All,

Ole's agenda is a big improvement, as in it addresses the concerns I (and
others voiced) in the past weeks. That said, to make the proceedings follow
a more structured  Introduction; Requirements; Details, sequence, I would
like to propose the following (changes in the order of things proposed by
Ole):

1. Intro, logistics, chairs

2. Stateless IPv4 address sharing overview and requirements

 2.1 General
 - Satoru:
http://tools.ietf.org/html/draft-ietf-softwire-stateless-4v6-motivation-00
 - Wojciech: http://tools.ietf.org/html/draft-dec-stateless-4v6-03
 - Xiaohong:
http://tools.ietf.org/html/draft-boucadair-softwire-stateless-requirements-00

2.2 Operator's perspectives
 - Satoru: An operator's view, address mapping in particular with our cases
 - Xing: The operational requiements and the experience of the single and
dual
 stateless translation concerning CERNET (IPv4) and CNGI-CERNET2 (IPv6).
- ChongfengXie ChinaTelecom
- Hui Deng: Operator's Comparision between encapsulation and translation

3. Stateless solutions and mechanisms

  3.1. dIVI
 - Xing: https://datatracker.ietf.org/doc/draft-xli-behave-divi-pd
 - Xing: https://datatracker.ietf.org/doc/draft-xli-behave-divi

  3.2. 4rd
 - Tetsuya: http://tools.ietf.org/html/draft-murakami-softwire-4rd-00

  3.3 SMAP
 - Xiaohong:
http://tools.ietf.org/html/draft-boucadair-behave-ipv6-portrange-04
 - Xiaohong:
http://tools.ietf.org/html/draft-deng-v6ops-aplusp-experiment-results-01

3.4 SA46T-AS
 - Naoki: http://tools.ietf.org/html/draft-matsuhira-sa46t-as-00

4 Summary:
  - Ole Troan: Comparision between encapsulation and translation
 - All: Day 1 summary & initial conclusions

Tuesday:

 5.1. Stateless address mapping algorithms
 - Ole port algorithm requirements, selection criteria
 - Remi:
http://tools.ietf.org/html/draft-despres-softwire-stateless-analysis-tool-00
 - Xiaohong:
http://tools.ietf.org/html/draft-bsd-softwire-stateless-port-index-analysis-00
-  Jacni Qin:
http://tools.ietf.org/html/draft-despres-softwire-4rd-addmapping-00

5.2. DS-lite enhancements (4over6, NAT bypass...)

6. Day 2 & Meeting Conclusions

Regards,
Woj.
