Beyond RX/TX CPU affinity, in DANOS you can further tune power consumption by changing the adaptive polling rate. It doesn’t, per the survey, "keep utilization at 100% regardless of packet activity.” Adaptive polling changes in DPDK optimize for tradeoffs between power consumption, latency/jit

For the open source version we replaced our proprietary routing protocol stack with FRR. Since the AT&T acquisition we have also added support for a few merchant silicon platforms in a hybrid software/hardware forwarding plane. ONIE images are available from the same link. Cheers, Robert.
