ORAN Split 7.2 E2E

Description

This tutorial contains instructions for setting up 5G ORAN Split 7.2 network using OAI/srsRAN + various O-RUs(Lite On, Jabil, Benetel) in COSMOS SB1.

Prerequisites

In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on the COSMOS getting started page to get started.

Resources required

1 server in ​COSMOS SB1 domain and sdr1-in3(with SIMCOMM modem)

Tutorial Setup

Follow the steps below to gain access to the sandbox 1 console and set up nodes with appropriate images.

  1. If you don't have one already, sign up for a ​COSMOS account
  2. Create a resource reservation on sandbox 1
  3. Login into sandbox 1 console (console.sb1.cosmos-lab.org) with two SSH sessions.
  4. Make sure all the resources in the domain are turned off: 
    omf tell -a offh -t system:topo:allres
    For this tutorial we will be using the SB1 servers, srv1-lg1, srv2-lg1, USRP N310s in large and medium nodes, sdr1-s1-lg1 and sdr1-md1.
  5. Load 5G-tutorial-cosmos.ndz on srv1-lg1,srv2-lg1. 
    omf load -i 5G-tutorial-cosmos.ndz -t srv1-lg1
  6. Turn all the required resources on and check the status 
    omf tell -a on -t srv1-lg1,sdr1-in3

    omf stat -t system:topo:allres
  7. ssh to the servers, use option -Y for using GUI. 
    ssh root@srv1-lg1

Tutorial Execution

Initialize DPDK
