In Hong Kong server rental, BGP line and CN2 line are two common network architectures. Here's how they compare:

In the selection of network lines, BGP and CN2 belong to two common types of network architecture, and how to choose according to the specific needs of users, the following is a detailed comparison of CN2 lines and BGP lines, I hope to help you.

Border Gateway Protocol (BGP) :

Features:

BGP is a path vector protocol used to exchange routing information between different autonomous systems.

BGP route selection is affected by many factors, such AS path attributes, policies, and AS paths.

Commonly used on the global Internet, it is a universal and flexible routing protocol.

Advantages:

Global routing can be flexibly selected for various network topologies and connections.

Supports multiple routing policies and filtering rules.

Weaknesses:

For some specific applications, it may not be as stable as the performance provided by dedicated lines (such as CN2 lines).

CN2 (China Telecom NextCarrying Network) :

Features:

CN2 is a proprietary network provided by China Telecom, designed to provide more stable, low-latency and high-bandwidth connections.

More advanced technologies such as MP-BGP (Multiprotocol BGP) are used to improve network performance.

Advantages:

It provides low latency and higher bandwidth, and is suitable for applications that require high network performance, such as online games and video streaming.

Weaknesses:

Compared to BGP lines, CN2 lines may be limited in the flexibility of global routing.

Often targeted to specific markets, it may not be as flexible as BGP lines to adapt to different connection needs.

Selection suggestions:

If your application is mainly for global users and has high requirements for routing flexibility and versatility, you can consider BGP routes.

The specific network bandwidth selection needs to be determined based on business needs, performance requirements and budget, and the actual situation of data center facilities, network infrastructure and service support in Hong Kong should be considered when selecting a server provider.
