From YouTube, IPTV, and high-definition images, to “cloud computing” and ubiquitous mobile cameras, 3D games, virtual worlds, and photorealistic telepresence, the new wave is swelling into an exaflood of Internet and IP traffic.

Bret Swanson & George Gilder estimate that by 2015, U.S. IP traffic could reach an annual total of one zettabyte (10²¹ bytes), or one million million billion bytes.

“The U.S. Internet of 2015 will be at least 50 times larger than it was in 2006. Internet growth at these levels will require a dramatic expansion of bandwidth, storage, and traffic management capabilities in core, edge, metro, and access networks. A recent Nemertes Research study estimates that these changes will entail a total new investment of some $137 billion in the worldwide Internet infrastructure by 2010. In the U.S., currently lagging Asia, the total new network investments will exceed $100 billion by 2012.”
