Comcores Radio Over Ethernet Structure Agnostic Mapper/Demapper IP core is a silicon agnostic implementation of the structure agnostic mapping method described in the IEEE 1914.3 standard. The RoE IP-core takes multiple streams of CPRI data and map these into one or several 10G/25G Ethernet data streams and vice versa. The RoE IP core does as well allow for local injection and retraction of Ethernet traffic.
