Compression Detection

A project where there are two network applications that work together to detect whether network compression is present.
One application is a client/server application and the other application is a standalone application which works in an uncooperative environment.
That is, the application detects network compression without requiring a special software being installed on the other host.
This is inspired by the work:
End-to-End Detection of Compression of Traffic Flows by Intermediaries

Requirements

YOU MUST HAVE A LINUX MACHINE IN ORDER TO BE ABLE TO RUN THIS PROGRAM. JSON ALSO MUST BE INSTALLED. PLEASE REFER TO INSTALLATION IF YOU HAVE PROBLEMS INSTALLING JSON

Installation

This program also requires you to download JSON. To install both JSON and the appllication on your linux computer/machine input the following commands into your terminal.

sudo apt install libjson-c-dev
#Now to install the repository
git clone http://github.com/dennisdang17/Compression-Detection.git

Usage

Client Server Application

1. Change the JSON file to the correct parameters you wish to use.
   The Config file contains :

    1. The Server’s IP Address
    2. Source Port Number for UDP
    3. Destination Port Number for UDP
    4. Destination Port Number for TCP Head SYN, x
    5. Destination Port Number for TCP Tail SYN, y
    6. Port Number for TCP (Pre-/Post- Probing Phases)
    7. The Size of the UDP Payload in the UDP Packet Train, (default value: 1000B)
    8. Inter-Measurement Time, γ (default value: 15 seconds)
    9. The Number of UDP Packets in the UDP Packet Train, n (default value: 6000 )
    10. TTL for the UDP Packets (default value: 255 )

2. Compile the source code with the commands below\

//Compile on server machine
gcc server.c -ljson-c -Wall -o "name of executable"

//Compile on client machine
gcc client.c -ljson-c -Wall -o "name of executable"

3. Run the application
   MAKE SURE TO RUN APPLCIATION ON SERVER SIDE FIRST

#On the server system
./"name of executable" myconfig.json
#On the client system
./"name of executable" myconfig.json
