OpenFlow Controller Benchmarking Tool

Authors: Cavadia. Alberto & Tovar. Daniel

The objective is to develop a more extensive benchmarking tool for SDN controllers under OF 1.3, with C, than the existing tool Cbench.

NOTE: This tool was based on OFLOPS/cbench, so it has all the current options supported by them.

Features

  1. Metrics for latency and performance tests:

    a. RTT.

    b. CPU usage percent.

    c. Memory usage.

    d. Packets sent.

    e. Packets received.

    f. Number of flows.

  2. Parameters:

    a. Number of switches.

    b. Number of packets.

    c. Size of packet.

    d. Interpacket delay sending.

    e. Packet fields.

    f. Number of packets to configure.

    g. Sending order:

     i. Serial.
 
 ii. Random.

  3. Controllers supported: a. Ryu.

    b. FloodLight.

    c. OpenDayLight. d. OpenMUL.

Requirements

  1. SNMP-NET installed
  2. SNMP-MIBS-DOWNLOADER installed.
    1. Comment out "mibs:" from snmp.conf.
    2. Run download-mibs.
  3. Update snmpd.conf to accept foreigner requests:
    1. Update to agentAddress udp:161.
    2. Remove "-V systemonly" from "rocommunity public default -V systemonly".
  4. Install gnuplot on your OS with local package install manager. e.g: sudo zypper install gnuplot in OpenSuse

Comments

  1. The entire description of options is displayed with -h or --help flag.
  2. I'will try to host a couple of VM (master and slave) to make testing easier.

Instructions

  1. Generate an excutable running the makefile inside.
  2. Run the Master node with statements indicating controller IP address, port and amount of nodes, similar to: ./ofcB -C 192.168.1.108 -P 6653 -N 2
  3. Run the Slave node(s) with statements indicating in addition Master Node IP address and options for actual test similar to: ./ofcB -C 192.168.1.108 -P 6653 -s 16 -N 2 -n 192.168.1.109 -l 50
