17. Wimax Measurement Experiment: multiple traffic generators and single receiver

Description

The experiment runs multiple traffic generators on up to 7 (client) wimax nodes and single traffic receiver. The number of clients can be varied to study the wimax interface's ability to handle traffic at different loads. The traffic generated is UDP, the number of packets and the bit rate can be varied as well.

Hardware utilized

  1. Sandbox 4 node1-1 - node1-7: runs otg2 as generator.
  2. Sandbox 4 node1-8: runs otr2 as receiver.
  3. RF-attenuator matrix: this used prior to running the experiment to attenuate the air interface between the wimax base station and nodes.

Software / scripts worth mentioning

  1. baseline-iperf.ndz: disk image that's loaded onto the nodes. This image is loaded with otg2 / otr2.
  2. oml2-server: server running on sandbox 4 which collects measurement data from oml2-iperf and stores in a database file.
  3. sqlite3: command line interface for accessing the contents in a database file.
  4. mclient.rb: the experiment script. Click here to view file.
    1. The script takes the following parameters as arguments:
      1. nClient - number of client nodes to use, nClients = [1..7]
      2. packetsize - packet size (byte) from the sender node, packetsize max = 1024
      3. bitrate - bitrate (bit/s) from the sender node
    2. Example usage:
      1. omf-5.2 exec mclient.rb — —nClients 8 —packetsize 512 —bitrate 16000

Set up

Getting started, ssh into the console of sandbox 4.

  • Verify the oml2-server is running:
    • $ ps -elf | grep oml2-server
      nilanjan@console.sb4:~/exp/dl-iperf/5.2$ ps -elf | grep oml2-server
      4 S oml2       948     1  0  80   0 -  2471 poll_s Feb02 ?        00:00:16 /usr/bin/oml2-server -l 3003 --logfile=/var/log/oml2-server.log --user=oml2 --group=oml2
      0 S nilanjan  1259 27360  0  80   0 -  1002 pipe_w 10:59 pts/1    00:00:00 grep oml2-server
      

Before the experiment, the BS parameters can be changed. The following are a few examples commands to control the MCS:

For other details on changing BS parameters please refer to Basic Support Services under http://wimax.orbit-lab.org/wiki

Although the experiment script can vary the attenuator values, the details on manually changing attenuator values can be found in RF Matrix Control Services under http://wimax.orbit-lab.org/wiki

Usage

  • Start clean, turn off all the nodes:
    • $ omf-5.2 tell offh all
      nilanjan@console.sb4:~/exp/dl-iperf/5.2$ omf-5.2 tell offh all

A few words on post processing

This experiment generates a sqlite3 database file named with the experiment id and this file is automatically copied to the current directory. The .sql file will have several tables: _experiment_metadata, _senders, otg2_udp_out, otr2_udp_in.
In particular, otr2_udp_in table contain information about the received packets from the various senders.

The following will display the tables in the file:

  • $ sqlite3 udp_n6_p512_br1024000.sq3 ".tables"
    TABLES
    

The following will display the contents of the udp_otr2_in table:

  • $ sqlite3 -header udp_n6_p512_br1024000.sq3 "select * from otr2_udp_in"
    nilanjan@console.sb4:~/exp/mclient/5.2$ sqlite3 -header udp_n6_p512_br1024000.sq3 "select * from otr2_udp_in"
