WTF is going on with Cablevision?

Comcast Loves Packet Manipulation

PowerBoost really fudges the numbers. Comcast customers see above 100% of the advertised speeds *on speed tests*

Yes, OOL is not what it used to be. I remember back in 2001 when 10/1 speeds were the envy of everyone.

Re: Comcast Loves Packet Manipulation

Actually, they are pretty careful to take such shaping into account in the measurement:

The test is over 30 seconds of full rate, with three concurrent TCP streams. The bandwidth delivered is only measured in the last 5 seconds.

(There is also reporting on the first 5 seconds, which captures the boost effect).

Read the report a bit more. That data is for sustained speeds and taken after the Powerboost effect. If you add PowerBoost back in they exceed Fiber as much as 150% (130%-200% over provisioned speed for upload)

I totally agree with you! When I saw Comcast over 100% I thought it's a joke! There is no way Comcast is delivering over 100%!!

Re: Cablevision

I am one of the test subjects with SamKnows router on CV's network.
I had CV install Docsis3 modem and ever since then my speeds have been advertised 15/2 any time of the day, any day of the week.
It's the vast majority of Docsis2 modems that still suffer during peak hours.

Satellite

These guys keep insisting on calling satellite broadband so how come thier numbers are not up there for the embarrasment of those companies. I have to admit that Hughesnet has corrected that problem by and large with speeds usually at or above plan speeds on the new systems but those stuck on the old systems and some or most on Wildblue have speeds in the toilet. If your gonna call it broadband and insist it is the best way to reach some people then it should be included in these reports.

Fairpoint?

Why isn't Fairpoint in there? Are they below 50% or something?

Interesting to see how many Cablevision subs

Cablevision looks way out of the norm . My guess is that sample size had to be out of wack for CV.

Now my isp, Windstream they just suck all the time so no suprise in their numbers and yes I have one of those SamKnows routers.

They were pretty lucky to get special measurement / reporting (unlike U-verse and DOCSIS3.) I expect Verizon will play this up as an ISP vs the select/limited areas that FiOS is available.

FCC commisioners should get 80% of their pay

I like how report takes the tone that 80% of what you pay for is ok.

Must be nice to live in markets where Time Warner actually invests money into their infrastructure. I don't know anybody in my area that receives 90% of their download speeds from 8pm to 10pm.

At my last apartment I was lucky to get 3mbps during those hours on my 10/1 connection.

Comcast fudges speed tests

My downloading over the past 24 hours on Comcast. Only once did it spike over what I pay for. Of course I get 25mbps consistently on speed tests but the real speeds I get are about 40-50% of what I actually pay for (the dark black line in the image).

Re: Fairpoint?

They probably didn't have too many people with Fairpoint to be able to give results. I think SamKnows/The FCC was looking for a large test subject for particular ISPs.

Re: Comcast fudges speed tests

than i must be the lucky one with TWC.
i paid for 15/1 RR turbo, always more than 15.. most of the time over 20 mb down.. mid night around 4 am i got power boost to 40 mb down sometimes...

How are you downloading/testing? Single stream, multi-stream, etc.... TCP and distance will impact your speed measurements.

Also this data looks like 5 min averages vs actual speeds

Not to mention taking what is clearly bursty traffic and diluting it down to 5 minute averages for the graphs.

Actual / promise ration and FiOS

Some people write that they don't get the actual/promised ratio as given in the report. Remember, the report uses a large database and an individual experience may vary from it. From Qwest VDSL, I get consistent upload / download speed >92 % of the advertised speed with a latency of 24 ms. Qwest's statistics in this report are far worse than that.

What struck me in this report is the superior performance of Verizon FiOS. Will some one educate me, why FiOS is far superior to other technologies ?.

I am waiting for a day when Fiber-to-home internet comes to Boulder, CO.

Re: Comcast Loves Packet Manipulation

comcast customers see above 100% because they over-provision. standard 12/2 is actually 13.2/2.2.

ALL going down hill

I noticed 1 thing ALL of them have in common (not so mcuh Verizon FIOS)..... They ALL are going down.

This either suggest 1 or 2 things.

1) Major American ISP's services are becoming poor. Through lack of development and over taxed networks.

Which would be ironic since ALL of them have been raising their rates 2,3, sometimes 4x a year in the name of wanting to improve their services.

2) Something I have always suspected, but never could prove.... When you 1st sign up, you are given priority network access. And once you "get use to" having their services. They figure you'll be less likely to switch and will settle for less and / or will not notice.

80% is okay for a "best effort" service, especially when overhead is taken into account. If you want 100%, you're welcome to pay for a line with an SLA, at approximately 100 times the price.

Indeed - the facts do show otherwise. These results ran tests on end points that SamKnows and the FCC controlled, to M-Labs servers. There were 1,109 test units in our network. The average peak period and 24-hour sustained (i.e. without PowerBoost) speeds met or exceeded advertised speeds - both upstream and downstream. This is on page 15 of the FCC report.

The numbers with PowerBoost are on page 20 and 21 of the report. One of our tiers achieved 152% of the advertised download speeds, and all were over 100%. In the upstream, one of the tiers delivers over 220%. On a related note, the recent ShaperProbe paper shows similar data, and demonstrates how regularly PowerBoost is delivered.

They are all going down from where? This is the first study.

Boost technology thresholds vary from provider to provider. It is IMPOSSIBLE for them to adjust for it and get meaningful data. The only way to work around it would be to test each time for an extended period of time attempt to detect the drop then start the benchmark...a very difficult task. Not only are the speeds skewed but also the consistency of service. In the case of consistency or QoS anyone using boost technology would have their connection QoS poorer than someone not using boost technology.

This is pretty much why this whole thing is waste of time because virtually all the majors are now using some form of boost technology on one or more tier offerings.
