Approach to New Generation Network for Various Problem‐Solving
Rapid Increase of Traffic
Ultrahigh‐speed, high‐capacity and efficient photonic network is a must to hold traffic whose amount is expected to reach Pbit/s in the 2030s.
Power Consumption Increase in Info. & Telecom Network Equipment
‐ Limitation of the current mixing technology of electricity and photonic by 2020.
‐ Implementation of all‐photonic technology is a must in/after 2020.
Problems of Internet – Too Complicated & Structural Failures
‐ Impossible to build new functions.‐ Impossible to provide services to supportthe future society.‐ Now is the time to re‐create from a clean slate.
