Rule-based Routing(RBR)
A deterministic routing system that uses predefined rules, conditions, and decision trees to direct queries to appropriate handlers, providing fast, predictable, and auditable routing decisions through if-else statements, switch cases, and pattern matching ideal for compliance-critical and latency-sensitive agentic AI systems
In 30 seconds
- What
- Uses if-else logic and pattern matching to deterministically route queries to handlers based on predefined rule conditions.
- When to use
- Compliance-critical systems, latency-sensitive routing, or workflows where audit trails and predictability matter more than flexibility.
- Watch out
- Rules become brittle and unmaintainable as edge cases accumulate; new query types often fall through or match wrong rules.

Rule-based Routing: Overview
A deterministic routing system that uses predefined rules, conditions, and decision trees to direct queries to appropriate handlers, providing fast, predictable, and auditable routing decisions through if-else statements, switch cases, and pattern matching ideal for compliance-critical and latency-sensitive agentic AI systems
- Deterministic if-else and switch case logic
- Pattern matching with regex and keywords
- Rule precedence and conflict resolution
- Configuration-driven rule management
- Ultra-low latency routing decisions (<5ms)
- Complete audit trail and traceability
- Version control for rule definitions
- Hybrid integration with AI fallbacks
