Cable Packet Shaping Causing Slowdowns 356

knorthern knight writes "To counter P2P programs that encrypt their traffic to evade detection, Rogers Cable in Canada has apparently started degrading all encrypted IP traffic, according to a post on Michael Geist's blog. How many of you log in to work over a VPN or ssh-tunnel? How many get usenet news or email over an encrypted connection? This could be a problem for Rogers Cable customers. Geist, who teaches at U of Ottawa, has 'been advised that the University computer help desk has received a steady stream of complaints from Rogers customers about off-campus email service.'"

    Cable companies do NOT want you to actually use your Internet connection for anything more than connecting to their webmail, POP, or SMTP servers and surfing CNN, Google, and their billing site.

    We have known for years that they have been overselling bandwidth and then cutting you off when you use more than their "unlimited service" will permit without telling you any concrete numbers of what that is.

    I would guess that very few people use SSH, VPNs, or other encrypted connections that require the speeds to which we have become accustomed. They don't want that 10% of users on their residential network anyway and they will be happy to have you move to their commercial service packages if you so desire.

    I complain that I have to use DSL and pay for land line service that I rarely use but at least my ISP (visi.com) doesn't give a shit what I do (they allow you to run servers, use all your bandwidth, and offer static and reverse).

    I feel sorry for those that don't have more of a choice :(

      Okay, I can see (from their perspective) how you wouldn't want someone who is paying the same as your other customers using 500x the bandwidth that they use. After all, you're paying for the bandwidth.

      So why not simply SEGMENT your network and put those heavy users on their own block? If you're that worried about P2P crap, they're probably sharing amongst themselves anyway. This would make it easier for you.

      So why not offer GRADUATED pricing levels? 2 GB/month for $x. 5 GB/month for $2x. 10 GB/month for $10x. You could even break it down to traffic that stays on your own network and traffic that reaches the Internet.

      The whole thing about the opposition to "Net Neutrality" is about extracting the MAXIMUM profit from the existing infrastructure with the minimum of technological advancement. Fuck that. We have the technology right now to make this a non-issue in almost every case. They just don't want to use it because there is a chance they can make more money by crippling the system.

          No. They want to ADVERTISE an "unlimited" package so that people will leave their graduated plans and come over to the "unlimited" provider.

          Whereupon the "unlimited" provider throttles encrypted communications. And whatever else for someone going over the maximum of the "unlimited" plan.

          [i]Most people want to have unlimited traffic even if they have no concept of the amount of traffic they need.[/i]

          Not really. Most people would rather save a bit of money. So the companies use deceptive advertising.

          I'm saying that we need to force them to get rid of the deceptive advertising. There's no TECHNOLOGICAL reason for it.

          They can sell "unlimited standard usage" packages that throttle connections after 2GB/month.

          They can sell "unlimited gamer" packages that throttle connections after 5GB/month.

          They can sell "unlimited pro" packages that throttle connections after 10GB/month.

          The reason that they don't is that they can save MONEY by being STUPID and selling a single "unlimited" package and fucking with the connections so that things such as encrypted sessions are dead slow. It's about them being lazy. That is it.

        So that if you used 17.79 GB for that month, then your bill would be precisely $17.79.

        It's pretty much the way the long distance companies have being doing it since time immemorial.

        And if upstream bits are more precious than downstream bits, then bill accordingly: Say, $2 per upstream GB per month, and $0.50 per downstream GB per month [or whatever].

        The solution of course is for EVERYBODY to use encryption all the time for everything. Not only would that make ISPs unable to selectively enforce arbitrary levels of service, but it would also make the whole Internet more resistant to malware and spying by governments and corporations. I wonder whether this idea would work technologically? Governments most likely would make it illegal however.

      I would guess that very few people use SSH, VPNs, or other encrypted connections that require the speeds to which we have become accustomed.

      Actually, some major companies out there have several thousand "work at home" employees that are required to use VPN. Most of these people are in sales type of jobs, but plenty others are required to use VPN to connect to Exchange servers to access email from home.

      Considering MS Exchange and dialup don't really mix, these people often have to have broadband to do their jobs efficiently. Seeing how not having VPN with an exchange server is a security risk, I can't really see any alternatives for these work at home types other than to switch to the provider who downgrades them the least.

      Keep in mind these people are often working on company laptops who are locked down completely and couldn't install P2P software even if they wanted to.

        No, not at all. The net neutrality debate is about whether ISPs can throttle content based on the content's particular source, not on the content type.

        Throttling based on content type is called packet shaping, and it's been done in the US and elsewhere for many years. Nothing about the net neutrality legislation would affect that, and anyone who says otherwise is confused or trying to deliberately mislead.

        Throttling based on source, where content of the same type from different sources receives different priorities, is what the net neutrality legislation is about. In other words, any ISP can choose to tone down streaming video traffic so that all their customers can use basic web and email services. No ISP should be able to block video streaming from Google but allow video to stream from Microsoft, just because Microsoft paid them money. (Unless that was clearly advertised to the ISP's customers before they signed up, that is.)

        In this case, it sounds like the ISP is throttling all encrypted content, regardless of its source or destination, so the net neutrality concept doesn't apply at all.

    These days, after all the time to perfect technology and awareness of identity theft and industrial espionage, non-encryped traffic should be banned from Internet at backbone routers. Every ISP can issue you an SSL certificate that indicates the level of verification (possibly none) they performed on your identity. Even with multicast, data can be encrypted with server's private key for which the public key is available to intended recipients, or public. The only exception would be very low powered dumb devices, but those shouldn't be connected to public Internet anyway.

