| Internet-Draft | Mechanical Displacement for GREEN | April 2026 |
| Moore & Kinsler | Expires 12 October 2026 | [Page] |
The evolving draft-ietf-green-framework provides necessary YANG data models for monitoring Device Level Energy Efficiency (DLEE) and Component Level Energy Efficiency (CLEE). However, mitigating high-volume East-West traffic (e.g., massive inference synchronization) during peak grid carbon-intensity remains a structural challenge.¶
This document proposes an architectural extension utilizing Delay-Tolerant Networking (DTN). It introduces "Mechanical Displacement"—the physical routing of encrypted cold data via autonomous or commercial logistics—as a zero-marginal-emission routing path, managed by hardware-rooted out-of-band blind packet switching.¶

As hyperscale compute environments push unprecedented power densities, systems operating with unmitigated execution authority generate massive data payloads (e.g., AI model weight updates, cold-storage mirroring). While the GREEN framework effectively monitors network energy consumption, rerouting petabyte-scale traffic across alternate digital fiber paths still incurs a massive continuous energy cost.¶
This draft extends the GREEN framework by defining how physical transport logistics can be structurally integrated as high-latency, zero-marginal-emission network nodes, physically offloading digital traffic from carbon-heavy grids.¶
Currently, when GREEN YANG models detect high carbon intensity on a route, the network attempts to throttle or redirect traffic. For delay-tolerant, high-volume data, this still results in significant energy expenditure over extended transmission windows. The framework lacks a mechanism to drop digital transmission energy to absolute zero while maintaining cryptographically secure data transport.¶
The proposed solution integrates the Vettic Currier Network (VCN) as a delay-tolerant routing layer directly responsive to GREEN metrics.¶
Sentry Nodes operate at the silicon level, utilizing blind packet switching to identify the volume and urgency of a payload. Critical telemetry (e.g., execution tokens, failsafe commands) is prioritized for immediate digital backhaul, while massive "cold" data is flagged for potential physical displacement.¶
The routing logic ingests real-time YANG energy metrics (e.g., ietf-power-management) from the GREEN framework. The Sentry Node evaluates the data weight against the local grid's current carbon intensity and power stress.¶
If a high-volume payload encounters a high-stress grid threshold, the VCN triggers the physical routing path. The payload is spool-written to encrypted, localized storage mediums and handed to the courier layer (Mechanical Displacement). By treating autonomous vehicles or commercial logistics as network nodes, the digital grid's power constraints are structurally mitigated.¶
Because this routing architecture shifts data outside traditional digital perimeters, it requires a hardware-rooted Failsafe. The Sentry Node serves as this Executive Anchor. If an unauthorized state divergence or tamper attempt is detected during the offload process, the Sentry Node deterministically drops voltage to zero (V=0) exclusively to the compromised interface, physically severing the connection before data exfiltration can occur.¶
Mechanical Displacement introduces physical custody vectors. To mitigate this, the VCN architecture ensures the physical courier acts purely as a "blind relay." The courier transports the encrypted spool but lacks the cryptographic keys required for decryption or inspection. Data sovereignty is maintained via hardware-enforced encryption, and physical tampering triggers a verifiable failure state sealed in an air-gapped ledger.¶
To secure data in transit via Mechanical Displacement, the VCN enforces Temporal Data Sovereignty. Encrypted data bundles contain an unencrypted header defining strict expiration criteria (e.g., time-to-live thresholds, transit duration limits). If the physical courier fails to reach the destination network within the defined window, a digital fuse logic permanently purges the payload, structurally mitigating data capture if an asset is intercepted.¶
When the Executive Anchor initiates a V=0 severance, it manages residual data at rest. Prior to total power loss, the Sentry Node utilizes blind packet switching to extract critical operational payloads laterally via the VCN, preserving mission continuity. Concurrently, the architecture executes an Active Physical Entropy Flush. It injects a localized voltage spike into the compromised asset's volatile memory (VRAM), obliterating localized data to defend against post-mortem physical extraction attacks.¶
