Goal-Driven Optical & IP Backbone
Five-nines transport, held as a goal — optical and IP correlated as one
CraftWorld Transport is the carrier-grade assurance and autonomy platform for the optical and IP backbone. It unifies the full transport stack — from raw photonics through DWDM, OTN, and IP/MPLS to BGP — under a single control plane, correlating physical-layer events with their routing impact so a fault and its downstream consequence resolve to one root cause. Operators declare the backbone goals they own — availability, latency, protection, and capacity headroom — and the Ritam AIOps engine holds them true: predicting degradation before a span drops, pre-positioning traffic, and re-routing on approval. The platform is multi-vendor by design and runs in production at Tier-1 scale.
Platform Overview
| Domain | Carrier transport backbone — DWDM/OTN optical, IP/MPLS, BGP |
| Control model | Declare backbone goals (availability, latency SLA, protection, capacity) → Ritam measures & holds them |
| Autonomy posture | Agentic-with-approval — pre-planned protection re-routes execute autonomously to hold SLA; capacity and topology change is proposed, dry-run, and approved |
| Positioning | Correlates optical and IP as one backbone — a physical event and its routing impact are one story, not two tickets |
| Delivery | SaaS or operator-cloud · augments incumbent NMS |
The Transport Stack — Layer by Layer
CraftWorld manages five transport layers, each monitored to KPI level and held to a declared SLA:
- Photonic Layer — per-channel optical signal quality, amplifier health, span loss; degradation caught before the network layer sees a fault
- DWDM Layer — per-wavelength health, path re-routing to protected capacity, channel power balance
- OTN Layer — trail continuity and protection-switch validation, held to ≥ 99.999% trail availability
- IP / MPLS Layer — path continuity, bandwidth reservation, backup-path validation, capacity headroom management
- BGP Layer — peer/session state, route-leak and hijack detection, convergence assurance
Autonomous Capabilities
Predictive optical protection — the platform learns each span's optical fingerprint and detects a degradation trend 45–90 minutes before a fault occurs — pre-positioning traffic on a protected path so the availability goal never dips.
BGP hijack / route-leak containment — a genuine hijack is distinguished from a legitimate configuration change in real time, and the anomalous route is filtered in under three minutes.
Cross-layer root cause — photonic, transport, IP, and routing telemetry are bound into a single causal graph; an optical fade and a routing flap on the same physical path resolve to one root cause in under 60 seconds — not two unrelated tickets.
Capacity forecasting — per-span and per-trunk capacity exhaustion is forecast well ahead of time, turning capacity planning from a reactive scramble into a planned cycle.
Telemetry & Execution
Every automated action — path re-routes, protected-capacity switches, route filters — is dry-run, approval-gated, audited, and reversible.
