Comcast Accused of Congestion By Choice
An anonymous reader writes "A kind soul known as Backdoor Santa has posted graphs purportedly showing traffic through TATA, one of Comcast's transit providers. The graphs of throughput for a day and month, respectively, show that Comcast chooses to run congested links rather than buy more capacity. Keeping their links full may ensure that content providers must pay to colocate within Comcast's network. The graphs also show a traffic ratio far from 1:1, which has implications for the validity of its arguments with Level (3) last month."
Ever wonder what Comcast's connections to the Internet look like? In the tradition of WikiLeaks, someone stumbled upon these graphs of their TATA links. For reference, TATA is the only other IP transit provider to Comcast after Level (3). Comcast is a customer of TATA and pays them to provide them with access to the Internet.

Notice how those graphs flat-line at the top? That's because they're completely full for most of the day. If you were a Comcast customer attempting to stream Netflix via this connection, the movie would be completely unwatchable. This is how Comcast operates: They intentionally run their IP transit links so full that Content Providers have no other choice but to pay them (Comcast) for access. If you don't pay Comcast, your bits wont make it to their destination. Though they wont openly say that to anyone, the content providers who attempt to push bits towards their customers know it. Comcast customers however have no idea that they're being held hostage in order to extort money from content.
Another thing to notice is the ratio of inbound versus outbound. Since Comcast is primarily a broadband access network provider, they're going to have millions of eyeballs (users) downloading content. Comcast claims that a good network maintains a 1:1 with them, but that's simply not possible unless you had Comcast and another broadband access network talking to each other. In the attached graphs you can see the ratio is more along the lines of 5:1, which Comcast was complaining about with Level (3). The reality is that the ratio argument is bogus. Broadband access networks are naturally pull-heavy and it's being used as an excuse to call foul of Level (3) and other content heavy networks. But this shoulnd't surprise anyone, the ratio argument has been used for over a decade by many of the large telephone companies as an excuse to deny peering requests. Guess where most of Comcasts senior network executive people came from? Sprint and AT&T. Welcome to the new monopoly of the 21st century.
If you think the above graph is just a bad day or maybe a one off? Let us look at a 30 day graph...

Comcast needs to be truthful with its customers, regulators and the public in general. The Level (3) incident only highlights the fact that Comcast is pinching content and backbone providers to force them to pay for uncongested access to Comcast customers. Otherwise, there's no way to send traffic to Comcast customers via the other paths on the Internet without hitting congested links.
Remember that this is not TATA's fault, Comcast is a CUSTOMER of TATA. TATA cannot force Comcast to upgrade its links, Comcast elects to simply not purchase enough capacity and lets them run full. When Comcast demanded that Level (3) pay them, the only choice Level (3) had was to give in or have its traffic (such as Netflix) routed via the congested TATA links. If Level (3) didn't agree to pay, that means Netflix and large portions of the Internet
Am utterly shocked that anybody could be so cruel as to suspect a poor innocent cable company of trying to protect their cash-cow video delivery business by deliberately sucking at being an ISP(harder than they do simply by nature, that is) and using their oligopolistic incumbent position to shake down nimbler and more responsive competitors.
What makes Backdoor Santa think this is done to drive service providers to Comcast? Occam's razor has a much simpler explanation: Comcast doesn't want to spend more money upgrading their capacity.
Hell, if I was a service provider I wouldn't consider Comcast after seeing those charts, not with that bad service.

Great post, AC.
You however omitted the graph that most excellently summarizes this entry, here it is for your readers.

Anyone who is offended at the behavior of these ISPs could join http://www.stopthecap.com/ It may be futile, but at least it's better than whining.
Please someone tell me that Verizon is better, because I really want to switch to FIOS when it's available.
Does Comcast simply not care about their customer satisfaction ratings, or are they on a quest to consciously plunge their ratings into the gutter? I ask semi-seriously because the latter strategy has merit: they can effectively do whatever they want without fear of too much consequence. After all, if they still have customers after kicking them around like this with the crap they've been pulling, they can probably continue to treat their customers like dirt and get away with it.

