Hi all, Thanks for feedbacks from Pascal, Dominique, Carles and others. After we (three new authors and I) discussed the solution (original draft is draft-li-native-short-address-00) after communicating with Pascal and Carles, some significant modifications were made.
First of all, the document clarifies that NSA is suitable for Low power and Lossy Networks and every NSA node may be aware of IPv6 address of them. So the NSA technology fall into the scope of 6lo working group. Secondly, in this document, we generalized the address allocation function definition and added description of '4.1 NSA addresses and IPv6 Addresses' and 'Limitation of Number of Children Node'. Those should be sufficient to distinguish the NSA allocation from algorithms like IEEE 802.15.5 and its variants. Thirdly and most importantly, to avoid drawbacks brought by renumbering, we added a new mechanism to avoid the renumbering during the topology change, by adding/updating routing entries along the affected path. The cost is comparable with the local repair of RPL. Routing related procedures is refined according to this design, see Section 5, 6 and 8. We also modify IANA part to apply for new registry and ICMP NSA control message. Considering lacking of large bulk of dispatch type space in page 0&1, we suggest to apply for dispatch type values in Page 10. Please have a look at this document and do not hesitate to reply here if you have comments Best regards, Guangpeng -----Original Message----- From: [email protected] <[email protected]> Sent: Monday, October 18, 2021 9:00 PM To: Zhe Lou <[email protected]>; Liguangpeng (Roc, Network Technology Laboratory) <[email protected]>; Luigi IANNONE <[email protected]>; Peng Liu <[email protected]>; Zhe Lou <[email protected]> Subject: New Version Notification for draft-li-6lo-native-short-address-00.txt A new version of I-D, draft-li-6lo-native-short-address-00.txt has been successfully submitted by Guangpeng Li and posted to the IETF repository. Name: draft-li-6lo-native-short-address Revision: 00 Title: Native Short Addressing for Low power and Lossy Networks Expansion Document date: 2021-10-18 Group: Individual Submission Pages: 21 URL: https://www.ietf.org/archive/id/draft-li-6lo-native-short-address-00.txt Status: https://datatracker.ietf.org/doc/draft-li-6lo-native-short-address/ Htmlized: https://datatracker.ietf.org/doc/html/draft-li-6lo-native-short-address Abstract: This document specifies mechanisms of NSA (Native Short Address) that enables IP packet transmission over links where the transmission of a full length address may not be desirable. This document focuses on carrying IP packets across a LLN (Low power and Lossy Network), in which the nodes' location is fixed and changes in the logical topology are caused only by unstable radio connectivity (not physical mobility). The specifications include NSA allocation, routing mechanisms, header format design including length-variable fields, and IPv6 interconnection support.
