dpdkadapter
-----------
Intel® DPDK is a set of software libraries and Ethernet drivers (native and virtualized) that run in
Linux user space to boost packet processing throughput on Intel® architecture.
DPDKAdapter is a static C++ library that uses DPDK library and provides the following capabilities to an external application through its simple API:
Transmit streams of packets in a line rate according to a chosen scheme and timing requirements;
Capture Ethernet traffic on a line rate.
Dpdkadapter is used for support Intel® DPDK for Ostinato, with all its functionality preserved.
Why DPDK provides considerable speed improvements
- Allows avoiding latency while copying through kernel space
- Allows avoiding using Linux scheduler and bind thread to CPU core
- No threads synchronization
Ostinato is an open-source, cross-platform network packet crafter/traffic generator and analyzer. Craft and send packets of several streams with different protocols at different rates.
Steps to use Ostinato with DPDK adapter:
1. Download DPDK by link:
http://dpdk.org/browse/dpdk/tag/?id=v1.7.0
Put it in main "Ostinato DPDK" folder, folder name should be dpdk-1.7.0.
2. Modify the following dpdk file to compile it properly:
dpdk-1.7.0/config/common_linuxapp
CONFIG_RTE_BUILD_SHARED_LIB=y # Compile to share library
CONFIG_RTE_BUILD_COMBINE_LIBS=y # Combine to one single library
3. Build dpdkadapter:
cd path/to/ostinato_dpdk_repo/dpdkadapter
# run script sudo ./custom_setup.sh <interface_list>
sudo ./custom_setup.sh eth1 eth2
make
4. Ostinato dependencies should be met on system, for more details please refer Ostinato manual:
sudo apt-get install qt4-dev-tools protobuf-compiler libprotobuf-dev libpcap-dev mercurial
5. Build Ostinato:
cd path/to/ostinato_dpdk_repo
qmake
make
Run Ostinato server uses DPDKAdapter:
- sudo ./path/to/ostinato_dpdk_repo/start.sh
