Subject: Re: [pcp] Confirming consensus from WG meetings

Dave, all,

I'd like to second Med's comment. 

I'm too opposed to motion #1 below, especially in light of the need for the THIRD_PARTY option for DS-Lite deployments that will start in a couple of months from now as far as some service providers are concerned. The security concerns that have been raised so far do not apply to DS-Lite scenarios, as reminded by Med below.

I think the -24 is in a sufficiently good shape to be published as is, whereas DS-Lite scenarios remain one of the most straightforward use cases for PCP applicability, and was actually a key driver for the initial base spec effort back in 2010.

Simply ignoring what becomes a fact in the very short term because of security considerations that do not apply to such use case is not a good enough reason for me to defer the standardization of the THIRD PARTY at who-knows-when.

Cheers,

Christian.

Objet : Re: [pcp] Confirming consensus from WG meetings

Dear Dave, all,

I was one of the 2 who objected to remove the THIRD_PARTY Option from the base spec. I maintain my objection because I see THIRD_PARTY as an important feature: allow to instruct mappings for non pcp compliant hosts/applications.   

Adding a normative ref to draft-wasserman for the THIRD_PARTY is too strong IMHO. The major scenarios which driven so far the development of PCP do not require authenticated PCP communications: why doing this for explicit mapping while this is not required for implicit mappings!

I do not want to slow down the progress of PCP base spec but cutting the important features from the base spec won't help too. 

Cheers,
Med
