Toutain, C. Gomez, D. Barthel, JC. Zúñiga Status: Standards Track Stream: IETF Date: April 2020 Mailbox: ana@ackl.io, laurent.toutain@imt-atlantique.fr, carlesgo@entel.upc.edu, dominique.barthel@orange.com, juancarlos.zuniga@sigfox.com Pages: 71 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-lpwan-ipv6-static-context-hc-24.txt URL: https://www.rfc-editor.org/info/rfc8724 DOI: 10.17487/RFC8724 This document defines the Static Context Header Compression and fragmentation (SCHC) framework, which provides both a header compression mechanism and an optional fragmentation mechanism. SCHC has been designed with Low-Power Wide Area Networks (LPWANs) in mind. SCHC compression is based on a common static context stored both in the LPWAN device and in the network infrastructure side. This document defines a generic header compression mechanism and its application to compress IPv6/UDP headers. This document also specifies an optional fragmentation and reassembly mechanism. It can be used to support the IPv6 MTU requirement over the LPWAN technologies. Fragmentation is needed for IPv6 datagrams that, after SCHC compression or when such compression was not possible, still exceed the Layer 2 maximum payload size. The SCHC header compression and fragmentation mechanisms are independent of the specific LPWAN technology over which they are used. This document defines generic functionalities and offers flexibility with regard to parameter settings and mechanism choices. This document standardizes the exchange over the LPWAN between two SCHC entities. Settings and choices specific to a technology or a product are expected to be grouped into profiles, which are specified in other documents. Data models for the context and profiles are out of scope. This document is a product of the IPv6 over Low Power Wide-Area Networks Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
