Cable Co's Want More Control Over Your Network
Moonshine Coward writes: "'The CAT and the NAT' in latest issue of www.cedmagazine.com discusses Cable labs and their efforts to come up with a 'better' protocol than NAT that allows them more control over devices behind your cable modem. Their upside on this...$4.95 per IP per mth.
Their #1 concern...people putting in 802.11b hubs and sharing with their neighbors.
Fine in principle and if it gets them drooling enough to speed up the deployment of fiber to the home it might be a good thing. However I can see way too many downsides...not least of which is being nickled and dimed to death..my webcam, cable ready microwave, refrigerator, pictureframe that shows revolving jif's ... each costing me $4.95 p.m. -- all on top of regular $39.95 cost." Note: the article is written from an interesting point of view -- it's aimed at the people who want to collect the additional per-IP charges.
What relevance does the number of devices behind the cable modem have? The reality is that the real load on their system is gross throughput, and if there really is a problem of abusers then the natural solution will be in the realm of additional bandwidth costs: Joe will be a lot less likely to set up a 802.11 network if it costs him $5 / GB past 5GB or whatever.
As a bit of perspective here: I hope they didn't have to do any of this, but the reality is that the "honest" among us end up paying when people abuse these sort of commercial services : i.e. they price based upon the requirements to support the average Joe's bandwidth, so when BillyBob opens up his cable modem to 10Mbps with SNMP and then sets up a warez FTP site and shares his connection with his apartment complex, then that ends up cost ME more in the long run (or alternately, and worse, the service is withdrawn entirely because it isn't economically viable).
(Well, okay, the real argument is probably that the providers see a way to make more money but....)
I pay for a certain amount of bandwidth. Why do they care how it gets used? If I spend my 10 MB/s downloading porn or if I only use half of it and then let my neighbor use the other half...seems like the problem is not people "stealing" bandwidth but the providers not provisioning correctly.
This article is a misleading justification of price gouging. "The good news is, the dishonest people who know how to do it are already doing it..."; clearly anyone with two computers must be a dishonest thief.
They discuss sharing amongst neighbors, but what they are really upset about is not being able to charge for every device I own or sharing amongst roommates. Nowhere is the fact that even toasters are getting IP addresses mentioned, and none of the technology they are looking forward to will allow the provider to differentiate between my toaster and my neighbor's computer.
So the interesting question to me is, why does my service provider deserve more $$$s because I own three computers, a net-connected TiVo, and an internet enabled toaster or stoplight? Aren't they still just providing me a single connection and some bandwidth? What right do they have to charge for my toaster? Do they have a contract with *me*, or with *my device*? They seem to think they are providing my computer with a service; I happen to believe my computer can't sign a contract, so the service is provided to me, and this price gouging shouldn't be allowed.
is competition good, or is duplication of effort bad?
How long is it going to take before ISPs start realizing that Internet Service Provider means Internet Service Provider? I just want a pipe with some bandwidth, to use as I want. This seems a simple enough notion, but the ISPs are all into "we'll sell you a piece of a pipe, as long as you don't use it much, and not for things we don't like."
Clue to ISPs: Sell the pipe. Don't worry about what goes through it unless you're sitting on a subpoena or something. Everything else is silly optional garbage.

I used to work for a cable modem ISP (until they went out of business last January). People sucking up an inordinate amount of bandwidth on "consumer" accounts were a huge drain on our resources. Usually it was spammers or people running high volume websites at home, but we also had a few folks with as many as 30 computers on one cable modem. We were only charging them $50 a month, but they were eating up almost an entire T1 all by themselves. Losing $1000 a month to one customer is not a good way to stay in business.
It got so bad in one area we actually started putting together a database of MAC addresses, trying to map them to individual customers (even with NAT, the MAC address of the original computer is in the packet). Unfortunately, that project was just starting when the company filed for bankruptcy.
That said, an easier and more effective solution would be to put QOS restraints on people. Who cares how many devices are hanging off one network connection? It's the bandwidth they're using that's important. And if bandwidth were limited to cable modem customers they wouldn't be so eager to share what they have with all their neighbors.

That's right a "Technology Analyst" with an AOL address. Fuck, I wonder how much this person gets paid, an easy job, easy money, and you don't have to know shit about what you're talking about.
