POFSwitch-dpdk is developed base on the original POFSwitch which you can find at www.poforwarding.org. It performs much better than the original one. Please download and have a try!

This guide is based on the following system environment:

• Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-100-generic x86_64)
• gcc version: gcc-4.9.real (Ubuntu 4.9.4-2ubuntu1~14.04.1) 4.9.4
• CPU：Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
• Network Interface Card：Intel 82580 or I350

git clone https://github.com/USTC-INFINITELAB/POFSwitch-dpdk.git
git clone https://github.com/USTC-INFINITELAB/dpdk-2.2.0.git

Add two environment variables of your POFSwitch-dpdk and dpdk-2.2.0 source codes locations:

export POFSW_ROOT=~/POFSwitch-dpdk
export DPDK_ROOT=~/dpdk-2.2.0

Check the value of CONFIG_RTE_BUILD_SHARED_LIB and CONFIG_RTE_BUILD_COMBINE_LIBS in $DPDK_ROOT/config/common_linuxapp, make sure they are both set to y.

#
# Compile to share library
#
CONFIG_RTE_BUILD_SHARED_LIB=y
#
# Combine to one single library
#
CONFIG_RTE_BUILD_COMBINE_LIBS=y

Install the DPDK environment, run:

cd $POFSW_ROOT
./dpdk_setup.sh
# configure the DPDK hugepages
root$ echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
root$ exit

Wait for a few seconds, input the number of NICs and the NICs' name you want to bind according to the hints:

cd $POFSW_ROOT
./setup.sh

You can start the POFSwitch-dpdk:

sudo pofswitch -i [CONTROLLER_IPADDR] -D -c [COREMASK] -n [NUM]

• -D: This command parameter specifies the POFSwitch to use DPDK.
• -c: An hexadecimal bit mask of the cores to run on. Note that core numbering can change between platforms and should be determined beforehand.
• -n: Number of memory channels per processor socket.

The details of the POFSwitch command parameters you can find at https://github.com/USTC-INFINITELAB/POFSwitch/blob/master/README.md.

For example, start a POFSwitch-dpdk to connect to a POFController at 192.168.109.120 and specify to use 4 cores, run:

sudo pofswitch -i 192.168.109.120 -D -c f -n 4
