Professor Naoaki Yamanaka of the Faculty of Science and Technology at Keio University is conducting research on highly fault-tolerant next-generation optical networks aimed at application in the era beyond the currently available 5G services (Beyond 5G). As part of this research, he has successfully conducted an experiment to improve the fault tolerance of next-generation Ethernet, which flexibly allocates communication capacity using a massively parallel optical transmission network. He has also successfully demonstrated a new optical network operation concept that can maintain the expected value of communication capacity even in optical networks with increased failure risk by dynamically allocating multiple communication paths based on failure prediction. This is made possible by the ability to secure multiple paths on a massively parallel optical transmission network and to probabilistically determine the available communication capacity based on a failure model that accounts for equipment degradation over time.
An experimental demonstration of this research will be presented at KEIO TECHNO-MALL 2021, to be held online on Friday, December 10. We invite the press to cover this event.