Seems like they are intentionally congesting their links to force content providers to pay them extra for prioritisation. Ground rules for net neutrality are needed.. badly.
The article indicates a 1:5 upload:download ratio. Would this be because most plans have e.g. 1mbit up : 10mbit down throttling (or similar) ?
I find it interesting that they could increase their upload speeds with minimal performance hit, or would that take away their argument against level 3?
Seriously, this is like arguing that a road construction company doesn't have EXTRA/SPARE asphalt spreaders...
If an ISP is expected to have, say, 20% extra capacity, that ISP is wasting money on unneeded capacity, impacting their bottom-line.
I suspect this leaked doCument came from someone in that wants to sell Comcast more capacity...

When I lived in the Washington DC metro area it was common to see 10% - 15% packet loss at the comcast border/peering routers during peak usage hours (7pm - 10pm). It was pretty much useless for gaming or anything else remotely interactive. Calling to complain was an exercise in futility as you couldn't actually talk to anyone who remotely understood what you were talking about (and power-cycling my cable modem really wasn't going to solve the problem).
I don't understand this sentence : "Keeping their links full may ensure that content providers must pay to colocate within Comcast's network" I don't know how Comcast's service works
Interesting data, but I almost find more interesting the use of MRTG to show it. :) Perhaps we can infer from this that whoever grabbed this traffic wasn't using Comcast network tools, and instead used their own tools for a simple and easy setup? Hmm. :)
Is this unattended (torrent) activity? I find it hard to believe that it is active web surfing / video streaming for the majority, unless daytime usage is extremely low and what we are seeing is that the network is completely overwhelmed with modest/typical use by 2nd/3rd shift shift workers.
Did anybody notice that the two graphs are taken from different interfaces? Also, it looks like the traffic only recently got that high. Either way, It seems irresponsible to let the traffic get that high without upgrading.
The Comcast argument is that they have a peering agreement with L3 (and TATA too) but that is simply not the case. Both L3 and TATA are providers for Comcast.
TFP (The Fucking Post) points out that Comcast runs its terminations with TATA at full capacity for most of the day and concludes that they do so on purpose to force services like Netflix to co-locate with them (= $$$ for Comcast.)
So L3 says to Netflix.. "Hey.. you dont need to be a slave to the Comcast overlord" and Comcasts reponse is to re-brand its business relationship with L3 as a "Peering Agreement."
Many slashdotters bought this bullshit hook, line, and sinker on the last Comcast vs L3 article. They did so because they learned about peering relationships at some point in other slashdot stories and took their 1:1 free peering knowledge and incorrectly applied it to the L3 and Comcast relationship.
L3 is Comcast's internet provider. Comcast's claim is like you claiming that you can charge your ISP because more stuff comes downstream to your LAN than goes upstream from it.
"His name was James Damore."
No, it's more like the construction company is taking forever to finish the road, and by happy chance they also operate the toll booth on the only alternate road.

Can't this backfire on Comcast? I mean, if a Comcast customer tried watching Netflix and they can't get a good connection because of congested links, the user isn't going to think "Netflix is crappy" they're going to complain aboyt how they've got such a crap connection through Comcast.
That's only meaningful if there are alternatives/competition in the area, and there might be an argument that Comcast wants to push it's own video streaming service (which wouldn't crap out).
So - Internet access is Universal Healthcare now? Comcast is a business designed to make profit yes? Best way to make profit in the internet business is to maximize your resources. A 100 percent full pipe is an efficient use of their resource. Geeze, slashdot is so full of whiners and babies it sickens me. Nothing prevents you from shelling out the dough to buy a dedicated 1:1 ratio pipe from a Tier 1 or 2 provider. Oh, wait, it costs to much? Then stop your bellyachin'

I would agree, but if adding another link only gives them 5% unused, and they can deliver the speeds they advertise, wouldn't the cost be worth it to stop all the outcry?
