Tuto-04: SCHC A new era for IoT interoperability


SCHC (Static Context Header Compression and fragmentation) is an international standard produced by the Internet Engineering Task Force (IETF) [RFC8376, RFC8724, RFC8824, RFC9011]. The SCHC standard allows constrained IoT devices to join the Internet ecosystem, accelerating their integration into information systems. The impact of SCHC is constantly growing with great interest both from industrial and academic societies. SCHC is the result of a 6-year long standardization effort by the IETF LPWAN Working Group, in which both industrial and academic partners took part. Some of the leading proponents contribute to this tutorial. They will explain the original design choices and the future directions taken by the WG. This technology is being intensively studied by several universities worldwide and taken up by industry through other standardization bodies such as the LoRa Alliance or the DLMS User Association, dealing with the world of electricity meters. Other use cases are under study for industrial and home automation networks. SCHC applies to several network technologies such as Sigfox, LoRaWAN, and 4G/5G. A fundamental Internet Protocol (IP) stack knowledge is required to benefit from this tutorial. The targeted audience encompasses: teaching staff intending to include SCHC as a topic in their class and hands-on, Master level students, Ph.D. candidates and researchers eager to improve or adapt SCHC to new environments, members of Standard Defining Organizations (SDO) considering including SCHC as a building block in their standards. In addition to the slideware-delivered content, the tutorial will feature demonstrations on the openSCHC platform.
