The Stratum community is pleased to announce the release of Stratum 2022-03-18 (or 22.03 for short) including hardware targets that have been certified for this new release. A Stratum Core Contributors Program has also been launched and community members are invited to join.

Stratum v22.03 Overview

The Stratum 2022-03-18 release (or 22.03 for short), contains a number of new features and bug fixes, including:

  • Stratum now uses P4Runtime canonical byte strings by default.
    • For stratum_bfrt targets, the old behavior can be enabled with the enable_bfrt_legacy_bytestring_responses flag.
  • P4Runtime metadata translation is now experimentally supported for stratum_bfrt and is enabled with the experimental_enable_p4runtime_translation flag.
  • Support for Intel P4Studio 9.5.2, 9.7.1, and 9.8.0 (9.3.x is no longer supported)
    • Starting with 9.7.0, only stratum_bfrt is supported, and stratum_bf will be removed for all versions in the next release.

Hardware Certified for the Stratum v22.03 Release

The following hardware targets have been certified by ONF's Continuous Certification Program for the Stratum v22.03 release and will continue to be re-verified on a daily basis against the most recent version of the software. Details about these products can be viewed in the ONF Marketplace.

Pre-built Docker images and Debian packages, along with a more extensive change list, can be accessed on the Stratum 2022-03-18 release page.
