quic-on-ns3

running google quic on ns3
This repo depends on quiche library.
The quiche libarary can be got here: https://github.com/bilibili/quiche
I make some minor changes on CmakeList.txt to get shared library.
I upload the source code of quiche library on BaiduYunPan.

Build quiche

Prerequisite

apt-get install cmake build-essential protobuf-compiler libprotobuf-dev golang-go libunwind-dev libicu-dev

Build

Download quiche library first. And I unzip the quiche.zip under "/home/xxx/"

cd quiche  
mkdir build && cd build  
cmake ..  
make

Generate cert

cd quiche/util  
chmod 777 /generate-certs.sh  
./generate-certs.sh   
mkdir -p data/quic-cert  
mv ./out/*  data/quic-cert/

Build quic module on ns3

The code of quic module is tested on ns3.33.

Add environmental variable

sudo gedit /etc/profile  
export QUICHE_SRC_DIR=/home/xxx/quiche/  
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$QUICHE_SRC_DIR/build/

The reason to add QUICHE_SRC_DIR can be found quic/wscript.

build ns3

1 enble c++17 flag (ns3.33/wscript)

opt.add_option('--cxx-standard',  
               help=('Compile NS-3 with the given C++ standard'),  
               type='string', default='-std=c++17', dest='cxx_standard')

2 cope quic folder to ns3.33/src/

cd ns3.33  
source /etc/profile  
./waf configure  
./waf build

Run example

1 put the file quic-main.cc(scratch) to ns3.33/scratch/
2 set string varible quic_cert_path in quic-main.cc
3 set string varible log_path in quic-main.cc to collect traced data.

std::string quic_cert_path("/home/xxx/quiche/utils/data/quic-cert/");  
std::string log_path=std::string("/home/xxx/traces/")+algo+"/";

3 Run example(BBR)

source /etc/profile  
./waf --run "scratch/quic-main --cc=bbr"

3 Run example(BBR)

source /etc/profile  
./waf --run "scratch/quic-main --cc=cubic"

Results

data can be found under folder ("/home/xxx/traces/")
copy the file plot-script/data_plot.sh to "/home/xxx/traces/bbr"
plot the results:

chmod 777  data_plot.sh  
./data_plot.sh
