 This page describes how to run current implementation for the O-DU Slice Assurance usecase. 


Standalone script version

The standalone script version of the usecase is implemented in Golang. 

It provides a simulator that stub both Dmaap MR and SDNR (orange boxes in the picture below), so both processes can share its data.

Prerequisites

The following need to be installed to run the script according to these instructions:

  1. Go must be installed, see https://go.dev/doc/install.
  2. Pull the nonrtric repo, https://gerrit.o-ran-sc.org/r/admin/repos/nonrtric.

Run

Run Dmaap MR / SDNR stub 

This stub has been coded on Go, similar to the simulator used in O-RU O-DU Closed loop recovery use case previously described. However,  this stub simulates both Dmaap VES messages and also SDNC. By default, the stub listens to port 3905, can be changed with the flag "--sdnr-port". 

To run the stub, follow the steps below:

  1. Goto "test/usecases/odusliceassurance/goversion/stub" in the repo.
  2. Build the stub, "go build".
  3. Start the stub, "./stub"


Run simulator 
cd nonrtric/test/usecases/odusliceassurance/goversion/stub
go build
./stub [--sdnr-port <portNo>] [--dmaap-port <portNo>]
 
Example:
└─ $ ▶ ./sdnr --sdnr-port 3906
Starting DmaapMR stub on port:  3905
Starting SDNR stub on port:  3606

Run O-DU Slice Assurance Rapp

The application takes a number of environment variables for configuration, but only MR_HOST and MR_PORT are required, others are optional. More information can be found in README.md file


Run Rapp 
cd nonrtric/test/usecases/odusliceassurance/goversion/
go build
./oduclosedloop


Environment variables can be defined as part of the command line as follow:


Run rapp with environment variables 
Example:
└─ $ ▶ MR_HOST=http://localhost MR_PORT=3905 ./oduclosedloop
