Huawei Unveils Next-Generation DCI Solution

Huawei recently unveiled their next-generation Data Center Interconnect (DCI) transmission solution. It aims to build an ultra-broadband, simplified and intelligent DCI network by leveraging 600G/wavelength, OXC all-optical switching, and Network Cloud Engine (NCE) technologies.

Cloud computing and Big Data are driving a new round of ICT transformation, and data centers (DCs) are becoming new hotspots for investment. Due to space limitations, DCs are often widely distributed. Therefore, DCI is required to provide high-speed and non-blocking data transmission and switching, which forms a logical resource pool to provide consistent cloud services. DCI has contributed to record levels of traffic and posed unprecedented challenges to technological innovation. On one hand, due to an upsurge in traffic between DCs, bandwidth becomes a bottleneck.

On the other hand, ultra-large data backup and fast traffic migration between cloud DCs require network meshing for DCI. Connections in more degrees increase both fiber connections and the complexity of the optical-layer configuration. Furthermore, the dynamic migration of cloud service virtual machines (VMs) constantly changes the DC load. Network traffic becomes dynamic and unpredictable, resulting in frequent service setup and teardown.

To address these challenges, Huawei's next-generation DCI transmission solution integrates three innovative technologies: 600G/wavelength, OXC all-optical switching, and NCE, leading DCI networks into an ultra-broadband, simplified, and intelligent AI era. At the unveiling event, Huawei invited partners German Access, and Netherland's Tallgrass to share their thoughts on DCI development and network construction challenges.
