Press release: Rennes, March 21st, 2023

Acklio, the world's leading vendor in Static Context Header Compression (SCHC) technology, is excited to announce the expansion of SCHC compression and fragmentation to non-LPWAN connectivities. It builds upon the success of the IETF LPWAN working group, which has been in operation since 2016 and laid the groundwork of the SCHC framework. The extended roadmap will be implemented by the new SCHC Working Group and will drive innovation and progress in SCHC technology across a wider range of use cases.

Building on the success of the LPWAN working group, the IETF is expanding the scope of SCHC compression to any kind of wireless and wired connectivity. SCHC technology, originally designed to optimize IPv6 operations over Low-Power Wide-Area Networks (LPWAN), has proven to be effective in reducing packet header sizes and facilitating data fragmentation, all while preserving crucial information for accurate routing and transmission. The RFC 8724 serves as a framework for a series of standards that specify the optimized use of SCHC for various network technologies (such as LoRaWAN, Sigfox, and NB-IoT) and application layers (including CoAP). 

The newly-formed SCHC working group is equipped with an ambitious roadmap to promote the adoption and standardization of SCHC compression in non-LPWAN networks. The SCHC framework can provide benefits for any kind of wireless or wired network. Until now, the focus of the work was to ensure the full operation in LPWANs, which have very stringent constraints and characteristics. The new work will address more generic cases, such as SCHC for mesh topologies and for networks with different bandwidth, latency and loss rates. The working group will explore the need for compression and fragmentation techniques for other application layer protocols, such as LwM2M, MQTT, and HTTP/3, and will further consider additional security and privacy measures.

Towards SCHC everywhere with Acklio. As an SCHC pioneer, Acklio's worldwide reference implementation spans across five continents for LoRaWAN, NB-IoT, RF-MESH, and satellite technologies. The company has demonstrated significant optimizations, achieving 40-90% less data traffic, 30-70% longer battery life, and up to seven times more devices per cell. It also opens new massive high added-value use-cases. 

Committed to expanding SCHC technology's reach, Acklio has developed scalable solutions that are integrated into a wide array of IoT players. By focusing on "SCHC Everywhere," the company drives innovation through pushing compression performance to its theoretical limits, ensuring accessibility across various environments, and simplifying the technology for developers. Among the latest developments are: 

  • Universal Payload Compression over SCHC, which enables additional compression techniques to be applied to protocol payloads, unlocking new levels of performance.
  • The upcoming "microIPCore" version of the core network SCHC gateway platform, designed to run in embedded, edge environments, or as an appliance in the cloud.
  • Additional options for seamless integration with any platform and service on the market: SCHC-over-Webhooks and SCHC-over-MQTT, which complement the existing direct IPv4/IPv6 and VPN options currently deployed in production.
  • Enhancing the reach of Acklio’s Embedded Library, including a new integration for the Rust Programming Language that provides a reliable, secure and efficient way to enable SCHC in any environment, any device, any platform.
"We are incredibly excited about the future of SCHC technology as it expands beyond LPWAN," says Alexander Pelov, CEO of Acklio and co-chair of the LPWAN Working Group. "This new working group will undoubtedly accelerate the adoption of SCHC across a wider range of connectivity solutions, including Wi-Fi, PPP, and Ethernet, thanks to the enthusiasm of our partners. Unleashing the full potential of IoT and enabling countless new use cases, SCHC is poised to become an essential technology for the future of connected devices.
