The question should be:

	Should IETF work on a new solution for a market where a solution exists and the existing solution is equal or superior to the newly proposed one?

Argument for statement "the existing solution is equal or superior to the newly proposed one" is:
- the existing 3GPP solution is already developed, tested, mass produced and mass deployed and thus benefits from economies of scale.
- no existing 3GPP requirement was identified as unnecessary for the new solution so complexity of the existing solution and new solution is the same.

If you believe that statement "the existing solution is equal or superior to the newly proposed one" is incorrect, please prove it.

Kind regards

Ivo Sedlacek

Hi Keith,

are you suggesting that IETF processes shall only allow work on technologies for which there is a known market?

I'm glad this was not the case in the past, otherwise I would not be able to send a single email. At least I don't have memory of IETF business case criteria for the SNMP protocol. If that shall change in the future, I would like to know what is the specific IETF criteria for market existence. Can you elaborate what these are supposed to be?

p.s. one more question here: I understand your point that I'm eligible to read emails to this WG mailing list that carry confidentiality notice on the grounds of group memership. What I don't understand is whether I'm also permitted (in departure from the notice) to forward such an email to some other email address than that of the working group.
