Re: Standards for IP stats collection? (corrected)

["Richard W. Tibbs" <rtibbs@ieee.org>]

I have weighed in with opinions on this subject before, so again --
IP statistics collection can be divided into two areas:
Traffic characteristics, and
Performance characteristics.
The IPPM wg as well as ITU Y.1540/1541 focus almost exclusively on the second
area.
Unless te-wg or ccamp can give greater effort in the first area, there is truly
a hole in the
fabric of traffic engineering, IMHO.
Blaine's draft, which I am contributing to, seems to be a possibile point to
start.
One point I return to (ad nauseum, I know) is the need to understand
traffic characteristics on time scales as small as seconds.
15-minute intervals were fine for best-effort.
Not so fine anymore, I think.