GENERATION 25: The first time you see this, copy it into your sig on any forum and add 1 to the generation. Social exper
The road construction employees are demanding bribes from motorists to allow them access to finished lanes which were already paid for by taxes on the motorists. Those unwilling to pay the bribe are routed to lanes still under construction that are populated by workers who do nothing but hold flags and scratch their butts. In other words, Comcast is full of useless butt scratchers who are trying to scam you.
Actually, if one factors in previous /. posts about Comcast, a more appropriate example is more like a private toll road company getting right of way for an eight lane expressway. Instead, they build a two lane, then whine to Congress that they are being abused since their road has cars on it 24/7, and instead of widening the road, they start charging people money per minute they are stuck in bumper to bumper traffic on the road, doubling tolls, and demanding that shops located off the highway pay money, or else the exit to those places would be closed.
Unlike a spare part you don't pay for extra capacity. Transit billing is generally 95th percentile you throw out the top 5% of samples and bill on the remaining peek. From a design standpoint if you had two links you would not want to see either running over 50% from a billing standpoint you pay about the same for two links 50% used as you do one link at 100% so there is little reason to max out links unless there is a failure and it's picking up the slack.
No sir I dont like it.
A 100 percent full pipe is an efficient use of their resource.
It also limits the ability of Comcast's customers to use the 6 Mbps downstream burst capacity that Comcast has advertised to them. When an oversold link flat-tops, it's been over-oversold. If Comcast is not capable of bursting at 6 Mbps for the majority of the day, it shouldn't even be advertising 6 Mbps, let alone "PowerBoost".
Now, I'm not exactly glad I have the ISP that I do, but anything seems better than Comcast after everything I've heard about and from them over the years.
I won't do business with Charter because I don't like how they've done business in the past. I can't get a wireless provider because I live in a small dead spot. I'm stuck with AT&T DSL and I get terrible speeds because of a similar dead spot.
I live, it seems, in the middle of a circle. This circle is made up entirely of residential homes and apparently companies either don't want to, or are being denied the opportunity to install a cell tower, phone switch, or anything of the sort closer to my home.
Basically, this all means that the only ISP that can possibly get me decent speeds is a company I won't do business with on principle. I'm sure if it came down to it and Comcast was the only provider I had available to me I'd seriously consider satellite.
How do they make money? What they do, as a private company is not exist to make money, but exist to provide something to customers who have money.
Without customers, Comcast doesn't exist.
Funny how all pro-capitalists forget that.
Most ISP sell you a broadband connection and punish you if you use it to the full capacity. But somehow they should be allowed to use the full capacity of their connection to the outside world, and therefore offer a crappy service?
They're a customer of Level 3 & this guy gives his analysis of the issue (found in followups to the NANOG posting)

I don't understand why people are shocked at this. It's actually expected for a for-profit company to do shit like this. In capitalism, lower supply = higher prices = higher profit.
This is why Disney only releases their DVD's once every few years; they get to charge more because of it. This is why Enron shut down half of its power plants in the west; less power means there was a shortage and they could charge more for it.
And this is why Comcast artificially lowers the supply of bandwidth. They get to claim that people are using too much of it and therefore have to start charging more for it.
This is why a company should never be allowed to be in charge of an ISP. The profit motive is too large for them to not fuck with it to everyone's detriment.
No, it's more like the construction company is taking forever to finish the road, and by happy chance they also operate the toll booth on the only alternate road.
Sounds like Texas.
Gas/oil companies do the same thing. It's cheaper to run at 99% capacity and manage demand than it is to limitlessly create extra capacity.
And what would be the point of class action? Comcast will eventually settle for "undisclosed sum" with out "admitting wrong doing," Lawyers walk away with millions while the rest of Comcast customers gets a 5 dollar coupon off the next month.

