1. The server returns to the country:

　　1.1 Definition and characteristics:

　　The server returns to the country refers to a line connecting the server to a specific country or region network. In China's network environment, the server returns to the country usually refers to a line connecting the server to mainland China network. This is a network architecture chosen to serve mainland Chinese users.

　　1.2 importance:

　　Low latency: The importance of the server returns to the country is that it can provide low -delay services. By connecting to mainland China, the server can respond to domestic users more quickly and improve the user experience.

　　Stability: Compared with the domestic network connection, the return line is more stable, reducing the risk of network interruption and data transmission delay.

　　1.3 Application scenario:

　　It is mainly suitable for applications for users in mainland China, such as e -commerce websites, social media, online education, etc.

　　It is a compliance approach to meet the requirements of domestic regulations and regulatory requirements.

　　2. BGP line:

　　2.1 Definition and characteristics:

　　BGP (Border Gateway Protocol) is a protocol for exchanging routing information in the Internet. The BGP line is not limited to a specific country or region, but is a global route selection through the BGP protocol.

　　2.2 importance:

　　Global Interconnection: The importance of the BGP line is that it supports global interconnection. Through BGP, the network can cross the international boundary and achieve access to global network resources.

　　Elasticity and flexibility: The BGP protocol has the ability to select dynamic routing, which can make real -time routing adjustments according to network conditions and topology.

　　2.3 Application scenario:

　　It is suitable for companies and Internet service providers that need to provide services worldwide.

　　In cloud computing and multinational enterprise networks, BGP lines are usually used to build elastic and highly available network architectures.

　　3. Differences and contact:

　　3.1 Regional:

　　Server return to China: focusing on the network connected to a specific country or region, such as mainland China.

　　BGP line: It is not limited to specific regions and has global connection capabilities.

　　3.2 Service object:

　　Server return line: The main service object is users in specific areas, which are usually used for applications for domestic markets.

　　BGP line: Service objects can be global users, suitable for global companies and service providers.

　　3.3 Configuration and Management:

　　Server return to China: You need to configure the server to connect to the network of the target country or region, which is usually managed by data centers or network service providers.

　　BGP line: You need to configure the BGP protocol to conduct dynamic choices for global routing. Usually it is managed by online engineers and Internet service providers.

　　3.4 Compliance and supervision:

　　Server return to China: Choose in the case that needs to meet domestic regulations and regulatory requirements, which is compliant.

　　BGP line: The specific countries or regions that cannot control the flow of data may need to meet the compliance requirements of multiple countries or regions.

　　The server returns and BGP lines have different positioning and application scenarios in the Internet architecture. The server returns to the country is more concerned about the service needs of specific regional users, and the BGP line provides the elasticity and flexibility of global interconnection. When choosing to use these two, corresponding decisions need to be made according to specific business needs, user distribution and compliance requirements.
