NTT has conducted low-latency data center-to-data center light-based photonics tests in the UK and US, claiming latency of less than 1 millisecond between facilities almost 90km apart.
In the UK, two data centers around 100 km apart communicated via IOWN APN connection with a round trip of 1 millisecond or less. Similar performance was recorded in the US. NTT said the links make multiple data centers functional as an integrated IT infrastructure logically equivalent to a single data center. This enables customers to meet their needs in use cases where low delay is highly required, such as real-time AI analysis and in the finance sector.
“The APN delivered very low latency required by current and emerging use cases. These include distributed, real-time AI analysis, such as industrial IoT and predictive maintenance, smart surveillance systems, smart grid and energy management, natural disaster detection and response and more,” the company said. “The goal of this initiative is to transform geographically distributed IT infrastructure into the functional equivalent of a single data center.”
