+## How To Benchmark Client-Server Throughput using hiperf
+
+### hicn-light-daemon
+
+This tutorial will explain how to configure a simple client-server topology and retrieve network measurements using the hiperf utility.
+
+We consider this simple topology, consisting on two linux VM which are able to communicate through an IP network (you can also use containers or physical machines):
+
+```text
+|client (10.0.0.1/24; 9001::1/64)|======|server (10.0.0.2/24; 9001::2/64)|
+```
+
+Install the hICN suite on two linux VM. This tutorial makes use of Ubuntu 18.04, but it could easily be adapted to other platforms.
+You can either install the hICN stack using binaries or compile the code. In this tutorial we will build the code from source.
+
+```bash
+$ curl -s https://packagecloud.io/install/repositories/fdio/release/script.deb.sh | sudo bash
+$ apt-get install -y git \
+                    cmake \
+                    build-essential \
+                    libasio-dev \
+                    libcurl4-openssl-dev \
+                    libparc-dev \
+                    --no-install-recommends
+
+$ mkdir hicn-suite && cd hicn-suite
+$ git clone https://github.com/FDio/hicn hicn-src
+$ mkdir hicn-build && cd hicn-build
+$ cmake ../hicn-src -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../hicn-install -DBUILD_APPS=ON
+$ make -j 4 install
+$ export HICN_ROOT=${PWD}/../hicn-install
+```
+
+It should install the hICN suite under hicn-install.
+
+#### hICN stack based on hicn-light forwarder with UDP faces
+
+##### Server Configuration
+
+Create a configuration file for the hicn-light forwarder. Here we are configuring UDP faces.
+
+```bash
+server$ mkdir -p ${HICN_ROOT}/etc
+server$ LOCAL_IP="10.0.0.1" # Put here the actual IPv4 of the local interface
+server$ LOCAL_PORT="12345"
+server$ cat << EOF > ${HICN_ROOT}/etc/hicn-light.conf
+add listener udp list0 ${LOCAL_IP} ${LOCAL_PORT}
+EOF
+```
+
+Start the hicn-light forwarder
+
+```bash
+server$ sudo ${HICN_ROOT}/bin/hicn-light-daemon --daemon --capacity 0 --log-file ${HICN_ROOT}/hicn-light.log --config ${HICN_ROOT}/etc/hicn-light.conf
+```
+
+We set the forwarder capacity to 0 because we want to measure the end-to-end performance without retrieving any data packet from intermediate caches.
+
+Run the [hiperf](#hiperf) server.
+
+```bash
+server$ ${HICN_ROOT}/bin/hiperf -S b001::/64
+```
+
+The hiperf server will register the prefix b001::/64 on the local forwarder and will reply with pre-allocated data packet.  In this test we won't consider segmentation and reassembly cost.
+
+##### Client Configuration
+
+Create a configuration file for the hicn-light forwarder at the client. Here we are configuring UDP faces.
+
+```bash
+client$ mkdir -p ${HICN_ROOT}/etc
+client$ LOCAL_IP="10.0.0.2" # Put here the actual IPv4 of the local interface
+client$ LOCAL_PORT="12345"
+client$ REMOTE_IP="10.0.0.1" # Put here the actual IPv4 of the remote interface
+client$ REMOTE_PORT="12345"
+client$ cat << EOF > ${HICN_ROOT}/etc/hicn-light.conf
+add listener udp list0 ${LOCAL_IP} ${LOCAL_PORT}
+add connection udp conn0 ${REMOTE_IP} ${REMOTE_PORT} ${LOCAL_IP} ${LOCAL_PORT}
+add route conn0 b001::/16 1
+EOF
+```
+
+Run the hicn-light forwarder
+
+```bash
+client$ sudo ${HICN_ROOT}/bin/hicn-light-daemon --daemon --capacity 1000 --log-file ${HICN_ROOT}/hicn-light.log --config ${HICN_ROOT}/etc/hicn-light.conf
+```
+
+Run the [hiperf](#hiperf) client:
+
+```bash
+client$ ${HICN_ROOT}/bin/hiperf -C b001::1 -W 50
+EOF
+```
+
+This will run the client with a fixed window of 50 interests.
+
+#### Using hicn-light forwarder with hICN faces
+
+For sending hICN packets directly over the network, using hicn faces, change the configuration of the two forwarders and restart them.
+
+##### Server Configuration
+
+```bash
+server$ mkdir -p ${HICN_ROOT}/etc
+server$ LOCAL_IP="9001::1"
+server$ cat << EOF > ${HICN_ROOT}/etc/hicn-light.conf
+add listener hicn lst 0::0
+add punting lst b001::/16
+add listener hicn list0 ${LOCAL_IP}
+EOF
+```
+
+#### Client Configuration
+
+```bash
+client$ mkdir -p ${HICN_ROOT}/etc
+client$ LOCAL_IP="9001::2"
+client$ REMOTE_IP="9001::1"
+client$ cat << EOF > ${HICN_ROOT}/etc/hicn-light.conf
+add listener hicn lst 0::0
+add punting lst b001::/16
+add listener hicn list0 ${LOCAL_IP}
+add connection hicn conn0 ${REMOTE_IP} ${LOCAL_IP}
+add route conn0 b001::/16 1
+EOF
+```
+
+### vpp based hicn-plugin
+
+Compile the hicn stack enabling the [vpp](https://github.com/FDio/vpp) support.
+
+In this example we will do a local hiperf client-server communication.
+
+```bash
+$ curl -s https://packagecloud.io/install/repositories/fdio/release/script.deb.sh | sudo bash
+$ apt-get install -y git \
+                    cmake \
+                    build-essential \
+                    libasio-dev \
+                    libcurl4-openssl-dev \
+                    libparc-dev \
+                    vpp libvppinfra vpp-plugin-core vpp-dev python3-ply python python-ply \
+                    --no-install-recommends
+
+$ mkdir hicn-suite && cd hicn-suite
+$ git clone https://github.com/FDio/hicn hicn-src
+$ mkdir hicn-build && cd hicn-build
+$ cmake ../hicn-src -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr -DBUILD_APPS=ON -DBUILD_HICNPLUGIN=ON
+$ sudo make -j 4 install
+$ export HICN_ROOT=${PWD}/../hicn-install
+```
+
+Make sure vpp is running:
+
+```bash
+$ sudo systemctl restart vpp
+```
+
+Run the hicn-plugin:
+
+```bash
+$ vppctl hicn control start
+```
+
+Run hiperf server:
+
+```bash
+$ hiperf -S b001::/64
+```
+
+Run hiperf client:
+
+```bash
+$ hiperf -C b001::1 -W 300
 ```
