How does Netflix Optimize Video?

With Netflix responsible for "up to 29% on North American Internet traffic" (Sandvine, here) - managing the load created by its content delivery should be a very important task for ISPs and carriers.

Operators may use network based optimization, or data caps (here) to mange to load - but it appears the Netflix is putting a significant effort to help them as well, and always deliver the most optimized content to the subscriber, by preparing it in advance.

Kevin McEntee (pictured), VP Digital Supply Chain, Netflix explains in a blog post and a short video (here) the video supply chain - the steps taken to prepare a movie or TV episode for streaming. included is a step in which Netflix transcodes the content to multiple devices/ bit rates. This creates 120 different downloadable per movie!.