I'm waiting for the day CSN is a web available service. That's the day I can finally cute the cord on my cable (which is not Comcast BTW). I don't actually mind paying Hulu $10 for their service, and then forking out another $10 to Comcast for CSN (if/when available) for internet delivery. My cable bill is almost $200 with internet service, so cutting that down to the $60 for internet plus some set of subscriptions (say another $50), and I'm still saving a ton of money. I think this is something that scares the bejeezus out of cable cos. The thought that they would be relegated to simply being an ISP probably makes them sleep less well every night.
Bah
A saturated link is not ideal. It is less efficient than a link without 100% utilization, because packets start dropping and getting re-sent, along with the associated ICMP traffic.
I completely agree. In fact, for the Federal government, building out infrastructure (roads in the days of the writing of the Constitution) is a mandate. A smart government will let the free market work when and where it can, because a truely competitive market is virtually impossible to beat on a cost/performance level by any government.
I was just reading a story about how the state in last place for broadband access (surprise...Mississippi) has used Federal dollars to build out a web site how what vendors provide broadband access to places where you live. Talk about a waste of money when there are dozens of sites (some by vendors others by aggregaters) that do the same thing long before the Mississippi site was introduced. The state should have used that money to actually build out some sort of broadband access for the areas that don't have it. For example, they could have literally funded the electric co-operatives to build out the data over power line systems. This would have created more competition because the co-ops operate in many of the places where the phone and cable companies do - thus adding more competition, while providing broadband to the unserved areas of the state.
Doesn't this effectively amount to fraud? Comcast knows there is no way it can deliver the bandwidth it's promised to its customers.
Welcome to the "free" market
Welcome to a Natural Monopoly due to Network Effects and a lack of regulation---quite different from a (well-functioning) Free Market.
I use Netflix and Comcast. We use a lot of Netflix and I've never had a problem with viewing movies anytime I want. We have 2 iPhones, 1 Mac, a Wii, and 1 AppleTV all enabled for Netflix with 2 users and we both watch sometimes. I measure from 5 Mbs (worse case) to 18 Mbs on DSL Reports at various times. I also have the option of moving to FIOS and I have not because I never have trouble with Comcast. Whatever the graphs show for a single congested connection does seem to be causing this user trouble. These graphs do not measure my ability to download. Excuse me, my 3GB XCode update just finished, back to work.
Comcast claims that a good network maintains a 1:1 with them, but that's simply not possible unless you had Comcast and another broadband access network talking to each other. In the attached graphs you can see the ratio is more along the lines of 5:1, which Comcast was complaining about with Level (3). The reality is that the ratio argument is bogus.
Comcast claims that free peering arrangements should have close to 1:1 ratio. And if you don't maintain that ratio, then you should pay for transit, just like Comcast is doing with TATA. So this is entirely consistent with what Comcast is saying and if anything supports their argument, not undercut it like Backdoor Santa is claiming. His argument about saturating transit to force other to peer with Comcast is valid though.
I personally think it is garbage to apply Tier-1 peering standards to (what should be) a CDN-ISP peering arrangement as they are completely different situations with different economics. It would save Comcast money and improve their customer experience if they were to enter into a free peering relationship with L3-the-CDN, because without the peering agreement Comcast-the-ISP would have to pay someone transit to access this data.
But to play devils advocate, here is the issue from another perspective. Comcast actually has a it's own Tier 1 network now, in addition to the last-mile network that we normally associate them with. This includes many business customers who are content providers not consumers. Comcast is using this CDN issue to force L3-the-Tier 1 to start treating them like a Tier 1. L3 wants a traditional CDN-ISP peering agreement where they to route their CDN data over their backbone network and connect with Comcast at the closest possible location to the customer, with only data intended for those customers. Comcast wants a Tier 1 peering agreement where their networks connect at a smaller number of points, and more data would be routed over their Tier 1 network, and then they balance the ratio by sending more traffic L3's way for free. Think about it; if Comcast was paying any other Tier 1 for transit, then L3-the-Tier 1 would have no issue peering with them. So if Comcast builds out their own Tier 1, why shouldn't L3 treat them the same?
L3 is trying to use it's backbone capability as an advantage to support it's CDN, and Comcast is trying to leverage it's position as a huge ISP to push it's Tier 1 network. In the end, because there is a lot of competition between CDNs and not so much between ISPs, Comcast has the upper hand.
