[OOR-Devel] AF_XDP

[Lori Jakab]

Hi OOR developers,

I just became aware of something called AF_XDP in the Linux kernel, which
is a technology to allow faster zero-copy transfer of network packets to
user space, with hooks to BPF for packet modification. See more information
here:

https://fosdem.org/2018/schedule/event/af_xdp/ (this link has slides and
video recording of the FOSDEM talk)

>From the OOR perspective, this could potentially be a solution to improve
performance in a self-contained way, without relying on a kernel module
(like in the early days of LISPmob), or external dependencies like DPDK or
VPP.

I'm not saying that this is a priority, just that it's something that we
should be aware of.

HTH,
-Lori
