Re: Wrong!

I'll bet if you said on the phone: "I love you" to your girlfriend or wife and Nynex forged the packets soin your voice it came out: "FU*K you, bitch!", you'd be screaming bloody murder! But why can't they do that? After all, it's their network! R I G H T??? You are FUNNY, You Have me Rolling on the Floor, How did you get to this analogy???? |

Managing a network is one thing. Falsifying network data/packets to defraud your customers is another. Correct. And this article should not be titled "shaping" for the same reason. It's easy to assign BT packets a low priority relative to others and I support that practice. Complete neutrality has never existed and is a pipe dream.
Note that Topolski analyzes Comcast as falsifying peer responses only at the boundary and not within their own network. That's both a cost-cutting move and a marketing manipulation which he rightly emphasizes. Sandvine is lying in the name of users both in connection requests/acceptance and in BT-specific communications by changing message packets which say "I need this chunk to complete this file piece" to "I've completed this file piece." It's fundamentally different to lie in someone else's name than to prioritize packets network-wide.
It surprises that Comcast is relying on packet headers to ID the BT protocol when protocol (header) encryption has been a push-button feature in all dominant clients for over a year. It's a piece of cake to ID by user connection patterns ... just not at the boundary. Unlike Topolski's expressed opinion I consider the boundary-only practice a poor one even if it was done above board. It's a walled garden approach, albeit a half-step at the moment, and antithetic to global openness of the internet. Content originates from all over the world and Comcast's practice, if adopted by others, means content would have to be imported to each network by some other transport like FTP then re-published via p2p. Stupid and utterly anti-customer, anti-user.
Limiting both throughputs by protocol and connections per second at the account level during periods of high network load is perfectly reasonable. It solves all the loading issues of P2P and it's verifiably above board. I am continually mystified by the stance & behavior of ISPs on their responses to p2p. Neither the business practices nor technical aspects are obscure or complicated. P2P users would be happy to have their traffic slow down during peak times if they were confident traffic was elsewise unmolested. It's not like p2p content is time-critical like VoIP. |

If YOU OR I did this, we'd be committing a federal felony. Doing a computer crime like this gets investigated by Homeland Security.
But I guess when Comcast does it, it's AOK-especially by many of you.... |

Comcast is merely protecting their network from a peer to peer protocol that is extremely network management unfriendly. Well said. Cox dumps Bittorent freaks too called "powerusers" from my understanding. And, I hope they do, sick of powerusers running 24/7 downloading and providing since it affects other users experience. When @Home was around on Comcast, they had to throttle upload for everyone because idiots were running servers.
I don't think the TOS of any ISP allows illegal downloading. Now, if they were blocking Vonage, Comcast would be wrong. Bittorent, 99% illegal, good riddance!
Business class is what they should be offered.

Hmmm....does The AP's analogy make more sense to you?
From the Associated Press:
"Each PC gets a message invisible to the user that looks like it comes from the other computer, telling it to stop communicating. But neither message originated from the other computer — it comes from Comcast. If it were a telephone conversation, it would be like the operator breaking into the conversation, telling each talker in the voice of the other: "Sorry, I have to hang up. Good bye."
Who's laughing AT YOU now, dude? |

Re: Net Neutrality is NOT about being protocol neutral
What?! I'm paying $60/mo for service*--both upstream and downstream, and I actually want to use it?! Shame on me. (*but I'll be dropping Comcast presently)
"99% illegal"... you so funny.  Make up some more statistics, why don'tcha. You clearly don't use Linux. (Actually, the courts have been striking down TOS clauses as illegal over the past year or so. You can expect to see more of this.) |

Complete neutrality has never existed and is a pipe dream. It's really easy to talk about this and discuss the theory of it, but the actual implementation of such a system is plagued with complexity and technology limitations. Anyone who has ever implemented large scale IDS/IPS deployments knows all about the scaling factors that make this challenging. For this to work as you suggest the inspection probes would need to be placed in-line at all of the points that are being monitored today so that the packets could be touched/marked. Then you have the problem of how you place the traffic into a different class of service. Traffic shaping means queuing, and that's going to require memory on your routing hardware. Assuming right now Comcast is able to get everything done with a single queue per end-station attachment, what you propose would double the number of queues each CMTS needs to manage (one regular and one P2P queue for each end station), which could potentially drive expensive CMTS upgrades or even CMTS splits where adding more capacity to the existing hardware isn't possible.

