The IESG has received a request from the RTP Media Congestion Avoidance Techniques WG (rmcat) to consider the following document: - 'Shared Bottleneck Detection for Coupled Congestion Control for RTP Media.' <draft-ietf-rmcat-sbd-10.txt> as Experimental RFC 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 2018-03-02. 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 This document describes a mechanism to detect whether end-to-end data flows share a common bottleneck. It relies on summary statistics that are calculated based on continuous measurements and used as input to a grouping algorithm that runs wherever the knowledge is needed. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-rmcat-sbd/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-rmcat-sbd/ballot/ No IPR declarations have been submitted directly on this I-D.
