The IESG has approved the following document: - 'Transmission of IPv6 Packets over DECT Ultra Low Energy' (draft-ietf-6lo-dect-ule-09.txt) as Proposed Standard This document is the product of the IPv6 over Networks of Resource-constrained Nodes Working Group. The IESG contact persons are Suresh Krishnan and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-6lo-dect-ule/ Technical Summary The DECT Ultra Low Energy is an addition to the DECT interface primarily intended for low-bandwidth, low-power applications such as sensor devices, smart meters, home automation etc. As the DECT Ultra Low Energy interface inherits many of the capabilities from DECT, it benefits from long range, interference free operation, world wide reserved frequency band, low silicon prices and maturity. There is an added value in the ability to communicate with IPv6 over DECT ULE such as for Internet of Things applications. As an example, the technology could be integrated with residential gateway. DECT-ULE deployment typically use application profile based protocol support and 6lo-over-dect-ule is one of them. The differences between 6loWPAN(IPv6-over-IEEE802.15.4) and this specification are that DECT-ULE only supports Star topology, a 40-bit unique ID among DECT devices, optional MAC-48 bit assignment, larger MTU size than IEEE802.15.4 and thus different requirements for fragmentation and re-assembly. The document also shows a mechansim for deriving the 64-bit IID in order to form an IPv6 address and subsets of RFC6775, Header compression. The draft discusses privacy considerations and possible randomly generated IID support. Working Group Summary The document has been reviewed by several WG participants and the co-chairs. There were no contentious issues raised on the current version. Document Quality The document has been reviewed over the 6lo WG mailing list (Kerry Lynn, Ralph Droms, Samita Chakrabarti, Gabriel Montenegro) and the comments were addressed. A critical comment for the document was to remove reference of globally unique 64-bit IID when it is derived from 40bit DECT unique id, which was taken care in version 05. The chairs have been informed that RTX and Gigaset have implementations on the draft. An open source implementation might be available via ULE alliance.
