              200,000 pps
  Packet size                116 bytes
  Aggregate bandwidth        23.20 MB/s
  Regime classification      C  (manual IRQ pinning required, per §15.3)
  Broker availability (min)  99.0 %
  Broker status seen         ['REGIME_C_TUNED']

DETECTION OUTCOME
  Detection latency          100 ms (after attack onset)
  Lower bound (M·T_tick)     150 ms
  Achieved / bound ratio     0.67x

ATTRIBUTION (R_cross)
  Argmax-region accuracy     100.0 %
  Wrong-region windows       0 / 275
  Conclusion                 Attack geographically localised to region 3.

CONCLUSION
  1. Broker does NOT die from DDoS — telemetry plane is separate.
  2. Broker survives its OWN legitimate load (200 kpps) under Regime C tuning.
  3. DDoS deforms coherence surface in 100 ms.
  4. R_cross localises the attack to its source region with 100% accuracy.
  5. MVPS is a DDoS detector, not a DDoS victim, when control plane is
     properly segmented (out-of-band management network).

WHEN MVPS *WOULD* BE AT RISK
  - If broker and vantages share the same NIC as user traffic (bad design)
  - If telemetry runs over the same VLAN as the data plane (bad design)
  - If broker is in Regime D (>1 Mpps telemetry) without DPDK/AF_XDP
  - If attacker compromises >3 of the 8 cells (Byzantine breakdown,
    Theorem 7: breakdown bound = floor((k-1)/2) = 3)
