Proposals to subject the Internet to a centralized, international governance structure would constitute a major setback for broadband Internet expansion and innovation, warned FCC Chairman Julius Genachowski at the Futurecom conference in Rio de Janeiro on Wednesday. Genachowski delivered his remarks in anticipation of the upcoming International Telecommunications Regulations (ITR) treaty negotiations that are scheduled to take place in Dubai in December. Delegates to the Dubai conference are slated to discuss the first planned modifications to the ITR treaty since 1988. Lawmakers from both political parties have joined with members of the Obama Administration, U.S. government officials, and industry executives in voicing concern with proposed amendments to the ITR treaty, championed principally by Russia and China, that would grant the International Telecommunications Union (ITU) central governance authority over the Internet and cyber security. U.S. officials have also taken issue with proposals that would mandate a “sender pays” regime for the exchange of traffic across Internet networks. Calling on nations worldwide to support the current multistakeholder model of Internet governance, Genachowski argued that the centralized governance plan “will increase uncertainty and raise costs for online innovators everywhere and could significantly limit access to Internet content and applications for consumers in developing countries.” Describing the upcoming Dubai conference as “a crossroads for the Internet,” Genachowski maintained that nations should instead “embrace commercial arrangements, remove barriers to private investment, vigorously promote competition, and protect unfettered access to information.”
