Probably preaching to the choir here but there are a lot more costs than that involved. It's all right having the bandwidth at transit points, but you've got to be able to get the bandwidth to the customers locations. With no idea of what Comcast's distribution is like for all we know the graph could be one transit point in one area of the country and indicative of poor localised behaviour rather than centralised. Virgin Media were notorious in various cities in the UK for over-saturating the local network. Out in the towns and smaller cities you'd be okay and have no problem saturating a 20Mb line, but often whole areas of London, Manchester and the like would suffer high latency, packet loss and so on during 'peak' hours because they would over sell their infrastructure (12am-10am fine, then steadily worse until unusable come the evening). They only seemed to add more capacity to the areas when enough people complained.According to: http://en.wikipedia.org/wiki/Comcast "Comcast has 15.930 million high-speed internet customers" If a 10G port for transit is paid by comcast $30/Mbit/s monthly that's 0.19 cent/internet customer/month for a new 10G port to properly desaturate this particular link. Did I compute something wrong? LaurentAssuming that I did my math right. It's actually 1.9 cents/month/per customer. Assuming they pay $30/meg...
IMO two network graphs are next to useless out of context. Paul
