Core Value: Empowering Urban Digital Transformation
In recent years, urban digital transformation has been steadily advancing. Metropolitan Area Networks (MANs) serve as the solid foundation for this transition, providing high-speed, stable, and secure connectivity to support technologies such as cloud computing, big data, AI, and the Internet of Things (IoT). MANs play a vital role in smart city development. In smart transportation, they enable real-time data transmission to support intelligent traffic signal control. In smart healthcare, they allow for remote consultations and data sharing. In smart education, MANs enable online teaching, breaking geographic barriers. The architecture and capabilities of MANs have led to the emergence of innovative services such as smart homes, enterprise cloud services, and edge computing, invigorating market vitality. At the same time, advanced technologies ensure network security and safeguard key urban information infrastructure and data assets.

Technical Features: Innovation-Driven Development
- IPv6+ technology brings numerous innovations to MANs. For example, SRv6 enables flexible construction of low-latency paths, meeting the needs of latency-sensitive services like financial trading. Network slicing technology allows dedicated network spaces for different services—such as high-bandwidth slices for HD video streaming—balancing security and service quality.
- New MAN architecture is built around edge cloud, leveraging STN networks to form a modular Spine-Leaf architecture for metropolitan networks. This supports integrated fixed-mobile and cloud-network convergence, offering strong traffic offloading and elastic scalability. Regional services are integrated through metro PODs, A-Leaf nodes enable user and edge cloud access, Spines aggregate and forward traffic, and Leaf-Leaf communication uses SRv6 + EVPN for high-speed data transmission.
- The introduction of white-box devices brings transformation—compatible with heterogeneous chips, and more flexible, efficient, and programmable than traditional black-box equipment. This reduces deployment costs and enhances traffic management and policy implementation. In addition, deep integration of fixed-mobile and cloud-network technologies, with 100G backbone bandwidth and dual 10G access, creates a next-generation network ecosystem that combines connectivity, computing power, and applications.
Application Scenarios: Integrating into All Aspects of Urban Life
- Smart Homes: Edge cloud technologies enable services such as cloud gaming, cloud storage, and cloud security. Users can enjoy large-scale cloud games without high-end hardware, and cloud storage ensures secure, on-demand access to data.
- Enterprise Services: MANs provide dedicated lines and VPN services to meet enterprise-level demands. With computing resources, they also offer leasing and cloud services to support digital transformation.
- Urban Public Services: MANs support smart transportation, security, and environmental monitoring, enabling real-time city operations monitoring and intelligent decision-making.
Business Advantages: Demonstrating Competitiveness
- Service Quality Assurance: SRv6 enables customized latency paths and traffic routing, and network slicing ensures differentiated service quality for various applications—ensuring low latency and high reliability for critical services.
- Extensive Network Coverage: The MAN infrastructure covers the entire city—including commercial districts, residential areas, and industrial parks—providing access to a large and diverse user base.
- Cloud-Network Integration: By tightly integrating with cloud resources, users can conveniently access cloud computing platforms such as Tianyi Cloud for data storage, processing, and analysis. Meanwhile, edge cloud deployments bring computing resources closer to end users, reducing latency and enhancing the user experience.
- Strong Security Capabilities: On one hand, network slicing enables service isolation to ensure security across users and services. On the other, ongoing exploration of quantum technologies for MANs offers a more robust foundation for urban network security.
