At MWC Barcelona 2026, China Mobile introduced the GSE-DCI (Global Scheduling Ethernet – Data Center Interconnect) solution. This advancement addresses significant challenges in AI data center connectivity and resource allocation. As AI models grow, single data centers struggle with resource demands. China Mobile’s approach extends infrastructure capabilities from traditional methods to a new Scale-Across model for improved cross-regional computation and scheduling.

The original Global Scheduling Ethernet (GSE) was unveiled in 2023, focusing on intra-data-center performance. The new GSE-DCI connects these networks across centers, crafting a cohesive architecture for distributed AI tasks. The solution responds to four critical challenges: load imbalance across wavelengths, congestion management over long distances, high security overhead, and the integration of computing and networking.

Key innovations include the Multi-wavelength Wide-Area Packet Spraying, balancing loads with ultra-wide channels, and Long-haul Fast Congestion Notification for proactive congestion management. The Ethernet Physical Layer Security offers streamlined data protection, while G-SRv6 optimizes header efficiency for a seamless computing-networking experience.

The prototype supports up to 144 long-haul 800GE ports, a 115.2T switching capability, and can manage over 100 km transmissions. It effectively supports large-scale AI collaborations and diverse resource pooling for learning and inference tasks.

This initiative, contributed by ZTE, marks a significant shift in AI networking capabilities, promising substantial improvements in computational efficiency across multiple data centers.
