A new Request for Comments is now available in online RFC libraries. RFC 7509 Title: RTP Control Protocol (RTCP) Extended Report (XR) for Post-Repair Loss Count Metrics Author: R. Huang, V. Singh Status: Standards Track Stream: IETF Date: May 2015 Mailbox: rachel.huang@huawei.com, varun@comnet.tkk.fi Pages: 11 Characters: 23350 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-xrblock-rtcp-xr-post-repair-loss-count-11.txt URL: https://www.rfc-editor.org/info/rfc7509 DOI: http://dx.doi.org/10.17487/RFC7509 This document defines an RTP Control Protocol (RTCP) Extended Report (XR) block that allows reporting of a post-repair loss count metric for a range of RTP applications. In addition, another metric, repaired loss count, is also introduced in this report block for calculating the pre-repair loss count when needed, so that the RTP sender or a third-party entity is able to evaluate the effectiveness of the repair methods used by the system. This document is a product of the Metric Blocks for use with RTCPs Extended Report Framework Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.
