Introduction
============
<INTRODUCTION TO THE SCOPE AND INTENTION OF THIS DOCUMENT AS WELL AS TO THE SYSTEM TO BE INSTALLED>
This document describes the supported software and hardware configurations for the OPNFV C-RAN project relative reference as well as providing guidelines on how to install and
configure such reference system.
Although the available installation options gives a high degree of freedom in how the system is set-up,
with what architecture, services and features, etc., not nearly all of those permutations provides
a OPNFV compliant reference architecture. Following the guidelines in this document ensures
a result that is OPNFV compliant.
The audience of this document is assumed to have good knowledge in network and Unix/Linux administration.
Preface
=======
<DESCRI
BE NEEDED PREREQUISITES, PLANNING, ETC.>
Before starting the installation of C-RAN@OPNFV, some planning must preceed.
First of all, you need to download OAI eNodeB and UE tar packeage and have them installed.
link as follow :
The eNodeB code link :
https://drive.google.com/open?id=1_BiK2vgfxdHg3hsBxvwCObcal3bVP0SD
The UE code link:
https://drive.google.com/open?id=1pwepCkk2FU6hClRL_lLnsTVYkKkGcUci
Software requirements
=====================
you will need a node of baremental envirment with two VMs.
Host OS: centos x86_64-linux-3.10.0-51.el7.x86_64
Guest os: ubuntu 14.04.3 linux kernel>=3.19
VM model: Memory: 4GB, hard disk: 15GB, vCPU: 2
Hardware requirements
=====================
Following minimum hardware requirements must be met for installation of C-RAN@OPNFV:
Suggeted hardwrare, other capable hardware is fine.
HP DL380 PGen8, memory 64G, frequency 3.0, network card 100Mbps, hard disk 600GB
Installation manual
================================================
Based on the OAI community, CMCC contributes different version of BBU function realization. CMCC will update code when the internal legal process finished.
I. Initial environment construction
1. Operating System : ubuntu14.04 version, linux kernel 3.19
2. In VM1, decompress the eNB.tar. In VM2, decompress the UE.tar.
eNB.tar and UE.tar can be stored anywhere you like, take /home/ as an example.
cd /home/
tar –xzvf eNB.tar
tar –xzvf UE.tar
3. Run the following command in two VMs respectively:
Open directory: cd openairinterface5g-develop-nos1/cmake_targets
Executive command (under root mode): ./build_oai -I --oaisim -x --install-system-files
Intall the lib and related tools.
II. VM1 configuration:
1. Open directory: openairinterface5g-develop-nos1/cmake_targets
2. Run the script: sh build_rcc.sh
3. Run the script: sh run_rcc.sh
III. VM2 configuration
1. Configure the VM external communication IP
(1) Open file: openairinterface5g-develop-nos1/targets/PROJECTS/GENERIC-LTE-EPC/CONF/ rru.oaisim.conf
(2) Modify the local network address, including the UE IP and local network port IP.
RUs=(
{
local_if_name = "";//Local network port name, e.g.eth0
remote_address = ""; //UE IP
local_address = "";// IP of local network port
……
}）
2. Code compiling:
(1) Open directory: openairinterface5g-develop-nos1/cmake_targets
(2) Run the script: sh build_rcc.sh
(3) Run the script: sh run_rcc.sh
(4) access success: In VM1, get the following log RRCConnectionReconfigurationComplete
(5) Test case description
Test objection: Test the NFVI platform supporting for radio access network
Test index: Observe the downlink bandwidth of radio access network
Test scheme: Launch the Iperf function respectively in VM1 and VM2. The UE VM launches the iperf server, eNB launches the iperf client.
Test procedure:
IP: eNB ip is 10.0.1.1, UE ip is 10.0.1.2 (If you want to modify the ip, check the openairinterface5g-develop-nos1/targets/tools/init_nas_nos1)
The destination IP is: 10.0.1.2, , the source IP is: 10.0.1.1
Under UDP mode, Iperf client sends the packets to iperf server, the test time continues 120s, the number of connection is one, the packet loss limit to 0.6%, recording the network bandwidth.
Futher test command can be found on C-RAN wiki page:
