Hi,
I have been using DPDK (under 2.1) with a single DPDK fastpath process, however now I want to interface with another legacy user-space application that is able to accept ethernet packets, what is the recommended/best performance approach to relay/share packets back-forth between my DPDK application and this legacy application ?
I want to avoid turning my legacy application into a complete DPDK application if possible.
Thanks in advance for your help.
Regards,-Mansoor

Hi,
I think multi-process example is one of the easiest way for your purpose.
Though the legacy application should link with the DPDK library, the
legacy application just use the resources what your DPDK application
already setup. I think the ring and mbuf/mpool are everything the
legacy application have to aware.
Regards
Chaeyong
May the Fun with you.
