Overview

Scenarios

Premium BGP provides fast and high-quality public network lines between Chinese mainland and the rest of the world. BGP is used to interconnect with lines of multiple mainstream carriers. Public network connections that feature low latency and high quality are directly established between Chinese mainland and CN-Hong Kong.

• Premium BGP is available only in CN-Hong Kong.
• Premium EIPs can be billed on a yearly/monthly or pay-per-use basis.
• Premium BGP does not support shared data packages and bandwidth add-on packages.

Architecture

This document takes Figure 1 as an example. Suppose you deploy your web application on an ECS in CN-Hong Kong and bind a premium BGP EIP to this ECS. And then users from the Chinese mainland can access your application faster through the optimal path.

Figure 1 Binding a premium BGP EIP to an ECS

In this example, ECS-A is deployed in CN-Hong Kong, and EIP-A is a premium BGP EIP in CN-Hong Kong. To bind EIP-A to ECS-A, you need to:

1. Assign premium BGP EIP-A.
2. Bind EIP-A to ECS-A.

Notes and Constraints

• Each EIP can be bound to only one cloud resource and they must be in the same region.
• An EIP and its bound cloud resource can use different billing modes.

  For example, a yearly/monthly EIP can be bound to a pay-per-use ECS.
