How about if everyone just joins the BPP?

|Route-miles between cities might be the metric for determining the cost
|multiplier. Of course, this would assume some standard city-to-city
|mileage and a standard boundary, rather like a LATA boundary, that would
|make Santa Clara considered to be equivalent to a San Jose destination

|I think that we need some standard way to calculate such costs. Since we

|pricelist to their peers for city-to-city transit and use this pricelist.

|the rate per bit over that link.

|

|
|Same thing, too much variation, i.e. big aggregates and little ones.

|
|Agreed. This is likely going to require an industry council to come up

|suspiciously like regulated peering? Yes. It is regulated peering but my
|intention is for the providers to work out the regulations within the
|industry and only have government involvement on a review basis. For
|instance such a council would need to satisfy the government that it was
|not acting in an antitrust fashion and they would likely review this on a
|regular basis.

|
|I think that this suggestion addresses all sorts of asymmetry because I
|believe that the bottom line is that it costs more to transfer a given
|number of bits over a larger distance than a smaller one and that this
|cost can be quantified.
|

|
|I agree with this. However when I look ahead to a world in which the IP
|network is the only data communications infrastructure carrying voice,
|video, web, email, etc., then I think that the hard work must be done to
|create a scalable peering system. If we succeed at this then we will never
|have to go through the pain that the telephone network experienced with
|the forced AT&T government regulated monopoly followed by its forced
|dissolution still under government regulation. It is my opinion that the
|only way out from the specter of increased government regulation of the
|Internet is to pre-empt government action by working out a system that
|would be considered fair under existing antitrust laws. If we can go a
|significant way down the path to such a system, even if we have not yet
|implemented it, then I believe we will be able to secure support from the
|government for a self-regulated industry peering council.
|
|But that's just my opinion. I don't have all the answers.
