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.

From: "Mark Tinka" <mark.tinka@seacom.mu> 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 bandwidth"? Which social media platform is it 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.
