    Distinction Without a Difference - The assertion that a position is different from another position based on the language when, in fact, both positions are exactly the same -- at least in practice or practical terms.

    To clarify once again. The distinctions drawn are not based on nomenclature. There are specific and important technical differences which have real impact on the discussion.

    As I read your post again, I'm sorely tempted to respond in kind. However, I understand that you thought I was assigning ignorance of this particular area of knowledge to you as an insult (although you did do so in your original reply -- note that I simply repeated what you said first), rather than as a simple statement of fact. In your position, I would likely have responded similarly.

    Your provided links show that "packet sniffing" and "traffic flow analysis" are not different concepts in practice. The difference is in how the collected data is analyzed or for what purpose.

    This is an incorrect conclusion. Packet sniffing and Netflow analysis are significantly different in both theory and practice, both from the standpoint of data collected, as well as the method(s) of collection. Granted, if you are sniffing packets, you can perform a similar analysis, but that's both completely impractical (and in the context of the research) self-defeating. Attempting to sniff all packets off an IX Node requires mirroring all packets. Which would almost certainly cause serious congestion problems and be detected almost immediately. Collecting Netflow data from same wouldn't have a noticeable effect on the IX Node's network links.

    Just to clarify that point. Collecting Netflow (or similar management protocol) data is significantly and demonstrably different (in the attack mechanisms posited by and the methodology employed by the researchers) in both theory and practice.

    Yes, in a scenario with network links that carry much less data and both endpoints are known, packet sniffing and Netflow data collection *can* provide similar analytical results (I've done both myself), identifying data flows across large portions of the Internet (i.e., encompassing all or at least a significant fraction of Tor entry nodes -- in that the goal is identification of a device at an unknown location anywhere in the world) is a completely different animal.

    I could go on, but those are the high points. The above should be obvious to anyone who has a reasonable amount of experience with IP networking. Perhaps I should have been more explicit, but given that this is a tech site and the article concerns a scholarly paper about networking, I assumed a certain level of working knowledge. My mistake.

    There is no need to be rude or presumptive about my level of education. I shall explain what I meant in more depth to clear up any misunderstandings. OP said: "So if you can spy on the traffic from the user to the tor entry node, and can spy on the traffic leaving the tor exit node at the same time... then you can tell that the traffic you saw going to the entry node is linked to the traffic leaving the exit node" You said: "If you can correlate the server-->exit node flow to a specific entry node-->client flow, you've just identified the client outside of Tor."

Your provided links show that "packet sniffing" and "traffic flow analysis" are not different concepts in practice. The difference is in how the collected data is analyzed or for what purpose. For the purposes of this discussion where analysis of collected packets is for identical purposes, this is also a distinction without a difference. "A packet analyzer...is a computer program or a piece of computer hardware that can intercept and log traffic passing over a digital network or part of a network." "NetFlow is a feature that was introduced on Cisco routers that provides the ability to collect IP network traffic as it enters or exits an interface." If you feel I have misinterpreted your statements, I would appreciate additional feedback.

    My points were literal, rather than pejorative. Sniffing packets is gathering the *actual* packets. Netflow collects statistics about packets being transmitted/received. Do you see the difference?

    GP stated "Good luck being able to sniff traffic on *both* ends." Firstly, traffic isn't being "sniffed." Secondly, With Netflow, it's not necessary to have packet sniffers on the specific links used in order to gather packet statistics.

    What is more, since context is everything, GP was responding to my assessment of the paper (you know, the point of the article) and misunderstood the methodology used by the researchers. I explained.

    If I (here and in my original post) have been unable to explain to you both the difference between packet sniffing and Netflow analysis and/or why GP misunderstood the methodology employed by the researchers, I suggest you read the paper yourself.

    TL;DR : Packet sniffing != Netflow. Methodologies have impact on results and should be understood.

    Comcast / AT&T / etc absolutely do not want this. Being classified as common carriers is about the worst business move they could forced into. Why? Because Title II equates to a lot of regulations - that's what Title II is. Title II is why phones are heavily regulated by taxes, where they must be laid, and other regulations that have been in place since 1934 (and updated in 1993). If Comcast / AT&T / Verizon / etc get lumped into Title II, then it'll cost them millions of dollars in employee costs, plus any additional costs from possible additional regulations that may be imposed now or down the road.

    Bzzt! wrong. I don't believe you are who you say you are. If you were, you'd know that up until 2002, cable internet services were classified as "common carriers" under Title II. The same was true for DSL providers until 2005.

