I'm paying for transit through Sprint. I'm paying a nominal flat-rate to hold up my share of the facilities for my connection into PCH, and I'm not paying anything to any of the other PCH members. PCH maintains a no-settlement peering policy by not having members do transit across it... To use the example above, Mainstreet advertizes a route to themeselves and to their customers to all the other PCH peers, but they don't advertize a route to Net99 or Aimnet. Likewise, I advertize routes to my customers, but not to Sprint. Thus any traffic I have for any PCH peers or their customers goes directly to them, but anything to anyone who's not a PCH peer goes out through my paid-transit connection. So what we'd like to do is peer with larger ISPs. We know that individually we're small-fry, and that we'd never stand a chance of getting Sprint, MCI, etc. to join on the same basis as little ISPs, but collectively we can put one router on MAE West and potentially one on the S.F. NAP. What we'd like to do is offer up all our routes together on that router for peering with other ISPs at the MAE, but since we'd still be smaller than most of them, even banded together, we'd offer to give up transit (i.e. if MCI agreed to peer with us there, we'd agree never to dump traffic _through_ MCI to MAE East; we'd only use MCI to reach MCI's customers) in exchange for a no-settlement peering agreement, just as we use among ourselves. Why this is _should_ be attractive to larger ISPs :-) is that it means they themselves should actually have to carry less traffic. If they choose to peer with us, they can dump traffic directly into each of us via PCH. If they don't peer with us, they have to use a transit carrier (Sprint to reach me, or Net99 to reach Mainstreet, in the example above) and pay a settlement to that carrier. So is anybody up for it, or am I another one of those raving loonies that make mailing lists so annoying? -Bill Woodcock ________________________________________________________________________________ bill woodcock woody () zocalo net woody () applelink apple com user () host domain com
