negRo_slim writes with some welcome news from Ars Technica: "Comcast has 30 days to disclose the details of its 'unreasonable network management practices' to the Federal Communications Commission, the agency warned Wednesday morning as it released its full, 67-page Order. As FCC Chair Kevin Martin said it would, the Commission's Order rejects the ISP giant's insistence that its handling of peer-to-peer applications was necessary. 'We conclude that the company's discriminatory and arbitrary practice unduly squelches the dynamic benefits of an open and accessible Internet,' the agency declares." And from reader JagsLive comes news that Comcast has a different plan in place to deal with heavy bandwidth users: slow traffic for up to 20 minutes at a time to users who are grabbing the most bits.

Unix scheduling model for bandwidth? (Score:5, Insightful)
Comcast's problem has got me thinking, has anyone implemented a QOS mechanism that works like *nix CPU time allocation? In simple terms that's where a task's priority is determined as an inverse function of the amount of CPU time it wants. It seems to me the same thing should work just fine for bandwidth allocation. You just let interactive connections have as much as they want, and the continuous hogs get whatever is left - but you do this in a protocol-agnostic way that is based solely on demand.
But: this only would be appropriate if your goal is to deliver maximal performance under full link utilization. I don't know if this is a real problem for the cable providers - I doubt if last-mile congestion is as big an issue as people think. Probably they are more concerned about reducing their total cost for bandwidth to the internet. In that case the strategy of temporarily throttling the hogs seems reasonable and fair because it is protocol-agnostic, but ONLY if the specifics of this mechanism are disclosed to the customer, and this service is NOT advertised as "unlimited".

This type of throttling seems like it could be a real problem for Video On Demand applications, since suddenly slowing down your connection when you're streaming video could result in some pretty lousy viewing experiences.
Since Comcast itself seems like one of the companies poised to go into Video On Demand in a big way, this strategy seems like shooting themselves in the foot. Sure, they could have it throttle only if it's not Comcast's VOD, but then they run into the same issue with the FCC that they currently have with the P2P throttling.
I don't see how Comcast can do real content-agnostic throttling without screwing with its own content offerings. I guess that's the problem with being a bandwidth provider and a content provider at the same time.

If they throttle only users that aren't using Comcast VOD, it's going to be much harder to prove, since there aren't any fake packets being inserted in the stream. Also, since net neutrality is not the law, that sort of throttling might even be legal.

Hahahaha, that was priceless. You really think they'd throttle their own content? No, they're throttling Netflix and anyone else trying to do VOD.
Comcast offers VOD on their internal network, this costs them nothing. Netflix VOD comes over the Internet link they rent from another company, so they would rather make this unwatchable and continue to have a monopoly on content delivery.
They're preemptively trying to stamp out any competition but under the guise of "oh noes we're out of the bandwidths." Comcast charges plenty for the bandwidth you're using, but to push profits higher they need your Internet use to go down but your costs to go up. Just another instance where Wall St.'s "make more every year" mentality is going to hurt us more every year.

So set the limit at 6 Mbps. What, you mean Comcast can't deliver a continuous 5Mbps to all their customers? Are you telling me they oversold their bandwidth? Say it ain't so. :-D
But seriously, the right solution is to make VOD use multicast and treat multicast rates as the number of bytes streamed divided by the number of clients. Use the local hard drive as a very large cache, and by the end of the movie, you have the whole thing on your HD and aren't consuming any bandwidth. The notion of "live" streaming of movies off a hard drive in some server farm in a unicast client-server style is so 1985 (prior to RFC-966). After all, this is precisely what multicast was designed to do. If it doesn't get the job done, create a new RFC and a new underlying packet routing protocol that does, but could the cable companies PLEASE quit jerking everybody's chain and saying "Oh noes, VOD can haz mor bandwidth?" It got tiresome ten years ago. Now, it no longer qualifies as comedy and falls squarely into the bucket marked "that's just sad".

Yes, this has been integrated into Cisco routers for quite some time. It's called Weighted Fair Queueing [wikipedia.org]. WFQ schedules high-bandwidth streams in a round-robin fashion, yielding bandwidth to low-bandwidth streams so applications that speak infrequently don't get starved out. i.e. The more you talk on the pipe, the lower your overall priority becomes.

A significant point that often gets overlooked in this issue is that Cable companies and phone companies are generally government granted, government enforced monopolies. For example I personally am under the Cablevision monopoly. I couldn't have Comcast as my ISP even if (for some twisted reason) I did want to do business with them.
State, county, and/or local governments handle the access rights - running the Cable and Phone lines on public telephone poles or underground on public land. A company cannot simply come in and compete against the local Cable or Telephone monopoly. Most people face at best a duopoly, the very limited competition between Cable broadband monopoly vs the Telephone broadband monopoly.
So long as the government is involved in supporting and enforcing these monopoly market conditions it is entirely appropriate for the government to be deeply involved in the market conditions and business behavior. If a company wants monopoly usage of the public infrastructure like this it is entirely appropriate for the government to impose conditions on that usage.
It is appropriate for the government to manage the usage of public infrastructure for the public benefit. When the government meddles in a market to enable or impose a monopoly in that market, it is appropriate and necessary for the government to artificially impose conditions to replace the natural competitive forces that ensure a healthy beneficial marketplace. To replace the natural competitive market forces that are excluded by the artificial government sponsored monopoly.
For example if someone wants to go into business as an ISP that filters out porn and other arbitrary "objectionable" content, then sure, they are welcome to do so. *I* wouldn't want to use that ISP, but some people would want to do so. And that competing alternative is fine, so long as the government isn't handing them a monopoly on the market. If they were one of the Cable companies, and the government was handing them an effective monopoly position on broadband for a region, or even a duopoly position vs the phone company, then that would be a huge problem.

Right. If you build your private commercial network then I agree with you.

If you expect to do it based on privileged monopoly access building it on top of public telephone poles and public underground lines and other public infrastructure and other governmental benefits and governmental assistance....
well... if that were the case... well then you would be wrong.
If customers don't like it, they need to make it known via their wallets.
No. The government prohibits that. The government granted Cablevision monopoly market rights over my region. In other regions the government has granted Comcast monopoly market rights. I cannot do business with Comcast even if I wanted to. People in other regions cannot do business with Cablevision if that were their preference. The government grants and enforces these regional monopolies.
It is impossible to suggest the government should not meddle when the government is already involved. It is absurd to suggest "natural free market competition" is the solution to market problems when the force of government is prohibiting market competition.