    As I recall those guys did just fine. the regulations aren't as onerous as you're making them out to be and the FCC has wide latitude (which it has used repeatedly) to waive portions of Title II for specific reasons.

    Also, the update that you mention was the "Telecommunications Act of 1996," and was not passed three years earlier. Yes, there will be more regulation than there is now, but that regulation, made for more competition, more innovation and better service. That's what the FCC is *supposed* to do.

    There IS still the debate on whether Comcast is genuine on wanting net neutrality. I've been told that there's more to the Netflix story than is being told (and that Comcast was only looking to be paid for the bandwidth consumed), but I don't have enough evidence to substantiate this either way. We currently mostly have net neutrality now, without regulation, due to market forces.

    That ship sailed, friend. Comcast Is already paid for that bandwidth -- by it's own customers. That data was requested over links that were paid for by Comcast's customers as a pipe to bring them data from the Internet. Netflix tried to deliver the data requested to Comcast's customers Comcast was either unwilling or unable to do so. Comcast sold services and then claimed it couldn't deliver those services unless it was paid more.

    I'll be the first to admit that Comcast is perhaps one of the most vile companies that currently exist in the US. However, what we have now mostly works *without* additional regulation. I'm fearful what additional regulation may do to this - our government doesn't have a great history of making things better with more regulation.

    Just be sure you look through the politics and look at the actual arguments. This isn't about Net Neutrality. Rather, Obama is using Net Neutrality as a keyword to push for Title II. And *that* won't end well.

    You are correct. Title II reclassification by itself is not "network neutrality." Network Neutrality is dumb pipes providing unrestricted IP (v4 and v6) connectivity. Full stop. Title II reclassification is just a small part of that. Much more needs to be done to effect and ensure real network neutrality. It does not exist on Comcast, Verizon, AT&T and most of the other big ISPs. I know, because I actually have (at least as far as I can tell) an ISP that gives me a "dumb pipe providing unrestricted IP (v4 but not v6 yet) connectivity. Full stop."

    The issues of surreptitious throttling, abusive terms of service and lobbyists (probably guys just like you) taking to the statehouses to cripple or outright ban competition for the big ISPs is a much bigger part of the problem.

    Full Disclosure: I am a network ops engineer for Comcast.

    Anyone who believes that buying private links into a providers network is the same as your traffic getting paid priority knows jack shit about network ops. In the case of Comcast, Netflix traffic gets no special priority once it's on the internal network. The direct links simply lets them bypass the naturally occurring bottlenecks that occur at internet peering points.

    Now I'm sure a bunch of people (who are not network engineers) are going to argue over the wording and philosophy as to whether or not buying paid links into a providers network constitutes priority or not. It's not. In network operations, priority is a very specific concept. It means that you treat one class of traffic better than others, usually to the detriment of other classes of traffic. As an example, e911 voice traffic has the *highest* priority on the Comcast network.

    Comcast does not treat Netflix traffic any better than anyone else's traffic. Nor is it treated any worse. It is forwarded as Best Effort within the Comcast network.

    The only difference that buying direct links in meant was that they got to skip the congestion in the peering points. Comcast has alot more bandwidth internally and once traffic makes it into the network, congestion is not usually a problem (things do break, redundant links become saturated, etc. It's a big network, but in normal operation mode, congestion doesn't exist). What little prioritization we do has alot more to do with latency than with congestion (ie, your phone call is more important than your massive porn transfer, since voice is alot more sensitive to delay than bulk data transfer).

    All of what you say is normal and reasonable, although I assume you don't honor QoS tags from VOIP traffic that originates outside your network. Which isn't a criticism, no one does. As for the paid links, that's not an issue, IMHO. I would point out that Comcast did refuse to install netflix CDN/caching servers, which would likely have resolved the issue much more cleanly for everyone. But the cable TV and content divisions must be "protected."

    What's an issue for me (NB, I'm *not* a Comcast customer, you guys aren't even near me) is the surreptitious throttling of P2P and VPN traffic (and then lying about it), blocking port 25 and abusive (no servers, outrageous prices for static IPs if you guys even give those out at all on consumer links, I'm sure I could come up with a few more if I was a customer.) terms of service, not to mention the "retention" and upselling tortures your customer service reps put consumer-grade customers through.

    At my previous employer we had a (not by choice -- we needed a redundant provider and you were it) Comcast Business link and, while the link was fairly stable and we got the speeds we paid for, anytime there was a problem (which wasn't often, in your defense) the tech support guys were worthless.