Which is scenarios is more likely: Customers
1) Recognize that this is a problem with Comcast not Netflix
2) Have another option for broadband connectivity
3) And choose to switch solely over this issue.
or
1) The customers blame Netflix for the problem
2) Netflix realizes that L3-the-CDN isn't providing the level of service they wanted.
3) Netflix switches to any number of high quality CDNs that do have peering agreements with Comcast.
Comcast has the stronger negotiating position here, which is why L3 gave in.
I think it would be a delicious irony if as result of the scrutiny Comcast is receiving due to their proposed acquisition of NBC regulators not only to denied the acquisition but further split the company in half. One half would be Comcast cable and the other half would be Xfinity broadband. Comcast cable would be forced to lease the last mile lines to Xfinity as well as any other broadband provider that is interested. That would be justice and therefore it will never happen. We're just going to see a ban on charging for traffic that terminates in their network.
I disagree with your contention that you can build your own infrastructure. I live in a condo with some stringent rules about what can go outside. There is no question of the association allowing a satellite dish. Even if I could, the area I live in has a LOTS of trees, there is no way I could get a clean line of sight to a satellite.
Isn't it best to allow the citizens to pool their resources and built one. Oh yeah, we have something to allow citizens to pool their resources, it's called GOVERNMENT. If commercial interests won't expand their networks to allow for increased demand, maybe it's time for the government to offer some real competition to the Internet monopolies.
Comcast is also doing stupid things with their Internet routing. For example, to get from Denver to anywhere else in Denver, you go through Dallas. This adds at least 30 ms to each ping. This is actually one of the more efficient routes they have now; google on CRAN and traceroute and you'll see.
Their rationale is that CRAN is all 10Ge, and therefore no matter how far it travels it will always be faster than any other connection via their peers (even if those are all 10Ge). Apparently Comcast has FTL links.
Oh, here's a hilarious quote from a FAQ on the matter:
"Such a network can provide network speeds far in excess of what Verizon's Fios offers with little upgrade by Comcast should they want to offer equivalent speeds.
All areas are being converted to the CRAN. The most apparent thing you will notice when you are switched, is the additional hops. These hops have little to no effect on speeds or latency. The good news is; by keeping the traffic more internal, it reduces cost to Comcast and allows the subscriber to put a less detrimental affect on the network."
I love the bit about how they could easily offer faster than Fios speeds if they ever felt the need to compete, which they don't.
Well this fits quite well with Comcasts complaints of people hogging bandwidth.... all part of their plan. Coming next will be there application to apply Bandwidth Metering. Everyone knows the Cable and Telcos would love to be able to bill their customers with Metered internet usage..Cha-Ching!
No, my friend, most of them are not technical. After they decide the Internet is broken, they'll go to The Google and see that that page is OK, and decide Netflix sucks.
They know they have 6M per second and that that is a LOT -- way better than that DSL thing. They don't know about those places out there, and will blame them. One generally blames that about which one feels one knows less.
We know Comcast sucks because we're techies. They only know Comcast sucks because Comcast doesn't show up when they say they will for an install. Other than that, it's a black box for them.
Time Warner does the same thing - they advertise their speed and throughput, but when challenged with actual performance results (once you sign up and discover important things like latency and throughput are actually worse than some DSL providers like Cincinnati Bell), their sales engineers say their claims are for traffic within their own network only.
Since when does the Internet live solely within Time Warner or Comcast's own network? This is a completely misleading and unrealistic benchmark.
I called Time Warner out on this, said it was false advertising, and that their Business Class contract with me was not valid. They retrieved their equipment and complied with my rejection of the first month's use bill they sent me afterwards.
The solution to this entire thing is simple. The FCC simply needs to create rules that classify speed packages and what those speed packages mean. ISPs can only sell using these FCC defined terms. 3MB services = 3MB of data per second can be transfered at any time of the day, from the cusomers end point to the exit point of the ISPs core backbone.
