Are these app designers clairvoyant? If not, how can they "know the range of delay variation they must accommodate, whether they are designing fixed or adaptive buffer systems" from measurements that can't be made until the system is not only implemented but deployed (at least in a test bed)? The next sentence doesn't make much sense, either, as written. I suggest deleting the first and rewriting the second to make more sense; for example: "For example, network managers can use this metric to compare actual delay variation to targets (i.e., a numerical objective or Service Level Agreement) to help ensure the quality of real-time application performance." Or something like that. What does Section 2 mean? How can one use an entire RFC as a "terminology statement"? Does it actually mean "This document uses ABNF notation [RFC5234] in Section 4."? If so, just say that; OTOH, since the ABNF usage is in the context of SDP & RFC 3611 both references the ABNF spec and is listed as a normative reference in this draft, why bother? I suggest just deleting Section 2. > > -----Original Message----- > From:xrblock-bounces@ietf.org [mailto:xrblock-bounces@ietf.org] On > Behalf Ofinternet-drafts@ietf.org > Sent: Friday, September 14, 2012 12:26 PM > To:i-d-announce@ietf.org > Cc:xrblock@ietf.org > Subject: [xrblock] I-D Action: draft-ietf-xrblock-rtcp-xr-pdv-06.txt > > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > This draft is a work item of the Metric Blocks for use with RTCP's > Extended Report Framework Working Group of the IETF. > > Title : RTCP XR Report Block for Packet Delay > Variation Metric Reporting > Author(s) : Alan Clark > Qin Wu > Filename : draft-ietf-xrblock-rtcp-xr-pdv-06.txt > Pages : 21 > Date : 2012-09-14 > > Abstract: > This document defines a Real-Time Control Protocol (RTCP) Extended > Report (XR) block that allows the reporting of Packet Delay Variation > metrics for a range of Real-time Transport Protocol (RTP) > applications. > > > The IETF datatracker status page for this draft is: > https://datatracker.ietf.org/doc/draft-ietf-xrblock-rtcp-xr-pdv > > There's also a htmlized version available at: > http://tools.ietf.org/html/draft-ietf-xrblock-rtcp-xr-pdv-06 > > A diff from the previous version is available at: > http://www.ietf.org/rfcdiff?url2=draft-ietf-xrblock-rtcp-xr-pdv-06 > > > Internet-Drafts are also available by anonymous FTP at: > ftp://ftp.ietf.org/internet-drafts/ > > _______________________________________________ > xrblock mailing list > xrblock@ietf.org > https://www.ietf.org/mailman/listinfo/xrblock > _______________________________________________ > xrblock mailing list > xrblock@ietf.org > https://www.ietf.org/mailman/listinfo/xrblock
