Modern routers are unable to do line-rate regardless of packet size. See for example the Q100 ASIC from Cisco. Rated for 10.8 Tbps, it is only able to achieve 6 Bpps [1]. So it needs 200-byte packets to hit line-rate. However, as for Netflix, this is not problem since they only push big packets.

- kkielhofner 4y agoWow, I've been out of this space for a while! Last I was paying close attention to any of this 10G ports were new. Glad I learned something from my old life today! I stand corrected on "always line rate all the time in any circumstance" but by your math and my general point < 1 Tbps from one of these appliances across multiple 100G ports isn't problematic in the least from a hardware standpoint - especially for the Netflix traffic pattern with relatively full (if not max MTU) packets.
