O-RAN Architecture § Our interpretation of non-RT-RIC is ONAP CCSDK/SDNC based. § O-RAN has released the first WG 4 Open Fronthaul m-plane interface specification between RU and DU § Of cause there are currently no products available “talking” Open Fronthaul. In order to proof the interface specification it is necessary to simulate the RU and the DU. § For the RU a Net. Opeer 2 based Net. Conf server is used, to simulate the DU an ODL cluster based on ONAP CCSDK/SDNC is used. 6 2/28/2021 6

Failover of Net. Conf Sessions § ODL 3 node cluster (non-RTRIC) host several Net. Conf sessions § Check for the ODL node with the most Net. Conf sessions § Kill that node § Check for when the all Net.
