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. Uh.... I give up. -- TTFN, patrick
