The evolution of data centers' architecture and networks has been driven by cloud computing, 4/5G core networks virtualization, 5G services and artificial intelligence. Future data centers are evolving from centralized data centers to “data center clusters”. Therefore, interworking of “data center clusters” becomes more important than ever. The requirements of quality, bandwidth, latency and reliability of Data Center Interconnection (DCI) networks need to be met. Taking into account the characteristics of the data center architecture and traffic, several directions in next-generation DCI network have been pointed out, including SRv6-based efficient IP connection, hard network slicing supporting multi-services, ultra-low latency, software defined network-based strong control and high reliability. Neither traditional Ethernet switches/routers nor optical interconnection networks can easily meet these requirements simultaneously. Therefore, a completely new technology - Metro Transport Network (MTN) has been proposed. It brings the TDM characteristics based on the Ethernet systems and is capable of hard network slicing, ultra-low latency and ultra-high time synchronization accuracy. In this article, the MTN concept, ITU-T standardization work and its advantages for DCI are introduced. A field trial of an interconnection of three data centers via a commercial MTN network was presented as well. Virtual machine migration, dual-active storage backup and file delivery services were successfully implemented during the field trial. The results have verified that MTN interconnections can achieve hard slicing and a significant reduction of latency, jitter and switching time, which well match the requirements of next-generation DCI networks.
