8th March 2018

Dear BoF Chairs,


Re: Agenda revisited - COMS BoF at IETF101 (i.e. Thursday 22nd March 2018; Balmoral room)



Thank you for your message of 7th March 2018 and initial draft agenda for COMS BoF at IETF101. 

In parallel the BoF proponents have worked on the agenda based on the 3 questions from the AD and 5 objectives from the BoF Chairs.

These questions/objectives are:

AD’s (Benoit’s) questions to be addressed in the COMS BoF (message of 9th February 2018)
- (Q1) clarify the problem space (i.e. proponents interpretation : why, what, when, how, priorities)
- (Q2) find out whether IETF is the right place for this type of top down approach
- (Q3) how would that top down approach meet bottom up (being worked on in different WGs) 
COMS BoF Chairs (Gonzalo and Adrian) objectives to be addressed in the COMS BoF (message of 26th February 2018) 
- (O4) What is the problem space? This is not just what is in scope, but also what is out of scope.
- (O5) In particular, it is the focus of the problem: *the* thing that you want to achieve in an operational network.
- (O6) What is your proposed solution architecture?
- (O7) What interfaces (precisely!) are you proposing should be worked on?
- (O8) What deliverables do you envision and (since no one can have everything they want immediately) how would you prioritize the deliverables and where would you draw the line between "must have" and "can live without for now”?

Please find enclosed revised draft agenda as proposed by the BoF proponents,  which is integrated with your proposal as follows:
