automata

A network performance testing and visualization tool based on netperf and RRUL(Real-Time Response Under Load)

Why

Inspired by Flent, it is nice to have a network performance testing and visualization tool with time series data. This tool is intended to solve below problems of flent:

• Complexity of parameters and configurations
• Many ports and protocols needs to be opened

This tool is easy to use and only requires netperf ports (12865,12866,12867/tcp, 12866/udp) to be opened so can be easily integrated with firewall environment or Micro Services Architecture

Output example

This is an example of RRUL testing result on localhost:

How

Below are quick start instructions

Requirements

netperf with demo feature enabled (–enable-demo=yes)

apt-get update && apt-get install net-perf

Build binary

make

On Server

netserver

On Client

./build/automata -host <Server_Address> -o result.png

Client usage

Usage of ./build/automata:
  -host string
    	netserver address e.g "192.168.100.100" (default "127.0.0.1")
  -l uint
    	time in seconds the test will last (default 60)
  -o string
    	output filename of plotting, print csv data if not provided
  -p uint
    	netserver base port, port+1 and port+2 are also used (default 12865)

Docker, Kubernetes and Istio

A netperf netserver image can be pulled from:

docker pull ksang/netserver

Example of using this image with kubernetes and istio:

netserver.yaml:

apiVersion: v1
