Outlook for DPDK multi-process support

[Lukáš Šišmiš]

Hello all,


I'd like to ask you about future outlook of multi-process support in 
DPDK (https://doc.dpdk.org/guides/prog_guide/multi_proc_support.html).

On DPDK Userspace 2022, I have presented a solution that uses 
multi-process support (https://youtu.be/TtiR74w3Yv4) in Suricata IDS.

But after the talk, some people have reached out to me and suggested 
that multi-process support might not be supported in the long-term.

As I would like to continue developing the concept further, I thought it 
might be a good idea to consult the idea and possibly open the discussion.


As an alternative solution to multi-process support I see either 
vhost-user/virtio/vDPA or VF. However, I couldn't find any performance 
benchmarks on this topic.

Further guidance is highly appreciated.

Thank you all in advance.


Best regards,

Lukas Sismis
