ork) equipment are starting to support NETCONF on their devices as well. Yet Another Next Generation (YANG) is a data modeling language (DML) that is used to model configuration, state data, and administrative actions to be used by network configuration protocols such as NETCONF. YANG was originally published in September 2010 as RFC 6020, and it was updated in August 2016 by RFC 7950 to YANG 1.1. YANG allows the definition of a unified model to describe a service as well as device configurations and is referred to as a YANG model. A central network orchestrator (or network configuration server) utilizes the YANG model(s) to configure devices in the network using the NETCONF protocol (this is different from a PTP man- agement node). Thus, the NETCONF protocol is a generic implementation that acts on YANG mod- els, conceptually the same as how SNMP acts on MIBs. In theory, a new network service should only require a new YANG model to enable network-wide configurations. While YANG models have already been standardized for many protocols, at the time of writing, a standardized YANG model for PTP is still not complete. IETF RFC 8575, published in May 2019, is a proposed standard for a YANG data model for PTP. This proposed model targets only the IEEE 1588-2008 default profiles, which means the data model only includes the standard dataset mem- bers specified by IEEE 1588-2008. The optional features (as specified in clauses 16 and 17) of IEEE 1588-2008 did not always specify datasets, SO it is not clear how to manage those features using a data model. Several shortcomings in the 1588-2008 version were rectified in the 2019 version, which will simplify the development of a model-such as making all features to be managed available as a dataset. Similarly, the telecom profiles are not covered by the model in this RFC, as there are features in those profiles that are not captured in 1588-2008. Such omissions (albeit not deliberate) and the continuing evolution of network protocols are anti- cipated by YANG, and the standa
