Dear WG members, I didn't had time to read the last version of 4rd-U but I read carefully -03 when it was published.
I really appreciated the work done by Rémi to write down -03. The document is well written, easy to read and the requirements are clearly sketched. I really think this spirit should be adopted by MAP documents. As I already told Rémi, I would like if all proponents of stateless A+P converge and avoid wasting energies in comparing individual proposals. I thought this is what has been agreed during the softwire interim meeting: IMO, MAP effort meets the objective of group work. Some of the points raised by Rémi can be easily considered in the context of MAP; except the idea of unified header which is a step forward. Adopt a unified approach is exclusive to encapsulation and/or translation. The question now is: Does the unified approach bring new features + simplification compared to the normal IPv4-in-IPv6 encapsulation scheme (which I'm mainly interested in)? The answer is: No. Perhaps this is selfish but given what I mentioned above, I vote for the following: * Adopt the work of the MAP design team as the base specification for stateless A+P effort. * Make sure proposals from Rémi (except U) are discussed: e.g., Checksum neutrality (1) Share the archives of MAP Design Team discussion (2) Use IETF Issue Tracker to record the issues and the consensus/conclusion (3) Adopt a clear procedure within the Design Team to make decisions when there are conflicts * Reduce the amount of MAP documents: IMHO, three documents are needed (1) MAP Address Format (2) MAP Overall Architecture and Design Recommendations (3) MAP DHCPv6 Options Cheers, Med >-----Message d'origine----- >De : softwires-boun...@ietf.org >[mailto:softwires-boun...@ietf.org] De la part de Alain Durand >Envoyé : mardi 20 mars 2012 00:39 >À : Softwires WG >Cc : Yong Cui; Ralph Droms >Objet : [Softwires] Path to move forward with 4rd. > >Dear wg, > >After a number of discussions with my co-chair, our AD and >various authors, here is how we would like to move forward wrt 4rd. > >1) There is an observation that all the solutions on the >table E, T & U actually solve the stateless problem we started with. > There are differences, but it is unclear if those >differences are really significant.
