Hi Emile,

Thanks for this message. I have gone through this thread and the existing
MIBs. I have listed my comments/observations below:

1. In general, we do not include "STD" for a draft MIB. Only
when they are about to become RFC, we call them STD.

Before becoming an RFC we have "DRAFT" for the MIBs.
This way if some companies want to implement the draft versions
and later want to upgrade to standard versions do not have a name
clash with the OIDs.


2. I agree with most of your decomposition.
However, I want to propose :
PCEP-DRAFT-MIB         draft-ietf-pcep-mib

instead of
PCE-COMP-STD-MIB         draft-ietf-pce-comp-mib

This will give a clear idea to the user on what the MIB contains.

So the new decomposition looks like:
MIB module               WG draft name
================================================
PCE-DISC-DRAFT-MIB         draft-ietf-pce-disc-mib
 -- PCE discovery MIB.

PCEP-DRAFT-MIB         draft-ietf-pcep-mib
 -- PCE communication protocol MIB

PCE-PCC-DRAFT-MIB          draft-ietf-pce-pcc-mib
 -- Path Computation Client MIB

PCE-TC-DRAFT-MIB           draft-ietf-pce-tc-mib
 -- PCE Textual conventions MIB.

3. I see that the SMIv2 structures of the existing MIB modules
need to be fixed and SMIC utility must be run. I can take care of that.

4. I will also start working on the PCEP-MIB for which you will
be my co-author.

Please let me know if you have any more comments/observations? I
intend to start working on these soon.

Regards,
Kiran.

Hi Kiran, Adrian and JP


I am really happy that Kiran join us. I am sure that we are going to do 
excellent works together... and that there is enough work for 2 people.

So let's start.

In July we identify the following MIB modules decomposition.

MIB module               WG draft name
================================================
PCE-DISC-STD-MIB         draft-ietf-pce-disc-mib
PCE-COMP-STD-MIB         draft-ietf-pce-comp-mib
PCE-PCC-STD-MIB          draft-ietf-pce-pcc-mib
PCE-TC-STD-MIB           draft-ietf-pce-tc-mib

draft-ietf-pce-disc-mib and draft-ietf-pce-tc-mib are already in progress.

As JP spoke recently of a "PCEP MIB", I want to be sure that we still agree on 
this decomposition?

Then I propose to draft the abstract of each document conjointly with the 
chairs.

Finally, I think that we may identify the drafts and the sections giving 
directions to write each MIB module.

At this point, each of us will share the minimal understanding before writing 
any SMI line.

Regards
Emile

Hi Adrian,

I think we got it:

MIB module               WG draft name
================================================
PCE-DISC-STD-MIB         draft-ietf-pce-disc-mib
PCE-COMP-STD-MIB         draft-ietf-pce-comp-mib
PCE-PCC-STD-MIB          draft-ietf-pce-pcc-mib
PCE-TC-STD-MIB           draft-ietf-pce-tc-mib


According to that I will firstly review and rename my current draft as
draft-stephan-pce-disc-mib-00.txt. Then I will create
draft-stephan-pce-tc-mib-00.txt. Finally I will post both of them.

Regards
Emile
