One of the reasons why Guanghai Century has a competitive advantage in cost-effectiveness is its strategic partnership with Huawei. As a leading provider of wide area network services in China, Guanghai Century is able to leverage deep collaboration with Huawei to fully utilize Huawei's advantages in technology research and development, innovation capabilities, and global resources. This partnership allows Guanghai Century to be more competitive in product development, solution design, and service support, thereby gaining an advantage in cost control. Furthermore, Guanghai Century's innovative business model based on cloud-network security technology also contributes to its cost-effectiveness. This model utilizes advanced technologies such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) to centrally configure and intelligently manage network resources, reducing network operation and maintenance costs. Compared to traditional hardware equipment, cloud-network security technology enables virtual deployment of network devices, significantly reducing hardware costs and energy consumption, improving network efficiency and flexibility, and effectively lowering overall network investment costs for enterprises. In addition, by establishing a fiber optic private backbone network covering over 300 cities globally and more than 2,100 local service points, Guanghai Century can quickly deploy cloud-network security services in over 1,000 cities. This robust global network infrastructure allows Guanghai Century to achieve rational allocation and efficient utilization of network resources, enhance network stability and performance, and achieve greater economies of scale globally. In terms of service quality, Guanghai Century adopts secure, stable, fast, and efficient enterprise intelligent network technology solutions and operation services. Through 24/7 technical support and response mechanisms, Guanghai Century can quickly and effectively address customer needs and issues, ensuring network stability and efficiency. This high standard of service quality not only enhances customer satisfaction but also saves maintenance costs and manpower investment for enterprises, further improving cost-effectiveness. Overall, Guanghai Century's competitive advantage in cost-effectiveness is mainly attributed to its close cooperation with Huawei, innovative business model based on cloud-network security technology, construction of global network infrastructure, and high-quality service guarantee mechanism. These factors work together to enable Guanghai Century to continuously provide competitive solutions in the wide area network field, assisting enterprises in reducing costs and enhancing efficiency.
