Trying to steer anything the size of the Internet into a better direction is very slow and difficult at best. From the time changes in the upstream operating systems are complete to when consumers can buy new product is typically four years caused by the broken and insecure ecosystem in the embedded device market.

Market pull may do what push has not. But new commercial products are becoming increasingly available. I just ordered one of these for my house to see if it functions better than the SQM mitigation almost certainly notbut at least these should not require the manual tuning that SQM does.

Evenroute has been working hard to make the installation experience easy. DSL users seldom have enough bandwidth for the WiFi hop to be the bottleneck; so the WiFi work is much more important for Cable and fiber users at higher bandwidth than for DSL users stuck at low bandwidth. The Evenroute is therefore effective on all technologies, not just DSL. It is particularly important for DSL users, which suffer from sag more often than most, and the IQRouter is getting regular security updates and enhancements, which most home routers lack.

Router performance can be an issue on high end cable or fiber service. SQM itself is easy to configure. There is a very wide variety of home routers that can benefit from reflashing. Its web UI is tolerably decent, better than many commercial vendors I have seen.

WiFi chip vendors should take careful note of the stupendous improvements available in the Linux mac It will be interesting to see how long it takes them to pick up the stunning WiFi work.

Wireless mesh devices without bufferbloat reduction are particularly suspect and most likely to require manual RF engineering beyond most users. They require very high signal strength and transfer rates to avoid the worst of bufferbloat.

No one we know of has been working on minimizing transmit power to reduce interference between mesh nodes. So we are very skeptical of these products. Once burned, three times shy. That product therefore does not deserve a mention due to the behavior of the vendor.

We need to start some web pages to keep track of commercial products. This entry was posted on February 2, at am and is filed under NetworkingPuzzleBufferbloatSecurity.

But observed facts e. Some of the point solutions will actually require replacement of hardware, and time to research and engineer such hardware along with economics will often take time.

Does that mean we should do nothing? Of course not: we can immediately make the situation much better than it is, particularly for consumer home Internet service. And remember, your competitor will eventually beat you if you sit on your hands.

Gamers and others have been mitigating bufferbloat in broadband for years. Read on. Mitigating Broadband Bufferbloat in the Home Router. The best solution will be to remove the grossly bloated buffers properly, and not to have to hack around this problem in our home router.

Those are also technology dependent; and what can be done there is probably best taken up by the equipment vendors and standards bodies. As in many mitigations, they may come with costs. So when your network changes, you will need to repeat this process. You may not be so lucky with your ISP. That my test site is on a well run network at MIT, peering directly with Comcast has certainly made my life easier. More on the core Internet topic in the future. If it is customer replaceable e.

Many mid-range or high end home routers have traffic shaping features. You want one which lets you adjust bandwidth in both directions. Some commercial routers work really well, some less so. If so, please let me know. Facilities also exist in the open source router projects of various sorts, e.

More on this topic below. The WISEciti research project is also researching the behavior of home routers: if you have an old router, they may be interested in giving it a home.

We can try to avoid bufferbloat in the broadband device this by transmitting data to it slightly less fast than the broadband device will accept, and ensuring the router forwards data slightly less fast than the broadband device will transmit it.

Gamers have been doing this for years, as they are very latency sensitive and empirically discovered that limiting your bandwidth in this way will have good effects on observed latency.

Note you should do traffic shaping before you worry about classifying data e. I have no idea if these routers are usable for the following process. I presume not in the discussion below. In either case, you need the ability to perform traffic shaping.

Plug your router into the ethernet on broadband gear, or at worst, into the ethernet jack of your home router if that is included in your broadband service. I recommend monitoring your home connection via smokeping while you try this process.

Note the latency. Saturate the link in an upstream direction e.This topic has been closed to new posts due to inactivity.

We hope you'll join the conversation by posting to an open topic or starting a new one. Start a New Discussion. Here's a quick explanation of one of the most powerful features in the OS that powers our Nighthawk Pro Gaming routers, anti-buffer bloat.

What is anti-buffer bloat? Before we can answer that, we should answer what the heck is buffer bloat? Buffer bloat is a major cause of high lag in networks caused by excess buffering of packets or information. Bufferbloat can also cause packet delay or jitter, as well as reduce the overall network speed.

