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?
