Looking for a concise overview of how Internet architecture has evolved and a principled discussion of the public policies that should govern the Net going forward? Then look no further than Christopher Yoo‘s new book, The Dynamic Internet: How Technology, Users, and Businesses are Transforming the Network. It’s a quick read (just 140 pages) and is worth picking up. Yoo is a Professor of Law, Communication, and Computer & Information Science at the University of Pennsylvania and also serves as the Director of the Center for Technology, Innovation & Competition there. For those who monitor ongoing developments in cyberlaw and digital economics, Yoo is a well-known and prolific intellectual who has established himself as one of the giants of this rapidly growing policy arena.
Yoo makes two straight-forward arguments in his new book. First, the Internet is changing. In Part 1 of the book, Yoo offers a layman-friendly overview of the changing dynamics of Internet architecture and engineering. He documents the evolving nature of Internet standards, traffic management and congestion policies, spam and security control efforts, and peering and pricing policies. He also discusses the rise of peer-to-peer applications, the growth of mobile broadband, the emergence of the app store economy, and what the explosion of online video consumption means for ongoing bandwidth management efforts. Those are the supply-side issues. Yoo also outlines the implications of changes in the demand-side of the equation, such as changing user demographics and rapidly evolving demands from consumers. He notes that these new demand-side realities of Internet usage are resulting in changes to network management and engineering, further reinforcing changes already underway on the supply-side.
Yoo’s second point in the book flows logically from the first: as the Internet continues to evolve in such a highly dynamic fashion, public policy must as well. Yoo is particularly worried about calls to lock in standards, protocols, and policies from what he regards as a bygone era of Internet engineering, architecture, and policy. “The dramatic shift in Internet usage suggests that its founding architectural principles form the mid-1990s may no longer be appropriate today,” he argues. (p. 4) “[T]he optimal network architecture is unlikely to be static. Instead, it is likely to be dynamic over time, changing with the shifts in end-user demands,” he says. (p. 7) Thus, “the static, one-size-fits-all approach that dominates the current debate misses the mark.” (p. 7) Continue reading →