Someone needs to smack this person with a cluestick. Has this person heard of cable companies that encourage you to use NAT? What does this person think that a gateway running NAT would look like to this fancy new computer counting technology? Has this person actually neworked two computers together, or did (s)he just read "Wired's history of the Internet and NAT, for dummies?"
The problem is that the cost structure of ISP services doesn't match the pricing structure. Charging per bit moved wouldn't work, because for most residential service the main cost is infrastructure support (the cost of maintaining the pipe, regardless of whether it's used). But charging only for access, as is currently done, doesn't reflect the scarcity of the actual resource -- bits moved.
The only reason we (residential customers) have to sign no-resale agreements is that the ISP's pricing structure is a poor match to the cost structure. Think about it: if the match were better in the high-demand case, then no agreement would be necessary. Does the power company forbid you from reselling your power? No -- but it doesn't make economic sense for you, because the price structure matches the cost OK in the high demand case.
The no-redistribution agreeent is a kludge that doesn't even work to limit customer bandwidth in all cases. Typical ISPs might oversell their pipes by a factor of 50, so each user must stay below 1/50 of their long-term-average bandwidth or else the ISP loses money. I just upgraded my DSL connection to 640kb symmetric, and one use I'm putting the pigger pipe to is listening (at work) to my home mp3 jukebox. That uses 128kbps, or just over 1/5 of my pipe -- so my ISP, who charges only for access, loses out on the deal if I leave the stereo running all day.
A low-volume NATted subnet doesn't affect the fan-out rate nearly as much as a heavy data mover like my mp3 stream -- though it does use slightly more bandwidth. A high-volume NATted subnet increases the spikiness of the load on the ISPs pipe and requires beefier infrastructure -- so you should pay for it.
It seems to me that the ISPs that charge nothing up to some volume of data flow, then a fee per gigabyte above that, have the right idea. That charging scheme matches well with the actual cost of high-volume users. (Cell-phones work that way too...)
Except there aren't any additional IP addresses being used. And of course, as with most speculative damages, this fails to take into consideration the fact that many of these additional computers would not be networked for internet access at $5 per month if there were no "free" alternative available. Consumers gaining functionality does not automatically equate to companies losing profits, especially if the service offered is not the one desired (IP addresses vs. just a data pipe).
With NAT-based hubs, cable providers won't be able to see into all connected devices-making remote troubleshooting difficult-because, again, the NAT is speaking for all connected devices.
Oh no, my cable company won't be able to mess around with the equipment without my knowledge. I'm so worried.
CAT could replace NAT altogether, at least in equipment hand-picked by MSOs for home-network service packages. ... At the very least, cable MSOs involved in CableHome want a counting mechanism, with parameters set by them, that specifies a maximum number of connected devices.
Um, why should my cable company be able to penalize me for having devices that aren't routinely (or ever) used for internet access? So I guess I'll need NAT in the CAT... This whole article is one big piece of misinformation and FUD. My cable company doesn't need to know what I have on my private network - they provide the pipe, I use it. They might be able to monitor some of the data that goes through their network, but anything more invades my privacy (ethical argument, not legal argument) and puts my network at risk of attack. NAT will be around until the cable companies buy a law banning it, and then it will still be around illegally.
I'm sure many of you have seen those hilarious DSL commercials that cast cable-based broadband access in a bad "shared access" light. That's because the current Data Over Cable System Interface Specification (DOCSIS), 1.0, is a best-effort packet delivery system and thus has no guarantees for Quality-of-Service(QoS). Thus, the cable operator (MSO) has no way of throttling bandwidth, especially upstream bandwidth. That's why the MSOs don't like NAT and want to be able to bill their subscribers on a per IP basis. Enter DOCSIS 1.1, essentially a QoS add-on to DOCSIS 1.0 . With a DOCSIS 1.1 Cable Modem Termination System (CMTS) sitting at the MSO's cable head-end and a DOCSIS 1.1 cable modem (CM) sitting at your house, QoS can be guaranteed. That is, the MSO can both limit you to a certain upstream and downstream bandwidth as well as guarantee a minimum upstream and downstream bandwidth. So, given a DOCSIS 1.1 deployment, I see no need for the MSOs to agitate customers with this intrusive CAT proposal, since they now have a way to bill you by bandwidth. Two months ago, the first set of DOCSIS 1.1 products were certified by CableLabs. However, I don't expect DOCSIS 1.1 deployment and replacement of DOCSIS 1.0 systems to happen in large numbers until the end of 2002. Another insider note: CableLabs, the entity pushing CAT, is funded by the MSOs, but has no authority to push its proposals into implementation. Only vendors building CAT products and MSOs buying those CAT products have the power to deploy this ludicrous CAT proposal.

