ONF M-CORD lite version for K-ONE project (K-ONE-M-CORD-Lite)

M-CORD lite version for K-ONE project Note that

  • containers and SPGW-C/U software have been implemented by Intel
  • shell scripts are implemented by Woojoong Kim @ POSTECH and ONF

Specification

  • OS: Ubuntu 16.04 (Fin to test) and 18.04 (under test)
  • CPU: Intel CPU (More than Haswell CPU microarchitecture), at least 20 cores
  • Memory: 16GB
  • Disk: > 1GB

Set-up environment

Single PM version (Release 1)

  1. (Optional) Make a disk storage when using CloudLab
PM$ ./cloudlab-disk-setup.sh
  1. Install Docker and other requisites
PM$ ./set_env.sh
  1. Pull/run SPGW-C and SGPW-U images and make bridge networks
PM$ ./get_ngic_images.sh
  1. Pull traffic generator image
PM$ ./get_traffic_images.sh

Information

Network information

  • brspgw: 192.168.104.0/24
  • brs11: 192.168.103.0/24
  • brs1u: 192.168.105.0/24
  • brsgi: 192.168.106.0/24

How to access each container?

  • DP container
PM$ docker exec -it dp bash
  • CP container
PM$ docker exec -it cp bash
  • Traffic generator container
PM$ docker exec -it traffic bash

How to get IP address for each interface in each container?

  1. Access each container
  2. Input ifconfig command

Configuration

config/interface.cfg in this repository

21: dp_comm_ip = <IP address of DP container connected in `brspgw` bridge>
...
23: cp_comm_ip = <IP address of CP container connected in `brspgw` bridge>

config/cp_config.cfg in this repository

1: S11_SGW_IP=<IP address of CP container connected in `brs11` bridge>
2: S11_MME_IP=<IP address of traffic container connected in `brs11` bridge>
3: S1U_SGW_IP=<IP address of DP container connected in `brs1u` bridge>

config/dp_config.cfg in this repository

1: S1U_IP=<IP address of DP container connected in `brs1u` bridge>
...
5: SGI_IP=<IP address of DP container connected in `brsgi` bridge>
...
8: SGI_GW_IP=<IP address of traffic container connected in `brsgi` bridge>

Generate pcap files to run TCPReplay

First, access to traffic container. Then, input the following command:

root# ./rewrite_pcaps.py enb.s1u.ngic spgw.s11.ngic spgw.s1u.ngic spgw.sgi.ngic

where

enb.s1u.ngic: IP address of traffic container connected in `brs1u` bridge
spgw.s11.ngic: IP address of CP container connected in `brs11` bridge
spgw.s1u.ngic: IP address of DP container connected in `brs1u` bridge
spgw.sgi.ngic: IP address of DP container connected in `brsgi` bridge

Note that this step spends 1-2 minutes.

How to run?

Overview

To run ONF M-CORD lite version for K-ONE project, there is the sequence which is DP -> CP -> traffic generator

How to run DP?

root# . /opt/ngic/config/dp_config.cfg && ifconfig -a && ./ngic_dataplane $EAL_ARGS -- $APP_ARGS

How to run CP?

root# . /opt/ngic/config/cp_config.cfg && ifconfig -a && ./ngic_controlplane $EAL_ARGS -- $APP_ARGS

How to generate traffic for each LTE interface?

root# tcpreplay --pps=200 -i $S11_IFACE tosend-s11.pcap # to generate S11 traffic
root# tcpreplay --pps=2000 -i $S1U_IFACE tosend-s1u.pcap # to generate S1U traffic
root# tcpreplay --pps=2000 -i $SGI_IFACE tosend-sgi.pcap # to generate SGI traffic

Release information

  • Release 1 - single PM version
  • Release 2 - single PM version / multiple EPC sevices (under maintenance by Woojoong Kim @ POSTECH and ONF)
  • Release 3 - multi-PM version / multiple EPC services; each EPC runs in the same PM (TBD)
  • Release 4 - multi-PM version by using Docker Swarm (Not fixed yet)
