I have always felt that this issue has been overcomplicated. It seems what this really stems from is the classic ISP business model. From a pure network design standpoint, nearly every network has an uplink that is not large enough to sustain simultaneous high usage from most, or all, of its devices. Your classic endpoint data closet example would be a 48-port switch with 1Gbps access ports, and a 10-20Gbps uplink. This problem seems much worse in the ISP world. Many years ago, ISPs could easily oversell their connection. Realistically only worrying about the small percentage of extreme users downloading high volumes of data via Usenet, BitTorrent, or other file sharing services. Life for an ISP was probably pretty great. Now, with the sheer number of households streaming video, it seems to be apparent that ISPs are drastically overselling their connections. It does not even make logical sense to blame a single service if an ISPs upstream connection is saturated. If the ISP did not oversubscribe their connections at such ridiculous rates, this would not be an issue. Why does it matter that a single service is causing the largest portion of the traffic congestion? Netflix recommends a 5Mbps connection to stream HD video. Most all devices today would stream at HD quality, if possible. How is it that an ISP such as Comcast doesn’t have the uplink capacity to sustain many users at a mere 5Mbps? I find it absurd that multiple ISPs are overselling their connection to the point where a speed of 1/7 of the average connection in the USA is too much of a strain. It really seems that the level of oversubscription is equivalent to having a data closet with a 48-port 100Mbps switch uplinked at 2Gbps . The whole situation just stinks of pure greed. |
