BGP (Border Gateway Protocol) and CN2 (China Telecom Network 2.0) are two different network connection methods, each with its own characteristics and advantages. Which one is more suitable depends on your specific needs and use cases.

BGP is a common routing protocol widely used in the global Internet. It has high scalability and flexibility, and can provide multi-path routing and interconnection between autonomous systems. BGP connections can provide wider network coverage and better global interconnectivity, and are suitable for scenarios that require a stable connection to the global network.

CN2 is a high-performance network service launched by China Telecom, aiming to provide better network quality and more stable connection experience. The CN2 network adopts an optimized routing strategy, which can achieve lower latency, higher bandwidth and more stable connection performance, especially suitable for data transmission with China or interconnection with Chinese users.

Therefore, if your main users or business needs are concentrated in China, it may be more advantageous to choose CN2 connection, which can obtain better network performance and stability. If your business requires frequent interconnection with the global network or requires wider network coverage, it may be more suitable to choose a BGP connection.

The best choice depends on your specific needs, budget, and options available to your service provider. It is recommended to have a detailed discussion with your Internet service provider to learn about their Internet connection options, performance guarantees and pricing, etc., so that you can make a more informed decision.
