SD-RAN is ONF’s new exemplar platform for 3GPP compliant software-defined RAN that is consistent with the O-RAN architecture.
Starting with a micro-ONOS based near-Real-Time RAN Intelligent Controller (RIC), the exemplar platform also aims to develop open source components for the control and user planes of the Central Unit and the Distributed Unit of the disaggregated RAN in close coordination with the O-RAN Alliance and O-RAN Software Community.
The SD-RAN solution involves work in the following areas
O-RAN compliant interfaces E2, O1, A1 and protocols ASN.1, SCTP, NETCONF etc
Clustered micro-ONOS architecture for HA and Performance
Integration with 3rd party xApp vendors
Develop an SDK that makes xApps portable across RIC implementations
Integration with 3rd party CU/DU vendors
Develop ONF’s own O-RAN compliant RU/CU/DU to serve as exemplar
Develop ONF’s own O-RAN compliant Ran-Simulator for scale testing
Develop sdRan-in-a-Box (RiaB), a complete e2e solution for dev/test & reference
Contribute learnings of new SMs and app-sdk back to O-RAN and OSC
Releases every quarter with regression test suites on physical test-pods
