• The nearly 64 exabytes of global IP traffic per month projected for 2014 is equivalent to 16 billion DVDs, 21 trillion MP3s, or 399 quadrillion text messages.
• By 2014, the highest IP-traffic generating regions will be North America (19.0 exabytes per month), Asia Pacific (17.4 exabytes per month), Western Europe (16.2 exabytes per month) and Japan (4.3 exabytes per month). Asian traffic altogether will be highest in the world.
• The fastest growing IP-traffic regions for the forecast period (2009-2014) are Latin America (51% compound annual growth rate, 7.9-fold growth), the Middle East and Africa (45% CAGR, 6.5-fold growth), and Central Europe (38% CAGR, 5.1-fold growth).
All these changes, with larger volumes and changing user needs, require network providers and managers to prepare for new and unexpected demands on their infrastructure and operations.
Pepper said wireless networks are going to need more spectrum, "and fiber to every antenna, fiber to every village -- a T-1 connection to the antenna is not going to cut it."
Ethical issues emerge
Keynote speaker David Suzuki, a Canadian ecologist, noted that humans are now the most numerous species of any mammal in the world. "There are more humans than rats, or rabbits," he said. He warned that exponential growth of human demands on the planet has led to climate change, and could lead to potential ecological disaster.
Suzuki challenged communications industry professionals to apply their insights and innovations to more informed policies and practices. The conference itself featured a number of presentations focused on "green IT." Another focus was economic development for underserved areas of the Pacific, especially island nations and rural populations, through broadband projects.
Communications ethicist Thomas Cooper presented research showing that ethical considerations are far more prevalent in industry discussions now than they were in the 1990s. Cooper reported the top five communication ethics areas observed, in order: privacy; information security; freedom of information and censorship; digital divide; intellectual property and patent protection.
Cooper emphasized that communications ethics involves not only "red light" issues such as regulating negative impacts of invasion of privacy and cybercrime, but also "green light" issues such as education, telemedicine and e-democracy. Cooper forecast that the communications industry will continue to face these intertwined challenges, and urged PTC delegates to be ready to participate in both.
