1. Background

The financial industry is experiencing rapid digital transformation, driving the need for faster and more sophisticated transactions. Algorithmic trading and other latency-sensitive trading, such as High Frequency Trading (HFT), as well as real-time transaction, are on the rise, making ultra-low latency networks essential for financial institutions to maintain a competitive edge—where even milliseconds can impact trading outcomes. With APN InterLink, financial institutions can accelerate their digital transformation and strengthen their foundation for innovation, including collaborative development and AI-driven initiatives.

For mission-critical operations, robust disaster recovery systems are vital to ensure business continuity in the face of severe disruptions. By leveraging IOWN^® APN, organizations can achieve efficient, seamless data transmission between geographically distributed sites, significantly enhancing the reliability and operational efficiency of large-scale disaster countermeasures.

   The interconnection between NTT Com Asia’s Financial Data Center and Tai Po Data Center via APN delivers an ultra-low latency network.
