Hi Shunwan

Thanks for the review and comment.

We will explore this and update the draft to add higher percentiles in next 
version.
I am more inclined to keep P95 than P99 (which is almost 100%).

Note that maintaining/exporting these multiple percentiles stats might be an 
overhead at router. So we should maintain a balance between overhead and the 
value that it provides.

Thanks
Mukul

Subject: [GROW] Mail regarding draft-ietf-grow-bmp-stats-informational-tlv

Hi Authors and GROW WG,

Thanks for introducing draft-ietf-grow-bmp-stats-informational-tlv-00. Moving 
to a flexible TLV structure for BMP Statistics is a very welcomed step.

I noticed that the draft currently introduces Median (P50) for statistical 
metrics. I would like to suggest exploring the addition of higher percentiles, 
such as P75, P95, or P99.

In operational telemetry (e.g., routing convergence time, processing latency, 
or queueing delays), metrics often exhibit long-tailed distributions. While P50 
provides a useful baseline, tail latencies and transient anomalies are usually 
masked by P50. In practice, operators rely heavily on P95 or P99 to detect SLA 
degradation and bottlenecks.

It would be great to get the authors' and the WG's thoughts on whether 
expanding the scope to cover higher percentiles makes sense for this draft.

Best regards,
Shunwan
