P802.1Qdj – Configuration Enhancements for Time-Sensitive Networking

This amendment specifies procedures, interfaces, and managed objects to enhance the three models of ‘Time-Sensitive Networking (TSN) configuration’. It specifies enhancements to the User/Network Interface (UNI) to include new capabilities to support bridges and end stations in order to extend the configuration capability. This amendment preserves the existing separation between configuration models and protocol specifications. This amendment also addresses errors and omissions in the description of existing functionality.

The management models and User/Network Interface (UNI) already described in Clause 46: Time-Sensitive Networking (TSN) configuration of IEEE Std 802.1Q include only the concepts (e.g. in form of a YANG types module) for managing bridged LANs using Time-Sensitive Networking (TSN) features. In order to be able to fully manage such bridged LANs with TSN features, comprehensive interfaces and management modules are required that are currently not available. Enhancements are especially needed for the ‘fully centralized’ and ‘centralized network/distributed user’ configuration models. The proposed amendment will address these issues.
