IETF 65 IPFIX CHARTER4 Status of related I-Ds Some of the drafts are quiet mature  already discussed at two IETF/PSAMP sessions  there seems to be consensus that this work is useful  there seems to be consensus that the chosen approach is the right one  the documents are quite complete Some drafts need more work For some the basic approach still needs to be agreed on For some even the need is not clear

IETF 65 IPFIX CHARTER5 How could a home for this work look like? Change of WG charter layout  from single long-term big target  to a sequence of short-term smaller targets Select out of the list of suggested work items  those with agreed relevance and approach  those that are rather mature Define a short-lived charter focused on completing these work items  less than a year Still continue discussion of other work items  on mailing list, presentations at sessions  further develop them as individual submissions When (most of) the charter’s items are completed:  either select new ones that have matured meanwhile  or shut down the WG

IETF 65 IPFIX CHARTER6 How to select work items? Is the problem clear and well understood? Is the work relevant?  Do we need it? Do we need it now? Is the approach clear and agreed? Is the approach well understood? Does it need modifications of the IPFIX protocol?  We should avoid this. What is the quality of current individual drafts? How long will it take us to complete?
