FileĬreates the topology, measures cwnd, queue sizes and RTTs and spawns a webserver. The following are important files you will find in the repository.
#REAL TRAFFIC SPAWN INSTALL KODI INSTALL#
You also need to install curl and matplotlib by running the following commands: sudo apt update sudo apt install -y curl sudo apt install -y python-matplotlib In order to test webpage fetch time and make plots, This will extract the skeleton code to the bufferbloat directory.
#REAL TRAFFIC SPAWN INSTALL KODI HOW TO#
Learn how to package your experiments so it’s easy for others to run your code.ĭownload the skeleton code into the home directory of your virtual machine and run.Learn how to use Mininet to create network topologies, run traffic generators, collect statistics and plot them.This problem is often called “bufferbloat.” Learn why large router buffers can lead to poor performance.Learn first-hand the dynamics of TCP sawtooth and router buffer occupancy in a network.To ease our measurement, we are going to emulate the network in Mininet. In a real network it’s hard to measure cwnd (because it’s private to the server) and the buffer occupancy (because it’s private to the router). We are going to study what happens when we download data from a remote server to the End Host in this home network. The Home Router is connected via Cable or DSL to a Headend router at the Internet access provider’s office. Take a look at the figure below which shows a “typical” home network with a Home Router connected to an end host. In this project we will study the dynamics of TCP in home networks. See project 1 if you need a refresher on how to work with the Mininet environment. This project runs in the same virtual machine we used in project 1 and project 2. Then, you will generate experiment results using the framework, and answer the questions listed later in this document.įor general background on Bufferbloat, look at the following article:īufferBloat: What's Wrong with the Internet? In this project, we will use Mininet to study the dynamics of TCP and the bufferbloat phenomenon.įirst, you need to complete the TODO fields in the skeleton code of our experiment framework.
