Abstract
Time-travel replay tokens using consistent cross-domain snapshots provide a control-plane system and technique for making multi-domain network changes repeatable. The system captures a consistent snapshot boundary across participating controllers and mints a signed token that binds an intent to the previews, rollback handles, and state references used to plan the change. Before execution, each domain must prove that the domain still conforms to the token boundary. If any required domain has drifted, the token is rejected and the system re-snapshots and re-plans instead of applying a stale decision. As a differentiator from ordinary snapshots, rollback, or audit logging, the token acts as an execution license and replay key rather than merely as a record, allowing the same decision context to be reconstructed for deterministic replay, audit, and rollback across campus, wide area network (WAN), data center (DC), and service provider domains. The technique makes artificial intelligence (AI)- or intent-driven network actions safer and more traceable by distinguishing a changed network state from changed decision logic.
