Martinsen, T. Reddy, D. Wing, V. Singh Status: Standards Track Stream: IETF Date: September 2016 Mailbox: palmarti@cisco.com, tireddy@cisco.com, dwing-ietf@fuggles.com, varun@callstats.io Pages: 10 Characters: 19893 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-tram-stun-path-data-05.txt URL: https://www.rfc-editor.org/info/rfc7982 DOI: http://dx.doi.org/10.17487/RFC7982 A host with multiple interfaces needs to choose the best interface for communication. Oftentimes, this decision is based on a static configuration and does not consider the path characteristics, which may affect the user experience. This document describes a mechanism for an endpoint to measure the path characteristics fractional loss and RTT using Session Traversal Utilities for NAT (STUN) messages.
