Earlier quoted context omitted.

netflix last year was reported at 37% in NA, so I suspect it will continue to be a contender as it gets more traction globally. http://appleinsider.com/articles/16/01/20/netflix-boasts-37-... 'peak download internet traffic' whatever that means.

Traffic during peak hours. Peak demand is what really matters for infrastructure.

"one out of four bytes that are delivered to end users across the Internet originate from Google" Such a mind blowing statement. Wonder when (if) they'll hit one-in-three bytes.

What's mind blowing is that despite all that, they're still at the mercy of Comcast, Verizon, and at&t.

I guess if Netflix ever switched from AWS to Google Cloud Platform...

99% of Netflix bytes are largely served from Netflix's own CDN + a cadre of third party CDNs. The bytes to/from AWS isn't trivial by itself but relatively negligible compared to video traffic.

I don't know, feels like a massive waste of resources and if Google is doing it simply because it can. It's probably much cheaper for everyone else to handle latency/throughput problems on the client side and application level, sticking to all the traditional networking, but not relying on it for quality. Even in the web browser we already can send all kinds of asynchronous requests to multiple servers in multiple da…

From the description, it sounds like the routers have been reduced to more simple muxers, where a small tag added to the packet determines which port it goes over instead of trying to make a complicated decision all in one focal point.

This has pushed the decision back from the routers to the servers, where it scales with the number of hosts handling connections and can additionally be determined per /session/ instead of per packet. That state is held where sessions already need to be stored anyway instead of being duplicated in a router where it's entirely a burden.

Can someone ELI5 the difference between this and https://azure.microsoft.com/en-us/services/expressroute/ ? Is the technology principle the same?

ExpressRoute is just Azure's version of AWS VPC. They're complicated VPNs for cloud services.

Espresso is a system for controlling BGP peering using application-fed metrics. It's basically complicated source routing.

> But running a fast, efficient, hyperscale network for internal datacenters is not sufficient for a good user experience

It will never be sufficient. A good backbone infrastructure doesn't compensate for the fact that the majority of users don't have ISP choices especially for fast speed fixed/mobile networks.

Right, I expect that the Netflix traffic numbers are for the last-mile only (CDN to customer). Google's numbers should be from a 1e100.net server to the customer across multiple networks (unless Youtube has some localized CDNs, which would complicate the math).

Every vendor is moving to SDN and hardware is getting more and more generalized with more functions crammed into smaller die space. Google is just using its massive cash reserves and R&D capability to beat the vendors to the punch. They probably expect network vendors to go this way, and want to eventually sell these new routers as a service to customers the way they did with their search boxes. There's also the little problem of routers facing an ever-bigger internet and not getting any more efficient, so planning for the future means having better scaling routers.
