ONF is pleased to announce the release of SD-RAN v1.1, a cloud-native open source implementation of software-defined RAN consistent with the O-RAN architecture.

A major highlight of this release is the collaboration between ONF and two project collaborators (AirHop and Facebook) towards a demonstration of SON functionality as an xApp, demonstrating the first multi-vendor xApp solution and proving the power of a RIC-based open RAN architecture. 

SD-RAN v1.1 includes the µONOS-based nRT-RIC, a white box-based CU/DU/RU solution with LTE support, and a completely virtualized dev/test environment called RiaB (“sdRan-in-a-Box”). 

Other release features and enhancements include: 

  • ONF’s RAN simulator (RANSim) is now O-RAN compliant in its use of the E2 interface and Service Models (SMs) when interacting with the nRT-RIC. 
    • RANSim was completely re-architected to simulate dozens of E2 nodes, and simultaneously support multiple Service Models (SMs) such as KPM and RC-PRE SMs. 
    • Runtime gRPC APIs were added to support CRUD operations on E2 nodes, cells and their attributes. 
    • A supporting utility was added that can be loaded into RANSim to create a RAN topology.
  • The entire SD-RAN stack was upgraded to support O-RAN standardized KPM-SM v2.0.03 and E2-AP v1.0.1. 
  • Lastly, RiaB can now be used in three different modes, depending on the use case.
