Qwilt: "Open Transparent Caching" vs. Content Providers' "Black Boxes"

Some quotes from a GigaOm post with Qwilt's CEO, Alon Maor [pictured]:
  • Since launching Qwilt in 2011, I’ve seen online video grow to be one of the hardest challenges network operators face today. In my role as CEO, I’ve overseen Qwilt’s engagements with more than 150 network operator customers worldwide - some of whom are experiencing 90% growth of video year over year which translates to 60% growth of their overall internet traffic [see "[Sandvine] NA Cord-Cutters Stream 3 Hours of Video a Day" - here]. This presents not only a tremendous opportunity, but also its own set of challenges.
  • .. content providers like Netflix and Google now regularly publish ISP rankings that expose both the best and worst performing ISPs by region .. Ultimately, these rankings ensure accountability lies with the network operator instead of the content provider when the consumer’s experience is unsatisfactory [not always .. - see "Netflix - Speed to Comcast Customers Continue to Surge" - here] and network performance is the cause.
  • A number of US cable operators, including Mediacom Communications [here], have deployed transparent caching technology to leverage the value of caching video deep in their networks, close to consumers.

  • Transparent caching deployed inside operator networks embraces an open architecture. This infrastructure is transparent, universal, neutral, trusted and secure. This open architecture stands in contrast to the closed cache systems operated by some content providers today which appear as black boxes to network operators [see "Netflix CDN Customers have More Fun" - here].

    These closed caches systems address only one content provider at a time and, therefore, reduce the ability of operators to optimize traffic on their networks. So, for example, content streamed from Content Provider A will not be cached by Content Provider G’s closed cache.
  • Content providers are considering further steps to obscure their content. Indeed, last November, Eric Schmidt, Google’s executive chairman said, “Encrypting everything could end government censorship for a decade.”

  1. The internet is going into HTTPS, Youtube already started to stream video over HTTPS, Facebook is HTTPS and all the rest will follow shortly. Transparent caching technology is already dead in the water. The future is in these "Private Box's" or actually the future will be in ISP's creating there own private cloud hosting on it these CDN VM's for money... this way both the ISP/Operator and the CDN's are making money and the subscribers are happy... BTW this is one of the first use cases for NFV

    1. "The internet is going into HTTPS" Do you have figures about this ? HTTPS traffic seems still low in westerns ISPs...

    2. Anonymous is right, sad but true unless idustry standard is pushed towards generic transparent cache solutions, this will be the end of it.
      it's just matter of time before everything goes https. vimeo, youtube and facebook are all https. On top of that, company like google tries hard to avoid 3rd party to cache their content by
      constantly changing their URL format and video id.