It would be fairly easy for the major carriers to setup tests sites just like DSL reports. Could test their connections and report trouble right from the site. The end result would be the majority of US customers would find out they are getting less than 10% of what they pay for.
If this gets bad enough, competition shows up. The informed people go for the better service, and others follow. Then, nobody bothers paying comcast for co-location anymore. Their remaining customers get packet drops...
Truly amazing. After having just pointed out that they dont operate in a free market and how that causes the problem, you then do a 180 in your concluding paragraph and say:
Your cognitive-dissonance circuits must be working lots of overtime.

Not defending comcast necessarily here, but I am a network engineer (not for comcast)
Look at the month-graph. The flat-top congestion has only just started in the last few WEEKS, and it appears traffic has picked up sharply starting around Nov 21.
There are many reasons why you could see an uptick in traffic. Some:
* December is just a high-traffic month.
* a link failed elsewhere in the network
* TATA inked a deal with some other company to start carrying their traffic (same as Level3's CDN deal) and now pushes more via this link
note the green line is about the same as it was when the link was not congested. Are people downloading more? Why did inbound increase while outbound decreased?
The internet is asynchronous. comcast may have a 1:4 traffic ratio with TATA, but they may have a 4:1 ratio somewhere else. That big of a disparity is not super likely, but it's very complex to control which links your inbound traffic comes in on, since that is determined by the routing policies of other ISPs and their customers. I see this sort of imbalance our own (many 10g internet) links frequently. They likely have several tens of 10g links for internet service, this is just one. Be careful extrapolating too far.
How long do you think it takes to add more links/capacity? Would you buy more for 1 month of relief?
As someone who also works for a cable company, no not comcast, that graph alone makes no sense. The peak times are all during off-peak hours, I would expect if this was really a graph of Comcasts pipe that, at the very least the bandwidth usage would be peaked at 7-9 pm.
Not defending Comcast, but basing your opinions of this badwidth usage graph seems iffy at best. Also, I sincerely doubt that Comcast has a single pipe to the internet, they likely have several all muxed together, using something like BGP.
You got what you paid for. It's in the legaleeze of the fine print. Did you read the fine print?
Now I'm not supporting comcrap. I have them and have no choice but to cry that you had no idea what you paid for when it's all there for you to read is dumb.
If it were false advertising they would be sued...and have been. If you think you've been the object of a crime you should sign on to a class action lawsuit or sue them yourself.
Whoah dude....how do you THINK they GOT their MONOPOLY.
Government Regulation
But that doesn't help if the Internet user lives with relatives who 1. are happy with the Comcast TV service that they have had for over 30 years, 2. are still paying a monthly rental for a cable box that they no longer use and lost over 15 years ago and don't have the disposable cash to reimburse Comcast for lost equipment, 3. don't want to go into a 12- or 24-month commitment, 3. have heard unsubstantiated horror stories from friends and families about FiOS, and 4. don't want to have one company controlling TV, Internet, and home phone.
If you look at the 30day graph, the situation loses a lot of the spin being placed on it: up until 2 weeks ago, they were doing fine, only peaking briefly at 10G with no upward trend. Then two weeks ago, a significant upsurge (online christmas shopping would be the obvious answer, but surprised it's costing *that* much bandwidth). You don't put in 10G lines overnight, and not if they're only going to be used for a few weeks... They clearly needed to be planning for it, but it wouldn't surprise me if it were in next year's plans...
Does this really need to appear on slashdot? As if the nanog mailing list hasn't been infested with opinion and nonsense enough already these stunts are only making it worse. Just stop it!
I've been a Comcast Internet customer for many, many years and would LOVE to be a party to the coming Class Action. Sign me up!
Seriously! I must be the luckiest guy on the internet because I don't have anything to complain about with Comcast. I've moved around a decent amount in the past few years in central NJ near the shore and have had the following experiences:
Comcast in Monmouth Beach and Long Branch:
I think this was back when the max was 6 or 8Mbps. Didn't block ports. Had a few issues with the lines running to my older apartment but once those were settled it was smooth sailing. Never really noticed "slowdowns" that the DSL people raised their noses about their non-shared connections.