Uhm, Cable droids, that's what my firewall IS THERE FOR!!! Damn skippy you ain't gonna see what's behind my NAT device, you and every NetBus packing, snot-nosed, loser script kiddie out there. My provider has this little numeric string that can be used to gain access to my machines if need be: My phone number.
Insanity is the last line of defence for the master diplomat. But you have to lay the groundwork early.
Your CAT NAT replacement technology is based on the faulty assumption that you're selling a 'subscription' to the Internet. That is an extremely cable providerish way of looking at things, and precisely the reason I avoid cable (and tell my friends to as well) like the plague.
What you're selling me is a connection to the Internet. You're selling me bandwidth. That's all you're selling me. That's it. You can't care what I have on the other end of the pipe anymore than the water company can care whether or not I have a dishwasher plugged in or water a neighbors lawn.
If you're basing your pricing and bandwidth provisioning on expected usage, it's cheaper and easier to implement traffic shaping and aggregate (as opposed to burst) bandwidth limiting than it is to develop a whole set of proprietary protocols that people will just get around anyway, thereby starting a technology war (which cable companies will ultimately lose) with your customers. Then you can charge people if they want to exceed your expectations. This model is enforceable, will be seen as reasonable, and doesn't require expensive proprietary and invasive technologies to implement.
I find it kind of amusing (and scary) how so many companies want to have broken business models, call customers criminals when they don't work, and try to implement invasive technological solutions that give the service provider immense control. It's stupid and wrong, and you should know better than to have written an article advoacting such iodiocy.
Cable will never enter my home until you guys get a clue and stop trying to make me into a passive consumer instead of a happy customer.

The whole Cable Openness debate a couple of years ago was bogus, and ISPs and Cable Companies both mishandled it. Until PPPoE, the technically right architecture for a cable modem service was to do routing from the head end on up, which makes the traditional ISP's bundled service (modem access, routing packets to Rest Of Internet, and mail/web support) much less competitive, because it's Already Too Open - the cableco will route your packets anywhere you want them to go, without the ISP's bottleneck, and that leaves them competing with free email and web services (including the cableco's portals), so their only value adds are personalized service quality and avoiding advertising banners. The other two openness issues are wholesale pricing / billing, and the afore-mentioned service restrictions. PPPoE strikes me as an ugly kluge that's mainly designed to make it easier to shut off accounts for non-payment, charge extra for some services, and force traffic into bottlenecks like some ISPs, and it's a bad idea as are most of the different NAT options cablecos play with.
What the cablecos should have done is realize that they desperately need customers and use two ways to get them:
I've found the whole "Stop the Nasty Thieving Bandwidth-Sharers" publicity campaign to be in bad taste and a tremendous display of lack of imagination - not only do the cablecos have to cope with the reality of cheap radio and NAT hardware and NAT and routing software, but they Still desperately need ways to bring in many more customers, and should figure out how to use this technical opportunity to get them. Of course, cluelessness isn't a new problem for these folks :-) See: Use a Cable Modem, Go To Jail and the Slashdot Ensuing Discussion.
Lots of Disclaimers - I'm posting this as Anonymous Coward, because I do work in this industry and my opinions are Extremely Not My Employer's, especially the bit about Napster which I just didn't say at all, and you didn't read it here. But hey, I've been ranting like this for a while, and I'm not mentioning their names, because it's strictly my own opinions, not theirs, and besides, as a stockholder of several of these companies I'd appreciate it if everybody in the computer and communications industries could start to get some clues again. We need to start doing synergy, not fighting each other, so we can make some money. And there are several other rants I left out of this one, like how they've dropped the ball on totally transforming the voice telephony industry :-)
