Actually the digram is not fully accurate in that it gives a flat as opposed to heirachical/ overlay view.
What it omits is that Internet traffic goes to a Broadband Remote Aggregation server (at which authentication, authorization & accouting takes place). That node is actually an IP level node in per region, and from there it goes over IP to an internet peering/ transit node which can be local or international. The diagram needs to distinguish between the IP layer (Internet layer) and the transmssion (fiber/ ME) layer, as it inaccurately conflates the two.
