The number listed on the letter is the standard 800 Business Class line. This is so ridiculous.

the executive support people face penalties for having open tickets so they just close them unresolved. unbelievably frustrating.

Yes, at this point, I am assuming that is the hold up. That or I heard a rumor of a "forklift" of Cisco equipment to be replaced by an "A" vendor (assuming Arris). Either way, sounds like it's going to be like this for months yet, and I wish they'd just provide a rough ETA. But then their customers would know it's not operating properly and then they'd have to shell out credits. Luckily for me I logged a call as soon as I noticed this problem and I will be sure to request some sort of compensation for this.

a rough ETA wouldn't be any good anyway, they already provided one for ipv6 on cisco and that came and went.

pflog posted : I happened upon this extremely informative paper:

»groups.csail.mit.edu/ana/Publica···auer.pdf

It discusses capped vs. uncapped powerboost, the history and possible motivations for it, and more importantly how the token buckets work.

Until recently the amount of buffering for best effort traffic was static and fairly large. Recent revisions of the DOCSIS specification have introduced a buffer control parameter that can be used to match the amount of buffering to the subscription speed tier and Powerboost configuration.

I am guessing those of us seeing the seesaw pattern are on a CMTS which either a) cannot be configured properly for capped PB or b) is misconfigured (perhaps still implementing uncapped PB in one token buffer but not the other?) causing a disagreement between the token buckets and therefor the "harsh" discarding of packets which manifests as throttling instead of shaping. I'm ignorant to all this stuff, but after reading that paper it sure sounds to me like some CMTS's either do not support or are not properly configured for capped PB.

*edit* The references for the Capped Peak traffic rate vs. MSTR are in this:

»www.cablelabs.com/specifications···1206.pdf

All kinds of stuff way over my head :)

Although this certainly sounds like it could be related:

When a CMTS implements both a Maximum Sustained Traffic Rate and a Peak Downstream Traffic Rate for a
service flow, it limits the bytes forwarded in any interval T to the lesser of Max(T) defined in equation (1) of Annex
C.2.2.5.2 and Peak(T) defined in equation (2). The peak rate parameter P is intended to be configured to be greater
than or equal to the Maximum Sustained Rate R of equation (1). Operation when the peak rate P is configured to be
less than the Maximum Sustained Rate R is CMTS vendor-specific.

When the CMTS enforces the Downstream Peak Traffic Rate, it SHOULD "rate shape" the downstream traffic by
delaying the forwarding of packets until the Downstream Peak Rate expression (2) can be met. The specific
algorithm for enforcing this parameter, with or without concurrently enforcing the Maximum Sustained Traffic Rate
parameter, is not mandated here. Any implementation which satisfies the normative requirements is conformant. In
particular, the granularity of enforcement and the minimum implemented value of this parameter are vendor
specific. The CMTS SHOULD support a granularity of at most 100 kbps.

So is this a case where my CMTS is "conformant", but lazy in the way it handles this, resulting in a non-smooth shaping? :huh:

I can achieve a nearly flat IO graph with this. So I can get by until they (hopefully) fix the sawtooth issue.

29700 (to kind of match the boot file parameter) didn't work out so well. The CMTS side buffering eventually ran out near the end of the download (341 MB). Makes me wonder how long 28500 and 27000 would remain consistent. I'll have to try a larger download.

pflog posted : My corporate escalations person REALLY is trying to help me. I know she is. I think her hands are tied because they're telling her "the boot file and CMTS check out".

So I spoke with her again tonight, and as an experiment we tried dropping me to the 17/3 profile. It is doing the exact same thing as the 27/7 profile (see attached).

What's even MORE interesting is that the powerboost is lasting almost exactly for the first 100MB of the file on the downstream side. PB lasted for ~40 seconds on this 17Mbps plan, whereas it lasted ~24 seconds for 27Mbps.

From JohnInSJ 's 17/3 IO graph, his powerboost is lasting for almost exactly 20s, about half what mine is.