    Use "brownouts" to shape traffic for "fair load" during peak times.

    During non-peak times, when you can carry every bit at maximum speed, do it.

    During peak times when you can't, then, for the next few minutes or hours, cap everyone at X bits per second, Y bits per minute, Z bits per 5 minutes, and so on so the leeches-of-the-moment get throttled down and people putting less immediate demand on the system don't notice any change. X should be as close to the normal maximum as possible. Y should be less than 60X or Z should be less than 300X, or both. This way, people just doing normal web browsing won't be impacted but I'll be slowed down if I dare to download all of kernel.org during a busy period.

    If you combine charging extra for minimum guaranteed per-second bandwidth and charging extra for high-volume-per-month users with peak-demand throttling, then you can raise revenue and/or discourage people from demanding all-you-can-eat lobster buffet service at cup-o-noodles price.

    When people complain about anything related to ISP surveillance, I always wonder how bothered they really are about security. If you're truly interested, you'll use an encrypted network, preferably an onion routing network, because you never know who is watching. My branch of civil rights activism is highly controversial and generally misinterpreted, so I always make sure that I route my traffic in an encrypted form through my ISP's routers

    Sadly, some people really don't understand that the internet is NOT anonymous and that you must use other measures to achieve a reasonable degree of security.

    I'm no fan of cable companies, but someone has to speak up about the problems associated with P2P. I'm aware of some educational institutions that saw their newly upgraded networks come to a complete grinding halt - simply because of P2P sharing. They had no choice but to shape their traffic so that other business could get done. They didn't ban it or shut it off. They simply said X amount of our bandwidth can be used for it during business hours and Y amount at other times. And now look what's happened: P2P clients have deliberately foiled such attempts by encryption. Great. Now those institutions will be crippled once again by dorms full of students sharing their entire music collection to the world, many not even aware that they are doing it.

    I don't want to kill P2P. I am no fan of cable companies or the RIAA or the MPAA. But don't blame network admins when they have to fight back on this stuff!

      Fine. So put intelligent rate or bandwidth caps on and be upfront about that policy (this goes both for cable providers and universities). You used to be able to build networks with the assumption that most people wouldn't be transferring data most of the time. This simply isn't true any more.

      This can be solved easily.

      Just auth your users (whether it be on a physical port or otherwise), and tell them you're providing them X GB per month, and Y GB per day, before they're tripped down to 56k-connection-land. If they're hitting their daily/monthly quota regularly, lower the quota for them permanently. Of course you need to have a process in place to grant higher quotas to those who need them, or investigate why someone's hitting their quota all the time if they're on vacation, etc.

        I like this line of thinking, however, two small points must be made:

        1. There's no way for the IT department to say "sorry, you're in 56k land now" when the student is complaining to his/her parents/dean/professor/pope that they can't get their homework done on our network even though they pay $20k a year in tuition.

    Telecommuting is too popular for this tactic to work in the US. There are some very powerful companies that have a vested interest in VPNs being reliable and responsive. How many of you think Cisco would let ISPs get away with this? Sure, Cisco sells lots of expensive hardware to ISPs, but they also sell a lot of hardware and software to businesses and consumers so that VPNs can be established.

    Also, I know that many employees of my local and state governments use VPNs daily. If their VPN connections get any slower, they will be well-nigh unusable. This is essentially a lower-stakes version of NTP wanting to cripple every congressman's BlackBerry. Our monopolies seem to be forgetting rule #1: don't piss off your regulators!

Not to mention, frequent disconnects, busy trunks in the evenings, etc..

    How pathetic.

    These companies have no interest in providing a quality service, their only interest is milking their customers for as much as possible as long as they can.

      You answered your own question.

      The entire telecom industry is an absolute scam. Nothing comes close.

      Go work in telecom for a while and you will be amazed. The focus is never on providing service or creating new products. It's always "how can we maximize return on our existing customers and infrastructure" and "how much can we leverage this incremental improvement"?

      Invent something that costs 1/1000th of a cent to deploy and use? Let's price it at 10cents per use.

      Handheld makers invent a technology that lets customers play music on their phones? How can we block them from loading their own music so that they must buy it through our storefront?

      Convert your network to be digital, so now you can carry data as well as voice? Oh.. hold on there. It costs us less to move data than voice, but we should be charging 100-200 times more for this great new feature.

      Don't let any ISVs run a service over your network. That's revenue that you should be getting from your customers directly. Yes, it would make our service more useful, but you can't have anyone else interacting with your customers.

      I could go on and on for days (and I was only in it for four months!) It's an absolute scam.

      Heath-care and banking are just blips on the radar compared to the telecom scam Goliath.

        • WiFi is a way around the last-mile monopoly (which, as you say, is what they're fighting.) Given a dense enough distribution of access points, it can certainly compete with the cable/DSL folks in that arena. However, even if WiFi is successful there (and it would probably take an act of Congress at this point given the resources the telcos and cable companies are diverting to stop it) that still leaves the backbones, and I don't know what would replace all that fiber and the corporations that own it.

    I stayed at a Marriott hotel last week in Long Beach that used stayonline.net as there ISP, and the network was horrid. My colleague figured out after two days that the reason he was banned from the network was for using a non-US encryption standard for his SSH. Total bull. Also, file transers over a few meg seemed to be throttled like mad, making it almost impossible to upload pictures until after I got back home.
