they suggest that Akamai and other ISP-side caching is either not affecting these numbers and their pertinence to the "backbone" at all, or not much.
This is from a Sandvine press release. Sandvine measures traffic at the last mile, so it doesn't really know whether a Netflix stream is coming from a local caching server within the carrier's LAN, from a caching server that is peering with the carrier, or via the real internet.
In the case of a large ISP with a Netflix cache server accessible locally, (either in-house, or via peering at a local carrier hotel), the traffic doesn't really travel on the internet.
Since when is peering not part of the Internet? Since when is even on-net caches not part of the Internet? I always thought if I am on the Internet, anything I ping is "on the Internet". (I am intentionally ignoring things like split tunnel VPN nodes.) Perhaps you think of the "Internet" as the "tier ones" or something?
But for smaller ISPs, the traffic will travel on the internet between the nearest cache server and their facilities.
I guess you assume smaller ISPs don't peer? Unfortunately, reality disagrees with you, 100s if not 1000s of times. Still confused about this whole notion, though. Perhaps you can clarify?
Because of caching, the load on the actual internet won't increase as much as the amoount streamed onto last mile infrastructure.
