Hi DPDK Users/devs
Can you please tell me the benefits of using DPDK over openonload for
solarflare cards?

Hi Ankit,
(May be users@dpdk.org is a better place for such questions)
OpenOnload provides a user-level TCP/IP stack with POSIX interface –
transparently runs any Linux sockets binary without requiring any
changes to the application. "DPDK is a set of libraries and drivers for
fast packet processing. [snip] DPDK is not a networking stack" (quotes
from dpdk.org). So they have very different end use-cases.
So if end-use case is performing packet processing and/or switching
packets between network interfaces then DPDK allows an open API to be
used. However, if app needs to terminate TCP or UDP flows then
OpenOnload provides a mature TCP/IP stack. We’ve seen good results with
applications such as Nginx with OpenOnload.
Regards,
Andrew.

Hi Andrew
I'm developing a kit for kernel bypass purpose.OpenOnLoad already provides
a way to do kernel bypass.
Can dpdk also be used for kernel bypassing purpose on intel/solarflare
cards?