When a router is configured to use excessively large buffers like HD video or several streaming deviceseven very high-speed networks can become practically unusable for many interactive applications like voice over IP VoIPonline gaming, and even ordinary web surfing. Simply put, if you have a device or multiple devices like Google Chromecast, Amazon Firestick or smart TVs, the preloads for showing you a little bit of that movie or show is buffered.

All of those devices add up and start to vampire a little of your overall internet until things start to slow down. Anti-buffer bloat is designed to remedy this problem by reserving a percentage of your overall internet for interactive applications like VoIP and online gaming. That's correct. BufferBloat is when the traffic going through the modem overloads the modems buffer.

It is a big issue with the puma 6 chipset modems.

You can test for bufferbloat with DSLreport's speedtest. It is an issue that should be fixed with docsis 3. I just picked up an xr today and adjusted my bufferbloat settings in the xr according to the results the dslreports speedtest was giving me. Without the bufferbloat settings active in the router I was having the bufferbloat reading spiking into the red throughout the entire test. I was able to fine tune it to get about of my paid meg connection through without the bloat spiking to unacceptable levels.

I am working on getting my internet provider to assign me a docsis 3. Click here for our top support FAQs.

Also confused about traffic prioritization, how do you configure just for an Xbox? Message 3 of NetDuma Partner.If the tests below show high latency say, above 50 msecread our recommendations at What can I do about Bufferbloat.

The DSL Reports Speed Test makes accurate measurements of the download and upload speeds along with the latency during the test. Other speed test sites only measure latency when the link is idle - and that only tells part of the story. You can get numeric latency measurements with those other speed test sites if you run a ping test simultaneously.

To do this:. Watch the ping times while the speed test is running. If the times jump up when uploading or downloading, then your router is probably bloated. The suite of tests we developed to diagnose bufferbloat and other connectivity problems are good to 40GigE, but require the Flent RRUL test suite Using the Flent tools, it is possible to get a good feel for how the connection is behaving while you tune your settings.

Find us elsewhere.The hardware now available for Wi-Fi can accomplish tremendous performance, but it is hobbled by software designs that guarantee high latency under load.

We believe that the same sort of systems thinking that went on in the Bufferbloat Project can lead to performance improvements of an order of magnitude or more in Wi-Fi. As of earlywe have achieved many of these improvements, specifically a decrease of latency by at least an order of magnitude, with fair sharing of airtime across fast and slow devices.

Working software is available in the Linux kernel, as well as the OpenWrt firmware that runs on off-the-shelf routers, x86 boxes, and embedded systems. Ongoing work was discussed at the Linux network developers conference NetDev 2. The session was recorded and is available from the NetDev web site. WiFi may be the single most successful internet access technology. It is used by over a billion people.

Unregulated use has enabled an explosion of products and deployments using WiFi. Individuals can take immediate action as no network operator has to be asked to install or extend a WiFi network, and this contrasts strongly with centrally managed and deployed systems such as the cellular telephone based communications systems. One WiFi hop is between any company and a large fraction of its users; yet we have paid scant attention to how well WiFi functions, and nearly none at all at how it will continue to scale to the next million hotspots, and 10 billion new users and devices in the next 4 years.

WiFi downward compatibility constraints causes increasing complexity and problems with every succeeding generation of the technology. Toggle Navigation Bufferbloat.

I have read a fair number of postings in this forum about or around the topic of bufferbloat. They are either a year or two old, or no offense meant don't really know what they are talking about.

It is hard to perfectly cure bufferbloat, but it's straightforward to tune your settings to get Pretty Darned Close. If you're going to answer, "Tuning for bufferbloat is too hard, and nobody at Google could possibly figure it out without human intervention", then you probably don't actually know what you are talking about.

If you work on Google Wifi and think that, then please get in touch and I will help you see the light. If you are going to answer, "The only cure for bufferbloat is to buy a faster connection from your ISP", then you definitely don't know what you are talking about.

If you are going to answer that I should use wires between my Google Wifi nodes I agree and plan to, but that's not the question I am asking. Nest Wifi. Community content may not be verified or up-to-date. Learn more. Recommended Answer Recommended Answers 0.

All Replies 6. Recommended Answer. Bufferbloat is not a common issue that most will encounter. It only becomes a temporarly problem when your bandwidth is being consumed close to your maximum speed. Take a look carefully at the bufferfloat DSLreports site. Right below the test is a blantant ad for a router.
