  1. Re:Stop the nonsense on A Layman's Guide To Bandwidth Pricing · · Score: 1

    If you're going to give us some B.S. about "building OC3's and I know personally these cost $xxxx/month and if you take the cost of that, and when you use your 20mb/s connection, you're costing the equivalent of $$$$ per month so it's a bargain..." you're merely showing your knowledge of how the internet worked in 1994.

    Screw OC3s, more like lots of OC192s. No OC768s though, overpriced especially on T640s. Afraid in 1994 I was on the Enterprise side of networking, not on the Service Provider side; so my '94 knowledge is more about Ethernet switching and Novell NOSes. Only moved to Service Provider Architecture in the last 3 years, so generally my knowledge is hopefully up to date, but maybe not.

    In 2009, you correctly note the transit bandwidth charges but these are not likely to be a significant cost to somebody like Comcast. Their bulk of their cost is *fixed* since it's the physical maintenance of their own network. The charges to connect to the backbone? Almost nothing compared with the fixed costs.

    They do have lots of Capital Expenditures to purchase all that gear on the edge and their metro networks. And if they're paying about 4-5% (for Cisco/Scientific Atlanta) of their actual costs after discounts for hardware/software/support maintenance (OpEx) on all that equipment, then that is a really large number. However, generally those numbers aren't too variable. They only have to upgrade when the peak averages increase. If the peaks just last longer each day but the absolute maxes do not increase, they're not spending more CapEx and thus no more OpEx. So the Transit BW costs are a pretty big part of what is costing them OIBDA dollars, and to top it off, their customers control whether they have to pay more one more month or not.

    Besides, if you look at TW's annual report, you'll see their cost for bandwidth is going down, despite bandwidth use going up from their subscribers.

    What does that tell you?

    That Level 3 is charging them less per Mbps now? Maybe $8? It can never be free. Maybe they get to Cogent pricing at $5/Mbps, but it will always cost money to run backbone networks for people who need transit. TWC (and other eyeball networks) will always pay for their transit. No one else is getting Settlement Free Peering.

    I know what it tells me. It says that if TW keeps at it, NYS should do their best to heavily tax TW's "bandwidth overage charges" so that there is no financial advantage for TW to charge people for additional bandwidth. It goes against my laisse-faire instincts of many decades, but these guys are crooks who lie with a straight face.

    No wonder people hate cable companies.

    I do not disagree that they are milking this. However I also believe that their highest profits come from the Cable TV side of the house. They don't have to upgrade capacity for that side of the house. Most folks just watch those broadcast channels and pay massive amounts for the pay subscription movie channels, again no real incremental costs, nearly pure profit once they have the infrastructure built out. For the less watched channels that aren't always broadcast, they don't even send the signal if no one is watching. If someone does start watching, they multicast those channels in case a second person down from the Head End starts watching. Again, once you get the first person watching, there are no additional costs, unlike when two people decide to download an episide of the Daily Show and start minutes apart from one another.

    Now if more and more folks all decide they don't need to pay for all of that TV and instead all want to watch The Daily Show as a download whenever they want to, then they are all getting those bits from a CDN server somewhere on the Internet. It is likely that TWC won't pay for transit to get to that CDN provider though. Comedy Central uses Akamai (at least from my Comcast home network) for their CDN. AKAM might have caches at e

  3. Not the way it works... on A Layman's Guide To Bandwidth Pricing · · Score: 4, Insightful

    Disappointed in the "research" that went into the original article. Most definitely if everyone didn't use any bandwidth for a day or two, then a cable company would likely pay less that month for the their transit bandwidth. In Time Warner Cable's case, they get their transit bandwidth from Level 3.

    I'd guess Time Warner Cable is paying about $10/mbps (or less) on the 95th percentile. So if the top 5% five-minute averages of traffic to Level is thrown out, then the top average left is what they pay for. I would bet there are a few samples each night that are in that top 5% of samples, if everyone did NOT use the Internet one night during peak, the sample that is left at the 95th percentile would likely be less and they'd pay less that month for transit charges.

  4. You've Agreed To It on Will ISP Web Content Filtering Continue To Grow? · · Score: 5, Informative

    Each person should review the Terms of Service (ToS) they accepted (and most likely continue accept each time they use their Internet connection) and look to see what is stated there. Also, realize that the ISP's will update it with nearly no notice. Inside of those agreements that you agree to generally through your use of their services you'll find all kinds of interesting things. For example, here is some relevant quotes from Verizon's ToS in Section 14.4:

    "You hereby consent to Verizon's monitoring of your Internet connection and network performance, and the access to and adjustment of your computer settings, as they relate to the Service, Software, or other services, which we may offer from time to time."

