Real Time Traffic Balancing : An intelligent approach to Network Congestion

RTP Client-Server with NS-3

Overview

This project implements an RTP (Real-time Transport Protocol) client-server model using NS-3 (Network Simulator 3). The system supports Forward Error Correction (FEC) and Congestion Control to enhance reliability and efficiency in real-time communication.

Features

• RTP Server: Handles RTP packets, supports FEC & Congestion Control, and simulates network jitter & packet loss.
• RTP Client: Sends RTP packets, supports FEC, and handles jitter & delay compensation.

File Structure

Installation & Setup

Prerequisites

• NS-3 (Network Simulator 3)
• C++ compiler (GCC)
• Linux-based OS (Ubuntu recommended)

Steps to Run

1. Compile the files: Move to the correct directory(scratch) where all above mentioned programs are present.

   cd ~/ns-allinone-3.35/ns-3.35/scratch

   Compile rtp-server.cc in one terminal

   g++ rtp-server.cc -o rtp-server

   Open another terminal and compile rtp-client.cc

   g++ rtp-client.cc -o rtp-client

Alternaive: Move to the correct directory(scratch) where all above mentioned programs are present.

 cd ~/ns-allinone-3.35/ns-3.35/scratch

Compile rtp-server.cc in one terminal

 g++ -std=c++11 -o rtp-server-main1 rtp-server-main1.cc rtp-server.cc \
-I../build -I../src/core -I../src/network -I../src/internet -I../src/applications -I../src/point-to-point \
-L../build/lib \
-lns3.35-core-debug \
-lns3.35-network-debug \
-lns3.35-internet-debug \
-lns3.35-applications-debug \
-lns3.35-point-to-point-debug \
-lns3.35-stats-debug \
-lns3.35-bridge-debug \
-lns3.35-traffic-control-debug

Open another terminal and compile rtp-client.cc

g++ -std=c++11 -o rtp-client rtp-client-main.cc rtp-client.cc \
-I../build -I../src/core -I../src/network -I../src/internet -I../src/applications \
-I../src/point-to-point -L../build/lib \
-lns3.35-core-debug -lns3.35-network-debug -lns3.35-internet-debug \
-lns3.35-applications-debug -lns3.35-point-to-point-debug \
-lns3.35-stats-debug -lns3.35-bridge-debug -lns3.35-traffic-control-debug

2. Run the Server(On one terminal):

   ./rtp-server

3. Run the Client(On another terminal,you can try running multiple client on different terminals):

   ./rtp-client

Configuration

Modify the source files to customize(if required, otherwise use the file given in this repository):

• Server Port: Change int port = 8080; in rtp-server-main1.cc and rtp-client-main.cc
• Enable/Disable Features:

  server.enableFEC(true);
  server.enableCongestionControl(true);

  client.enableFEC(true);
