All, As mentioned in my previous mail, the authors of the NSA draft consider that the reliability question deserves an in-depth analysis. We submitted an initial draft named "Reliability Considerations of Native Short Addressing" (see below) The document tackles the general problem of reliability in the context of NSA and discusses two approaches that can be used to provide reliability. A first one is based on the use of alternative parents/children keeping using one single address for each NSA node. A second approach basically proposes to build several NSA topologies, each one using different addresses, hence every NSA node uses several addresses. Examples for both approaches are provided as well as a discussion about pros and cons.
We would appreciate any feedback the group can give, on questions like: - Is the draft well organized? - Is there something missing? - What should be done in more details? - Any technical feedback on the single address approach? - Any technical feedback on the multi-address approach?

Name: draft-li-nsa-reliability Revision: 00 Title: Reliability Considerations of Native Short Addressing Document date: 2022-05-31 Group: Individual Submission Pages: 25 URL: https://www.ietf.org/archive/id/draft-li-nsa-reliability-00.txt Status: https://datatracker.ietf.org/doc/draft-li-nsa-reliability/ Htmlized: https://datatracker.ietf.org/doc/html/draft-li-nsa-reliability Abstract: Native Short Address (NSA [I-D.li-6lo-native-short-address]), proposes to algorithmically assign short addresses to nodes in a 6lo environment so to achieve stateless forwarding, hence, avoiding using a routing protocol. NSA is more suitable in case of stable and static wireline connectivity, in order to avoid renumbering due to topology changes. Even in such kind of scenarios, reliability remains an issue. This memo tackles specifically reliability in NSA deployments, analyzing possible broad solution categories to solve the issue.
