Latency Test

1. Latency client will send curl request to /ping then server will return "pong" then measure total latency between send vs receive
2. Latency server will send 100 MB dummy binary to client to measure download speed Mbps

How to run server

Initial npm and install dependencies

npm init -y
npm install

Run node server

node server.js

How to run latency test

Modify parameter file parameters.json or create new file

parameter format

{
    "targets": [
      {

};

Execution

node latencyTest.js

Remark: if not -p specific client.js will load parameters from parameter.json
