Lucent Technologies' chairman Richard McGinn said a "network of networks" was needed to cope with booming traffic demands, and optical technology would be the key.
Speaking at the Networld+Interop show in Atlanta this week, he pointed out that new optical technologies allowed "400Gbits on a single fibre, with up to terabits by 2000. That's 2,000 times the traffic of two years ago."
That power will be needed, with 37 million people a day accessing the Internet, a figure expected to treble each year for the foreseeable future.
Other important carrier level technology improvements will centre on wireless networks, and merged IP/ATM or IP/Sonet structures, said McGinn.
