ISO/IEC/IEEE 8802-1Q:2024/Amd 39:2026 - Telecommunications and exchange between information technology systems — Requirements for local and metropolitan area networks — Part 1Q: Bridges and bridged networks — Amendment 39: YANG data models for the credit-based shaper
Overview
ISO/IEC/IEEE 8802-1Q:2024/Amd 39:2026 is an international standard amendment focusing on data models for managing network traffic shaping within local and metropolitan area networks (LAN/MAN). Titled "YANG Data Models for the Credit-Based Shaper," this amendment specifies YANG data models that support configuration and status reporting for the credit-based shaper algorithm in both bridges and end stations, as part of the IEEE 802.1Q family of standards.
Developed by ISO, IEC, and IEEE, this standard offers essential tools for network operators and equipment vendors seeking automation, interoperability, and advanced traffic management in modern network environments.
Key Topics
YANG Data Models for Credit-Based Shaping
The amendment introduces YANG modules that represent the management objects necessary for configuring and monitoring credit-based shaper algorithms. These models enable standardized management interfaces for both bridges and end stations.Augmentation of Existing Models
The credit-based shaper model extends the Bridge Port model, enhancing manageability for devices implementing the IEEE 802.1Q traffic shaper mechanisms.Security Considerations
The amendment highlights that the YANG modules include objects that, if improperly managed, may interfere with network stability. Operators are advised to control access to key configuration parameters to prevent accidental or malicious activity.Modular Integration
Multiple YANG modules are defined, such asieee802-dot1q-cbsaandieee802-dot1q-cbsa-bridge, which can be incorporated into broader network management platforms.
Applications
Implementing the YANG data models described in ISO/IEC/IEEE 8802-1Q:2024/Amd 39:2026 provides several practical benefits:
Automated Network Management
These models enable automated configuration, monitoring, and adjustment of traffic shaping features, facilitating programmability in software-defined networks (SDN).Interoperability Across Vendors
The standardized YANG modules ensure consistent management of credit-based shaper parameters, promoting multi-vendor compatibility within LAN and metropolitan network infrastructure.Enhanced Service Quality
Applying the credit-based shaper algorithm allows for more predictable network performance by controlling traffic flows based on defined priorities and rates, particularly valuable in converged networks with mixed traffic types.Support for Time-Sensitive Networking (TSN)
The models align closely with TSN requirements, enabling reliable, low-latency data transport, crucial for applications in industrial automation, audio/video bridging, and critical communications.
Related Standards
This amendment is part of the broader suite of IEEE 802.1Q standards, which define technical requirements and management protocols for bridges and bridged networks. Relevant related standards include:
- IEEE Std 802.1Q-2022 – The foundational bridging standard for LAN/MAN.
- IEEE Std 802.1Qcz-2023, 802.1Qcw-2023, 802.1Qcj-2023, and 802.1Qdj-2024 – Earlier amendments that address advanced network features like stream reservation and time-sensitive networking.
- YANG Data Modeling Standards – Provides foundational guidance on network device management using the YANG language.
For comprehensive network solutions, implementers should consult these related documents to ensure holistic and interoperable management of traffic shaping and quality of service across diverse network platforms.
By leveraging the guidance in ISO/IEC/IEEE 8802-1Q:2024/Amd 39:2026, network engineers and product developers can enhance automation, visibility, and control in LAN and MAN environments, positioning their networks for current and future demands.

Comments on standards
Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of
membership affiliation with IEEE or IEEE SA. However, IEEE does not provide interpretations,
consulting information, or advice pertaining to IEEE Standards documents.
Suggestions for changes in documents should be in the form of a proposed change of text, together with
appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is
important that any responses to comments and questions also receive the concurrence of a balance of interests.
For this reason, IEEE and the members of its Societies and subcommittees of the IEEE SA Board of
Governors are not able to provide an instant response to comments or questions except in those cases where the
matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests.
Any person who would like to participate in evaluating comments or revisions to an IEEE standard is welcome
to join the relevant IEEE SA working group. You can indicate interest in a working group using the Interests
tab in the Manage Profile & Interests area of the IEEE SA myProject system. An IEEE Account is needed to
access the application.
Comments on standards should be submitted using the Contact Us form.

compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of
any unfair discrimination to applicants desiring to obtain such licenses.
Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not
responsible for identifying Essential Patent Claims for which a license may be required, for conducting
inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or
conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing
agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that
determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their
own responsibility. Further information may be obtained from the IEEE Standards Association.
IMPORTANT NOTICE
Technologies, application of technologies, and recommended procedures in various industries evolve over
time. The IEEE standards development process allows participants to review developments in industries,
technologies, and practices, and to determine what, if any, updates should be made to the IEEE standard.
During this evolution, the technologies and recommendations in IEEE standards may be implemented in
ways not foreseen during the standard’s development. IEEE standards development activities consider
research and information presented to the standards development group in developing any safety
recommendations. Other information about safety practices, changes in technology or technology
implementation, or impact by peripheral systems also may be pertinent to safety considerations during
implementation of the standard. Implementers and users of IEEE Standards documents are responsible for
determining and complying with all appropriate safety, security, environmental, health, data privacy, and
interference protection practices and all applicable laws and regulations.
