Hi Nick,
At work, we’ve been experimenting with user-space networking stacks using
rumpkernels in conjunction with DPDK on top of Intel processors/networking
hardware. The area’s we’ve been using it the most are related to
high-availability application routing (e.g. layer 7) and network failover.
We employ the NetBSD networking stack made available as a rumpkernel library,
to take the network traffic from DPDK and turn it into something coherent.
Being able to build the rumpkernel components into our projects and
develop/test/profile/tune in userspace has made life a ton easier. It’s also
made easier to make material modifications to the networking stack (e.g.
exposing kernel internals) to suit specific applications.
