  • Achieve a network of low latency (via Access Point: about 260 microseconds one-way (*1), via Co-Location Area: about 32 microseconds one-way (*2))

Reliability (secure 99.999% availability)

  • Construct a robust optical fiber ring network with totally separate backup routes and 99% buried cables (in preparation for large-scale earthquakes and such wide-area disasters)
