About This Training
Next-generation in-vehicle networks are faced with various challenges. Architectures are shifting to zonal, leading to more hops and more heterogenous hardware. Service-orientation and the requirements for high availability require dynamic monitoring and reconfiguration of the network. In this presentation, we will discuss if and how YANG-based configuration could help tackle those challenges.
YANG is a powerful modeling language for networking devices and functions. Developed by the IETF it has been adopted by the IEEE as the standard tool for modeling configuration and state data related to their standards. For AVB/TSN, the shift from MIBs to YANG happened somewhere in the middle of the process. Thus, some TSN standards incorporated YANG from the start, some have YANG models added as an amendment and for some, this remains a gap.
YANG models are the cornerstone of many SDN protocols like NETCONF, RESTCONF and CORECONF. Having good models of TSN and related standards is essential to enable dynamic configuration scenarios. When properly deployed YANG+SDN enables centralized configuration for protocols like the time-aware-shaper (TAS) and allows monitoring and reconfiguration in case of network faults.
Here, we will be taking stock of the existing models, the work in progress and gaps that need to be addressed in order to enable failover configuration, service-dependent network reconfiguration and so on. IEEE standards are the most essential in this story but Open Alliance and AUTOSAR® standards also play a role in this.
