And before anyone accuses me of sounding overly critical towards the AU ISP's, let me point out that we've dropped the ball in a major way here in the United States, as well.We've dropped the ball in any place where the broadband architecture is to backhaul IP packets from the site where DSL or cable lines are concentrated, into an ISP's PoP. This means that P2P packets between users at the same concentration site, are forced to trombone back and forth over the same congested circuits. And P2P is the main way to reduce the overall load that video places on the Internet.
Michael - I don't think this is the case for most NA cable operators. P2P between subscribers in the same general area simply hairpins back over the HFC from the aggregation hub (location of the CMTS), no unnecessary backhaul to another distant PoP location. Now, the rest of the traffic will be aggregated further up on its way towards upstream peering...but that is a different traffic flow. -ron This E-mail and any of its attachments may contain Time Warner Cable proprietary information, which is privileged, confidential, or subject to copyright belonging to Time Warner Cable.
