Commit Control is a core safety mechanism in the Noction Intelligent Routing Platform (IRP). It governs how routing changes are applied by enforcing bandwidth-related limits, ensuring that traffic shifts toward providers remain controlled and predictable. These limits are essential for protecting networks from sudden overloads and unintended traffic spikes.Historically, Commit Control has relied on configured bandwidth assumptions. While this works well under stable conditions, real networks are rarely static. Physical interfaces may fail, bonded links can lose members, and available capacity may be reduced without immediate operational awareness. In such cases, Commit Control may continue to operate correctly from a configuration perspective, while the underlying physical capacity has already changed.

With IRP v4.3, we introduce Interface Monitoring, a feature that allows Commit Control to continuously align its decisions with the actual state and capacity of provider-facing interfaces.

Why Physical Interface Awareness Matters for Commit Control

Commit Control is designed to answer a critical question: Is it safe to commit a routing change that increases traffic toward this provider?
The answer depends not only on policy and configuration, but also on whether the provider connection can physically handle that traffic.

Physical failures are an unavoidable part of Continue reading