Cablevision in Neptune and Asbury Park:
15/2 was the stock connection here I believe. Started using newsgoups and had no trouble maxing out the downstream at any time of the day.
Verizon FIOS in Asbury Park and Ocean, NJ:
Switched to FIOS solely for price reasons on a package deal. Base internet was supposed to be 15/5 but somehow I ended up getting a 25/25 connection. Not complaining. As with the previous Cablevision connection, had no problems saturating my downstream link downloading from the right servers.
Now I've moved to Aberdeen, MD and am back with Comcast due to the owners of my rental not wanting me to have FIOS installed. I ended up getting an internet-only package and now have a 50/10 connection for $50 a month. Yes...50Mbps. The kicker is, when I go to speedtest.net I get rated at 62/11.5. So now I'm downloading from newsgroups (using ssl at that) at just shy of 7MB/sec. I've never had issues with it going slower.
TL;DR:
I have a 50/10 Comcast connection that never slows down and speedtest.net says is actually 62/11 for $50 monthly, Netflix streams great.
Youtube, as usual sucks. If Comcast (and Verizon FIOS for that matter) are throttling anything, it's Youtube. That's the only thing I could even remotely say is slow.
Being an experienced network engineer, I can tell you that this graph is expected. TCP, by nature, uses all of the bandwidth it can due to its windowing mechanism. Since the FCC doesn't like carriers limiting people's use of applications like Bit Torrent, Youtube streaming, or the like, the pipe is naturally going to be full. There is nothing Comcast could do about it. Is it overloaded? Probably not. To show a "good" looking graph, you would have to have a pipe so large as to allow every communication to finish instantaneously, or very very quickly, thus not allowing TCP to expand to the full pipe in the time allotted. As you can see, the stream going out of Comcast is small-medium, because very few people probably host websites on the Comcast network. The transmissions are also reasonably small for requesting websites, and so, the transmissions complete quickly, thus allowing the graph to represent lower utilization. So, in the end, this is why Comcast is pro Internet prioritization, or QoS, really. To make something very clear, I am not affiliated with Comcast, so don't ask.
if you were me, you'd think the same way
Ba Dump!
For a lot of people the sporting events are the key. If I could stream sporting event (even if I paid for them individually in a pay per view model) for Blackhawks games and Bear games I would drop my sat provider in a Chicago minute (which is slightly less hectic and less rude than a New York minute)
think it would be a delicious irony if as result of the scrutiny Comcast is receiving due to their proposed acquisition of NBC regulators not only to denied the acquisition but further split the company in half. One half would be Comcast cable and the other half would be Xfinity broadband. Comcast cable would be forced to lease the last mile lines to Xfinity as well as any other broadband provider that is interested. That would be justice and therefore it will never happen. We're just going to see a ban on charging for traffic that terminates in their network. The rest of the car is left pretty much unchanged at first glance, but the beauty is in the details - slightly redesigned tail lamp cluster, body-coloured rubbing strips on the sides and an all new rear bumper with sharp reflectors on the far corners. The new i10 also gets turn indicators on the wing mirrors as standard fitment - a first in its class. mirc porno izle mirc yükle sikis izle turk porno
That isn't an issue if you don't oversell. If you sell x customers y available bandwidth you need to have x*y bandwidth available through peers.
A lot of people keep repeating this, but it's bullshit. No efficient network operates like that. The whole point of a network is to share the costs of a fast network, so that everybody can get a higher speed than the could otherwise. The only way to guarantee the performance you're demanding here is to use dedicated point-to-point links.
This comment by Late Adopter above lays it out fairly clearly. The total bandwidth demand by x users with connections of speed y is much lower than x*y. The shared network needs to provide that much upstream bandwidth. Comcast are in the wrong because they are evidently providing much less than the aggregate demand. Your "don't oversell" rule is wrong for the opposite reason, which is that it would provide way, way too much.
