It hardly needs to be emphasized that video is now the major components
of traffic on the Internet, with three-screen capability—
delivered to TV sets, computers, and cell phones—an overriding goal
of the computing, communication, and entertainment industries.
This raises a number of interesting issues. One is the impact
that all of this video will have on the bandwidth required for
the Internet. We are still a long way from having enough deployed
capacity in the Internet to transmit entertainment video
to everyone who watches TV or rents DVDs today. Not only
is this driving demand for more network capacity, but new
network architectures with names such as content-centric
networking are also being proposed.
