The IESG has received a request from the TURN Revised and Modernized WG (tram) to consider the following document: - 'Discovery of path characteristics using STUN' <draft-ietf-tram-stun-path-data-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-02-11. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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 discover the path characteristics using Session Traversal Utilities for NAT (STUN) messages. The measurement information can then be used to influence the endpoint's Interactive Connectivity Establishment (ICE) candidate pair selection algorithm. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-tram-stun-path-data/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-tram-stun-path-data/ballot/ No IPR declarations have been submitted directly on this I-D.
