CCP-Chromium

QUIC Datapath Control Module for Chromium

Introduction

Congestion Control Plane (CCP) for Chromium (ccp-chromium) is a implementation of aSTEAM Project https://asteam.korea.ac.kr's QUIC Datapath Control Module in the user space Chromium network stack compatible with ccp-agent https://github.com/mit-nms/ccp of Networks and Mobile Systems (NNS) group, MIT CSAIL. Although it is designed to integrate itself into QUIC Datapath, the current published version does not contain the integration code parts. Rather, it can operate as an independent process maintaining Transport Layer Protocol's Datapath state while communicating with ccp-agent.

Requirements and Dependencies

• An UNIX-like Operating System which supports UNIX Domain Socket (UDS) Inter-Process Communication, since QUIC Datapath Control Module communicates with ccp-agent using UDS.
• A standard C++11 Compiler: g++ is recommended
• ccp-agent: an experimental implementation of CCP written in the Go Programming Language, operated as an aSTEAM Controller. https://github.com/mit-nms/ccp

Instructions

• Build Instructions of ccp-agent

  1. Open a terminal
  2. Install the Go tools: Please refer https://golang.org/doc/install.
  3. Following 'How to Write Go Code' https://golang.org/doc/code.html, organize your Go workspace
  4. Go to src directory of your Go workspace: cd $GOPATH/src
  5. Make directories github.com/mit-nms: mkdir -p github.com/mit-nms
  6. Go to mit-nms directory: cd github.com/mit-nms
  7. Clone ccp-agent's Git repository: git clone https://github.com/mit-nms/ccp
  8. Go to ccp-agent's Git repository: cd ccp
  9. Install required dependencies of ccp-agent: go get ./...
  10. Build ccp-agent: make

• Build Instructions of ccp-chromium

  1. Open a terminal and go to an appropriate directory (We assume the directory is user's home directory ~.)
  2. Clone this Git repository: git clone https://github.com/ku-asteam/ccp-chromium.git
  3. Go to the local Git repository: cd ccp-chromium
  4. Build the code with make: make all

• How to Run (In Case of TCP Reno Congestion Algorithm)

  1. $GOPATH/src/github.com/mit-nms/ccp/ccpl --datapath=udp --congAlg=reno
  2. ~/ccp-chromium/testccp
