Intermediate per-flow states are eliminated thanks to source routing. Traffic accounting plays a critical role in network operation and capacity planning. A traffic account solution is required for SR networks that provides the necessary functionality without creating any additional per SR path states in the fabric. This document provides a holistic view of network capacity planning in a SR network and specifies the mechanisms and counters that are required for a SR Traffic Accounting solution.}, }
