Congestion and Latency : Not the same thing

First rule: You can run at 95% load, and still not experience any excess latency. Latency only becomes an issue what you are at 100% load, and you are dropping packets.

Second rule: You can experience latency with no congestion. If your router is messed up, if your layer 1 connection is fubar, you can experience latency. Even if you are using the 64 byte ping, you can get latency due to hardware problems, poor router or a host of other issues.

Third rule : QOS helps with congestion. QOS does NOT HELP with latency. Period. Read up on internet 2 for a REAL WORLD example of a long term, major project that relied on QOS. Bottom line is : They dropped QOS, and added more bandwidth, because that was the correct technical solution.

Final rule : If comcast can get away with it, comcast will do it. The Ellacoya switch box that comcast is testing, SPECIFICALLY ALLOWS you to manually add latency to traffic. If you pull up the management interface to configure it, you can deny, throttle or delay a protocol. Comcast has much to gain, and little to lose by doing this. Past history of corporate misdeeds are good predictors of future misdeeds. However, proving it is much harder to do. To test it, the correct test would be to do a VoIP strictly within your node, to see if latency occurs. Then try the exact same call over an SSL link, which is not subject to throttling/etc of the ellacoya box. If it works over SSL, and doesn't work without SSL, then there's a damn good argument that comcast is deliberately treating the protocols differently. If it sucks over SSL too, then there's a damn good argument it's not comcast.

And here comes the BS. Like you would even know if they are testing those out, which from what I've heard, they aren't. There are few Canadian ISPs using them.

Quote your source please!

·Comcast

maybe his source is him so what you are reading is not hearsay, maybe he actually provisioned the switch

it is not only Vonage that is experiencing problems with Comcast. Comcast is number one ISP source of issues for CallVantage. You want sources? No you don't. 4AM conf. calls on Sunday are no fun.

All, I love hearing the rantings of someone whose never touched one. Unless you happen to work for a certain wireless ISP out there, then I KNOW you haven't used one.

Simple enough test: What language is used to interactively program the switch? If you've used one, you'll know off the top of your head (and how buggy it is).

If you knew anything about the e30, which I highly doubt you do, you would KNOW that the VQR is specifically designed to mess with VoIP. In fact, to save you from frothing too much at the mouth, I'll post one of the public documents. Of course, if you have access to a customer login, you can pull up the complete documentation, which specifically shows you what I'm talking about, but like most of your rants, your just pulling words out of your ass.

Summary : You're still a ranting clueless weirdo

And your point is?

Comcast isn't testing these for use.

You can post what you wish by spitting out words and acronyms that you've read on their site, that doesn't prove that you've used their equipment either.

Comcast is the #1 ISP which also leads people to understand that they are the largest target and are going to have the most people complaining in one concentrated area.

Did he provision the switch? HAH! Right - tell me another funny. I don't think ANYONE knows what he does, other that come up with statements on how bad America is and how he is opressed. Oh, and maybe tie dying more shirts for his next march on capitol hill. However, since Comcast doens't have much in NY, I doubt he really works for the company - especially when he hates the "evil corporation" so badly. What I do think is that he spends most of his day on the internet googling comcast and jumps from one related story to the next and draws conclusions on some sort of forumula on what he reads, things, and has been brainwashed by Howard Dean, that is if Dean isn't too conservative for his taste. He seems to know everything about every subject out there - no, wait, he just takes a topic, appends "evil corporatio" to the end of his thought and he's got it down! But I digress.

Comcast and Call vantage... there is a bit of a relationship around there you know. I've, in my hand, about 3 official corporate memo's about Call Vantage and AT&T.

Do you not, for a second, think that some of the problems that people on Comcast (or any other service for that matter) are those issues that are born from the subscriber them self? the fact they may not be hooking the service up correctly? or maybe that Vonage may be having the issue? (No, can't be that, Vonage at $24.00 a month is perfect! )

If you are anyone that handles problems that customers have directly in any part you will know that many of the so-called ISP's issue is really that of a subscriber that is doing something wrong on their end. (Now, for the small minded people that can't read - this doesn't say that ALL problems are customers, but MANY of them ARE)

Additionally, people who think that a residential internet service is going to run flawless, without issue, and up 24/7 without a glitch is a fool for them self. Not even corporate networks or networks deemed mission critical don't have problems. The difference is that MC networks get fixed faster - for every minute a MC network or service is down, MUCH $$ can be lost. A residential service is hardly MC nor is it a corporate or commercial grade network.

I know many people across the US that are on Comcast and have Vonage ad their main phone service (against my advice) and don't have any problems using the service. I also have vonage, as a 3rd provider, and it's on Comcast and don't have issues using it at all.

I guess the story should state that Comcast is picking on a few select people. Reading the article alone, if one can read past their own hatred, bias, and suspicious beliefs, will see that these reports of problems from all over are most likely issues outside direct Comcast influence. There are also many people across the Comcast footprint that have Vonage and AT&T services and DON'T have problems just the same.

Not much in NY?? Go do a WhoIs on any Comcast IP. THEY ARE BASED OUT OF CHERRY HILL, NJ. Wow.

Because you know for sure... Funny thing is wasn't it you that blew up on someone for making statements they couldn't prove. If I were to take an educated guess, i would almost say you work for those turds.

NY and NJ are not the same place. Comcast is based in Philadelphia and yes they do serve portions of NJ. NY has predominantly Cablevision and Time Warner Cable.

I've done it before and will continue to do so. Do some searching, you will not find anything that proves that Comcast is using any Ellacoya equipment.

Says the "anonymous" Vonage troll.

Imrf, he's not an anonymous troll any more, he's a registered troll now.

He is also one that doesn't get that Vonage has inherit issue alone. My inbound vonage calls don't even terminate at the TAD, rather, they are sent direct to my land line using call forwarding so the calls don't even touch my Comcast or Qwest internet connection. With that in mind, I have periods of times/calls that sound like India call center calls. But then again, Vonage is perfect and all calls sound good. It's the ISP that causes the quality issues.

Tell me, when the call never touches Comcast, my isp, why do some calls STILL sounds like garbage, echo, delay, or sound like they are under water or motor-board?

He thinks its "the isp" - I say it's just the fact that Vonage can't control the quality of their calls over the public internet.
