Re: [net] 60/5?
said by chrispix  :Many people (adults) with the high speed could probably use it to (as some one else posted) connect to their work VPN's just as fast as being in the office. Immagine being able to work from home just as if you were in the office. It might make telecommuting more plausable. Anyway, some other people certainly host websites/VOIP etc on there. Playing games, downloading patches (i.e. windows service packs!) Think how big the Service packs will be for Vista! You can do that right now. Comcast 8 Mbps/768 kbps.

said by SuperG03 :This is a very recent map of the North American Internet backbone, including 134,855 routers, colored by telecom company (Verizon, AT&T, Qwest, Level 3, Sprint Nextel, cable companies, smaller players). See Attachment. Interesting but unless I'm missing something I don't see any link speeds on this diagram which is where I thought this thread tangent had gone (how fast are the internet backbone links).
I did some googling around and for long-haul links I couldn't find anything faster than OC-192 as being used although current information on the big player's networks seems to be hard to come by.
This article: »www.qwest.com/about/media/pressr···,00.html from June 2000 says they did a 400 mile OC-768 test and "Qwest expects to begin widespread deployment of OC-768 technology in the first quarter of 2001" but from their latest network map it doesn't appear to have happened.
Does anyone know if there is a technical limitation that keeps existing long-haul fiber links from being upgraded to OC-768 or is just an issue with the cost of upgrading the hardware can't be justified yet? |

00000 | I read that OC-768 is just too expensive, in comparison to just bundleing multiple OC-192s together. |

said by Vamp :that would be dumb and useless, it's probably really hard to find servers to even max 30mbit. If they were going to add a faster package it should be like 30/8 or 30/10 or something. a lowly p-2 350 can stuff FE and a lowly p-4 can stuff a GE. It's not hard to biuld a box that can keep those kind of connections full.

Just because there's an OC-768 card, I doubt there's a router out there yet that could forward that many packets.
Juniper and Cisco might have a switch that could support a single card, but then there would be no redundancy. Long distance GBIC's are probably not available at that speed yet.
As said, trunked oc192's are much cheaper and offer redundancy. Now, I wouldn't be surprised if all that changes by next year. |

It's not the computational power that is the problem, most websites simply cannot afford hosting fast enough to max a 30 Mb connection times however many users are hitting the site all at once. |

It's not the computational power that is the problem, most websites simply cannot afford hosting fast enough to max a 30 Mb connection times however many users are hitting the site all at once. most websites are hosted on shared server with many other accounts. Just because you don't see over a megabit per page does not mean the server can't do it. There's tons of things that will reduce the amount of data you see and that is mainly compression. http compresses very well. Have you every actually administered a webserver? I have and i actually am getting ready to put another one into production. i can guarantee you a p-2 350 can easily keep a FE pipe stuffed and a p-4 1.4 ghz or faster(AMD athlon 1ghz or faster box) can easily keep a GE port stuffed if enough users hit it at once. If the files you are sending aren't html files(mp3's, movies, streaming files) then you don't need nearly as many users to have the server stuff the pipe.

| What I'm really getting at would be websites hosting large files. When you have video, audio, and other data files that are several hundred megabytes each, and you have hundreds of users pegging the server trying to get anywhere from 3 Mb to 15 Mb each, you're CPU would be very underutilized, but the bandwidth would simply be gone.
For general web browsing, I agree that you can easily compress pages and there is not much of a problem. However, even at that, some sites get slashdotted and everyone knows how that goes.
So it looks like we are basically agreeing that you don't need a lot of CPU power to max a pipe; most websites out there just don't have a wide enough pipe to handle the bandwidth demand. |

I supposedly have that from Comcast, but its like a rocket sled with no turning. the quality of service of the connection sucks in Ellicott City, MD due to Comcast screwing up their routers for anything that requires a constant connection, like gaming.
one of the techs at my place in trying to resolve my QOS issues told me about how the digital signal is bleeding over on the broadband and affecting QOS on the broadband. I bitch, but no resolve. I can't wait for FIOS in my area. |
