DPDK itself only provides raw access to network, which means there is
no TCP/IP protocol stack. DPDK only deals with layer 2, not IP protocols
directly.

There have been several other projects using
DPDK which provide network protocols such as the TLDK (part of FD.io).

To understand what DPDK does read documentation and look at the examples.

Hi Stephen,
Thanks for your info.

I need few more information's.
My dpdk system is directly connected to internet.
I want to know about this system only based on IP.

Here I can see an example is creating an interface (Kernel NIC Inteface
sample).
Using this and I can configure IP and I can reach this system from outer
world right.
will this have any performance issues?
