Re: [p2pi] Follow-Up from Comcast Presentation

[Richard Bennett <[e-mail]>]

I think the point is that the Internet's traffic model only works if the first-hop network handled most of the congestion and the core is relatively uncongested. That's because congestion management mitigates overload at the source, and the fewer hops the load travels before back-pressure is applied, the more efficient the use of network resources. Reading RFCs 896 and 970 and this remark by John Nagle on Slashdot may help:

Maybe I've just been plain lucky.  Comcast in my area (AT&T Broadband, TCI prior to that) have been excellent. 

Do we have any data to work with about this congestion?  (I feel like I'm back to the subject of my paper.)  How bad? How prolonged?  And since the ISPs control the product parameters -- the sizes of the shared pools of bandwidth, the number of consumers who share it, the prices of admission, and the size of the pipes between a subscriber and the shared pool -- does the technical community generally accept that this as a business problem or a technical problem?
