Radio Frequency over Ethernet (IEEE 1914.3) OUI mapping(s) using CERN's OUI

The aim of this project is to create a Radio over Ethernet (RoE) protocol, which supports the transmission of Radio Frequency (RF) signals via an Ethernet network that can meet the needs of particle accelerator facilities.

We define a structure-aware direct digital synthesis (DDS) mapping for the IEEE Standard for Radio over Ethernet Encapsulations and Mappings, IEEE Std 1914.3-2018. This is achieved using the subType mapping object mechanism and applying the organizationally unique identifier (OUI) assigned to CERN.

This DDS mapping is intended for use in systems which generate RF signals using DDS technologies. It enables a bandwidth-efficient transfer of DDS parameters, and their synchronization at International Atomic Time (TAI) timestamps.

The specification for this DDS mapping can be found here:
