---------------

Algorithm benchmarks

(only on Linux and FreeBSD)

0. setup 

sudo apt-get install google-perftools libgoogle-perftools-dev cmake build-essential gdb libssl-dev pkgconf tmux

1. build

mkdir release
cd release
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -G "CodeBlocks - Unix Makefiles" ..
make microbenchmarks -j4

2. run tests

./microbenchmarks

DPDK benckmarks

0. setup

1) login on CloudLab
2) create profile: two physical machines with two physical links between them
3) image: Ubuntu 16.04 or higher
3) deploy on Wisconsin cluster
4) compile DPDK 18.11 on both nodes and pktgen 3.5.9 on node 1
5) insert DPDK driver on both nodes
7) sudo apt-get install google-perftools libgoogle-perftools-dev cmake build-essential gdb libssl-dev pkgconf tmux

1. build

1) on Node 1 (work as forwarder)
cd this-code-directory 
make -j4

2) on Node 2 (work as packet generator and bandwidth meter)
cd pktgen-installation-directory/ 
cp gen_pcap.py gen_pcap.sh pktgen-installation-directory/
generate packets source files """ ./gen_pcap.sh """

2. run

1) on Node 1 (work as forwarder)
cd this-code-directory 
./run.sh skip l2 16000                   (for LudoForwarder, single thread)
./run-parallel.sh skip l2 16000          (for LudoForwarder, multiple threads)

2) on Node 2 (work as packet generator and bandwidth meter)

cd pktgen-installation-directory/ 
./pktgen -l 0-7 -n 4 --  --rx "(0,0,0),(1,0,1)" --tx "(0,0),(1,1)" --w "2,3,4,5,6,7" -f l2z-16000.pcap   (for L2 valid packets, Zipfian distribution )
