[xrblock] ippm metrics registry for xrblock metrics

["Huangyihong (Rachel)" <[e-mail]>]

Hi,

IPPM has the work that defines the Entries for the Performance Metrics Registry (draft-ietf-ippm-metric-registry-13).  The motivation is to have a single point of reference for performance metrics defined in different working groups, and also achieved interoperability. The initial entries for the performance metrics registry (draft-ietf-ippm-initial-registry-05) has a section 12 to show an example that RTCP XR metrics could also be registered into it, but the authors didn't put too energy in this and expect some RTCP XR people could be do this if they think it's useful.

I'm following this work. From my point of view, it's useful as it is allowed for some reporting protocols other than RTCP SR/RR/XR to report these RTP related metrics. But we don't need to registry all the existing XR metrics. Some of them like Loss, Discard, Delay, Burst metrics, defined in RFC3611, 6843, 6958, 7003 may be quite useful and widely used in the industry.

I'm sending this email to ask for WG's opinions. Do you think it is a valuable work, and if it is, do these metrics make sense to you?

BR,
Rachel
