Dear all,
I applied the editorial changes.
1. I deleted the definition of "Reporting Process"
2. I removed/replaced all remaining occurrence of "Reporting Process"
btw, as a consequence, I updated the definitions of "packet
report", "report interpretation", "report stream"
3. I deleted the definition of "Measurement Process"
4. I modified all remaining occurrence of "Measurement Process" by
"Selection Process"
btw, as a consequence, I modified the definitions of "Exporting
Process"
I also modified the different requirements from [PSAMP-FMWK] that I
was quoting in section 6.
As a consequence, [PSAMP-FMWK] will have to be updated accordingly.
Then, the figure becomes.
+---------+ +---------+
Observed |Selection| |Exporting|
Packet--->|Process |----->|Process |--->Collector
Stream +---------+ +---------+
\--Metering-/
\-Process-/
Figure B: PSAMP Processes
Shouldn't it be just
+---------+ +---------+
Observed |Metering | |Exporting|
Packet--->|Process |----->|Process |--->Collector
Stream +---------+ +---------+
?
Personally, this is what I would prefer. It makes more sense.
However, I was perfectly clear on the conclusions from the meeting in
Vancouver (this is reason why I started this thread)
From the meeting minutes at
http://www3.ietf.org/proceedings/05nov/minutes/psamp.txt
Open Issue (not numbered): Terminology Metering Process
(IPFIX) vs.
Measurement Process(PSAMP)
Terminology problem: When psamp started it wasn't clear that ipfix
would be
chosen for export, the architecture is similar but still different.
What IPFIX
calls "metering" is defined as "measurement" in PSAMP terminology.
Juergen: Let's use term "metering" for both. Shall we also drop terms
"selection process" and "reporting process"?
Tanja: Keep selection process as part of metering process (is in line
with
IPFIX, because metering process can contain sampling/filtering). But
selection process should be kept.
Nick: I agree.
Juergen: The changes need to be applied also to the framework draft and
the
packet selection draft that are currently in AD review.
Juergen, I would be perfectly happy to edit the diagram as you draw it.
Regards, Benoit.
The same steps from 1 to 4 will have to be
executed for [PSAMP-FMWK] and [PSAMP-TECH]. Alternatively, you might
copy the new definitions from the next [PSAMP-PROTO] version.
Regards, Benoit.
Dear all,
Do I understand correctly from the meeting minutes (below) that we get
rid of the Reporting Process.

Without objections, I will be removing the concept of Reporting Process
in [PSAMP-PROTO].
Anyway, we don't need it in the protocol.
Regards, Benoit.
Tanja, Nick, and al.
Regarding the "Measurement Process -> Metering Process" issue
discussed during the IETF meeting, I understand that:
- the Measurement Process definition disappears
- we replace all instances of Measurement Process by (IPFIX) Metering
Process
- we keep the Selection Process
I was not too clear about the following point:
- do we keep the Reporting Process?
There is actually no information about it (no such thing such as
Reporting Process ID)
This is just a concept, right?
Regards, Benoit.
