said by Oh_No:There's obviously a communications breakdown between the two of us. First, average is average. It's not difficult to calculate. Second, I did not suggest any predictable utility with a simple average.
Well if you keep making stupid statements it will keep getting worse.
Really you need to do some statistics reading and learn what "in control" means before you say there is a real average that can be used for any reasonable prediction.
said by Oh_No:No they have not. Everything is oversold, has been from the beginning, and will continue to be. Your issue now appears to be with capping, which is not how I read your previous posts.
People have been paying for that from about 1995 to about 2011
said by Oh_No:When did I defend caps in response to managing congestion?
Then why are you defending caps????
While it is true that all networks are oversold (and always will be), it's not as bad as you think it is.
100Gbps is not a lot of aggregate backbone capacity anymore. It's not atypical for even a mid-sized hosting provider (e.g. FDC Servers) to purchase multiple 10Gbps links. While there are a lot of ways to measure aggregate bandwidth in a complex routed network, it's fair to say that Comcast's customers can pull well more than 100Gbps total from the network, especially if you include CDNs that peer directly with Comcast.
You are right in that Oh_No is completely unrealistic in believing that a consumer-level broadband network could be provided without any over-subscription. If we assume that the average provisioned bandwidth is 15Mbps, then Comcast would need over 250 Tbps of aggregate bandwidth, which is well beyond the capabilities of even the largest broadband providers today.
said by powerob :I don't know Comcast's bandwidth capacity or peering arrangements, nor do I really care. It was a purely hypothetical suggestion to make a point with Oh_No ...that I apparently failed with. Thank you for adding a little sensibility to the discussion.
