¿µ¹®³»¿ë¿ä¾à This standard specifies procedures and managed objects for Asynchronous Traffic Shaping, as one of forwarding mechanism for Time-Sensitive Networking. Asynchronous Traffic Shaping can be modeled as a layer of shaped first-in-first-out (FIFO) queues that are merged into per traffic class FIFO queues in transmission ports. The required minimum number of shaped FIFO queues is adjustable and at least the number of reception ports of a particular bridge.
This standard specifies an information model for the capabilities of Asynchronous Traffic Shaping. It further specifies a YANG data model based on that information model to support configuration and status reporting. It further defines the relationship between the models introduced by this amendment and the
models in the base standard (IEEE Std 802.1QTM-2018 as amended specifically by IEEE Std 802.1QcpTM-2018 and IEEE Std 802.1QcxTM-2020).
Additionally, this standard provides an informative framework for worst-case delay analysis in static networks with static configurations.
