Scope

This OPC Unified Architecture (OPC UA) series specification defines the Base Network Model (BNM) by specifying an OPC UA Information Model for a basic set of network-related components.

The initial version defines parameter sets for TSN Talkers and Listeners as well as network interfaces and ports, as shown in Figure 1 in the attached draft. A future version of this specification is expected to have a broader scope of other network technologies than Ethernet.

Purpose

The BNM shall align its parameters to existing standards defined by IETF and the IEEE to allow an effortless mapping against existing network technologies. Therefore, selected DataTypes shall fit the types used by the related managed objects of IEEE and IETF. BrowseNames of Variables and parameter sets (UA interface) are preferably derived from standardized IETF / IEEE YANG models. If no standardized YANG representation is available, MIB definitions are chosen.
