[xrblock] Burst Discard Count

[Varun Singh <[e-mail]>]

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
