A Routing Framework is a structured system for directing queries, requests, or data to the most appropriate handler, model, or processing pipeline based on defined rules, learned policies, or contextual signals. In AI and network systems, routing frameworks govern how inputs are dispatched across components such as specialized models, retrieval systems, or compute nodes. They are applied in retrieval-augmented generation, mixture-of-experts architectures, and multi-agent systems to improve efficiency, accuracy, and resource utilization.
