  1. Huh? on Why Are T1 Lines Still Expensive? · · Score: 3, Insightful

    Well, I'm certainly no expert when it comes to "real" Internet access such as T1 connections, etc.

    But, my understanding was (and someone please correct me if I am wrong) that a T1 line is a dedicated connection: The telcos create a complete, unimpeded circuit, point-to-point, from where you are, to wherever you are paying to have it terminate (generally at your ISP).

    If "where you are" happens not to be serviced by fiber, then they have to dedicate a pair of copper wires to you: That removes a physical pair of wires, along the entire pathway of the T1 circuit from where you are, to where it terminates, for so far as is necessary to do so.

    And, I suppose, even if you have fiber servicing where you are, somewhere along the way they still have to provision that bandwidth, to dedicate it to you, and again that removes part of their capacity from "general" use.

    Compare and contrast that to DSL and Cable broadband access: They both *share* bandwidth: For DSL, it's shared on the phone line, for Cable, it's shared on the cable connection.

    But, in neither of the latter 2 cases, is any of the upstream bandwidth dedicated exclusively to your use, in either direction.

    THAT is what you are paying for, for a T1 line, etc. - dedicated symmetrical bandwidth: For a T1 line, you get 1.54 Mbps, in BOTH directions, guaranteed.

    And again, that's my poor understanding of this.

    As much as I hate car analogies, here's one that is close, I think: Consider the current road systems, in any particular country. You have a combination of local roads, that link to freeways, highways, etc.

    When you get a dedicated circuit, such as a T1 line, you are paying for a "road", from where you are, to your ISP, one which has no other "cars" on it, except for those that YOU put on the road. At some point, that "road", merges onto a "highway", and then YOU are then paying the "road provider" for the privilege of a dedicated "lane": They are blocking off a section of their "highway" to make a "lane" for YOUR use, only, and in doing so, they are removing it from general use.

    And, that "lane" is "two-way", BTW: The "cars" that travel from where you are, do so at full speed, without "stop lights", etc. - and when they return, they return in the same way.

    And that's why T1 lines are still "so expensive" - though their cost HAS dropped, and remarkably so, considering.

    Oh, and yes, the analogy breaks down, past the point where the "lane" meets the ISP... so?

    "slip and fall in the shower is a more frequent cause of death for teens than online predators"

    Note the lack of citations: iamacat doesn't cite ANYTHING to support this. It's a bald appeal to emotion... an opinion stated as fact - VERY nice, very smooth!

    Finally, this: "Did you also install a bathroom cam?"

    This is the final appeal to emotion that put iamacat's post over the top, here on Slashdot, to +5, Insightful, I think... it has the appeal to emotion, with just enough insinuation towards perversion against those that would disagree, to do so.

    All without ever actually saying what was implied: "You know, statistically, your teenager is more likely to slip, fall, and die, in the shower, than be a victim of an online predator, and I think that you should install a camera in your shower so as to monitor that, too". Stated as such, it would be derided for lack of evidence, and paranoia, and an invasion of privacy... not to mention the fact that installing a camera into the bathroom wouldn't actually PREVENT someone from slipping and falling in the shower.

    But, stated as iamacat did, it's a masterful piece of innuendo, much beloved here on Slashdot these days.

    It was modded up, I bet, because it sounds good, appeals to the prejudices of the masses here now, and is stated in an easily consumed IM format: That is to say, one line of response text, which seems to be the unit of posting/attention here now.

    There were no Ethernet switches, back then, you see - the only way to minimize collisions on any particular Ethernet network segment was to keep the collision domains small.

    But, later, I used switches to eliminate collisions on Ethernet networks, just as everyone does today. It eliminates collisions by ensuring that any frames that would have collided, by timing, do not, by buffering them, and passing them very quickly to their destinations, because the switches have processors that are actively mitigating collision issues - that's what they do, after all. But, switches effectively mitgate, eliminate or minimize a problem that cannot exist in token-passing networks.

    And, in that sense, token-based networks scale better as node population per segment increases.

    I never had to deal with Token Ring - as I said, we used ARCNET, which was token-based, but was NOT IBM's Token Ring, so, I never ran into issues such as you describe, where the token was lost: ARCNET handles such differently. As I recall, with ARCNET, there's a timeout value for the token: The node to which it is passed must respond with an ack to the passing node, within that time, and if it doesn't, the entire segment resets - the node that last passed the token issues a reconfigure (recon) broadcast on the segment, and then the token gets regenerated, and the new token is given to the lowest-numbered node on the segment, to start over... which is why I always addressed the NetWare servers' ARCNET cards at node ID 1 - if a station failed "out there"... there would be no noticable loss in performance, you see.

    "On a server I have that sees plenty of network traffic over switched ethernet, I still have '0' in the interface's collision column."

    But, it wouldn't, nor shouldn't, so long as the switches are doing their job - that's the point, right?

    You shouldn't worry yourself over my post: I was talking about networking from a historical perspective which you'll never see.

After all, all it takes is a small amount of knowledge, and a broadband connection. It's not as if you actually have to understand how BitTorrent works, for example, to use it.

    I have many issues with the current state of copyright in the US, and have just as many issues with what I deem to be price gouging.

    For example: I'd love to own the original Star Trek series on DVD, as it was something I watched on TV when I was very young, and owning them and being able to watch them at my leisure as I wish is something that appeals to me. Buying them is well within my means now, but I refuse to do so: I believe that they are overpriced, and think that Paramount is simply being greedy by charging what they do for them. I just checked again, and the price for all 3 seasons, new, is $265.99 US on Amazon.com. (yeah, yeah, I can probably get it cheaper elsewhere, but, no offense - my time is very precious to me... and I prefer to deal with Amazon as it's a "one-stop" place for everything that I want - the prices may not be the lowest, but the service is great, availability generally the same... and for $72 per year, I get 2-day shipping on anything I buy via Amazon... and if you think that THAT is a rip-off, consider this: It works out to $6/month, to get anything I want in 2 days, availability permitting. I've ordered FAR MORE than enough, to offset that cost, in books, CDs and DVDs, in the past few months alone, had I paid for 2-day shipping because I was unwilling to wait the amount of time it takes for it to arrive at the free shipping rate. And, yes, I'm self-indulgent - so? I'm willing to pay for it, and it is worth it to me at $6/month).

    Despite that, I'm not tempted to download them illegally: I've too much self-esteem to do so. Instead, I've chosen to look into other SF series that are available now. Firefly is on its way to me as I type this, it will be here tomorrow. I've not seen any of the episodes, but heard many so good things about them that I bought it. $29.99 US, 2 day shipping for free. Seems worth it to me. The first season of the new Battlestar Galactica will be here later this week.

    I guess the difference between me and so many others here is this: I don't think that over-pricing by a corporation for their copyrighted materials entitles me to obtain them illegally - it's not worth my self-respect, and I'm not so lacking in the same to think that self-entertainment is more important.

    Were I *so* offended by, for example, Paramount's pricing of ST:TOS, I'd take the time to write them, and explain my position to them, NOT in any hope that they'd change their minds, but simply to voice my opinion. As it is, I think that they're stupid, and greedy, and they won't get my money... but I STILL refuse to obtain them illegally, although it would be a simple matter to do so. Maybe I'll write them a letter, maybe not.

    But, I don't need to be entertained so badly, via their products, so as to break the law to do so, regardless of perceived "provocation" that would "justify" it.
