Usage

How to configure E2Sim to initiate the connection towards E2Term(nRT-RIC)



  • Get endpoint of Kong service

MyExample: script

KONG_SVC=$(kubectl get svc -A | grep "kong" | awk '{print $2}')

NODE_PORT=$(kubectl get --namespace ricplt -o jsonpath="{.spec.ports[0].nodePort}" services $KONG_SVC)

NODE_IP=$(kubectl get nodes -o jsonpath="{.items[0].status.addresses[0].address}")

KONG_ADDRESS=${NODE_IP}:${NODE_PORT}

  • Get endpoint of E2Term List from E2Mgr

MyExample: script

NUM_OF_E2T=$(curl -sX GET "http://${KONG_ADDRESS}/e2mgr/v1/e2t/list" -H "accept: application/json" | jq '.')



for id in $(seq 1 ${NUM_OF_E2T}); do

NODE_IP=$(kubectl get pod -n=ricplt -l app=ricplt-e2term-"${id}" -o jsonpath="{.items[0].status.hostIP}")

  NODE_PORT=$(kubectl get svc -n=ricplt service-ricplt-e2term-sctp-"${id}" -o jsonpath="{.spec.ports[0].nodePort}")

  E2T_ADDRESSES[$id]="${NODE_IP}:${NODE_PORT}"

done

  • Set E2Term endpoint as parameter for E2 Simulator executable (Ref.: https://gerrit.o-ran-sc.org/r/gitweb?p=sim/e2-interface.git;a=blob;f=e2sim/e2sm_examples/kpm_e2sm/Dockerfile;h=97353530f2f1495177747ea657cc1e0b53538673;hb=HEAD)

MyExample: helm chart

spec:

      containers:

        - name: …..

          image: …..

          imagePullPolicy: …..

          restartPolicy: …..

          command: ["/bin/sh"]

          args: ["-c", ${EXECUTABLE with E2TERM ENDPOINT} ]

Building docker image and running simulator instance

To start building docker image one should generate the .deb packages using following commands :

$ cd build // create folder if not present

Generate .deb packages and move it to e2sm_examples/kpm_e2sm folder (on plain Ubuntu you might need to install "apt install cmake c++ libsctp-dev")

cmake .. && make package && cmake .. -DDEV_PKG=1 && make package cp *.deb ../e2sm_examples/kpm_e2sm/

Now we are ready to build the docker image using below command. In the Dockerfile replace 10001 → 10002.


cd ../e2sm_examples/kpm_e2sm/ docker build -t <simulator-image-name> .



if you wish to change the e2t address to connect then modify the Dockerfile in e2sm_examples/kpm_e2sm/ path.


CMD kpm_sim 10.110.102.29 36422



Create instance of simulator :


$ docker run <simulator-image-name>



It will connect to specified e2t instance.


Building docker image and running simulator instance as helm chart


o start building docker image one should generate the .deb packages using following commands :

$ cd build // create folder if not present

Generate .deb packages and move it to e2sm_examples/kpm_e2sm folder (on plain Ubuntu you might need to install "apt install cmake c++ libsctp-dev")

cmake .. && make package && cmake .. -DDEV_PKG=1 && make package cp *.deb ../e2sm_examples/kpm_e2sm/

Now we are ready to build the docker image using below command. In the Dockerfile replace 10001 → 10002.


cd ../e2sm_examples/kpm_e2sm/ docker build -t e2simul:0.0.2 .



if you wish to change the e2t address to connect then modify the Dockerfile in e2sm_examples/kpm_e2sm/ path.


CMD kpm_sim 10.110.102.29 36422


Find the correct IP address to specify there using: $ kubectl get svc -n ricplt | grep -i e2term-sctp

Start the helm chart:

helm install e2sim ./helm -n ricplt
