MUFG Bank and NTTDATA worked with the IOWN Global Forum to create use cases and Reference Implementation Models demonstrating how APN and Optical DC networks can transform financial systems. A white paper was published detailing these innovations and their applications. MUFG Bank, NTTDATA, and NTT West tested their ideas through pilot experiments, yielding two major outcomes: real-time database synchronization reduces reliance on complex backup frameworks, and virtual instances enable seamless Data Center transitions without downtime, enhancing efficiency. This allows financial institutions to meet evolving customer demands more effectively. Research is ongoing to integrate Optical Network technology with OCP hardware to address latency, bandwidth, and prioritization issues for NIC-to-NIC communication. By combining software, hardware, and networks, NTTDATA aims to create smarter, more resilient financial systems.
