One small technical comment on this sentence: Sec 2.3: "Per-stream QoS can be provided by a combination of packet marking and end-to-end agreements." If this sentence is meant to mean use of DSCP, I don't think this is true, as DSCP is usually not available end-to-end but most often gets changed or bleached somewhere on the path. And two editorial comments: Sec 2.1: "The SNI was defined to facilitate management of servers, though the developers of middleboxes soon found out that they could take advantage of the information." "soon found out" does sound a bit story-telling like to me. I recommend a more objective phrasing like: "The SNI was defined to facilitate management of servers, though other usages by middleboxes also take advantage of the information." or something similar... Also sec 2.1: "The SNI is probably also included in the general collection of metadata by pervasive surveillance actors." This sentence is phrased a bit speculatively and at the same kind seems inherently true as a "pervasive surveillance actor" usually just collect all available data/traffic... I guess the more interesting question would be if and how this information is used. Anyway I recommend some rephrasing like: "The SNI could also be utilised by the general collection of metadata by pervasive surveillance actors." _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
