Alexandre, Isabelle, and I have just posted a draft on a protocol-independent method for endpoints to signal packet loss to the path, while maintaining end user privacy and resisting ossification. This method can work for any protocol, but the primary focus is, of course, on protocols that encrypt their headers. We think this loss signaling scheme (just takes 2 bits somewhere that are set by the sender) is an appropriate solution for allowing networks to do their job at providing high QoS and ease of troubleshooting without compromising on encrypted protocol goals. - Igor P.S. We've implemented this proposal in some Akamai servers and have been using it to serve actual end-user traffic for a subset of Orange customers. Orange has implemented passive observer that used this signal to detect and identify loss. We will discuss and analyze the data we collected at maprg (while the signaling protocol details belong to tsvwg). ----------------------------------------------------------------------------------------------------------------------------------------------- A new version of I-D, draft-ferrieuxhamchaoui-tsvwg-lossbits-00.txt has been successfully submitted by Igor Lubashev and posted to the IETF repository. Name: draft-ferrieuxhamchaoui-tsvwg-lossbits Revision: 00 Title: Packet Loss Signaling for Encrypted Protocols Document date: 2019-07-08 Group: Individual Submission Pages: 9 URL: https://www.ietf.org/internet-drafts/draft-ferrieuxhamchaoui-tsvwg-lossbits-00.txt Status: https://datatracker.ietf.org/doc/draft-ferrieuxhamchaoui-tsvwg-lossbits/ Htmlized: https://tools.ietf.org/html/draft-ferrieuxhamchaoui-tsvwg-lossbits-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-ferrieuxhamchaoui-tsvwg-lossbits Abstract: This document describes a protocol-independent method that employs two bits to allow endpoints to signal packet loss in a way that can be used by network devices to measure and locate the source of the loss. The signaling method applies to all protocols with a protocol- specific way to identify packet loss. The method is especially valuable when applied to protocols that encrypt transport header and do not allow an alternative method for loss detection.