That's both a cost-cutting move and a marketing manipulation which he rightly emphasizes. Sandvine is lying in the name of users both in connection requests/acceptance and in BT-specific communications by changing message packets which say "I need this chunk to complete this file piece" to "I've completed this file piece." It's fundamentally different to lie in someone else's name than to prioritize packets network-wide. That's reading *way* too much into what is taking place. Sandvine isn't interacting with the BT protocol, or touching the payload of packets at all. It's sending a packet with the RST bit set to 1 in the TCP header. To a certain degree it is a cost cutting move, but really it's a matter of balancing access to somewhat limited resources at the edge of the network.
I find it interesting that people are treating network communications between machines as the equivalent of constitutionally protected human free speech. The only way that legal argument is even plausible is if you personify the packets in an effort to describe what is taking place. If you're going to go on a moral tirade about injected RST packets to close connections in the name of bandwidth mitigation, then you better have the same fervor in arguing against satellite providers who are performing ACK spoofing to allow TCP connections to overcome latency limitations and allow for higher transfer rates. If something is legally wrong, it's not just wrong in the cases where you don't benefit from it. Manipulation of protocols is a common practice; technologies like random early detection intentionally discard certain TCP packets to trigger TCP to make flow adjustments, Intrusion prevention systems will inject TCP resets for connections where malicious signatures are detected, and routers will spoof the ARP response of devices off-segment to allow machines with improperly set subnet masks to still function.

Stupid and utterly anti-customer, anti-user. I'm not sure what you are defining as "the boundary"; this implmentation is most likely taking place at the distribution / aggregation layer between the individual CMTS hardware and the upstream Internet access routers. According to posts in the forum this connection limiting is taking place even between connections that only take place on Comcast's network. This make sense because the key point of contention is not the Internet access circuits; Internet bandwidth is dirt cheap and easy to come by, especially when you have your own nationwide fiber backbone like Comcast has built out. The key limitation is the capacity available between the cable modem and the cable head-end -- that's a tougher nut to crack which carries greater expense.
I do believe that you're invoking the freedom of the Internet incorrectly here. This isn't censorship on the content, this is a limitation on the method of distribution. The freedom of the Internet is indeed a great thing, but there are costs involved in moving bits. The premise of the network has always been that as long as you were willing to pay for the cost of distribution you can pretty much move whatever content you want (subject to legal restriction). The issue here is that people have a very distorted view of how much of the actual transport costs their $42.95/mo covers. The cost model works quite well for normal traffic (surfing, email, youtube, typical downloading) but breaks horribly when heavy P2P loads are applied. There's only 2 ways out of this: reduce consumption or raise prices. If Comcast had their entire user base vote on what should be done, I think you know how that'd turn out. |

(Really?) Re: Net Neutrality is NOT about being protocol neu
Shaping traffic based on bandwidth management needs is one thing.
Providing a bandwidth limit for customer who use more than a certain allotment is tolerable if it's noted in the contract and not applied in a discriminatory way.
Stopping it altogether is denial of service.
Think about the outcome if all ISPs do denial of service based on protocol. Everyone will will start encrypting everyting. What was gained? Nothing. |

I don't want my service adversely affected because other folks are excessive users. As a matter of fact, if they cannot do THIS, then I want the authorities to require Internet service be provided by metered bandwidth -- pay per megabyte uploaded and downloaded. Un-metered service REQUIRES respect for other users of the service. |
