Re: [xrblock] Burst Discard Count

The argument is correct, but when the burst count for loss and burst count for discard are corresponding to the same reported source, the value for them are probably same.
Also burst gap discard is intended to be sent together with burst gap loss.
See the section 1 of RFC7003:
"
This block is intended to be used in conjunction with [RFC7002], which provides the
total packets discarded and on which this block therefore depends.
However, the metric in [RFC7002] may be used independently of the
metrics in this block.

Hi all,

While preparing the -01 version of the
draft-ietf-xrblock-rtcweb-rtcp-xr-metrics, I noticed that the
RFC6958 - Burst/Gap Loss reports a "burst count" metric, which indicates the number of bursts  in an reporting interval (cumulative or arbitrary time interval). However, RFC7003 does not report a corresponding burst count metric for discarded packets.

I forget if this was discussed before, but it appears to be an oversight, as arguments for including burst count for loss also apply to burst discards -- unless I am missing something or it is defined elsewhere. How do we fix this?

This may be non-blocking for the rtcweb metrics as we could instead use the burstLossRate and burstDiscardRate which are defined in the summary statistics in RFC7004.

Thanks and Regards,
Varun