Are you adequate?
...Comcast, AT&T and others are really just common carriers. That's why I say that Net Neutrality is a ruse.
The diversity and expression of human opinion is essential to human survival.
I wish people would stop suggesting this. It is a terrible idea. Last mile is NOT a natural monopoly. Cable is cheap. We do NOT want the government trying to run any part of the network. Governments do some things good. It is the things they are good at that you want them doing. Most governments are good at building networks of pipes through cities. I don't mean pipes euphemistically. I mean real concrete/steel/plastic/etc. pipes. Tubes. I have 3 sets of pipes running into my house now, and a 4th that reaches the street at the corner of my block. PG&E runs gas pipes into my house, and the city runs water and sewer lines to my house. The city also runs storm drains to the corner of my block. Physical pipes are a solved engeneering problem.
Lets get municipalities to start putting one more set of pipes into our homes. Make them the size of the sewer system. With actual pipes running to the homes, the municipalities can rent out space to run cabling to anyone that wants to pay the fee. This way the cities stay out of the ISP business, they collect money for pipe usage, citizens get competition, and upgrading the infrastructure becomes dramatically less expensive as new technology comes out.
A pipe system the size of our sewer lines would would easily handle Petabytes/sec of data. At that point, wire is not the bottleneck. Switches are.
Cite me one example of a "well functioning" free market that has existed without externalities, regulation, protectionism, network effects, AND which operates with consumers with perfect knowledge making rational choices.
I'll show you one when you can show me a spherical vacuum of uniform density ;-)
That's to say, Free Markets are a model of reality. Like any other model, one of my (Comp.Sci.) professors' quotes applies: "Of course it's wrong---it's a model".
Being wrong due to it being an oversimplification, I can't show you perfect information or perfect rationality or perfect deregulation or [...].
But I can point you to empirical evidence that economics has gotten a thing right or two; I'm not going to look it up now, but somewhere in the first nine chapters of Hal Varian's Intermediate Microeconomics, he references an observation study which suggests that 93% of consumer decisions with respect to transportation choices can be explained from an interpolated linear utility function, in accordance with fairly standard Consumer Theory.
For more: see maybe EconTalk's archives and EconLib; they have a strong austrian bent, at least Russ Roberts does, FWIW. Or the intertubes.
Based on my somewhat shallow understanding of the US ISP market, it seems that "Competitive Market" is a less accurate model than "Oligopoly" or "Cartel". The latter are still wrong because they're models, but they're less wrong because they're better models (again: in my head).
Further, we can explain why there's an Oligopoly by Network Effects (although I think Large Fixed Costs To Entry hold quite a bit of explanatory power too, to the extent they're different).
Also, if Free Markets are not the best models of the following sectors, please let me know what you think the most accurate model is and why:
Bicycles, bicycle repair services, food (e.g. at the grocer's), restaurant meals, gold/silver/(each other metal), wood, glasses and optician services, soda, glassware/ceramics and kitchen utensil, household machinery (washing machines, spin dryers, dishwasher, vacuum cleaners, ...), furniture, storage space.
A completely orthogonal question is this: "are de/unregulated markets the best way for society to run?" I think the answer varies depending on sector. Some sectors are natural monopolies, or have built-in externalities, or are non-rival/non-exclusive goods, or have other market failures. It makes sense to do something other than "Free Markets" in those situations. In other situations, letting free markets do their thing is best.
Finally, I'm surprised by your strong reaction. It looks (and I'm guilty of exaggerating here) to me like you think I just killed your puppy. I'm curious; Why is that?

I read the article and looked at the graphs. I understand what the text says, and it makes references to the graphs. The problem is, the graphs are meaningless to me and they aren't explained anywhere. What am I looking at?
I would be more inclined to accept the article if Backdoor Santa would care to explain the graphs. What axis (left or right) is used for what curve? What does each curve measure? Please be specific enough that I could (mostly) replicate the graphs if I took my own measurements (measuring what?).
