> You could go the DPDK route but that has downsides of your application needing exclusive access to the network interface. Never did it, but I guess you could reroute traffic you don't care about to the Linux network stack for regular routing. https://doc.dpdk.org/guides-16.07/howto/flow_bifurcation.html https://doc.dpdk.org/guides-16.07/howto/flow_bifurcation.htm... Not sure that's a realistic scenario though. You rarely expose a DPDK app directly on a regular / open subnet. You often have a dedicated app, with a dedicated NIC, on a dedicated subnet, for a dedicated traffic.
