Advanced Unidirectional Route Assessment
RFC 9198, “Advanced Unidirectional Route Assessment”, is a Proposed Standard document published in May 2022 by J. Alvarez-Hamelin, A. Morton, J. Fabini, C. Pignataro, R. Geib. It updates RFC 2330. The canonical text is published by the RFC Editor.
Abstract
This memo introduces an advanced unidirectional route assessment (AURA) metric and associated measurement methodology based on the IP Performance Metrics (IPPM) framework (RFC 2330). This memo updates RFC 2330 in the areas of path-related terminology and path description, primarily to include the possibility of parallel subpaths between a given Source and Destination pair, owing to the presence of multipath technologies.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
