It’s the data model! Powerful and versaRle data modeling language YANG Standard data modeling language of choice at IETF for management. Simple data types Modules, sub-modules unsigned integer, integer, string, Templates enumeraRon, bits, binary, empty Extending data models Unions Condi>ons (if-feature) Labels (idenRty) Extensible enumera>ons References to labels, data items, etc. CollecRons All public YANG modules Sets, lists April, 2017 Structures (composite types) Andy Bierman, Michel Veille1e, Peter van der Stok, Alexander Pelov

Data model as contract YANG Server Client (To be managed) Andy Bierman, Michel Veille1e, Peter van der Stok, Alexander Pelov

And the interacRon model! YANG Server NETCONF Client (To be managed) Rich interacRon model Andy Bierman, Michel Veille1e, Peter van der Stok, Alexander Pelov

And the protocol bindings! YANG Server NETCONF Client (To be managed) XML YANG RPC NETCONF HTTP TCP IP Andy Bierman, Michel Veille1e, Peter van der Stok, Alexander Pelov

And the protocol bindings! YANG Server RESTCONF Client (To be managed) XML JSON YANG RPC REST / RPC RESTCONF NETCONF HTTP HTTP TCP TCP IP IP Andy Bierman, Michel Veille1e, Peter van der Stok, Alexander Pelov
