August 21, 2003 — International Internet traffic will grow 67 percent this year, according to a study released this week by TeleGeography, a research division of PriMetrica, Inc. (primetrica.com) According to the study, international Internet traffic does not fully make use of available bandwidth. “Traffic on international links averages only 10 to 30 percent of the available Internet bandwidth,” said Alan Mauldin, senior research analyst with PriMetrica. “However, backbone operators must have sufficient capacity available during the Internet’s busiest periods so that peak utilization does not reach the levels that degrade network performance.” The study also found that the growth of international traffic corresponds well to increases in Internet capacity. “New Internet capacity deployments appear to be driven by reason, rather than optimism,” said Mauldin. “Capacity growth, however, is hardly uniform among providers. While some providers have bulked up their networks in response to traffic demand, others have reduced or eliminated capacity on underutilized links.” The results of the study are based on primary data collected from major backbone operators during early 2003.
