Introduction "Static Context Header Compression (SCHC) and fragmentation for LPWAN, application to UDP/IPv6" [SCHC] defines a generic compression and fragmentation protocol that is optimized for LPWAN networks. SCHC needs to be instanciated to be applied to a particular networking technology. This is being done at the LPWAN WG for [LoRaWAN], [Sigfox], and [NB-IOT]. SCHC does not have to be limited to compression and fragmentation; it can be extended for other purposes, e.g., to transport commands and responses. The necessary commands appear to be very similar across technologies and it makes sense to create a shared IANA registry that is valid across technologies. 2. Terminology 2.1. References 2.2. BCP 14 The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119][RFC8174] when, and only when, they appear in all capitals, as shown here. 3. Purpose of this document This document creates a registry for command and control rule values across technologies. This does not mean that all technologies need to implement all the command and controls defined in the IANA registry that this document creates, either. Thubert Expires 26 September 2020 [Page 2] Internet-Draft SCHC commands March 2020 4. Security Considerations This specification only creates a registry. There is no security consideration about the registry itself. 5. IANA Considerations This specification creates a new Subregistry for the LPWAN command and control values for use within the [SCHC] protocol. * Possible values are 8-bit unsigned integers (0..255). * Registration procedure is "Standards Action" [RFC8126]. * Initial allocation is as indicated in Table 1: +-------+---------+-----------+ | Value | Meaning | Reference | +=======+=========+===========+ | 0 | Reset | RFC THIS | +-------+---------+-----------+ | 1 | Ack | RFC THIS | +-------+---------+-----------+ | 2 | Rekey | RFC THIS | +-------+---------+-----------+ Table 1: Acceptance values of the RPL Status 6.
