Dear all,

I posted a new version of the IPFIX protocol draft.
Here are the changes in the new draft version.

_Closed Issues_

PROTO-3: IP encapsulated packet.

PROTO-5, 6, 7, 8, 9, 10, 11: SCTP and SCTP-PR
Resolution:
    - modified section 5.1 "Transport Compliance and Transport Usage", 
SCTP PR is a MUST
    - new section 5.3

PROTO-5, 6, 7, 8, 9, 10, 11: UDP
Resolution:
    - New section 5.4

PROTO-12: Do we need the IETF exclusive template flowset format.
Issue closed.
Resolution:
    - remove section 8.3.1 IETF Exclusive Template FlowSet Format
    - remove section 8.5.1 IETF Exclusive Options Template FlowSet Format
    - remove the notion of the Vendor Specific (option) template: only 
keep (option) template

PROTO-13: How to distinguish IETF field IDs from vendor field IDs
Resolution:
    - new section 8.2

PROTO-14: Why do we need padding? Should we shift it to MAY?
    limit the size of the padding? Yes
Resolution:
    New text inserted for all the new FlowSet

PROTO-15:   Remove Reserved 2 octets in Vendor specific option template 
flowset and add padding at the end

PROTO-22: Exporter ID (ie IP address of exporter)
Resolution
    - The next version of the IFPIX information model will contain an 
Exporter ID data type.
    - nothing changed to the IPFIX protocol spec.

PROTO-28: Packet Sampling.
Resolution:
    New sentence in section 2.1 IPFIX Documents overview:
   " The IPFIX protocol supports packet sampling. The methods of 
metering packet samples are out of  scope of this specification."

PROTO-30: sections and subsections alignments are wrong

_Others changes:_
- New issue PROTO-29: The insertion of the new transport protocol 
sections has highlighted some inconsistency in the section 13  (template 
management) and the section 14 (The Collecting Process's Side).
- Minor editorial changes
- Section 16.4, correction of the example: both field length were 4 ->  
it was a mistake, they should be 2.
- PROTO-27 "Need an example with the Vendor Specified Information 
Element" changed to PROTO-27 "Correct the examples: no more FlowSet 0 and 1"
- changed the point 3 of the section 12 "Template Management"

As usual, the first section of the draft contains the updated lists of 
issues and action items.

Regards, Benoit.
