Comcast conducting Blufferboat trials

[url=http://www.dslreports.com/forum/r30381722-CustSvc-Bufferbloat-Trial-Seeking-Volunteer-Testers][/url]Bufferbloat Trial: Seeking Volunteer Testers
You may have heard of “bufferbloat”, an industry-wide issue that potentially impacts performance for millions of Internet users around the globe. We’re excited to try out a solution that may address the issue, not just for our customers, but also for Internet users everywhere. We would love to have your help trying it out. [Image: smile.gif]

We are seeking a (very) limited number of participants for a technical trial in which we will test techniques for mitigating bufferbloat and improving performance.

Bufferbloat causes increased latency in modems (as well as other network equipment and operating system software). Data typically is set in a queue in your modem in order to deliver it more efficiently. Increasing the buffer size within a modem – as many modem manufacturers have done in recent years – increases the amount of information a modem can process, but also can cause more data to be stored in a queue, resulting in increased latency. For latency-sensitive applications like gaming or Web surfing, this can cause an unintended degradation in performance. Bufferbloat mitigation techniques involve adjusting a modem’s buffer size to optimize the balance between capacity usage and latency. More information from 3rd party Internet researchers is available at http://www.bufferbloat.net

Although the CableLabs DOCSIS 3.1 specifications include support for dynamic queue management, DOCSIS 3.1 modems are not yet deployed in customers’ homes. This trial will focus on static queue management in the upstream direction, using a specific DOCSIS 3.0 modem. Participants must be current Comcast customers subscribed to Comcast’s High Speed Internet service. Test equipment, a splitter, and a coaxial cable will be provided to participants for the duration of the trial. The trial will take place entirely on this dedicated equipment and over a separate Internet connection from a participant’s current Internet connection. It should not affect your normal Internet use and will not count against any usage thresholds that may apply.

If interested, please send an e-mail to bufferbloat@hsdtrials.comcast.net. Be sure to include your name, service address, and account number if you have that handy.

Thanks!

Just got my Blufferboat test modem today.

Getting over 90MB down and 10MB up. Nice to watch videos without any hicupping. Downloads of updates are just about instant.

How's the LATE-ncy?

Worse than before what?

Here is a link to the results from Ookla Speedtest http://www.speedtest.net/my-result/4864739571

Before you lost your virginity... no, before you tried out this test modem. ;P

Well now I know they are throttling my connection ever since moved in here. Charging me for 75MB service but have never seen higher than 20MB. Video has never played well.

For a better bufferbloat test (especially before/after your new modem) you can try http://dslreports.com/speedtest

It measures latency *during* transfers, which is when bufferbloat kills you. (The other speed tests seem only to measure latency when the line is idle, where you'd expect it to be good.)

That's how I found out about the trial was from Karl at DSLreports.

Cool, interesting.

Soon, we'd be seeing 500Mb/s speeds for the same price as 75Mbps today. 

What do you think about this tech and the latency - is it really much worse?
