Oh, I'm not proposing symmetrical connectivity at all. I'm just supporting the argument that in the context of this discussion I think it's silly for a residential ISP to purport themselves to be a neutral carrier of traffic and expect peering ratios to be symmetric when the overwhelming majority of what they're selling (and have been selling for over a decade) is asymmetric connectivity. Their traffic imbalance is, arguably, their own doing.

How residential ISPs recoup costs (or simply increase revenue/profit) is another question entirely. I think the most insightful comment in this discussion was made by Mr. Rick Astley (I assume a pseudonym), when he states that ISPs have several options to increase revenue A) Increase price of their product, B) Implement usage restrictions, or C) Charge someone else/Make someone else your customer. I think he successfully argues that option C may be the best. As we've seen, the wireless market in the US went for option B. We've yet to see where the wireline market will go.

Of course, the market would ideally keep ISPs' demands for revenue/profit in check and we'd all reach a satisfactory solution. One of the arguments, one I happen to support, in this thread is that there is not a free market for internet connectivity in many parts of the US. If there was, I believe Comcast would be focusing on how to provide a balance between the best product at the lowest cost and not on how they can monetize their paying customers in order to increase profits. I appreciate honesty; When a service provider advertises X Mbps Internet speeds, I expect they can deliver on their claims (to the whole Internet, and not just the portions of it they've decided). I understand congestion, overselling, etc. But choosing which portions of the internet work well and which don't is a lot more like censorship than service.

Blake,

You're absolutely correct. The world adapts to the reality that we find ourselves in via normal market mechanics. The problem with proposing that connectivity for residential customers should be more symmetrical is that its expensive, which is why we as operators didn't roll it out that way to start. We also don't see consumer demand for symmetrical connections and with the decline in peer to peer file sharing we've actually seen a decrease the ratio of used upstream bandwidth (though not a decrease in absolute terms).

I would like to deliver symmetrical bandwidth to all consumers just so those few customers who need it today would have lower bills but trying to justify that to our CFO without being able to point to an increase in revenue either because of more revenue per sub or more subs is a very tough task. I don't believe my situation is uncommon.

    Thanks for the insight Scott. I appreciate the experience and
    point of view you're adding to this discussion (not just the
    responses to me). While I might be playing the devil's advocate
    here a bit, I think one could argue each of the points you've made
    below.

    I do feel that general usage patterns are a reflection of the
    technologies that have traditionally been available to consumers.
    New uses and applications would be available to overcome hurdles
    if the technologies had developed to be symmetrical. I'm not
    saying that the asymmetrical choice was a bad one, but it was not
    without consequences. If residential ISPs sell asymmetric
    connections for decades, how can the ISP expect that application
    developers would not take this into account when developing
    applications? I don't think my application would be very
    successful if it required X Mbps and half of my market did not
    meet this requirement. Of course content/service providers are
    going to tailor their services based around their market.

        Blake,

        I might agree with your premise if weren't for a couple of items.

        1)  Very few consumers are walking around with a HD or 4K
        camera today.

        2)  Most consumers who want to share video wouldn't know how
        to host it themselves, which isn't an insurmountable issue but
        is a big barrier to entry especially given the number of
        NAT'ed connections.  I think this is much more of a problem
        than available bandwidth.

        3)  Most consumers who want to share videos seem to be
        satisfied with sharing via one of the cloud services whether
        that be YouTube (which was created originally for that use),
        Vimeo, or one of the other legions of services like DropBox.

        4)  Finally, upstream bandwidth has increased on many/most
        operators.  I just ran the FCC's speedtest (mLab not Ookla)
        and got 22 mbps on my residential cable internet service.  I
        subscribe to one of the major MSOs for a normal residential
        package.

            Certainly video is one of the most bandwidth intensive
            applications. I don't deny that a < 1 Mbps video call is
        both less
            common and consumes less bandwidth than an 8Mbps HD stream.
            However, if Americans had access to symmetric connections
        capable
            of reliably making HD video calls (they don't, in my
        experience),
            we might be seeing video calls as a common occurrence and
        not a
            novelty. I think the state of usage is a reflection on the
            technology available.

            If the capability was available at an affordable price to
            residential consumers, we might see those consumers stream
        movies
            or send videos from their home or mobile devices via their
            internet connection directly to the recipient rather than
        through
            a centralized source like Disney, NetFlix, Youtube, etc. Video
            sharing sites (like youtube, vimeo, etc) primary reason for
            existence is due to the inability of the site's users to
            distribute content themselves. One of the hurdles to
        overcome in
            video sharing is the lack of availability in affordable
        internet
            connectivity that is capable of sending video at reasonable
            (greater than real time) speeds.

                Blake,

                None of those applications come close to causing
        symmetrical
                traffic patterns and for many/most networks the upstream
                connectivity has greatly improved.  Anything related
        to voice
                is no more than 80 kbps per line, even if the SIP traffic
                isn't trunked (less if it is because the signaling data is
                shared).  Document sharing is not being impinged, on my
                residential account right now I've uploaded about 30
        documents
                this morning including large PDFs and Power Point
        presentations.

                Off site back up is one use that could drive traffic,
        but I
                don't believe that the limiting factor is bandwidth.  We
                looked at getting into that business and from what we
        saw the
                limiting factor was that most residential and SOHO
        accounts
                didn't want to pay enough to cover your storage &
        management
                costs.  In our analysis the impact of bandwidth on the
                consumer side adoption was basically zero.  There is no
                expectation that back ups run instantly.  Having said
        all of
                that, even if hosted back up became wildly popular
        would not
                change the balance of power because OTT video is both
        larger,
                especially for HD streams, and used much more frequently.

                            While that is true a lot of the time
        (especially
                for eyeball
                            networks), it is less so now due to social
        media.
                Social
                            media forces the use of symmetric
        bandwidth (like
                FTTH),
                            putting even more demand on the network,

                        Oh yes; clearly, Twitter will be the end of L3.

                        :-)

                        Could you expand a bit, Mark on "Social media
        forces
                the use
                        of symmetric

        that
                you think
                        has a)
                        symmetrical flows that b) are big enough to
        figure into
                        transit symmetry?

                    Applications like Skype and Facetime (especially
                conference calls)
                    would be one example where an application benefits
        from
                symmetric
                    (or asymmetric in favor of higher upload speed)
        connectivity.
                    Cloud office applications like storage of documents,
                email, and
                    IVR telephony also benefit from symmetrical
        connectivity.
                Off-site
                    backup software is another great example. Most
        residential
                    connections are ill suited for this. I believe these
                applications
                    (and derivatives) would be more popular today if the
                connectivity
                    was available.
