This blueprint runs UERANSIM in place of gNBsim, providing a second way to direct workload at SD-Core. Of particular note, UERANSIM runs iperf3, making it possible to measure UPF throughput. (In contrast, gNBsim primarily stresses the Core's Control Plane.)
The UERANSIM blueprint includes the following:
Global vars file vars/main-ueransim.yml gives the overall blueprint specification.
To install ueransim, follow these steps:
- Inventory file hosts.ini needs to be modified to identify the server that is to run UERANSIM. Currently, a second server is needed, as UERANSIM and SD-Core cannot be deployed on the same server.
