Introduction
When using overseas servers, some users may experience lagging and varying network speeds due to the quality of bandwidth routes. In many cases, users of similar overseas servers experience similar latency conditions. However, differences in routes, such as the use of CN2 optimized routes, can significantly affect network performance, especially during peak hours. This article aims to discuss the three common types of routes used in renting overseas servers: CN2 routes, BGP multilines, and international routes. Understanding these route types and their differences in quality can help users make more informed decisions when selecting overseas servers.
1. CN2 GIA and CN2 GT Routes
CN2 routes represent optimized lines distinct from the traditional 163 backbone network known for frequent network congestion. The 163 network, also known as AS4134 bandwidth, carries 90% of telecommunications traffic and is unsuitable for projects requiring low-latency and zero packet loss. CN2 routes refer to optimized dedicated lines connecting China and overseas destinations, further categorized into CN2 GT and CN2 GIA. CN2 GIA features an independent inbound link, representing a high-end product within the CN2 framework. Users of CN2 GIA enjoy significantly higher speeds and lower latency due to the network’s light load. However, CN2 GIA may suffer from limited outbound bandwidth and vulnerability to network fluctuations and high-volume attacks, in addition to being relatively costly. It is typically suitable for gaming, live streaming, and video websites. On the other hand, CN2 GT, often used at provincial or international nodes with IP addresses starting with 202.97, benefits from international outbound lines, improving performance compared to the 163 backbone network, especially during international traffic routing.
2. Overseas BGP Multilines
Overseas BGP multilines refer to routes that allow switching between different networks to ensure optimal routing and reduced access time for improved speed. IDC service providers may utilize dual-line BGP networks from mobile and China Unicom or offer networks combining PCCW+NTT or China Telecom+China Mobile. The BGP protocol facilitates communication between various networks, and the most recommended configuration is the direct connection to all three major networks, ensuring network stability through redundant connections. This setup enables bandwidth redundancy to mitigate downtime and severe packet loss during network congestion or large-scale attacks. Currently, there are few IDC service providers offering direct connection BGP lines from all three major Chinese networks, with Warner Cloud being one example, providing CN2+BGP direct connection intelligent combination lines to ensure fast and stable network access.
3. International Routes
International routes are commonly used in cross-border e-commerce. When Singapore or Hong Kong servers utilize international routes, users from any international region experience unrestricted access with stable network performance. This type of route is suitable for enterprises with a global audience as it caters to users worldwide. However, users in China may experience high latency due to the route requiring transit through multiple countries before accessing domestic networks.
Conclusion
In summary, this article provides an overview of CN2 optimized routes, BGP multilines, and international routes for overseas servers. Understanding these route types can aid users in selecting the most suitable server for their needs. Testing route performance using ping commands is recommended.
