The annual survey, entitled "Global Internet Geography," indicates that utilization rates of Internet backbones have been creeping up over the past year. As a result, service providers are likely to resume adding capacity to their international backbones in 2005, having held back on doing so in 2004.
"The case is particularly acute in Asia, where peak utilization on international backbones into Chennai and Shanghai exceed 80 percent (compared to a global peak of around 40 percent). No wonder so many international network managers complain about QOS into these places," writes Jason Kowal, Telegeography's president, in an email to Light Reading.

In order to add capacity to their networks, service providers will probably have to light additional wavelengths in DWDM gear, and install more Sonet/SDH equipment and routers. There's plenty of unlit capacity left in sub-sea cables, according to Kowal. "It's all about traffic growing really fast and bandwidth coming too slow," he adds.