I still think the CMTS isn't honoring the modem's boot file parameters, but I can't get anyone at Comcast to give this any serious inspection. :hmm:

Tech came out, fixed some loose fittings, a nicked cable, etc. But despite what he called a "better signal" and that he eliminated the ripples, the problem persisted (we both knew that would be the case).

He called someone who noticed a problem or "extra code" in the boot file or something. They removed that, pushed it to my modem and still no change. The tech couldn't do anything so they had to leave, which is why the ball is yet again back in the court with escalations (who want me to have yet another tech sent out :uhh:).

I suppose I should be happy I'm using FreeBSD. I plugged both my windows 7 work laptop and my wife's macbook pro directly into the modem and the throughput is even more erratic. Though perhaps their TCP stacks aren't tuned. I thought win7 and OSX 10.5+ had "auto-tuning" TCP stacks. :)

Right. The idea is this: I wouldn't have signed a two year agreement with my current speeds. I was incorrectly given the super fast tier during my 30-day window and was led to believe (by my install tech, phone reps, AND sales rep) that the fast speeds were normal and to be expected. That is not my fault.

I don't think that anyone in this thread has said that they were getting sustained speeds of 21/4 for the BC starter package. I have seen the word "consistent" used, but I suspect that applies to short on-line speed tests that also include at least some PowerBoost residue.

On all of the other tiers, it's always been less than 30 MB worth of downstream PB, and about 10 MB for up. With the uncapped PB throughput that I've been experiencing, those "buckets" run out in just a few seconds.

I ran large file transfers from Microsoft and consistently saw 7 MBps (not Mbps) through the whole download.

IMHO (and others'?), the "trial period" should accurately reflect the service I'm paying $2,000 for when I sign a two year contract. I can understand a slight decrease or heavy load times, but losing 80% of my speed because something wasn't set up right in the first place is not my fault. They have these gateways so locked down that I have no way of knowing, and my installation technician told me I could reasonably expect those high speeds. He said most Starter package folks got them, too.

pflog posted : PB aside, the 27/7 speed profile is jacked, and my speeds are anything but consistent after 'PB' ends. So no, that's not acceptable for a business class connection.

At least former 12/2 folks have consistent speeds after PB. 27/7 in some areas, not so much.

airwavz posted : Most of the posts / comments I've seen here and elsewhere on the net have said basically the same, and it certainly holds true for me as well (I'm on the 'now 16/3' Biz Class tier), but I'll take a consistent, dependable contracted speed over a BS powerboost speed - that only lasts a few seconds and degrades to a constantly varying up/down speed - any day of the week.

You did 'sign up for' - and agree to - the 'contracted' speeds, so you really can't complain about "losing" the speedboost 'bonus' that accomplished little anyway... I consistently saw 40 down-30 up speeds with powerboost, but running ShaperProbe or doing real file downloads always gave me 12/2 speeds before the 'upgrade' (with constant variations of speed on long transfers), so I'm OK with the increase, though I'd have been OK WITHOUT the price increase - :huh:

So in reality, speeds did NOT significantly decrease, they really did increase, but you lost the 'pretty numbers' you saw with Powerboost on typical speed tests - those numbers might impress the 'gamer crowd', but most of us true business users knew better all along.

mario02423 posted : Hey guys --

Has anyone else noticed that their speeds significantly decreased after Comcast rolled out the "free upgrade" (from 12/2 -> 16/4 or whatever) in October?

I went from 80+/30+ boosted speeds to exactly 21.19/4.01 (they don't go higher, ever).

So, I've called tech support about 10 times now, and the best I can get is "well, it's still higher than your contracted rate..."
They don't have the ability to "roll back" the configuration change on my gateway, and they won't bump up my tier because I got "extra" during the trial. Seems a bit shady. Adding insult to injury, this "increase" happened right after my trial ended. If my speeds had been like this during my trial, I certainly wouldn't have signed...

Let me know. Do you have similar issues? Have you talked to anyone about it? Have you gotten anywhere? I can't be the only one.

[EDIT] Adding that I posted in the Comcast Direct forum three days ago and haven't had a reply, and the Executive Response Unit representative has not returned my voice mails after her initial contact.

Thanks!
