What internet isn't these days? My current 25Mbit DSL link goes to a box a few hundred meters down the street and then to a shared fiber link back to Bell. They are all "up to" some speed. > So you could be sharing your 2.5Gb with up to 100 other people and if > everybody decides to download a few hundred GB of video files at the same > time you could be seeing speeds like 25Mb. > So last mile bit rate is almost always much greater than the bandwidth that > is available from the end node(home) to the core(151 front). > I have seen 6Mbit DSL reduced to hundreds of bps by chronic back-haul > congestion. > > So a fiber/cable modems buffering with a 1Gb output may be enough to cover > the practical bandwidth available on a reasonably loaded network. My understanding is that the shared part is at least 10Gbit for each segment. Not sure how many houses would share one segment. I still expect a fiber connection to be faster than my 25Mbit DSL connection. And it's not like people are constantly downloading, so I would think for the most part you ought to get decent speed in most cases, although of course what speed the server at the other and can provide you is a different story. It's only as fast as the slowest link. -- Len Sorensen --- Post to this mailing list [email protected] Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
