One Movie: You Blow Your Monthly Data Plan

Something's gotta give here: Akamai has rolled out a high definition television delivery service, capable of delivering a two-hour feature-length movie encoded at a bit rate of at least 6-8 Mbps, with a resultant file size of 5 Gbytes to 8 GB. For those of you with some popular wireless broadband accounts, that's pretty much your "acceptable use" level of monthly consumption of data! And that's just your problem.

Assume the same bit of content were delivered to enough households to create one Nielsen ratings point. That's 1,102,000 households. Which means the delivery networks would require 6.6 Terabits per second of sustained bandwidth, assuming zero latency and zero network congestion!

I don't care who you are, your pipes are getting to be too small. Local area network bandwidth at enterprises is growing smartly, but consumer bandwidth won't be far behind, if in fact consumer bandwidth does not soon eclipse enterprise bandwidth in at least the downstream direction.

One HDTV movie. Two hours. Your whole monthly acceptable use consumption. Obviously there's not enough bandwidth.
