    Well, it has to be fixed in every device. And it shouldn't be this way, some devices shouldn't be buffering nearly as much as they are. The bottom line here is that every device maker that thought it would be a good feature didn't evaluate the idea in light of every other maker doing the same thing. So we have buffers everywhere stopping up traffic and causing this problem.

    And you may have updated your router the other day, but be assured that unless you are using something open-source AND you went in and configured it just so, you have not changed anything about this problem with your hardware. The makers are not yet into this.

    No.

    Packet losses would be handled by adjusting to the conditions.

    Look at the trace Gettys posted in the referenced article. Lots of dup packets. Get rid of those, and there's some bandwidth that can be *used*. And allowing TCP to adjust to prevailing conditions should result in less packet loss. It might seem to be less bandwidth also, but we may be in a vicious circle of increasing bandwidth to solve a problem that is NOT bandwidth. Packet loss by itself is a symptom, not a problem.

  8. Re:It will be a hack on Bufferbloat — the Submarine That's Sinking the Net · · Score: 1

    Actually, the solution to bufferbloat is to stop using large buffers. Let TCP manage the connection.

    An analogy. If you want to drip irrigate your garden, you usually connect the water source, add in the necessary stuff, and eventually you put a drip emitter on the line that only lets 1GPH flow, or whatever. Now, if you put a 1GPH valve on the water connection, fine, you get the 1GPH at the emitter. Add emitters, cause you have more than one flower in your garden, and well your flowers are sharing the 1GPH. Not what you intended. Bufferbloat has all these devices trying to manage the flow, and they are all breaking at the least the initial management, your TCP stack. And breaking all the others as well.

    Another, better analogy. If you've ever been going down a long street and hitting every red light, that's an intentional traffic management method (unless the lights really aren't sychronized, which happens). This allows intersecting traffic to flow also, and prevents accidents. Now imagine this on the Interstate, on a divided highway. There is no intersecting traffic, only on-and off-ramps. But some nimrod put up a light to buffer you all so that traffic would accumulate, than be released to maximize the flow. Wrong. It just creates artificial congestion. Bogus.

    I'm obviously not very good at this, but I grok what Gettys is saying, in my reptilian-part of my brain.

  9. Re:pegged connection == latency, who'd of thunk it on Bufferbloat — the Submarine That's Sinking the Net · · Score: 1

    As I understand it, the problem is:

    - Under max load, your connection slows to much less than is possible.

    - Restarting the transfer doesn't solve the problem.

    - Testing with anything less than that max load doesn't reveal a problem. Indeed, testing just latency or bandwidth doesn't show a problem.

    - In some cases, the connection 'lopes', I think, starting out at full speed and then getting throttled for NO GOOD REASON except that the buffers have defeated normal TCP bandwidth management.

    - The cause can be anywhere along the system.

    - Buffers sound good, but in practice are essentially defeating TCP throughput management features.

    Why is this bad?

    - As we hurdle headlong into a cloud-based environment, we will be sending more and larger transfers. This 'bufferbloat' will get worse, and we risk the hardware makers responding by including BIGGER buffers. Making the problem worse and worse.

    - Other protocols such as VOIP, various video, etc. will be significantly impacted, and it will get worse no better unless the hardware makers understand this and both test and modify their designs as needed.

    - With the large number of routers out there, this is a big $$$ investment overall. Adopting IPv6 may help by flushing out old routers, if the makers again understand and both test and modify their designs.

    - And this seems to affect virtually every type of device, from home routers and smartphones/3-4G networks to 'big-iron' routers and switches. Collectively, this has become a serious problem.

    So, in a nutshell, when you start up a download of your new favorite ISO, and the connection slows to a trickle, this might be caused just by 'bufferbloat'. When your video goes to hell halfway through the show, this might be caused just by 'bufferbloat'. When your Skype goes to hell regularly, this might be caused just by 'bufferbloat'.

    I'm wondering how much this impacts my pet peeve, waiting for a page to load and seeing it is just the damned ads holding it up. And ads are getting bigger and heavier every day.

    Gettys was dead-on when he mentioned that in the 'old days', a T-1 was pretty snappy. I had a T-1 at work for a long time, and it was great in the mid 90s. Even my 128k ISDN line was plenty enough for serious surfing, which back then wasn't quite as deanding as now, but even Flash sites were just fine. Now I have a 20MB cable connection and it just seems slow, even when I adjust for expectations.

    Obviously, I blame this 'bufferbloat' for my inability to prevail in COD.

    The occasional EW mishap is legendary, fleeting, and cautionary. Everything from NASA to AT&T has been hit by this. British telecom has a few stories to tell, as well as most of Europe. Darned pods go off at the drop of a wrench.

    But this is definitely NOT something that's been around since the 60s. We think of EW traditionally as an anti-radar weapon, until we realized that jamming communicaitons from the radar to the launch control trailer was just as effective at neutralizing SAM threats. Still problems with various IR-guided shoulder- and vehicle-launched weapons, but there you go to infrared and that's a whole 'nother area of specialization.

    So jamming comm means you risk jamming your own, since most militaries have observed treaties and kept to certain bands, except in wartime when they surely don't much care. This means you have to have frequency-agile systems that can be adapted to battle regimes where you don't much care what bands you're on. Since trying to communicate on frequencies that are already in use is difficult, you go to either less-used freqs, or hop around finding spots that are not in use, if only for a few seconds.

    BLADE seems focused on essentially determining if transmissions are: 1)not friendly, 2)not benign, and 3)suspicious.

    "Not friendly" is fairly easy to determine if you have enough theater information to know what your own forces are using. This will not always be the case, so this is as difficult a problem as any other.

    "Not benign" will be a lot more interesting. It's probably just as important to know what is innocuous as it it so know what is "suspicious".

    I'm a little surprised that BLADE isn't more obviously intertwined with battlefield comm intelligence. Not very useful to jam your own comm. But if we can communicate with Voyager 2, we can certainly burn through the clutter and keep comm going in a busy battlefield environment.

    It's sometimes more useful to listen to your adversary than it is to prevent their communications. But BLADE might be destined to be an offensive weapon. Imagine how D-day might have gone if the Allies had been able to completely deny communications from France to Germany. Of how Vietnam might have gone if we had eliminated the North's ability to communicate electronically, at all. Something as simple as docking a cargo ship or dispatching trains could turn into a quagmire. Yes, you can jam landline telephones. No, it isn't pretty. The collateral damage includes civilian deaths from loss of emergency response and hospital communications. You can be sure that both Iraq campaigns used these tactics, at least selectively.

The idea of hiding an aircraft carrier is almost as interesting in being able to frustrate your enemy's communications so well that they end up screaming in plaintext. Ah, modern warfare. Some day we'll start a war campaign by convincing the enemy to order 3 million Pampers instead of 3 million pairs of boots. Then we'll tell them "Look! Ponies!"