    Who is to say that "adjustment of your computer settings" doesn't include adjustment of .html files being delivered to you. Oh and just in case that wasn't strong enough, in Section 15.8 you get:

    "15.8 You agree that Verizon assumes no responsibility for the accuracy, integrity, quality completeness, usefulness or value of any Content, data, documents, graphics, images, information, advice, or opinion contained in any emails, message boards, chat rooms or community services, or in any other public services, and does not endorse any advice or opinion contained therein. Verizon does not monitor or control such services, although we reserve the right to do so. Verizon may take any action we deem appropriate, in our sole discretion, to maintain the high quality of our Service and to protect others and ourselves."

    Similar allowances are inComcast's Acceptable Use Policy. Basically, folks have to understand what they are signing up for and how often it can change.

    There are companies out there today, Phorm for example, who already are working with ISPs around the world in order to put their gear in the ISP networks to create targeting advertising based on all Internet habits, not just specific sites with specific cookies or the like.

They must be desperate for the controversy that her articles cause, because I really see no value in them after reading a couple of them this morning. The worst article , and the one in question, tries to paint quite the negative picture of Pamela Jones' sanity and lifestyle. Instead it leaves me questioning O'Gara's ethics and sanity. Quite the smear campaign on the part of O'Gara.

    So, Pamela Jones could perhaps be a 61-year old Jehovah's Witness who lives in a not so nice apartment. What does that have to do with anything? O'Gara finishes the article hinting that perhaps it is all stolen identity, though she didn't present a news story that would lead you to that conclusion.

    I spent the first 23 years of my life as a Jehovah's Witness. I do not believe I am scarred in anyway because of it. If anything, I think I have a lot more respect for my fellow human beings and in general have a deep desire to be a good person. Sure the methodology of learning about the religion is a bit like brainwashing, but they have their religious beliefs like most religions. They just are more strict about the belief and the punishment if one does constantly violates them. If you are going to have faith, I think most religious people would appreciate the JW's strictness.

    Did the religion make me paranoid? No. Does it take a lot of your time? Yes, but if you are going to devote your life to being religious then it probably should take a lot of time. Personally I appreciated science too much to put so much faith in religion. I still believe that if any religion has it right though, it is probably the JW's. They read the bible and do what it says. They refuse to pick up arms against another human, they punish sinners through disfellowshipping (total cut off until they have repented of their sins), and they make worship the primary thing in their life not allowing anything else to come first. There are obviously more devoted JW's than others, but that is true of any religion.

    So, after reading the crap that passes for journalism from O'Gara, I personally can't wait to see her unemployed. Perhaps she can go get a job at the National Inquirer.

  23. Redundant Networks for Patient Care on Hospital Brought Down by Networking Glitch · · Score: 2, Informative

    I spent three years (1995-1998) at Perot Systems as a consultant designing and implementing hospital networks for Tenet Healthcare (2nd largest hospital chain in the US). There was at least one hospital that had the budget and the foresight to see that reliance on the network would do nothing but increase.

    For that hospital, my network design was one that incorporated as much redundancy as possible at the time. For each patient care area, such as nurse's stations and ancillary areas such as radiology, cardiology, surgical theaters, etc. it was decided that each of the two network jacks would terminate in seperate closets. This meant doubling the number of closets required in order to meet distance limitations, but the hospital had already started working on allocating that space for the closets. Also for any important ancillary areas such as the lab, central supply, there also was two seperate networks. For the server farms theirselves, the Patient Care systems all had redundant connections to the primary and backup networks as well.

    As each wall jack terminated into a different closet, each closet had two seperate networks as well. Each closet would house the primary network for half of the jacks served, and the backup network for the other half of the jacks served. The fiber paths from each closet took disparate paths back to seperate data center rooms, one external to the main building of the campus and one inside the main building. At the time layer 3 switches, or switch routers such as the Foundry Big Irons, or Cisco 6500s were not available. So as much as I dislike using Spanning Tree, I had used it at the time. All priorities were manually set though so there was no doubt where the root was and where it would move to in case of failure.

    So, the switches terminated on another switch which was partitioned to several segments. Switch connections were made between the two data center as well. Each segment had a connection to a Cisco 7507 Fast Ethernet port local to that computer room, and another in the second computer room. Forming the core were two sets of two Cisco 7507s. In order to prevent one OSPF network from affecting the other OSPF network static routes were used (would use BGP if I had to do it over again). Outside WAN connections were terminated redundantly on the two patient care networks as well.

    While the primary network in the hospital also supported the non-patient care areas (such as administration, the backup network was only for the patient care areas. That was just to prevent the type of thing that happened in the article, where something non-patient care related ends up taking everything down.

    Reverting to backup paper systems would be nearly impossible once the "tube" systems were sealed up. Much like the movie Brazil, hospitals used to have pneumatic tubes running all over the place, especially between the lab and the nurse stations. Running samples and results back and forth would definately introduce a LOT of delay for a doctor trying to make a life and death decision.

    I am sure that I would I design things different these days (for one, Layer 3 would go all the way to every single edge switch and collapse on a fast switch router) but I think the design probably held together well. I should check back in someday and see how long and well it lasted, if they did replace it.
