In the globalized business environment, fast and stable network connectivity is crucial for enterprises, especially for foreign trade companies that rely on the Internet for international transactions. Understanding and utilizing China Unicom’s backbone network resources and how to enhance access speed and stability through overseas cloud servers are important steps towards success for these companies.

Overview of China Unicom’s Backbone Network

China Unicom has two national backbone networks: AS4837 line and AS9929 line, which serve as the main channels for Unicom users to access domestic and international network resources. The AS4837 line is commonly referred to as Unicom 169 network and is the most commonly used network for home broadband users. Its international export points are located in Beijing, Shanghai, and Guangzhou, and it uses a series of routing nodes. IP addresses on this network typically start with “219.158..”. The AS9929 line is the former China Netcom International backbone network, and while its user base is increasing, the quality of the line has slightly decreased due to the increased number of users.

Comparison of the Three Backbone Networks

  • AS4134: This is China Telecom’s 163 backbone network, which has extensive coverage and stable connectivity.
  • AS4809: China Telecom’s CN2 backbone network, which provides higher-quality network services and is suitable for business customers.
  • AS9808: China Mobile’s CMI backbone network, which is also a powerful network covering the entire country.

Choosing a Backbone Network

For users who need to access servers in Hong Kong and other overseas locations, it is crucial to choose a line directly connected to China Unicom’s backbone network. Such a line typically includes direct connections to the three major networks: China Telecom’s CN2, China Unicom’s CU, and China Mobile’s CMI. This significantly improves the speed of accessing servers from mainland China.

The Importance of Network Optimization

For foreign trade companies, network stability and access speed are the foundation of business operations. Unicom Optimized Line (CU Premium) provides an optimized network path, which is AS4837 line → AS9929 line → AS10099 line. This path reduces network latency and improves the stability of data transmission, making it an ideal choice for international transactions.

The Role of Line Optimization

  • Reducing latency: Choosing high-quality lines can reduce latency when accessing overseas servers, which is especially important for real-time interactive businesses.
  • Improving stability: By using specific optimized lines, it is possible to bypass congested network nodes, reduce packet loss, and improve network stability.
  • Optimizing speed: Direct lines reduce the number of data transfers, thereby speeding up access.

Introduction and Advantages of CUVIP (Unicom Premium Line)

In discussions about network line optimization solutions, CUVIP (Unicom Premium Line) plays a very important role. CUVIP typically refers to an optimized network access route provided for China Unicom users. The routing design of CUVIP is aimed at improving data transmission quality, reducing latency, and enhancing stability, particularly when accessing international network resources.

Introduction and Characteristics of CIA Line

CIA Line typically refers to China International Access, which is the international internet access line in China. This line is designed to optimize access from mainland China to the international internet, especially for business users. The CIA line provides a faster and more stable data transmission channel. By optimizing the transmission path between domestic and international networks, the CIA line ensures efficient network connectivity and a better user experience.
