It looks like the massive uptake in QUIC is largely due to Google and Facebook, per Bart's presentation. One of the biggest obstacles to broader adoption is the increased CPU cost (due to lack of NIC TLS / GSO offload support from the vendors) so it's interesting that as the vendor representative, he brought this up.<p>I'm curious how Cisco is getting these measurements, since if the proportion of YT traffic is accurate, then the overall internet bandwidth is much larger than I thought it was.
