A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-xrblock-rtcp-xr-qoe/ Technical Summary This document defines an RTP Control Protocol (RTCP) Extended Report (XR) Block including two new segment types and associated SDP parameters that allow the reporting of MOS Metrics for use in a range of RTP applications. Working Group Summary The WG reviewed carefully the document several times and there is good support behind it. Document Quality Two vendors indicated that they have similar functionality in their code and intentions to implement the standard block when approved. There was one important change to notice which resulted from the SDP Expert Review which led to the change of the title of the document from QoE to MOS Metric reporting, which defines better the scope of the document.
